PROCR (Processor Circuit Pack)
NOTE:
For systems with a TN2404/TN790 RISC Processor circuit pack see
maintenance object
‘‘PROCR (TN2404/TN790 RISC Processor Circuit
Pack)’’ .
NOTE:
Alarms on the MEM-BD [386 systems only], PROCR and PR-MAINT
maintenance objects (MOs) are indicated by the red LED on the Processor
circuit pack.
The TN786B has an 80386 processor that uses on-board flash ROM and DRAM
memory. The TN786B Processor circuit pack is comprised of the 80386
Processor (PROCR), the MainTenance Processor (PR-MAINT) and Memory
(MEM-BD).
The TN786B Processor circuit pack is responsible for the execution of the
DEFINITY software. This includes all of the call processing, maintenance, and
administration functions. The Processor circuit pack is the most critical component
to proper operation of the system.
The PR-MAINT is responsible for monitoring the sanity of the Processor circuit
pack as well as the environmental conditions. The PR-MAINT provides the serial
interfaces for the administration terminal and for the Call Detail Recording (CDR)
ports. The PR-MAINT also provides the communications interface to INADS for
alarm reporting and remote maintenance capability.
In High and Critical Reliability systems, the PR-MAINT is part of the
communications path between the Active Processor Element and the Standby
Processor Element.
