Maintenance Objects
The system is partitioned into separate entities called Maintenance Objects
(MOs). Each MO is referred to by an upper-case, mnemonic-like name that serves
as an abbreviation for the MO. For example, “CO-TRK” stands for “Central Office
TRunK”. Each MO is monitored by the system and has its own maintenance
strategy. Most MOs are individual circuit packs. Some MOs are hardware
components that reside on part of a circuit pack. For example, the TDM bus Clock
circuits reside on the Tone/Clock circuit pack. Other MOs, such as cabinet
environmental sensors, represent larger subsystems or sets of monitors. Finally,
some MOs, such as SYNChronization, represent processes or 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’s physical location in the
system. These locations appear in the “PORT” field in the alarm and error logs
and as output of various commands such as test board and busy tdm-bus.
