Chapter 5: Communication Manager
Maintenance-Object Repair
Procedures
Note:
Note: This chapter does not contain MOs for the DEFINITY Wireless Business System
(DWBS), nor MOs for messaging systems. Refer to the maintenance
documentation that accompanies these products for this information
The Communication Manager maintenance subsystem is partitioned into separate entities
called Maintenance Objects (MOs). A maintenance object can be:
● An individual circuit pack or media module
● A hardware component that is part of a circuit pack or media module
● An entire subsystem
● A set of monitors
● A process (or set of processes)
● A combination of processes and hardware
“Maintenance names” are recorded in the Error and Alarm logs. Individual copies of an MO are
assigned an address that defines the MO physical location in the system when applicable.
These locations display as the port field in the Alarm and Error logs and as output of commands
such as test board (see Figure 21: Display of test board
on page 326).
