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.
