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.
