Maintenance Testing
Most troubles are reduced to the circuit pack level and can be identified by LEDs
on the circuit packs and software reports generated by the system. The
maintenance tests in the system are divided into three groups:
■
Periodic
Background tests are performed by software maintenance, usually on an
hourly basis. These tests are nondestructive and can be run during high
traffic periods without interfering with calls.
■
Scheduled
Background tests performed by software maintenance, usually on a daily
basis, are generally more thorough than periodic testing. The tests are
considered destructive and are run only during off-hours so as not to
interfere with calls.
■
Fixed interval
Background tests performed by software maintenance at regular time
intervals (these intervals cannot be administered). These tests run
concurrently with periodic maintenance. The following table lists the MOs
that run fixed interval testing.
Demand tests are also run by the system when it detects a need or by
maintenance personnel in trouble-clearing activities. Demand tests include
periodic tests plus other tests required only when trouble occurs. Some
nonperiodic demand tests may disrupt system operation. In this book, destructive
(service-disrupting) tests are identified in boldface type.
Maintenance personnel can use the management terminal to initiate the same
tests that the system initiates. The terminal screen displays the test results.
