ISDN Primary Rate is a communications service that allows the system to make up to 23
connections over a single line. It uses a 4-wire T1 line that carries 24 channels, each providing 64000

between two systems. The 24th channel is used for signaling information (the data link).
The customer should request the following options for a Primary Rate Line that is connected
