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).
Figure 1-13. Connecting the ISDN BRI Cable
2.
Connect the other end of the cable to the ISDN communications device.
