RLCM alarm clearing procedures

Alarm display

At the MAP subsystem display, the LCM alarm appears under the PM

header. This alarm indicates an alarm condition in the RLCM. The n

indicates the number of RLCMs with alarms. The *C* that appears under

the alarm indicates the alarm class is critical.

Use this procedure to recover service in an RLCM when both units of the

line concentrating module (LCM) are out of service. This condition always

produces a central side busy (CBsy) alarm.

The LCM is system busy (SysB) or C-side busy (CBsy). An LCM is SysB if

both units are SysB or if one unit is SysB and the other unit is manual busy

(ManB). An LCM is CBsy when both units of the LCM are CBsy.

When an LCM is SysB or CBsy, call processing ceases. This condition

results in a critical alarm indication.
