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
background maintenance tests in the system are divided into three groups:
■
Periodic tests are usually performed hourly by maintenance software.
These tests are nondestructive and can be run during high-traffic periods
without interfering with calls.
■
Scheduled tests are usually performed daily and are generally more
thorough than periodic testing. These tests are considered destructive and
are run only during off-hours to avoid service disruptions.
■
Fixed interval tests are performed at regular time intervals that 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. Using the management
terminal, maintenance personnel can “demand” the same tests that the system
initiates in periodic or background testing. Demand tests include periodic tests
plus other tests required only when trouble occurs. Some nonperiodic demand
tests are destructive (service-disrupting) tests, and are identified in boldface type.
