Definition 1. - A type of high speed Internet connection that provides a great deal of bandwidth. Many businesses lease DS1 lines to connect to the Internet, but because they are expensive and offer more bandwidth than most small businesses and homes need, they are not realistic solutions for small and low-demand Internet users.

Definition 2. - Digital Service rate 1. The combined transmission rate (1.544 Mbps) of all 24 circuits in a DS1 connections. A Aberdeen DS1 line is typically used by small and medium-sized companies with heavy network traffic. It is large enough to send and receive very large text files, graphics, sounds, and databases instantaneously, and is the fastest speed commonly used to connect networks to the Internet. Sometimes referred to as a leased line, a DS1 is basically too large and too expensive for individual home use.

Definition 3. - The T-carrier system, introduced by the Bell system in the US in the 1960's, was the first successful system that supported digitalised voice transmission. The original transmission rate (1.544 Mbps) in the Aberdeen DS1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Definition 4. - The DS1 (or T-1) carrier is the most commonly used digital line in the United States, Canada, and Japan. In these countries, it carries 24 pulse code modulation (PCM) signals using time-division multiplexing (TDM) at an overall rate of 1.544 million bits per second (Mbps). DS1 lines use copper wire and span distances within and between major metropolitan areas. A DS1 Outstate System has been developed for longer distances between cities.

The t1 internet service has been around for over 40 years but never have there been so many "flavors" available. The number of providers has jumped since deregulation in 1996 from a few dozen to several thousand. As the telecom shakedown that began in 2001 continues many of these comapnies are trying to stay afloat by capturing as many customers as possible with inexpensive products they claim to be T1. Don't be fooled!

Many of the desperate companies are putting together inferior products they claim are T1 products. Be leary of products with the funny titles like "burstable" and "reach". These products are oversubscribed much like a DSL product. This means the provider put's a singled T1 connnection in a CO (Central Office) and sells T1 connections to 3 or 4 customers hoping they don't all use the service at the same time. True T1 access means dedicated access to the internet and you always have access to 1.54Mbps.

Make sure your T1 product is a "clearchannel" product and is not shared with other users. Also be sure you have an SLA or Service Level Agreement from your provider. A SLA will specify the access you will receive and the penaly the service provider will pay if they do not provide such service. If you need help establishing the proper SLA seek the help of a professional if you don't have one in house. It's much better to pay a small fee up front than to enter a long term contract with an inferior carrier. You can also get professional assistance free of charge by simply contacting one fo the many T1 brokers on the internet.

While Dave Letterman may never read this list on his show, we've created a Top 10 list of California T1 Internet Providers. In our review of service providers we considered realiabiltiy, customer support, provisioning and financial stability. In our opinion a top provider of services will have a high rating in each of the catagories. Unfortunately some of the providers we found were regional providers and may not be near you but two of them are so good you may just want to move closer to be on their network!

The top company in our survey was Telepacific. The only downside to this company is the fact that they only offer service in California and Las Vegas. Telepacific received top marks in all four or our categories and is what we recommend most to customers in California. The second carrier in our list was USLEC. Like our fist pick USLEC is a regional player offering services in the south and on the eastern seaboard. USLEC was founded and is run by engineers. These people have a passion for getting it right and keeping their customers happy. Number three on our list is New Edge Networks. New Edge is a national player found predominantly in metro areas. New Edge is large enough to be a strong player but still small enough to treat customers like a small company.

Our number four position goes to Netifice, formerly Epoch. Again, a small Tier 1 player but excellent service nationwide. Number five position goesto ACC Business. Available everywhere in the continental US, ACC used the ATT network exclusively and provides a high level of service. Positions six through ten when in the following order: Telarus, Sprint, Xspedius, PNG, and Megapath. When looking for a reliable provider you should be comfortable with any of these. Make sure you speak to your broker about the strengths and weaknesses of each carrier. While our rankings were based evenly on the four criteria mentioned at the beginning of the article you may decide that some criteria are more important to you than others. Good luck in your search.
