Maintenance

Maintenance diagnostic programs are provided by the software to control and
test the Message Center services. Message Waiting lamps and set indicators
on Meridian products can be tested on a system basis. For a complete
description of the overlay programs involved, and their operation, please refer
to the X11 Software input/output guide.
LD 32—Network/Peripheral Equipment Replacement Diagnostic
This diagnostic can be used to test the neon Message Waiting lamp on 500
and 2500 telephones. It can also be used to print out a list of any defective
lamps. The telephones with Message Waiting key/lamp pairs are not included
in this test.
LD 61—Message Waiting Lamp Reset (MWL)
This program can be set to run automatically as part of the Midnight Routines
(MIDS) or can be run manually from a peripheral input device. LD 61 is used
to reset the lamp and status for all telephones within the system. When run
manually, the command G starts the program.
The program does not reset lamp status unless all Message Center telephones
are out of service, as under Night Service conditions.
