Description 0
Alarms provide either a visible or audible indication when the system detects a
problem that needs immediate attention.
■ Alarm Button. A programmed button on Direct-Line Consoles (DLCs) and
a factory-set button on QCCs that alerts an operator to system problems.
The red LED next to the Alarm button on the operator console lights when
the system detects a problem (such as a problem with one of the
lines/trunks or some other system error) that requires immediate attention.
It remains on until the problem is corrected.
■ Maintenance Alert. An alert device such as a bell or strobe light
connected to the line or trunk designated as a maintenance alarm jack. The
device rings or lights when the system detects a problem.
The red LED on the processor module turns on when the system detects a
problem that requires immediate attention. It remains lit until the problem is
corrected.
The red LED on some modules turns on when the system detects a
module-related problem, for example, a loss of service on a 100D module.
Considerations and Constraints 0
As soon as the system detects a problem, the red LED next to the Alarm button
turns on and/or the maintenance alert sounds or flashes.
All system operator consoles with an Alarm button receive the indication.
