The BRI blade provides:
Two (GCD-2BRIA) 2-Channel Circuits (2B + D) configured as T-Bus

64Kb/s Clear B-Channel and 16Kb/s D-Channel

Two Status LEDs

Connector for GPZ-2BRIA

These trunk circuits can be connected to either ISDN trunks or ISDN
telephones, depending on the switch setting in 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 NTI Network Termination.
To block new calls on the blade, system programming must be used. This
program prevents new calls from being established on the blade, but it does
not terminate any existing call.
With the maximum number of blades installed, the following can be
provided:
The 2BRI provides 30 BRI circuits and 60 BRI channels.
