Circuit Pack Descriptions

7-94 Issue 8.0 July 2002

The OC48 RCVR A/D circuit pack monitors the two −48 volt sources to the circuit

pack and any failures are reported to the board controller. If the OC48 RCVR A/D

circuit pack detects a failure of the onboard fuse or power converter, the red

FAULT LED will light. If the fuse or +5 volt power converter fails, the LNCTL circuit

pack provides +5 volts to light the FAULT LED on the OC48 RCVR A/D circuit

pack.
