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

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?

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

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

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.
