About this Book
Chapter 9, ''Packet Bus Fault Isolation and Correction''
Packet Bus maintenance and the interactions of the bus with Packet circuit
packs. The chapter also discusses how Packet Bus faults are isolated and
corrected.
Chapter 10, ''Maintenance Object Repair Procedures''
troubleshooting and repair instructions for every component in the system.
The chapter contains repair procedures for system-alarmed and user-
reported troubles. For each MO, a table lists the alarm level, hardware
error associated with the MO, and the associated test that caused the error.
The test sequences and the specific command line entry required to run
the tests are given and a brief description of each test. Explanations of
error codes associated with each test are given, as are specific
maintenance procedures to be used to resolve each problem.
Each MO is described in a separate section of
Repair Procedures''. The individual sections are labeled with the name of the MO
exactly as the name appears in the Alarm Log; for example, MAINT (for
Maintenance circuit pack). The only exception is the MO name for Common Port
Circuit Pack maintenance which is XXX-BD. The XXX-BD section contains a set
of common tests used by certain circuit packs listed in the section. The common
portion of these circuit packs is the generic hardware that interfaces with the Time
Division Multiplex (TDM) Bus.
