BRI configuration process map
The following process map shows the steps for configuring loops for T-1 based BRI modules.
Figure 62 Process map: Configuring the loops for your BRI module
You can program a loop to support either trunking services to the ISDN network, or terminal
services to one or more ISDN devices. The following sections describe the programming for each
type of loop. For complete module installation instructions and safety precautions, see the
Installation and Maintenance Guide .
Using an NT-1 for BRI U2/BRI U4
The Business Communications Manager supports the BRI S/T protocol. If your ISDN service
provider provides U-type ISDN service or the BRI devices are U-type devices, you need to obtain
a network terminal (NT-1) device. This device is installed between the ISDN network feed and the
Business Communications Manager for trunking loops. It is installed between the Business
Communications Manager and the ISDN device or the ISDN bus connecting several ISDN devices
on a BRI terminal loop.
Note the loops that are active. (Services, Telephony Services, Loops)
Configure loops to support ISDN trunks or ISDN terminals.
