Maintenance Commands and Trouble-Clearing Aids

test environment
This command performs hardware diagnostic tests of the environment monitoring
and control, and emergency transfer functions of both Processor Port Network
(PPN) cabinets and Expansion Port Network (EPN) cabinets. Circuit packs
involved are the Processor circuit pack (PPN simplex systems), the Duplication
Interface circuit pack (PPN duplex systems), and EPN Maintenance circuit packs.
The tone/clock circuit pack is involved in tests of the ring generator.
There are 8 Maintenance Objects involved in this testing:
1. DC-POWER tests power availability, battery charging and temperature
functions in SCC cabinets only.
2. EMG-XFER tests emergency transfer status
3. EXT-DEV tests external (AUDIX, for example) alarm status for both the
SCC and MCC cabinet systems.
4. POWER tests battery backup
5. AC-POWER tests AC power availability
6. CARR_POW tests carrier DC power availability. The long test of CARR_
POW includes a power recycle test for non-Processor Element (SPE)
carriers and is destructive. There is one instance of CARR_POW for each
carrier in the cabinet.
7. CABINET tests air flow and temperature
8. RING_GEN tests ringing voltage are tested in MCC cabinets only.
NOTE:
The processor carrier and its duplicate if present as well as any EPN control
carrier or an SCC carrier is not recycled. All port carriers are recycled, and
service is interrupted for each port carrier. If a carrier containing an active EI
is recycled, communications with that cabinet is disrupted. If a carrier
containing an active tone-clock board is recycled, all ports in the cabinet or
port network are service disrupted.
