Packet Interface Test (#598)
This test is nondestructive and attempts to send a data packet from the TN1655
Packet Interface circuit pack through any ATM PNC Expansion Interface circuit
packs. The path the data packet takes depends on the location of the ATM PNC
Expansion Interface circuit pack being tested and whether the system has
duplicated port-network connectivity.
The Packet Interface Looparound test checks the packet-bus interface circuitry on
this board. The on-board LANHO chip sends a data stream to the bus, retrieves it
back, and checks for its consistency. If the data is consistent, the test passes;
otherwise, it fails. The test aborts if the specified EPN’s packet bus has an active
minor alarm or is out of service. This test runs as a part of initialization, periodic or
scheduled error analysis, and demand-test sequences.
