Circuit Packs
All circuit pack slots in the Compact Modular Cabinet (CMC1) are “universal
slots.” Any slot can contain any type of circuit pack (port, control, or service), so
there is no purple and white slot coding that is found on other Avaya Definity
Server products.
The requirements for slot allocation are:
■
The TN2402/TN798 Processor must be installed in slot 1
■
The TN2182 Tone-Clock must be installed in slot 2
NOTE:
The TN2182 is the only Tone-Clock circuit pack allowed in the CMC1.
■
A TN744D Call Classifier/Tone Detector circuit pack may be required in
systems with heavy traffic. This circuit pack can be installed into any port,
but slot 1 of Cabinet B is recommended.
Maintenance Objects
The maintenance subsystem 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. Although 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. 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 log
screens and as output of various commands such as test board, busy tdm-bus.
