PROCR (TN2404/TN790 RISC
Processor Circuit Pack)
NOTE:
For systems with the TN786B Processor circuit pack, see maintenance
object,
‘‘PROCR (Processor Circuit Pack)’’ .
NOTE:
Alarms on the PR-MEM, PROCR and PR-MAINT maintenance objects
(MOs) are indicated by the red LED on the Processor circuit pack.
This section applies to the TN2404/TN790. The TN2404/TN790 has a RISC
processor (PROCR) that uses on-board Flash ROM and DRAM memory
(PR-MEM). This circuit pack also contains the MainTenance Processor
(PR-MAINT).
The RISC Processor circuit pack portion is responsible for the execution of the
DEFINITY Generic 3 software package. This includes all of the call processing,
maintenance, and administration functions. The RISC Processor circuit pack is
the most critical component to the correct operation of the system.
The PR-MAINT (MainTenance Processor for RISC systems) is responsible for
monitoring the sanity of the RISC Processor circuit pack and the environmental
conditions. The PR-MAINT provides the serial interfaces for the SAT and for the
Digital Communications Equipment (DCE) 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.
