Overview

T1 is a mature technology originally developed for voice telephone transmission. It was used to aggregate a number of voice lines into a single connection to the telephone network. Today T1 is also widely used to transmit digital data using widely available equipment and established wiring commonly available in diverse locations.

Configuring T1 Physical link

There are a number of parameters that can be configured for a T1 link. If you have control of both sides of the link, then the default configuration is probably the best choice. If you must connect to a line controlled by another organization, you will need to configure the line to correspond with the settings at the other end. You can specify the following parameters:
