BRI (2BRIDB) Daughter Board
The BRI daughter board provides 2 BRI circuits. This daughter board is installed on the 2BRIU or 082U blade
and provides:
2 (2BRIU) 2-Channel Circuits (2B + D) configured as T-Bus or S-Bus
●
64 Kb/s Clear B-Channel and 16 Kb/s D-Channel
●
Connection point for 2BRIU or 082U
●
These trunk circuits can be connected to ISDN trunks or ISDN telephones, depending on the switch setting
within system programming. All ISDN telephone circuits (#1-2 [BRI blade] and #3-4 [with the BRI daughter
board]) are supplied DC power from the UX5000 system.
In order to block new calls on the blade, system programming (Program 90-05-01, Menu 3) must be used. This
program will prevent new calls from being established on the blade, but it will not terminate any existing calls.
