The Evolution of Cable High-Speed Internet

2007-04-18T19:59:00.000-07:00

The computer has altered in modern life beyond our wildest imaginations. Well, I guess I should actually say the PC and Mac. But were really splitting hairs there, either one of these is offering you a fantastic service. Since the mid-nineties, many of us have become accustomed to the home computer. More than likely we have started out with those large bulky desktop units with giant TV like monitors, but an evolution has certainly taken hold. The same can be said about our Internet service. Now a days with high-speed Internet connections we hardly remember those painfully slow dial-up days. It is now the era of cable high speed Internet.

Are you currently using a high-speed Internet service? Are you a fan of DSL or cable high speed Internet? These are common questions recently. This field is very competitive and great deals are to be had. The basic questions to ask are you offering and how much will it cost me? That sounds about right doesn't it? Oh and of course reliability is always a factor. Of course we all want cable high speed Internet, but we don't want a fat bill at the end of each month. Being a fan of cable high speed Internet myself, I have certainly tried my share of services. I first tried a brand called Roadrunner and found that it performed quite adequately. Then, because I moved across the country, I gave Comcast cable high speed Internet a shot. I had no complaints with their service overall.

More recently I relocated again. This time I had no choice but to give the local cable high speed Internet service a shot. I'm sorry to say that it didn't work out too well. While the service worked fine most of the time, the prices were higher than what I had previously experienced and a little bit more than I wanted to pay. This is never good! Shortly after acquiring this new service, I made the decision to go back to Roadrunner, which essentially provided the same service but at a lower cost.

Do you use dial-up? I hope not because I know how slow and unreliable those connections can be. Dial-up is certainly a concept of the previous millennium. And don't you hate that nasty sound when the modem is connecting to the Internet? You could be enjoying cable high speed Internet at a reasonable price? If you have yet to try cable high speed Internet, then I strongly suggest that you check it out. I think you will be pleasantly surprised at the affordable rates that are offered. While some people like to save a few bucks and go with DSL, I don't really recommend it.

I'm on the Internet quite a bit for both work and home use and I have found that there is absolutely no substitute to the speed and quality of service offered by cable high-speed Internet. The whole buzz of technology has worn off, and cable high speed Internet should become the standard bearer for every household so check it out and see for yourself.

What is DSL and How Can It Benefit My Home or Small Business?

2007-04-07T19:22:00.000-07:00

By Scott Pimental

DSL or xDSL is a group of technologies that provide digital data transfer over the telephone network. DSL originally stood for digital subscriber loop, but is now commonly referred to as digital subscriber line. The typical transfer speeds of DSL services range from 128 kilobits per second to 24,000 kbit/s. DSL technology was originally begun as a part of the Integrated Services Digital Network (ISDN). ISDN is a series of protocals designed implemented to allow for digital transmission of voice and data over the telephone networks standard copper wires. This resulted in better speeds and quality than the old analog system.

Most Common Forms of DSL

Asymmetric Digital Subscriber Line (ADSL) is a form of DSL that enables faster transmission of data over these same copper wires than a standard dial up modem can. It accomplishes this by using the frequencies that are normally not used by a voice telephone call, in particular, frequencies higher than normal human hearing.

The drawback to ADSL is that it is ony effective over relatively short distances. The user must be within 5 km of the telephone companies Central Office. Once there, the ADSL signal is stripped off and immediately routed onto a conventional internet network, while any voice-frequency signal is switched into the conventional phone network. This is allows a single phone line to be used for both voice and data transfer.

The most distinguishing characteristic of ADSL is that data transmission speeds are greater in one direction than the other. This is often marketed to small businesses or residential users who are most interested in accessing the internet at an affordable price. It allows for higher download speeds, thus decreasing the users time to view websites and download files. This is not recommended if one has a need to upload large quantities of information or run servers that would require large amounts of bandwidth in the other direction.

Symmetric Digital Subscriber Line (SDSL) is a DSL variant that enables the user to have the same data transfer rate in both directions. This technology has a transfer speed range of 72 to 2320 kbit/s. The primary drawback is that you must be even closer to the telephone companies central office. A maximum distance of 3 km is all that is supported. It is also much more expensive.

Typical DSL technologies include:

High Data Rate Digital Subscriber Line (HDSL), the first DSL technology that uses the higher frequesncy spectrum to transmit data

Symmetric Digital Subscriber Line (SDSL), a standardised version of HDSL

Asymmetric Digital Subscriber Line (ADSL), a version of DSL with a slower upload speed

Rate-Adaptive Digital Subscriber Line (RADSL), A variation of ADSL that adjusts the upstream speed of the connection in an attempt to maintain a specific downstream speed.

Very-high-bit-rate Digital Subscriber Line (VDSL), An improvement on HDSL that Provides a faster rate of transmission speed. It uses up to 4 different frequency bands, two for upstream (from the client to the telco) and two for downstream.

Very-high-bit-rate Digital Subscriber Line 2 (VDSL2), an improved version of VDSL Symmetric High-speed Digital Subscriber Line (G.SHDSL), a standardised replacement for early proprietary SDSL by the International Telecommunication Union

Telecommunication Standardization Sector Powerline Digital Subscriber Line (PDSL), a high speed powerline communications solution which modulates high speed data onto existing electricity distribution infrastructure

DSL Service offers small business customers high speed internet access for a very reasonable rate. Many people don't realize that DSL speeds of 1.5Mbps are the same as T1 speeds which top out at 1.5Mbps. DSL costs $35 per month on average where a full T1 usually costs $400 or $500 if you're in a metro location and up to $1,000 per month if you're in a rural location. Why the high cost for T1 service without the extra speed? A T1 gives reliable service and is not shared with other subscribers or oversubscribed the way DSL is. Because it is not a shared service it carries a high cost.

DSL service offers a slightly less reliable service for a fraction of the cost. If you already have DSL Service you may have noticed that it's fast at some times and slower at other times. This is because it's oversubscribed. Oversubscription means that many people are pulling from the same resource. What does this mean to you? Slow speeds occasionally in peak traffic hours.

Most small business users' biggest concern is price and that's why DSL Service is so popular among them. A few slow periods are a small price to pay for a 90% discount.

Getting Up To Speed With Cable Internet Service

2007-03-22T15:04:00.001-07:00

By Morgan Hamilton

In our modern age, you have a variety of options when it comes to Internet service. While some people crawl along with their slow dial up service, many have discovered the benefits of faster and more reliable DSL or cable Internet service.

These are more expensive than dial up service, but once you made the switch, you will never go back. Cable Internet service is regarded as the fastest type of residential connection, and is far more reliable than any dial up service. Dial up service runs slower when more people in your area are logged on, which does not happen with cable.

If you are choosing between DSL and cable Internet service, your biggest concern will probably be the price. DSL is slower, but offers a good service, while cable will runs faster, but it will be more expensive.

However, cable Internet service offers a feature that DSL does not have: the ability to get Internet phone service. Internet phone can only run through cable, while DSL must go through your phone companies’ phone wires.

It may be pricey, but in the long run it may save you more money when compared to DSL. If you chose to get an Internet phone through your cable Internet service, you will save money on your phone bill. Warner Cable and Vonage are just two of the companies that offer Internet phone. They also offer free domestic long distance calls and the lowest price you can get for your other phone services.

Cable Internet service is also far more reliable than dial up service. You no longer have to wait to connect, you won’t be booted from the Internet, and your connection will be almost always on. The only downside with cable is that when there is no power, you will have no service. Nevertheless, if your computer runs on batteries, this won’t be a problem.

The average Internet user may consider cable Internet service to be too expensive. However, if you access the Internet on most days, own a website, or make a living online, you can really benefit from cable. You should contact the nearest cable company and ask for the best deal.

To Cable, Or To DSL... That Is The Question!

2007-03-08T15:07:00.001-08:00

By Devin Morrison

Well, DSL has distance limitations and Cable is shared by your neighbors.
Both are far better than a dial-up connection that I can guarantee, but price
wise DSL is cheaper and in most instances not as fast. All though DSL is a
more dedicated connection so your speed is more constant. DSL comes in over
your phone lines and operates at a higher frequency so it and a voice conversation
can coexist. You'll need filters to add to your phone lines so there's no buzzing
when making a call, and a DSL modem for your Internet connection. Basically your
phone line plugs into your wall jack and the other end into your modem. The your cat5
cable goes from the modem to the network card located in the back of your computer.

Cable on the other hand comes over coaxial cable which you may already have in your
home if you have Cable TV. Most of the newer homes have coxial cable installed, and cat5 cable, or network cable. That way you can plug your computer in any room. You could also use a wireless router if cat5 cable isn't run throughout the house. For the Internet connection you'll need a Digital Cable
box, and a Cable modem. Usually Cable speeds are faster than DSL unless you upgrade
your package from your DSL provider. Normally DSL speeds start out at 768kbps down, and 128kbps up. Check out this site for more information and to sign-up for either service.

I have been an owner of a small ISP/WISP for over six years. I enjoy working with computers and setting up wireless networks. My greatest distance for a point-to-point wireless connection was 45.9 miles for a local TV station. http://www.dsl-cable-broadband

Cable Vs. DSL - Which is Better?

2007-02-24T16:24:00.000-08:00

By Mark Pascua

As broadband Internet becomes more mainstream, one of the most common questions we get is: which is better, cable or dsl?

The answer to that question is not so definite. Many factors come into play when deciding which high-speed connection to choose. Regardless of which you choose (DSL, Cable, or even Satellite) it’s going to be a ton better (and faster) than that ancient dialup modem you’ve been using. Not to mention, your Internet experience will be much more enjoyable.

DSL (Digital Subscriber Line)

Just like your existing dialup modem, DSL uses your existing copper wire phone line to deliver data at high speed. To qualify for DSL, you need the following:

- a phone line

- a DSL modem (which normally comes with the service)

- an Ethernet card or an available USB port ( most DSL modems allow both connections, but Ethernet is recommended).

- a phone company (ISP) that is offering DSL service (e.g., Verizon)

One important factor that will influence your DSL connection is the distance between your home or office and the phone company’s central office. The farther away you are from the central office, the signal becomes weaker, thus a slower connection. With that said, DSL is not as available widespread compared to cable. You’ll need to contact your local phone provider to check availability.

Speed wise, depending on the package you choose, DSL can range from 128 kbps to 3 Mbps. Generally, the faster your connection the more expensive your service will be. You can expect to pay around $25-$30 a month for a 768 kbps connection, which is roughly 13 times faster than a 56k dialup modem.

::Pros::

- Relatively cheaper than cable

- Dedicated line, so speeds are almost guaranteed

- You can talk on the phone at the same time while surfing the net

::Cons::

- Slower speeds compared to cable

- Speeds drop the farther away your home/office is from the central office

- Not available in all areas

Cable Internet

Cable Internet gets our recommendation. Cable, which you can probably already tell, uses the coaxial cable that your television uses. To qualify for cable internet, you need the following:

- a cable modem ( which normally comes with the service)

- an Ethernet card or an available USB port (most cable modems allow both connections, but Ethernet is recommended)

- a cable company offering cable Internet (e.g., Adelphia)

Unlike DSL, cable Internet does not depend on the distance between your home or office and the central office. However, unlike DSL, cable connections are typically shared among your neighbors. Although, most cable companies provide pipelines with huge bandwidth that this rarely becomes an issue.

Speed wise, cable Internet typically ranges from 3 Mbps to 10 Mbps, up to 3-4 times faster than DSL. However, expect to pay more for the service - $40-$50 per month.

::Pros::

- Faster speeds than DSL

- More widespread than DSL

- Distance does not affect speed

::Cons::

- More expensive than DSL

- Line is shared with other users

With all that said, you need to think about what type of user you are. If you are a heavy Internet user and downloader, you would highly benefit from a broadband connection. For the light users who use the Internet just to check emails, are probably better off with a dialup. However, if you are willing to splurge some cash on a broadband connection, then by all means, upgrade!

How to Test Your DSL and Cable Internet Connection Speed

2007-02-22T12:06:00.000-08:00

By George Chamoun

There are two measured elements that determine your internet connection speed. They are: The download rate, and the upload rate of data measured in bits per seconds. Usually, it is expressed in Kilobits per second.

A bit is the smallest piece of data that can be stored in a computer. The bit can be either "0" or "1". The byte is eight bits. Example of a byte and bits are the following:

bit= 0 or 1

byte=8 bits

1 byte=10011101 (eight bits)

A single charcter needs one byte or eight bits to be stored in a computer. So, when the data rate is 1 byte/sec, that means one character per second is the rate at which data is transferred through your connection.

This is very slow, and only intended for an example. In order to browse the internet, you must have at least a dial up access with a 56kb/s modem, in order to get a meaningful and practical result.

There are different types of internet connection. First they introduced the dialup connection using your phone line, then the broadband was introduced.

The broadband internet connections are DSL, Cable, or Satellite internet services. They are widely used and expanding due to the high bandwith.

When you get an internet service, your provider states that your speed will be a certain numbers. They usually give you a good idea, but not an exact one. The common asked questions
among internet users is:

How do I know what is my connection speed, and if I am getting what I was promised?.

If there anyway I can test my connection, and do I need to buy expensive software to test it?.

The answer is simple. There are two ways to test your internet connection speed:

1- The manual simple calculation test that you can do yourself without any software or third party services.

2- You can find a service that lets you run a test through their servers, and get your numbers displayed at their webpage.

1-The manual method:

Since I mentioned that the connection speed consist of two numbers, the download and upload speed. So, what you do is download from the internet any free software, and watch the result box with the result that show the size of the file and how many seconds it tool to download.

When you are done recording the download speed, upload a file of a specific size (1 Mb, 2 Mb), and time your watch when you start. When the file is uploaded, check your watch and record the time it took for the task. Then divide your file size by the seconds it took.

If you file was 2 Mb. that took 5 minutes to upload, then your upload speed is 2 Mb./300 sec. or 6.826 Kbits/sec.You can run the above test couple times, and then take the average for a better result.

2-The automated test at a third party service:

This is my preferred one, where you get to a website where the test is done for you. It is done using a script installed on their server, and letting you download and upload to their server a test file (invisible to you). Then, the result is displayed on their webpage. You just have to register for free using your email. It is free. This is a website address where they offer you a free internet connection test:

http://www.visualware.com.

In summary, don't settle for numbers given to you by your services, do the tests whenever you can. You enjoy it, and feel that you are getting your money worth. This is because some servcies charges you 35 dollars or more for a high speed internet service.

Thanks,

George Chamoun

How Does Broadband Work?

2007-02-17T17:13:00.001-08:00

By Van Theodorou

These days, "broadband" is a word that is thrown around easily in telecommunications and internet lingo, but the average consumer may not have a clear understanding of how broadband works. It's easy to understand why; the technology industry even has trouble defining it clearly. So how does broadband work? The online Webster's dictionary defines broadband as "A class of communication channel capable of supporting a wide range of frequencies, typically from audio up to video frequencies. A broadband channel can carry multiple signals by dividing the total capacity into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies." Let's take a look at each part of the definition to understand how broadband works.

The first part of answering the question 'how does broadband work' is to think about the phrase a "class of communication channel." We can gather from this that it is different from the normal class of communication channel that we use - our regular phone lines. Phone lines, also called baseband lines, normally carry 29.6kbps of analog data when used for voice communications. But with the advent of the internet, people began to demand faster data transmission. A regular, baseband phone line can carry up to 56kbps of data with the help of a high-speed modem, but without additional technology, that is its maximum capacity.

That wasn't nearly fast enough to keep up with the average person's demand for and dependency on the internet, which led to the demand for broadband. So how does broadband work? If you think of a baseband line as having one "channel" to send information, you can think of a broadband line as having multiple channels that you use at the same time. Not only that, but a broadband connection is capable of carrying a wider range and type of frequencies, meaning different types of data. And what it can carry, it carries faster. When you drive on the interstate, what happens when there aren't enough lanes for the number of cars on the road? Everyone is forced to go slower.

The same happens with the internet. Think of your connection to the internet as a tunnel that links your computer to the internet. A regular phone line can allow only a small amount of data to pass through at a time. In comparison, a broadband is a wider (or broader) tunnel, allowing a greater amount of information to pass through your connection at one time. The breadth of this tunnel is called "bandwidth." The more bandwidth you have, the faster you can move data. With broadband service, you can also download files that require a great deal of different types of frequencies as well, such as audio and video files.

This is a partial answer to the question 'how does broadband work,' but the other has to do with the way that broadband services can compress and transmit that data that you're sending. Go back to the cars on the interstate analogy. What if suddenly all of the cars could be miniaturized? What would that do to the traffic jam? Or if they could use all of the space available in the tunnel - above your head, between cars, etc. Broadband technology not only widens the channels you have, but it uses them more efficiently. Meaning you can get more out of the bandwidth that you have. Broadband makes your internet experience faster and more efficient overall.

Broadband is State-of-the-Art Internet Access: How Can a Broadband Cable Benefit You?

2007-02-03T23:24:00.000-08:00

By David Gonzalez

We are now well ensconced in a time when the Web is riddled with graphics, animations, sounds, and videos, bringing about a necessity for superior internet access such as that which broadband can provide. The fact is that anything less than the speed supplied by a broadband cable has become inadequate for today’s Web users.

Of course, if you use the internet only once every so often, you wouldn’t be as heavily dependent upon high-speed internet access as is provided by broadband, however, if you’re a regular user, it’s virtually a necessity.

But wait a minute…even though you use the internet, it doesn’t mean you know exactly what this high focus form of internet access actually is. So lets start there. In essence, broadband is a very fast form of internet connection. Broadband Will provide you with a noticeably faster internet speed than a dial-up connection.

Broadband used to be a challenge only because of it’s limited availability, however, today there are many ways that you can have a much faster connection. The delivery methods of broadband have been expanded to the following types of broadband cable:

- Copper telephone wires

- Cable TV wires

- Radio microwaves from local base stations

- Satellite microwaves from geo-stationary satellites

Now lets look at why this faster style of internet access is actually better. The benefits of broadband actually include much more than faster downloads. Broadband is the connection that is always “on”. As soon as you start up your computer, it’s already connected to the internet. For anyone who has waited for a modem to dial up and connect, the advantage of this is quite apparent. Furthermore, broadband allows you to download movies, music, and web pages that were virtually inaccessible in practical terms when using dial-up.

But the benefits of broadband aren’t just felt by individual users. Businesses, governments, schools, and communities can all experience the superiority that broadband cables can provide.

Here are some examples of benefits for each of those types of organizations:

- Businesses will notice an increase in productivity when large data files transfer quickly and directly among local and head offices, no matter the distance between the locations. Moreover, with the popularity of net-meetings and videoconferencing, a face-to-face meeting becomes entirely possible without the travel costs.

- Schools can now offer equal opportunities to their students no matter their location or funding. A student in a remote community is now able to use a broadband connection to receive violin lessons from the same revered instructor as a student in a large city. Moreover, rural students can take virtual field trips and see the same fascinating and educational museums as city kids.

- Local governments are now enjoying broadband benefits that let them provide one-stop shopping for town business transactions, as well as licensing, permits, billing, and utility payments.

- Communities have been quick to jump on the broadband band wagon to promote their local historical and other various tourist attractions. No other marketing resource reaches as far and as effectively as the internet.

There are so many fantastic benefits to a high-speed, broadband internet connection, that it is becoming as “basic” a need as a computer in today’s society.

Broadband DSL Compared to Cable Modems

2007-01-29T14:05:00.000-08:00

By Robert Thatcher

The speed of incoming and outgoing internet computer data can vary between broadband DSL and cable modems. Understanding how cable modems operate in comparison to DSL provides a better understanding of why broadband DSL is the preferred choice in broadband technology.

Cable modem internet service is used mainly in residential settings rather than for business use because it is usually offered as a package deal with cable television programming. Cable programming uses separate channels within one main cable for television broadcasting, outgoing internet computer data
from subscribers, and incoming internet computer data to subscribers in specific locations. Unlike DSL, all cable television and internet subscribers in a specific location share the same cable to and from the provider. This means that every cable subscriber sharing that single cable also share bandwidth. The speed of internet service via a cable modem doesn't depend on
the distance to and from the provider. It depends on the number of other subscribers on the same cable who are using the internet simultaneously.

Broadband DSL allows subscribers to use the same telephone line for telephone communication and internet access. Broadband DSL uses frequencies that go way beyond the frequency range of regular telephone service, so data transfer speed with DSL is considerably greater than other options. Unlike cable modem
internet service, the speed of broadband DSL depends on the distance the provider is to the DSL subscriber and connection speed chosen by that DSL subscriber. DSL is generally faster than broadband cable modem service because of greater amounts of bandwidth availability. Broadband DSL is a dedicated internet link that can be counted on for speed and reliability.

DSL is clearly the best choice of broadband technology for the general public as well as businesses relying on fast connections and internet downloads. Internet users can rely on broadband DSL for faster internet browsing, game plays, and emailing, as well as all other internet-based activities.

Cable ISPs

2007-01-24T14:58:00.000-08:00

By Kevin Stith

Various companies today provide Internet services in a number of mediums that depends upon the various geographical and demographic factors. The mediums for Internet services include satellite, cable broadband, ISDN, DSL, and dial-up.

The cable Internet service is provided by a tie-up between the local cable TV company and an ISP (Internet Service Provider). A television signal occupies 6 Mhz on the coaxial cable, which is used to deliver cable television signals. There is a lot of unused space left over in the coaxial cable that can deliver broadband Internet.

Cable Internet speed is inversely proportional to the number of users. This causes the speed to deteriorate during peak hours. The cable company may offer a discount for ordering both cable TV and cable broadband service from them. However, a survey report states that 24% of all cable connections need to be repaired at some point or the other. DSL connections are comparatively better, where only about 12% need to be repaired.

A modem is usually provided free of charge with the package, which can be either external or internal to the CPU. It can even be a part of the set-top box.

To connect to Internet at much faster speeds, cable modems use existing cable-wire network. As the same line is shared with other users in the area, it could lead to congestion problems and other such performance related issues. The speed is much higher in the case of DSL and not too expensive either.

Cable networks share the line that compromises on privacy. Hacking tools are easier to use on cable modems. It is possible to access secure information through them.

In a recent ruling, the FCC (Federal Communications Commission) classified cable-modem service as an ?informative service?, thereby distinguishing it from cable or telecommunication services. This means that now the large ISPs do not have to share their network with smaller competitors.

Cheaper Broadband: How to Find the Broadband Deal which Suits YOU?

2007-01-22T19:07:00.000-08:00

By James Dyson

With new ISP providers entering the market every day, the prices to get a high speed connection are falling. With so many to choose from, how do you decide broadband supplier offers the right package for you?

Connection Speed - How fast?

Be a little bit weary of broadband deals advertising "up to 8mb" connection etc. It may not mean that you will get the speed they advertise. The speed you will be able to get depends on your local exchange and what your line is capable of. So always check the availability before you sign on the dotted line.

Download Limits – The "Unlimited broadband" myth

Many ISPs advertise "Unlimited Broadband" as their unique selling point. Even these so called "Unlimited" download limits do have fair usage policies (usually not well advertised, like most small print). If you use your broadband internet connection just to browse internet, check emails and do some shopping, you may not need a huge download limit or an unlimited deal for which you have to pay more. One of the common impacts of advertising these days is to make you believe that you need something which in fact, may not be true. So know what download limit you need and do not end up paying over the odds because of seeing a flashy advertisement from an internet service provider.

Know your rights

Most of the products you buy online, including your broadband connection will be subject to some cooling off period. Even if you sign up to a one year contract, you may still be able to cancel within, say 14 days or so depending on local regulations.

Compare prices and read consumer reviews

Broadband providers keep changing their offers all the time. If you have seen an advertisement somewhere, whether it is TV or media, do not presume that you will get the same offer. Always check the latest prices when you sign up. You can read what other peoples experiences are with the Internet service providers using broadband provider comparison sites.

Last, but not least, consider looking for a latest deal every time you renew your contract. There is a good chance that you might find a better ISP than your current one.

Every time you change your broadband contract, you might find it useful to Compare Broadband Supplier offers and read Broadband ISP reviews before you sign up for your connection.

Evaluating Bandwidth Choices-OC3 vs OC12 vs OC48

2007-01-15T20:01:00.000-08:00

By Michael Lemm

Looking for bandwidth? That can be a daunting and frustrating task even in the best of situations. There's lots to consider in order to make the right decision for your needs. Below you'll find some help when evaluating OC3 vs OC12 vs OC48. Factors covered include Technology, Speed, Description, Application, Pros, Cons, and Cost.

~~~~~~~~~

Technology: OC3

Speed: 155.52 Mbps

Description: Optical carrier (fiber) connected by equipment capable of speeds up to 155.52 Mbps.

Application: Large enterprise or ISP backbone.

Pros: Extremely high speed and throughput.

Cons: Extremely high cost.

Costs: Expect cost of an OC3 to start at around a $10-30,000 for a stable, reliable system (e.g. from a Tier 1 provider).....not including local loop or extensive setup. However....the pricing for these connections can vary widely depending on the carrier, location of service and the application for which the connection is being used. For example...Tier 1 providers may cost more than local/regional Tier 2 and Tier 3 providers but are much more stable and reliable. A Tier 1 provider should always be the provider of choice for any business serious about the quality of their OCx network.

~~~~~~~~~~

Technology: OC12

Speed: 622.08 Mbps

Description: Optical carrier (fiber) connected by equipment capable of speeds up to 622.08 Mbps.

Application: Large enterprise or ISP backbone.

Pros: Extremely high speed and throughput.

Cons: Extremely high cost.

Costs: Expect cost of an OC12 to start at around $1-300,000+ for a stable, reliable system (e.g. from a Tier 1 provider)..... plus several hundred thousand dollars in setup costs. However....the pricing for these connections can vary widely depending on the carrier, location of service and the application for which the connection is being used. A Tier 1 provider should always be the provider of choice for any business serious about the quality of their OCx network.

~~~~~~~~~~

Technology: OC48

Speed: 2.488 Gbps (Gigabytes per second)

Description: Optical carrier (multiple strands of fiber) connected by equipment capable of speeds up to 2.488 Mbps.

Application: Large enterprise or ISP backbone.

Pros: Extremely high speed and throughput.

Cons: Extremely high cost.

Costs: Expect cost of an OC48 to start at around $3-500,000 for a stable, reliable system (e.g. from a Tier 1 provider)..... plus several hundred thousand dollars in setup costs. However....the pricing for these connections can vary widely depending on the carrier, location of service and the application for which the connection is being used. A Tier 1 provider should always be the provider of choice for any business serious about the quality of their OCx network.

T1 Providers with Fast Connections

2007-01-10T17:33:00.000-08:00

By Groshan Fabiola

If you are looking for T1 providers to bring a reliable high-speed connection to your company, you have come to the right place! The first thing to know on your search is that a business-level T1 connection is a favorite choice for small-to-medium sized businesses that need to transfer files quickly and efficiently. Over the last few years, the price of T1 connections has dropped considerably, allowing large and small companies to explore the world of broadband.

You should also know that there are two options for T1 access. One is that you can work with an Internet Service Provider directly or work through a broker. It is easy to go straight to an ISP if you know exactly what your business needs are. You just need to locate the available T1 providers in your area and find out what services they offer, how much they cost, and how you can upgrade your Internet solution over time. It can involve some tedious legwork, shopping around for the best price and service, but you get to make direct comparisons and talk to providers yourself.

In addition, an Internet access broker might be helpful in helping you find the right provider. Brokers offer expert help in comparing the multiple providers. They will explain what the T1 providers in their network can offer your business, the level of customer service and support you can expect, and the prices you will pay. Before you work with a broker, here are some quick things to keep a couple things mind such as the fact that you do not have to pay for a T1 broker's services.

Remember that they make a commission from the T1 providers they work with. If your broker says he has had satisfied customers, do not take his word for it - find out direct from the source. Brokers should willingly provide you with a list of companies they worked with that were happy with their service. Make sure to ask references if the broker answered questions, resolved problems quickly, and provided a pressure-free buying experience.

It is also a good idea to query how long the broker has worked with certain providers. Typically, if a broker works with a network of T1 providers for a long time, the broker has a better understanding of the offerings that would best suit your business. Remember to look for the best combination of service and price, not necessarily one over the other.

You also want to make sure everything from the installation date to the speed and uptime of your service is documented. Also, make sure there are not any hidden service fees. Considering how important a reliable Internet connection is to your business, a broker should offer 24/7 live person customer support. They should also monitor your Internet setup remotely and install any upgrades.

Ten Tips On Switching Broadband

2006-12-16T22:18:00.000-08:00

By James Bergin

You wouldn’t think twice about shopping around for the best value gas and electricity, so why pay over the odds for your broadband? The Office of National Statistics estimates that more than 13 million people in the UK have access to the internet at home, with 73 per cent of those choosing broadband.

Whether you’ve had poor service, an unreliable connection or are just tired of paying too much for your ISP, switching broadband provider can save you money and get you a better service. Simply follow our 10 tips to get the most out of your broadband.

1. Ask for a better deal

It may seem obvious, but simply asking your current provider for a better deal could be the answer. As the market continues to become more competitive, companies have to work harder to keep their customers.

The average 1Mb connection cost £50 in 2003; by the end of 2005 it was only £16. So if you’ve had your contract for some time, chances are that you could get the same thing for a lot less just by asking for it. You never know, so try your luck and ask for the latest deal.

2. Your rights

Check: Is your supplier signed up to the Migration Code of Practice? This voluntary agreement between providers works to fairly facilitate the “migration” of customers from one supplier to another. Your current provider will issue you with a Migration Authorisation Code (MAC), which you then pass on to your new provider, allowing them to set up your service without a break in your connection.

Your new provider must also be signed up for the MAC code to work. The code is not applicable to services delivered by cable, such as ntl or Telewest. See Ofcom’s website for more information on the Migration Code.

If your provider isn’t signed up to the Migration Code you will have to cancel your current contract before you can set up a new one. This means that you will have a break in your service and will either have to go without, or return to dial-up until broadband has been reinstalled in your home.

Check: Are you free of your contract obligations? If you have signed a contract you have to see it out or incur a cancellation fee, even if your current provider is signed up to the Migration Code of Practice. If you’re unsure of your contractual duties, contact us and we will check for you (note that this is not legal advice).

Check: Read the details of your warranty – has your supplier made a service agreement they may have breached? If so, you might be able to terminate your contract with them on these grounds, but make sure you read the small print.

3. Keep a log

If you’ve been having trouble with your broadband connection, make sure that you keep a record each time you experience a problem. Take a screen grab of your error message, or keep a detailed written log.

Keep a diary of calls made to customer services; who you spoke to and how long you had to wait. Calls to premium or 0870 numbers can be expensive – for example, 10 calls for 10 minutes at 15p per minute is £15. Call costs to customer service centres can range from free, up to £1 a minute, so check first and keep your phone bills as a record of the total call charges.

This information may be crucial evidence if you want to cancel when you still within your minimum contract period.

4. Otelo and Ofcom

If you are having service problems and want to switch provider but are having trouble doing so, you can write an open letter to Otelo, the office of the telecommunications ombudsman. 33 per cent of ISP providers are members of the body, which was set up to investigate complaints made by telecommunications customers. While the service is free for members of the public, it will actually cost your supplier money to be investigated, so you will be taken more seriously if Otelo get involved.

If your supplier isn’t a member of Otelo, you can still write to Ofcom, the independent regulator for the UK, for help.

It’s always a good idea to send a copy to the head of customer services at your supplier.

5. Keep the pressure on

Being on hold for long periods of time and then getting nowhere can be disheartening, but don’t give up. Ring regularly, stay cool and don’t be abusive.

Make sure that you are well organised and have your facts to hand – you could also offer to post factual evidence of your problems.

For £12.75 a quarter, you can get easily accessible, reliable legal advice from the Which? Legal Service, so you can make sure you know your rights before relaying them clearly to your service provider.

6. Make yourself heard

If none of this works get in touch with the papers. But make sure you have your facts straight before you get the media involved.

7. Complications

The type of broadband you currently have could limit your choices. If you are currently with ntl, Telewest or Kingston, then you have a cable connection and will need a mobile or landline if you want to switch to 3G or ADSL MAX.

If you want to do an LLU to LLU swap you will find that there is no migration procedure in place and that, having invested heavily in LLU technology, your supplier will try to hold on to you.

8. When is free really free?

Before you switch, make sure you have checked out any hidden costs in your chosen package. If you are considering a cheap or “free” broadband deal, take into account the quality of service you will be getting. Your new contract might also have a download limit which could mean that you to end up paying more than your monthly rate for big downloads.

9. Think about service

There is more to broadband than a cheap monthly charge. Consider the opening hours and costs of the call centre on our calculator.

For example, Talk Talk have recently come clean about over-stretching their customer service operation, so make sure you do your research and read customer reviews before committing to a contract.

Broadband Internet Access - In The Age Of Broadband Technology Rapid Development

2006-12-12T17:50:00.000-08:00

By Ske Chay

Broadband technology development from low speed modems to broadband internet access as well as broadband telephone connections make substantial differences in our lives.

In this age of rapid growth and transformation, regardless of whether in science, technology, transportation or diffusion of information, speed is the driving force behind each tremendous change in advancement. With the innovation of broadband access, we are connected at a neck breaking speed and tasks can be completed within a few seconds.

The internet has made astonishing contributions in the transmission and communication of data and information as well as making it possible for business to be conducted in every corner of the planet. Business partners such as the buyers, sellers or agents do not have to meet together in person to discuss and agree on their business arrangements. They make use of modern technology as tools of communication, broadband internet access being one of them.

However, before the introduction of broadband internet access, access to the internet was restricted and limited to dial-up connections only. In addition to the cost of installing a separate telephone line for the access, it is also very time consuming. Uploading and downloading of information or files were done at a snail's pace, with a low speed 28.8 Kbps modems.

Basically, broadband internet access is a high capacity and high-speed transmission medium. It provides the user with a low cost but higher data-transmission rate internet connection in terms of speed but with no compromise on the quality.

Broadband internet access transfers data over a broad bandwidth connection from multiple independent network carriers. This broadband technology is usually done by establishing the different bandwidth channels on fiber-optic cable connections, through telephone lines or via complex satellite systems. These huge volumes of data are transmitted in the form of signals. Such connection supports a wide range of frequencies and usually allows two or more signals to share a medium simultaneously.

The biggest effect of broadband access is in the transmission of data, video and voice over long distances. It is ideal for a variety of different purposes such as streaming multimedia including the downloading of large files of video pictures, movies, music and various forms of computer games as well as the broadband telephone connections or VoIP.

The broadband internet access provides broadband telephone connections of high quality long distance conversations. This is a type of voice based communications system and is more efficient as well as very much cheaper than the traditional telephone line. The accessories needed are a broadband connection, a connecting adapter and a normal touch-tone telephone. The broadband technology is a cost saving instrument for communication through voice and video.

Just What Is A Bonded T1 And What Does It Give You

2006-11-25T00:20:00.000-08:00

By Michael Lemm

When designing your LAN or WAN the logical solution in relation to your expected usage may often indicate multiple T1 lines. In this case bonded T1 could be the best choice. However, before you jump you need to know just what a bonded T1 really is and what it can....and can't....do for you.

A bonded T1 just means that the you have two T1 lines (from the same provider) which have been joined together in a special way so that you can use the combined total of 3.0 Mbps of Internet data or the 46 channels for voice/phone use. You cannot bond T1's together if they are not through the same provider.

If you were to have two T1's, unbonded, then you could not use the full 3.0 Mbps of bandwidth all at once. For example, if you did a speed test, you wouldn't be able to get a result of "3.0 Mbps", the max you could download/upload at any one time would be 1.5 Mbps, even though you had two T1's. I know it doesn't make sense because you think that 1.5+1.5=3.0. It doesn't work like that. Unless your T's are bonded, you can only use the 1.5 Mbps of bandwidth that each line provides....seperately. You can do two download tests, at separate download test sites, and get a full 1.5 Mbps reading at each download site. But with out bonding, there isn't a way of getting a test result of 3.0 Mbps. Think of it in terms of cars: You can either have two slow Datsun pickups or one Ram 4x4 with a 5.7L Hemi. Sometimes, two slow pickups are better for reliability than one big Ram 4x4, but not as big and fast.

There are exceptions to this of course, and there's probally better ways of explaining it, but this will give you a general idea.

You can bond quite a few T1 together by the way, you're not limited to just two. The maximum is usually around 4 T1's although some have gone as far as 8. However, if you go beyond 4 bonded T1's it makes much more sense to start looking at a fractional/burstable DS3. That decision than rests on the combination of capability requirements and cost efficiency in relation to the intended application(s).

It's best that you use the services of a telecommunications consultant to walk you through all of your choices for network design utilizing a bonded T1. If you need more than what a bonded T1 can provide....such as a fractional or full DS3....you should also make use of consultant srevices. Many such services are usually no cost to you....and will enable you to more effectively and efficiently find the best solution for your specific application(s).

What is ADSL?

2006-11-14T17:53:00.000-08:00

By Ross Bainbridge

ADSL is a relatively new technology that stands for Asymmetric Digital Subscriber Line. ADSL is more commonly known as just DSL. It can provide a very fast transmission of video and voice to homes over ordinary copper telephone wires. It requires a special DSL modem to function.

ADSL modems transmit faster than conventional modems. They are generally designed to be the most cost-effective way to provide high-speed Internet access to areas with low market penetration of high-speed cable Internet access. Thus, it is its primary competition.

Differences between DLS types

Unlike other forms of DSL, ADSL has an asymmetric high-speed data flow, meaning that it can process data flow at high speeds in only one direction. Providers market ADSL as a way to access the Internet and download at very fast speeds without needing to run servers that would require bandwidth in the other direction.

Technical Statistics

While a conventional dial-up modem can only download up to 56 kbps per second, the ADSL modem can download at the rate of 256 kbps and can typically go as fast as eight mbps. While the download speeds are very high, the upload speed of the ADSL is comparable to dial-up modems. The ADSL starting upload speed is around 64 kbps and can typically go as fast as 256 kbps. Your upload and download speeds will depend on your distance from the provider?s central office or remote terminal.

The ADSL is relatively slower than today?s cable modem when it comes to both download and upload speeds. However, cable modem connection is sometimes limited to certain areas and not available in smaller markets. In these places, if people want to have high speed Internet they have no choice but to use ADSL. Typically, you can get more information on ADSL and ADSL servers online.

ADSL Speed Tests

2006-11-11T21:11:00.000-08:00

By Ross Bainbridge

ADSL is a new technology that stands for Asymmetric Digital Subscriber Line. This is commonly known as DSL and can provide high speed internet access to homes using the standard copper telephone lines. It is different from Internet access that is provided through cable television lines.

DSL is the primary competition of cable in the Internet service provider market. The primary advantage of cable is that it has faster and more flexible download and upload speeds compared to DSL. While DSL can provide you with a fast download speed, it is only one-way. Its upload speed is significantly slower than what cable can provide you. This is why DSL is primarily marketed to passive Internet users, meaning those who do not need to upload files frequently.

DSL does have some advantages over cable. Its lower cost and wider range of availability might appeal to more prudent consumers. In smaller, lower-market cities, cable Internet access might not be available. These are places where DSL is more popular.

How do I test the speed of DSL?

You can test the speed of your Internet access by going to a website that offers this service. By sending your computer an information packet, which your computer will, in turn, send it back to them. The website will then measure the time it took your computer to download and upload the information packet and calculate the speed of your bandwidth.

This test will measure the ?actual speed? and ?true speed? of your internet access. Actual speed is the amount of useful data that your connection can transmit or receive per second. On the other hand, true speed also includes non-significant data along with the useful ones. True speed is not used when rating broadband speed rankings. Only actual speed is used for this purpose.

A typical DSL connection will have download speeds of four mbps and upload speeds of six kbps. Cable can offer download speeds of up to eight mbps and upload speeds of 355 kbps.

High Speed Internet - DSL Advantages & Disadvantages

2006-11-05T15:35:00.000-08:00

By Frank Owen

High Speed Internet Advantages

DSL is just one of many ways to connect to the net. There are many advantages DSL has to offer other forms of Internet connection. One of the most obvious advantages is DSL offers a fast connection. Rather than wait hours for a document to download using dial up, with DSL you can download large files in just minutes. Here are some other advantages DSL has to offer high speed Internet fans:

DSL allows you to use an open Internet connection and use your telephone line for phone calls at the same time.

DSL speed is typically a lot faster than a traditional modem and doesn't require new wiring. In fact you can usually use the phone line you already have installed in your home to get DSL up and running.

Most companies provide you with a DSL modem during installation as part of the DSL package.

If you own your own business you'll be able to upload and download large files much faster using a DSL connection.

Disadvantages of DSL

Of course, there are disadvantages to anything as is the case with DSL. While most users consider these disadvantages minor they are nonetheless worthy of note:

The closer you are to the central office of the DSL provider the better your connection will work. Thus if you are located far away you may have more trouble connecting using your DSL line.

Typically connection speeds are faster when receiving information and data than when sending data using a DSL connection.

Compare Cable vs. DSL

2006-10-23T16:19:00.000-07:00

By Bradley James

Okay, so you are finally tired of those slow dial-up internet connections, and you want to go broadband. Good deal. But first, you may be wondering which type of broadband connection is best- DSL or Cable? Or, at least, which of the two gives you more speed for the price? Here we take a look at these two popular broadband connections and try to determine which one is better: DSL vs. Cable.

Cable Speed vs. DSL

The most common question that comes up is which type of connection is faster, DSL or Cable? To answer this, it is important to compare both upload and download speeds. Now, so you have something to compare these speeds to, your average dial-up connection is about 28 - 56 Kbps. Most often, however, you won't be able to get 56k through dial up, as most services can not handle this speed.

The average speed of a DSL download is 1.0 - 1.5Mbps. That's megabytes per second - about 20 times as fast as the fastest dial-up connection. This is fast, but consider Cable, which can give you up to 2 - 3Mbps. Thus, at least for downloading, cable can give you almost twice the speed of DSL - that's impressive. On the upload side, however, cable and DSL are pretty evenly matched. They both provide about 100Kbps - 400Kbps. It seems that cable has won this battle.

What about Price and Quality of Service?

There is more to discuss here besides the speed of the connections. Take price for one. Cable and DSL connections are both going to be more expensive than dial-up. But, DSL seems to be the cheaper of the two at the moment. You can get a good DSL internet connection for about $35 - $45 per month. Cable modem will cost you about $45 or $50 (this price may be included in a cable TV package). These prices, however, are really close and they change almost from month to month.

DSL is nice because you can talk on the phone and be online at the same time. In addition, business-level DSL service provides guaranteed data rates, so your connection speed is never a surprise. On the other hand, DSL speed tends to decrease the further you are away from the data center, and it is typically not as widely available as Cable. Cable speeds are not dependent on distance from the data center, and is occasionally cheaper than DSL when included in a cable TV rate. A cable modem, however, may require costly professional installation, and there may exists some limitations on downloads and uploads. All of these factors should be taken into consideration when choosing either broadband service.

Broadband: Just The Facts

2006-10-20T20:53:00.000-07:00

By David McFarlane

What Is Broadband?

Traditional Internet is called dial-up, because it works through dialing the phone line to access the Internet. Broadband Internet access provides a higher speed of transmitting the data to the user. The line carrying the data can therefore carry more information to the user than dial-up.

The new and latest consumer broadband implementations of up to 30 Mbits per second are considerably faster and more economical than the ones that were available when the Internet first became popular such as the ISDN and 56 kbits per second. They are also different prices charged depending on the geographical locations, spread over different countries. The main reason for naming these fast connections as broadband Internet is because of the unusually high speeds of transmitting data, which in turn, is due to being able to send different amounts of data concurrently.

In general electronics and telecommunications, any signal or circuit that consists of or handles a broad range of frequencies is known as broadband. This is a term that is used relatively and is best understood in the context of wide frequencies.

Will I Be Able To Get Broadband?

The sad truth about today’s broadband Internet technology is that not everyone has easy access to affordable broadband. People in rural areas must often resort to expensive satellite broadband if they are going to have broadband availability. The government feels that broadband should be available to all Americans, and several agencies are taking steps to ensure that this occurs in the near future.

What Kind Of Broadband Options Do I Have?

When it comes to broadband Internet, there are actually several different options you have to choose from, including: DSL, cable, and satellite, as being the most recommended. DSL, or digital subscriber line, uses a phone line to carry digital signals directly, without having to convert them over to an analog signal first. Through DSL, you can attain much higher data rates than with a regular modem, your connection will always be on which means that you will not have to dial-up every time you wish to use the Internet, and as well, because of the fact that the copper wire is split at the exchange, you can even use your home phone while you’re also using the Internet, which is an incredibly useful factor.

There are a number of different options available to users with a broadband connection, whereby they can connect according to varied needs. Some people may ask if it is possible to connect two PCs to a broadband connection or if it’s possible to have more than two computers connected to the same broadband connection. The answer in short, is yes.

Where Can I Get Broadband?

Getting broadband access can be the difference between surfing the Internet the old way and engaging in its remarkable content the new way. It will change the way you surf the web and change the way you engage yourself, making the Internet a whole new playground to embark on wonderful journeys on. Broadband access is generally available from most Internet companies for a fee that differs depending on the value of the service and the connectivity options. Be sure to consult your local provider for more information.

What Is Broadband Cable?

Traditionally, computers communicate using baseband transmissions, which mean transmissions that only send one signal per wire. When your computer talks to your printer, it is using a baseband transmission. The same goes for your computer and your monitor. Broadband transmission allows one wire to carry many signals at the same time. Cable TV uses broadband technology and because of this, you can get your Internet access through the broadband cable without disrupting your viewing of cable channels.

What Does A Broadband Accelerator Do?

The primary purpose of a broadband accelerator is to sit between that of your broadband connection and your router, and most of these devices use DHCP, and consume an IP address which is generated by your router. Generally all you have to do here is leave it set to the auto-detect mode and let it run on its own without any sort of required assistance, and overall a broadband accelerator does have the same effect in reducing lag when playing over the Internet, until of course you begin to really saturate the network.

A broadband Internet service can change the way you look at your online capabilities. You can get faster download speeds and a more generous time of surfing thanks to the fast connections enabled with broadband Internet services. Some of the best service available online is available through a broadband Internet connection, so ensure that you remain on the cutting edge of technology today and grab hold of a broadband Internet service package before the deals run out.

Introduction to ADSL Broadband

2006-10-16T17:19:00.000-07:00

By James Dyson

Does ADSL mean for all of broadband and how does it actually work? If this is the thing you are looking for then you shall need to be more acquainted with ADSL.

ADSL (Asymmetric Digital Subscriber Line), a type of DSL, uses the existing copper-wired telephone networks for high-speed broadband internet. Using ADSL technology it is generally 10 - 140 times faster internet surfing than of standard 56k dial-up internet.

Difference between ADSL and SDSL SDSL is another kind of DSL, where the uploading speed is much faster than download speed. This technology of internet is widely preferred only by large business houses whereas ADSL is the choice of home users.

ADSL Speed This technology can run at up to 8Mbps speed and the most popular services in the UK are of 512Kbps speed. People also favor 2Mbps speed ADSL broadband and it mainly depends on their need of higher speed.

ADSL in UK A broad number of Internet Service Provides offer ADSL services in UK who actually resell the services obtained from network operators such as British Telecommunications (BT) and Kingston Communications. So if you need ADSL service you need these network operators in your place and around 90% of the UK is covered to have ADSL.

Availability of ADSL broadband This mostly depends on the telephone exchange near to you and your distance from it. Old exchanges are not suitable for ADSL and exchanges that are upgraded are only capable of transmitting ADSL signals, and so your local exchange should be an upgraded one.

Another important aspect for having an ADSL is the distance between your house and the exchange, which have significant effect on the ADSL speed. The distance away you are from the telephone exchange is the lesser in quality of the ADSL broadband. So, if you are long away from your exchange living in a rural area, it is better to favor 512 kbps broadband that does not have much impact of distance.

Billing in ADSL Broadband You can pay for your broadband service either monthly or yearly. You can choose the either that depends on your need and further plans. Most providers offer you the modem for free with the package if not you will need to rent it.

ADSL Installation In general, ADSL installations are so easy that you can install it by yourself and these services are available as self-install or plug and play. You need to connect your modem to your PC and to the sockets on the micro filter.

Installing the drivers and software provided with the modem are next and entering your username / password to login to broadband will be next final. Being a broadband user you will then sure have an extraordinary surfing experience over the internet.

You can find a cheap broadband ADSL provider in your area who provide fast broadband internet access by shopping around on the internet for best broadband deals. Most ADSL providers provide discounts to buy online.

A Review of Cable High Speed Internet Service

2006-10-07T00:39:00.000-07:00

By Morgan Hamilton

The computer certainly has seen its fair share of changes. Well, I guess I should actually say the PC and Mac. Regardless of what you prefer in computer finery, you are no doubt finding value now. Since the mid-nineties, many of us have gotten used to the idea of having a computer in our homes. We may have started with those dinosaur-looking desktop computers that came with space consuming towers and television size monitors, but they surely don't look like that anymore. The same case can be made for modern day Internet service. It's even hard to remember those dinosaur dial-ups. There is a new king and it is cable high speed Internet.

Which Internet service provider are you using? Are you a fan of DSL or cable high speed Internet? These choices are a recent phenomonom. There is a fierce battle for customers. For the consumer it is quite simple: who has the best deal? Cable high speed Internet is certainly the choice of most because it is the fastes and most reliable to date, but it can also be expensive. Being a subscriber of cable high speed Internet myself, I can tell you that I have pretty much tried them all. I began with Time-Warner, but hoped for something faster.

Then came Comcast after I relocated to a different state. I was satisfied with their service overall. More recently I relocated again. This is when I decided to give the local cable high speed Internet service a shot. To put it mildly, I was disappointed. I think it was the high prices that soured me. Paying more is no fun. Shortly after acquiring this new service, I decided to switch back to Time-Warner, which was cheaper and offered the same service.

For anyone still using dial-up, well, I feel your pain. Dial-up has certainly outlasted its usefulness. Why even bother with that horrific sound and turtle-like speed when you could be enjoying cable high speed Internet at a decent price? But then again, it is better than nothing. If you have the means then I suggest you try switching to cable high speed Internet. It isn't really all that expensive. I really can't put my stamp of approval on DSL Internet service either. Once again, it's rather slow. Do yourself a favor and check out cable high speed Internet. You'll be glad you did.

How Much Bandwidth is Required for VoIP Phones?

2006-09-30T08:22:00.000-07:00

By Chris Landry

A long-standing question for potential VoIP (Voice over Internet Protocol) consumers is “How much bandwidth does a VoIP phone require to make quality telephone calls?”

First of all, Bandwidth is defined as the ability to transfer data (such as a VoIP telephone call) from one point to another in a fixed amount of time. The higher the bandwidth speed you have, the more data you can send over your Broadband Internet connection.

There are two types of bandwidth at your location: upload bandwidth and download bandwidth. The Upload Bandwidth is the amount of data you can send to the Internet and download bandwidth is the amount of data you can receive from the Internet. The more Internet bandwidth you have from your ISP (Internet Service Provider) the better.

In most cases, the normal VoIP telephone call will use up 90 Kbps (kilobits per second). If you have a Broadband Internet service provider that doesn’t offer much bandwidth then most VoIP providers give you the option to lower the VoIP voice quality by lowering the bandwidth used for VoIP calls to 60 Kbps or, to really conserve your bandwidth, 30 Kbps. Most people can't tell the difference between the three settings. We suggest you use the high sound quality setting (90 Kpbs in most cases), if bandwidth is not an issue. High VoIP voice quality is generally the default setting but if you are running into a situation where your bandwidth is limited then you can adjust your VoIP bandwidth to one of the lower settings. Some consumers with 128 Kbps upload connections can receive less VoIP service quality due to a poor quality ISP (Internet Service Provider). By selecting a lower quality VoIP bandwidth setting, this problem can be avoided.

If you plan on using a VoIP service provider, should you get a DSL or a Cable Internet access provider? In general, DSL upload bandwidth starts at 128k where as Cable Internet upload bandwidth starts at around 600k. Cable Internet is a little bit more expensive, but it is also about 4-5 times faster than residential DSL and a bit friendlier to a VoIP telephone call. Having said that, both DSL and cable modem high-speed services provide sufficient broadband Internet access bandwidth to support any of the top VoIP service providers. If you are experiencing low Broadband Internet Service provider bandwidth, we suggest you try Packet8 VoIP. Packet8 VoIP boasts an advanced compression technology in which each active voice line uses approximately only 23Kbps of total data throughput, upstream and downstream.

The amount of bandwidth that a VoIP provider requires to make a quality telephone call is only one thing to consider when choosing a VoIP service provider. In fact, there are many things to consider when choosing a VoIP provider. An educated consumer generally results in a satisfied consumer.

How to Troubleshoot Your Internet Connection for DSL or Cable Service

2006-09-27T16:28:00.000-07:00

By George Chamoun

One of the common problems among internet users is testing their
internet connection to pinpoint the exact problem. There is a big number of internet users who use DSL, and cable modem service.

You set us your connection the way your ISP (internet service provider)instruct you to. Sometimes, it doesn't work for numerous reasons.

You service is not ready, your hardware in not connected properly, or your ISP is having problems.

Whatever the cause of the problem maybe, there are some diagnostic tools you can use in Windows XP, in order to identify the problem.

If you are not exact in your diagnostic, you will get a good idea at least.

Before we get to the diagnostic tools, let us discuss what is involved in an internet connection.

The information travels over the internet to your computer through your ISP service. This is done through a High speed modem then to a network card installed in your computer.

Your computer is called a host, your service provider will give
you the DNS IP address, and you get your login and password. That is all what you have from your ISP.

Sometimes, your internet connection fails, and you want to find
out the problem. You may be able to fix it, or at least get some
information about the problem to advise your isp for help.

You will start by accessing the command prompt by going in sequence to:

Start menu, program, accessories, then command prompt. A window
will open where you type commands from the prompt.

At the command prompt, you type: IPCONFIG. This command will give you the active network connection on your computer. Here is an example:

PPP adapter Copy :

Connection-specific DNS Suffix . :

IP Address. . . . . . . . . . . . : 68.239.158.45

Subnet Mask . . . . . . . . . . . : 255.255.255.255

Default Gateway . . . . . . . . . : 68.239.158.45

The above output was produced when I ran the Ipconfig command on my own computer running Window XP OS, and A DSL connection. The IP address is my computer address assigned by the ISP.

Please note, you can add an option to this command, in order to get more detailed information about your connection. Here is the output, when I ran the same command with the
"all" option.

Ipconfig /ALL

PPP adapter Copy :

Connection-specific DNS Suffix . :

Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface

Physical Address. . . . . . . . . : 00-53-45-00-00-00

Dhcp Enabled. . . . . . . . . . . : No

IP Address. . . . . . . . . . . . : 68.239.158.45

Subnet Mask . . . . . . . . . . . : 255.255.255.255

Default Gateway . . . . . . . . . : 68.239.158.45

DNS Servers . . . . . . . . . . . : 151.198.0.39
151.197.0.39
NetBIOS over TCP/IP. . . . . . . . : Disabled

Notice now, the output includes the phisycal address of the network interface card installed in my computer. Also, you see the DNS IP addresses. With the above information, I didn't have any problems.

Supposed ,I disconnect my DSL connection and ran the command again, this is the new result:

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :

IP Address. . . . . . . . . . . . : 192.168.0.1

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . :

Notice in this case, where I disconnected my connection, you don't get a DNS server. This tells you that I am not connected to the internet.

Also, notice the IP address starts with 192.168, which is the default address whenever your computer is not connected to the internet.

Another command is the ping command. It will allow to check if a computer is connected to the network and ready to communicate, whether intranet,
or internet.

Once you run it,it will sent a packet to the computer specified and gives the time it took for the packet to travel. This is an a output when I tried to ping www.yahoo.com:

C:>ping www.yahoo.com

Pinging www.yahoo.akadns.net [216.109.118.66] with 32 bytes of data:

Reply from 216.109.118.66: bytes=32 time=35ms TTL=55

Reply from 216.109.118.66: bytes=32 time=39ms TTL=55

Ping statistics for 216.109.118.66:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 35ms, Maximum = 39ms, Average = 38ms.

That shows that the host was reachable, and connected to the internet.

A very important command is the Nslookup. This will let you check if DNS (domain name server) is working properly. The function of the DNS server is to translate ip addresses to domain name of the networked computer. Here is an example:

C:> nslookup www.yahoo.com

Server: home5.bellatlantic.net

Address: 151.198.0.39

Non-authoritative answer:

Name: www.yahoo.akadns.net

Addresses: 216.109.118.67

Aliases: www.yahoo.com

So, you enter the name after Nslookup, it will give you IP addresses and vice versa.

In summary, there more commands in Windows Xp, but using the three above commands should give you a good idea about your internet connection problems. You can find where the problem is occurring. Is it your machine, or the ISP.

Thanks,

Kiss Dial Up Goodbye and Go Broadband

2006-09-25T15:37:00.000-07:00

By Gabriel J. Adams

Say, you aren't still accessing the Internet through an old fashioned dial-up service are you? If you are, you most certainly have our sympathies. So much so, that we'd like to introduce you to Broadband Internet.

Broadband Internet has been around for the last 7-10 years or so, and basically offers faster Internet access to web cam imagery, streaming video and audio, and everything else that you essentially wished you could access with a dial-up connection. Referred to as high speed internet, DSL, or cable modem, a broadband internet connection is four times faster than your current networking configuration, and the term "broadband" can be applied to any connection transferring at least 256 kilobits of data per second. No dial-up connection could ever match that speed regardless of how much you tweak your registry, or the number of times that you clear your cache!

Some people are resistant to new technology and declare that they'll stick to their archaic connection no matter what. "After all, I really only use my computer to download email," they say. This may be true, but if you're like most of us, you get email with attachments - attachments so large that they could take up to 3 or 4 hours to download with dial-up internet access.

With broadband Internet however, you can download hour-long video attachments within minutes, forward that video to a friend and download another one just like it large enough to fill an entire CD!

It would be easy to claim that videos aren't your interest and that they just aren't part of your everyday Internet itinerary. But with today's technology, more and more of us are formatting important information (like the local, national, and international news) in formats that demand additional power. Whether that format is a video, streaming audio, or a downloadable executable, you've got to be able to meet that demand with the proper equipment if you want stay informed within a reasonable amount of time.

One Of Many Broadband Options

2006-09-23T21:15:00.000-07:00

By Keith George

Aol broadband is the only provider that gives the choice of connecting to a high speed broadband package. The broadband connection is also available via cable modem. Home computers are connected to internet by a cable modem and in the process NTL´s cable network is used. Often one wonders if Aol broadband will affect the telephone service or not. The best thing about the connection is that one can be online and you can use the phone at the same time.

If you choose the Aol ADSL (asymmetric digital subscriber line) product the Aol broadband in a Box Package will contain special filters that plugs in the normal phone socket to allow one to use the phone and be online at the same time. If you choose the broadband cable product there is no need of using filter on the telephone line since the broadband connection is delivered via cable modem and not the telephone line.

To get Aol Broadband Gold one needs to have either a BT phone line or be the inhabitant of NTL broadband enabled area. The Aol broadband access is subjected to local availability and capacity levels and the landlord´s permission.

However there are certain requirements needed for the PC. Windows 98 Second Edition Windows, Windows 2000, at least a Pentium 233MHz processor, at least 64MB system memory, a spare USB port for Aol broadband Gold or a spare Ethernet port for Aol broadband Platinum. If there are certain services like ISDN home highway it is not possible to get this broadband service. For the Aol broadband cable product none of these restrictions are present.

If you install this broadband via an existing BT phone line there is no need of permission as long as phone line is in your name. NTL engineers installs the cable modem if you choose the broadband cable product. Then Aol broadband software is installed and one can start to enjoy the broadband features and benefits. No connection fee is needed for the modem or router. Payment is a monthly subscription fee due to access to Aol and internet via your broadband connection.

The Aol broadband Silver and Aol broadband Gold Box will contain a single broadband modem, three filters, CD that contains modem driver software plus your software, all cables that you need and certain easy step by step guide of how to install. Aol Platinum needs wireless contains router, three filters, a CD containing software, all cables that one needs and a guide of how to install.

Some DSL Broadband Definitions

2006-09-21T19:40:00.000-07:00

By Steve Cash

Often too many people get confused with all the definitions, here we have explained in easy to understand terms.

ADSL:

Asymmetric Digital Subscriber Line - asymmetric meaning it's faster downstream than upstream.

ASAM:

Advanced Services Access Manager -Whether you have a DSLAM or ASAM in your exchange doesn't really matter. They do the same thing. See DSLAM's as well.

ATM:

Asynchronous Transfer Mode - a method of encapsulation which is capable of many virtual circuits. With these, providers (ISP's) can split an ATM connection (155Mbit or 622Mbit) up into many connections. ATM isn't just used for DSL but in the case of DSL it's used to provision each customer.

Contention Ratios:

A contention ratio is the number of users to xMbit of bandwidth. For example some providers offer 2Mbit DSL, with a ratio of 50:1, meaning 50 users to 1Mbit of bandwidth.

CPE:

Customer Premises Equipment, the term that describes the equipment used on the customer end of a connection, for example your DSL modem/router or cable modem.

DSL:

Digital Subscriber Line.

DSLAM:

Digital Subscriber Line Access Multiplexer – They are placed in DSL enabled Telecomm exchanges, when your modem syncs up and the DSL light comes on, it means you are connected. When data travels down your connection, it goes from the CPE -> DSLAM -> RAN -> ISP

ERX:

Edge Routing Exchange. See RAN.

IPNet:

Telecommunications backhaul networks for carrying traffic from the customer to the ISP, i.e. carrying traffic from RAN's to ISP's.

Ping or Latency:

A ping measures the time in milliseconds that it takes for a packet to travel from your computer to a remote computer and back to you again. Just because you can't ping a given host, quite a lot of providers are beginning to filter ICMP (pings come under this protocol) traffic because it is commonly used to attack hosts and wastes a lot of bandwidth.
Many providers also give low priority to ping (ICMP) traffic which may mean your ping at a command line isn't very good, but in say a game, things may be fine.

RAN:

Regional Access Node These aggregates many DSLAM's connections and then feed the data to an ISP

RTT

Round Trip Time - the time it takes in milliseconds for a packet to go from A to B and back again. See ping.

SDSL

Symmetrical Digital Subscriber Line - symmetrical meaning the same speed up and down.

Units

There is a major difference between UPPER and lowercase

MB = MegaBytes

Mb = Megabits

kB = KiloBytes

kb = Kilobits

MB/s = MegaBytes per second

Mb/s = Megabits per second

kB/s = KiloBytes per second

kb/s = Kilobits per second

There is 8bits to a Byte, 8kb = 1kB

1Meg connections only transfer at 128kB/sec
or an 8Mb connection only transfers at 1024kB/sec or 1MB/s

What's The Difference Between DS3 And T3 Bandwidth?

2006-09-19T12:46:00.000-07:00

By Michael Lemm

Don't be confused about the difference between DS3 and T3 circuits. These terms are really synonymous. Instead you should focus on what they can do for you...and the best scenarios for application.

Digital Signal (DS) is a system of classifying digital circuits according to the rate and format of the signal (DS) and the equipment providing the signals (T). DS and T designations have come to be used synonymously so that DS1 implies T1, and DS3 implies T3.

A DS3 line (also known as a T-3) is an ultra high-speed connection capable of transmitting data at rates up to 45 Mbps. A DS3 line is equal to approximately 672 regular voice-grade telephone lines, which is fast enough to transmit full-motion, real-time video, and very large databases over a busy network. A DS3 line is typically installed as a major networking artery for large corporations and universities with high-volume network traffic. Other example applications include large call centers, enterprise wide VoIP and IP PBX systems, Internet service providers, research labs, video conference centers and software development companies. A DS3 is the second fastest, non optical connection offered in North America. A DS3 line is comprised of 28 T1 lines, each operating at total signaling rate of 1.544 Mbps.

DS3 circuits provide businesses and Internet Service Providers (ISPs) with up to 45 Mb/s of dedicated Internet connectivity. This is an ideal solution for users who have outgrown their T1 connections and are in search of unlimited, high-capacity access. A DS3 line actually consists of 672 individual channels, each of which supports 64 Kb/s. DS3 lines are extremely high bandwidth connections into a carrier's backbone. They typically include SLAs (Service Level Agreements) that guarantee uptime and performance.

The DS3 signal itself is composed of 28 DS1 signals and is constructed using a two-step multiplexing process. First, the 28 DS1 signals are multiplexed into seven DS2 signals. Second, the seven DS2 signals are multiplexed into one DS3 signal. Each multiplexing step uses bit stuffing to handle the different input frequencies. Overhead bits provide alignment, error checking, in-band communications, and bit stuffing control information.

Line rate: 44,736,000 b/s

Signals: 7 DS2 signals = 28 DS1 signals

Overhead bits:

56 bits total/frame

F-bits (framing) 28 bits/

M-bits (multiframing) 3 bits/

C-bits (stuffing) 21 bits

X-bits (message) 2 bits/

P-bits (parity) 2 bits/

Data bits between overhead bits 84

A DS3 connection is comprised up of two monthly charges: the local loop and the port charge. The local loop charge is the cost of the circuit provided by the Local Exchange Carrier (LEC) that allows DS3 access into the carrier's network. The loop charge is based on the distance from the customer's location to the edge of the carrier's network; the farther the customer is from the network, the more the loop will cost. Nearly every carrier prices loops differently so it is in your best interest to price DS3 service with several providers to ensure that you get the best deal.

DS Internet Access is the ideal solution for businesses that require high-bandwidth access at a reduced price. Whether you host high-traffic Web sites, support Web hosting or need high-capacity bandwidth on an as-needed basis, there's a level of DS3 service (Full or fractional) that will meet your needs. Fractional to full DS3 or T3 circuits run from speeds of 3 Mbps up to 45 Mbps.

For customers that require more bandwidth than a T1 line can provide but do not yet require the capacity of a full DS3 line, a fractional DS3 connection is the ideal solution. A fractional DS3 is similar to a full DS(T)3, only with some of the channels turned off. This reduces the total monthly cost and provides additional capacity that can be turned up in a matter of days. Unfortunately, the DS3 (T) loop is still required for this service.

If a full DS3 line is more bandwidth that you really need, it is also possible to get Fractional DS3, which gives you a portion of full DS3 bandwidth at a lower cost. Of course, DS3 is also available in multiples to increase bandwidth, similar to bonded T1 service.

DS3 service can be deployed for a wide verity of applications. The most common uses are DS3 point-to-point, DS3 internet, DS3 frame relay, DS3 voice and DS3 VPN. The pricing for these connections varies widely depending on the carrier, location of service and the application for which the connection is being used. Visit DS3 Bandwidth to obtain current "real time" rate quotes for your location.

DSL vs. T1: Which is Right For Your Business

2006-09-17T14:14:00.000-07:00

By Jeremy Maddock

When it comes to finding internet service for your small to mid sized businesses, the two most common technological possibilities are DSL and T1.

Digital Subscriber Line (or DSL) technology is an inexpensive form of high-speed internet connection frequently used by consumers and small to mid-sized enterprises. This type of connection allows data to be transmitted over the same copper wires used by telephones, at much faster rates than dialup, and can be used by up to 20 employees in a single location.

The drawbacks of DSL, however, include distance limitations, as well as the lack of a guarantee that service won’t lag when many other people in your area are online.

T1 connections, meanwhile, will give your office a set amount of bandwidth, which is then shared among your employees for their voice and data communication needs. T1 technology is seen as being somewhat more reliable than DSL, and can easily provide service to as many as 50 employees in the same office.

Overall, your decision between T1 and DSL will likely depend on the size of your office, and your level of reliance on internet technology, as well as service availability in your area.

DSL service is perfectly sufficient for the majority of small businesses, but those companies with more than 20 employees in a single location, and those who require guaranteed bandwidth levels at all time, may be better off to splurge on a T1 connection.

What Is VoIP and How Does It Work

2006-09-15T13:22:00.000-07:00

By Jason Morris

Introduction

The way we make phone calls is changing. In fact in many circumstances things have already changed. Take long distance calls for instance, many service providers are already using a technology called Voice Over IP or VOIP for short. If you have never heard of VOIP before, then the following article will change the way you think about how long distance phone calls are being made now, and about how all phone calls will be made in the future. Voice Over IP (VOIP) is a method for turning analogue audio signals into digital data that can be transferred over the internet.

You may be asking yourself how this is useful. Well think about it for a few seconds. If it is possible to turn analogue signals into digital data, then VOIP can turn a standard internet connection into a method for placing phone calls anywhere in the world virtually free, except for your internet service fee, enabling you to bypass the phone companies entirely.

Voice Over IP (VOIP) has the potential to completely revolutionise the way the worlds phone systems operate. There are many VOIP service providers that have been around for a while, and are growing steadily. Now the worlds leading telecommunications operators are waking up to the endless possibilities of this new technology, setting up VOIP calling centres around the world and promoting the sales of Voice Over IP phone systems.

Making a call

With VOIP phone systems it is possible to make a call in one of three ways:

ATA (gateway) – The simplest way to make a VOIP phone call is through the use of ATA’s (analogue telephone adaptor) sometimes called gateways. These devices enable you to make use of your existing standard analogue phones. You simply plug your standard handset into the ATA (gateway) then connect the ATA to your computer or your internet connection, enabling you to make VOIP calls. An ATA takes the analogue signal from your standard phone and turns it into a digital signal that ready for transmission over the internet. Some ATA’s (gateways) come with additional software that is loaded onto a host computer, enabling you to configure it for VOIP accurately.

IP Phones – These handsets look just like normal standard handsets. They have an RJ 45 Ethernet connector instead of the standard RJ 11 connectors. These phones have all the necessary software and hardware to handle VOIP calls already built in them. They connect directly to your router, providing a very fast and cost effective entry into the world of Voice Over IP.

Computer to computer – This is the easiest way to make use of the VOIP technology. There are many companies offering cost effective software that you can use for this type of VOIP. Usually the only charge you pay is the monthly one from your internet service provider, even for long distance calls. All you need is a microphone, speakers, a suitable sound card and a fast internet connection.

Chances are that you have already made a VOIP call without even realising it. The major phone companies already use VOIP to route thousands of long distance calls through a circuit switch and into an IP gateway. This is then received by a gateway at the other end and then routed to another local circuit switch. More and more companies are installing VOIP phone systems, and the technology will grow and grow until it finds its way into every business and household across the globe.

VoIP Features

Because with VOIP you can make calls from anywhere you have access to a broadband connection, users can take their IP phones or ATA’s with them on trips and still have access to what is essentially their home phone.

Some people use a softphone to access their VOIP service. A softphone is a specially developed software application that loads the VOIP service onto your desktop computer or laptop. Some even have an interface on the screen that looks like a traditional phone. These softphone applications allow you to place VOIP calls from your laptop; anywhere in the world you have access to a broadband connection.

Most traditional phone companies charge you for extra features that are added to your account. With VOIP service providers these usually come as standard. Features such as:

1. Caller ID

2. Call Waiting

3. Call Transfer

4. Repeat Dialling

5. Return Call

6. Three-Way Dialling

Some VOIP service providers also offer advanced call filtering features. These additional features allow you to decide how calls to a specific number are handled by using caller ID information. They allow you to:

1. Forward the call to a particular number

2. Send the call directly to voicemail

3. Give the caller a busy signal

4. Play a "not-in-service" message

Many VOIP services also allow you to check your voicemail over the internet or attach messages to an e-mail that is sent to your computer or PDA. It’s best to check with VOIP phone system suppliers and service operators exactly what features they offer as package and service prices vary greatly.

There are many other cost saving benefits that arise from a streamlined VOIP phone system network. For the network administrators, a VOIP phone system means they only have one network to maintain instead of two. The portability of the phone system is also greatly simplified. This is because most VOIP phone systems can be configured using a web interface, which can be managed by the network administrator. The MAC (move, add, change) process is made much easier, and you will not have to call your system/service provider for every MAC you carry out. All this means lower ongoing costs for your company.

Another cost saving for companies who implement a VOIP system is, because multiple offices, no matter where they are in the world are seamlessly connected, they can share many of the features VOIP can offer, such as:

1. One single receptionist

2. Auto attendant facilities

3. Voice mail system

Choosing a VOIP phone system

If you have decided that a VOIP phone system is the right step for your company, next you need to determine which of your existing telephone equipment you are able to keep. The potential cost savings that can be made through using any existing digital equipment are huge. Many digital phone systems can be IP enabled using minor hardware additions and software upgrades.

When shopping around for potential systems you need to be certain of the features they provide as standard and which are optional cost extras. You also need to be certain of exactly what is included with the system. Many suppliers claim to include everything you need, but standard components can vary from one company to the other. So you need to sure you are comparing equivalent systems when approaching potential suppliers.

You will also need to enquire about the compatibility of existing equipment. The technology used in many VOIP systems may affect the implementation of any existing telephone hardware.

You will also need to ensure that any devices such as fax machines, credit card processors, and security systems etc can be integrated into your new VOIP phone system. You should make any potential vendor aware of such devices so they can provide you with a suitable phone system for your requirements.

Finally, do not try to save money by buying used VOIP phone systems. Remember VOIP is a new technology, so even last years equipment is outdated. Also the installation cost will still apply whether the system is new or second hand, and the service costs may even be higher due to reliability issues. To put it simply it just isn’t worth the hassle, the higher secondary costs will wipe out any potential saving.

Cable Vs. DSL - Which is Better?

2006-09-13T18:05:00.000-07:00

By Mark Pascua

As broadband Internet becomes more mainstream, one of the most common questions we get is: which is better, cable or dsl?

DSL (Digital Subscriber Line)

Just like your existing dialup modem, DSL uses your existing copper wire phone line to deliver data at high speed. To qualify for DSL, you need the following:

- a phone line

- a DSL modem (which normally comes with the service)

- an Ethernet card or an available USB port ( most DSL modems allow both connections, but Ethernet is recommended).

- a phone company (ISP) that is offering DSL service (e.g., Verizon)

::Pros::

- Relatively cheaper than cable

- Dedicated line, so speeds are almost guaranteed

- You can talk on the phone at the same time while surfing the net

::Cons::

- Slower speeds compared to cable

- Speeds drop the farther away your home/office is from the central office

- Not available in all areas

Cable Internet

Cable Internet gets our recommendation. Cable, which you can probably already tell, uses the coaxial cable that your television uses. To qualify for cable internet, you need the following:

- a cable modem ( which normally comes with the service)

- an Ethernet card or an available USB port (most cable modems allow both connections, but Ethernet is recommended)

- a cable company offering cable Internet (e.g., Adelphia)

Speed wise, cable Internet typically ranges from 3 Mbps to 10 Mbps, up to 3-4 times faster than DSL. However, expect to pay more for the service - $40-$50 per month.

::Pros::

- Faster speeds than DSL

- More widespread than DSL

- Distance does not affect speed

::Cons::

- More expensive than DSL

- Line is shared with other users

Broadband - Is It All The Same?

2006-09-08T16:15:00.000-07:00

By Michael Russell

For the uninformed Internet surfer, broadband may very well be, well, broadband. After all, it's a generic term, so isn't all broadband the same? Or more specifically, aren't all broadband service providers the same? The answer to this question is unfortunately a very big no. And what makes this even worse is that because of the lack of knowledge that the general public has, they may simply go for the broadband service with the most attractive price tag. In many cases, this can leave you with a service that isn't much better than ordinary dial up. So what is it that makes broadband services different? While we can't go into great detail here, we'll at least try to give you some basics so you'll at least have some clue what to look for when shopping for a broadband service.

Broadband is loosely defined as a high-speed connection. What is a high-speed connection? It is generally accepted that anything above dial up, or 56K, is considered a high speed, or broadband connection. However, there are several types of broadband connections and they don't all provide the same speed, or data transfer rate. The most popular types of broadband are DSL, Cable, Wireless and Satellite. Each of these types delivers a different rate of speed, in spite of what the service providers claim and I am sure you've heard the claims. "4 times faster than DSL" and blah, blah, blah. The problem is, you have to read the fine print.

Fine print?

Oh yes and tons of it. The truth is, there are various levels of broadband and you pay based on the level you get.

The lowest level of broadband is basic broadband. These are actually very low speed broadband services that aren't very reliable and are pretty much good only for home use and not much better than dial up.

After that, you have what's called Business Grade Broadband. These are much higher speeds of around 512 Mbps. However, they can also be as low as 256 Mbps. These types of connections are more suitable for running a business and much more reliable than basic broadband.

The highest level of broadband is called Advanced Broadband. This level is used mostly by businesses that have an enormous number of users. This level is about as fast as you're going to get and offers the most reliable connections and security features. It is also very expensive.

It is because of all these differences that many casual users, such as the home users, don't know what to choose. Again, they get sucked in by the low price tags without reading the fine print that the service they are getting is the lowest level service. For example, one recent DSL ad offers a monthly price of about $20 a month for DSL service. But if you look at the fine print you will see that it is for their slowest speed.

It's like anything else in life. With broadband, you get what you pay for.

No, not all broadband is the same.
