These trunk circuits can be connected to either ISDN trunks or ISDN
telephones, depending on the switch setting within system programming.
All ISDN telephone circuits (#1-2 and #3-4 with the BRI daughter board)
are supplied DC power from the system.
The BRI Interface blade uses a single universal slot. Each blade connects
to the network via an NT1 Network Termination.
In order to block new calls on the blade, system programming must be
used. This program will prevent new calls from being established on the
blade, but it will not terminate any existing calls.
With the maximum number of blades installed, the following can be
provided:
The CD-2BRIA provides 92 BRI circuits and 184 BRI channels.

Installation
To install the CD-2BRIA:
1. Plug the CD-2BRIA blade into the system chassis.
2. Before proceeding to Step 3, wait to verify that the STATUS LED starts
to flash. (Refer to Figure 4-22 CD-2BRIA Blade on page 4-63
location of the LEDs on the blade.)
With normal operation, the status LED flashes fast. If
trouble was found during the self diagnostics routine,
the status LED flashes slow.
Once connected, the PKG LED will not be indicated for
the status of Layer 1 Link.
3. Connect the cable from the NT1 Network Termination cable to the CN7
or CN8 connector on the CD-2BRIA blade and/or PZ-2BRIA daughter
board. (Refer to Figure 4-22 CD-2BRIA Blade on page 4-63
location of the connectors on the blade.)
