Nortel Networks 114200-E manual Connecting to the Isdn Interface, Connecting the Isdn BRI Cable

Installing the ARN

Serial adapter modules, labeled COM, can be in position 1 or 2. These interfaces are COM1 and COM2.

3.Secure the cable to the interface using the capture screws on the cable.

4.Connect the remote end of each cable to the appropriate communications equipment.

Connecting to the ISDN Interface

You connect ISDN service to the connector on an installed ISDN BRI U or ISDN BRI S/T adapter module. Modules with an S/T interface provide dialup connection to the ISDN network through a terminal adapter. Modules with a U interface allow you to connect directly to the ISDN network switch.

The BRI provides two B channels, and supports full D-channel signaling and call setup/teardown as defined in 1988 CCITT (now ITU-T) Recommendation Q.921 and Q.931. For more information, refer to Configuring Dial Services.

To connect ISDN BRI services:

1.Insert the ISDN cable into the ISDN BRI S/T or U interface (Figure 1-13).
