BIP alarm connector
The BIP alarm connector is the bottom connector in the alarm/BITS module.
It performs the following functions:
• BIP alarm termination, which provides proper over-voltage protection
for all BIP alarms and provides an interface between the BIP and the CP
and CPX slots through the backplane
• shelf ID termination, which provides proper over-voltage protection and
a backplane interface for shelf ID and the BIP signals to the CP and CPX
slots
• audio/visual alarm termination, which provides a connection between the
backplane audio/visual alarm signals and the BIP interface to the CP and
CPX slots
The location of the BIP alarm connector is shown in the figure "Faceplate of
an alarm/BITS module in a Passport 15000" (page 117).
The pin assignments for the BIP alarm connector are shown in the table "BIP
alarm connector pin-out" (page 121).
