Connectivity - T1 Internet Services Using ATM

ATM is another (new) technology that was designed to get better utilization of a circuit in certain situations. It accomplishes this by enabling a single circuit to carry different types of traffic. The goal of ATM is similar to that of Frame Relay, but ATM tries to accomplish a little more, and uses a different approach than Frame Relay.

Like Frame Relay, ATM allows customers to share a single circuit. ATM also supports a concept called Quality of Service (QoS) which allows for finer control of information transfer than Frame Relay. But this incurs some data transmission overhead.

Also like Frame Relay, ATM enables the user to have some amount of capacity dedicated to them, while sharing the rest of the capacity of the circuit. This means that if somebody is not using their share, then you might be able to use their part. The amount of capacity that is dedicated to the user is called the Specified Bit Rate (or SBR). The capacity available beyond the SBR is called the burst rate.

A T1 circuit consists of 2 components for recurring charges:

  • local loop
  • Internet port

The local loop is a telco supplied wire that is the T1. The Internet port is the connection of that wire to the Internet. When pricing T1 based services, it is important to understand what is included in the pricing and what is not (so you can compare "apples to apples").

For an ATM circuit, the telco supplies the T1, and supplies the Internet port. The prices we listing in this page are ballpark prices based on averages. Our prices include only our setup and Internet port charges. The cost of the T1 local loop will come from the local telephone company.
