Description
This daughter board provides two BRI circuits and is installed on the
CD-2BRIA blade. This board provides:
♦
Two 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 CD-2BRIA or CD-LTA
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 (CD-2BRIA blade) and #3-4 (with the PZ-2BRIA
daughter board)] are supplied DC power from the UNIVERGE SV8100
systems.
System programming must be used to block new calls on the blade. This
program will prevent new calls from being established on the blade, but it
will not terminate any existing calls.
