Installing the ARN/DC
116273-B Rev 00
1-15
Connecting to the ISDN Interface
You can connect an ISDN cable to any ARN/DC that contains an ISDN BRI
adapter module.
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.
Connect the ISDN cable to the ISDN BRI S/T or U interface
(Figure 1-10
).
Modules with an S/T interface provide connection to the ISDN network
through a terminal adapter. Modules with a U interface allow you to connect
directly to the ISDN network switch.
Figure 1-10. Connecting the ISDN BRI Cable
2.
Connect the other end of the cable to the ISDN communications
equipment.
