T1 Internet Access for Dummies
This particular T1 Internet Service continues to be around for more than 40 years yet never have there been so many "flavors" available. The number of providers has jumped from deregulation in 1996 from a few dozen to several thousand. Since the telecom shakedown that began in 2001 continues many of these companies are trying to stay afloat by capturing as many customers as possible with inexpensive products they claim being T1. Don't be fooled!
Many of the desperate businesses are putting together inferior solutions they claim are T1 products. Just be wary of products using the weird titles such as "burstable" as well as "reach". These products can be oversubscribed similar to a DSL product. This suggests the provider places a single T1 link in a CO (Central Office) and provides T1 connections to three or four customers banking on the fact that they don't all use the resource 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 in Van is really a "clearchannel" product and is not shared with other users. Also be certain you truly have a powerful SLA or Service Level Agreement from your supplier. A SLA will specify the access you will get and the expense the service provider will pay on condition that they don't supply such service. If you need assistance, establishing the correct SLA gives you the help of an expert if you don't have one in house. It's much better to spend a small price up front than to enter a long term contract with an inferior carrier. You can also get professional assistance gratis by just contacting one of the many T1 brokers on the Internet.
