Maintenance Objects

Maintenance Objects
The system is partitioned into separate entities called maintenance objects (MOs).
Each MO is monitored by the system and has its own maintenance strategy. Most
MOs are individual circuit packs such as the:
Direct Inward Dial Trunk circuit pack (DID-BD)
DS1 Tie Trunk circuit pack (TIE-DS1)
Expansion Interface (EI) circuit pack (EXP-INTF)
Some MOs represent hardware components that correside on a circuit pack. For
example, the following circuit packs have the listed circuits residing on them:
IP Server Interface circuit pack (IP-SVR) — Packet Interface (PKT-INT), IP
Server Control (IPSV-CTL), Enhanced Tone Receiver (ETR-PT), TDM bus
clock (TDM-CLK), Tone Generator (TONE-PT), and Tone-Clock
(TONE-BD)
Tone-Clock circuit pack (TONE-BD) (found in non-IPSI-connected port
networks only) — TDM bus clock (TDM-CLK) and Tone Generator
(TONE-PT).
Other MOs represent larger subsystems or sets of monitors, such as an
expansion port network (EXP-PN) or a cabinet's environmental sensors
(CABINET).
Finally, some MOs represent processes or combinations of processes and
hardware, such as synchronization (SYNC) and duplicated port network
connectivity (PNC-DUP). The previous abbreviations are maintenance names as
recorded in the error and alarm logs. Individual copies of a given MO are further
distinguished with an address that defines its physical location in the system.
These addresses are described in
instructions and a description of each MO appear alphabetically in
