Packet Interface Test (#598)
This test is non-destructive and attempts to send a data packet from the TN1655
Packet Interface circuit p ack through any ATM PNC Expansion Interface circuit
packs. The path the data p acket takes depend s on the location of the ATM-PNC
Expansion Interface circu it pack being tested and whether the system has
duplicate Port Network Connec tivity.
The Packet Interface Looparound test c hecks the Packet Bus interface c ircuitry
on this board. The on-board LANHO c hip sends a data stream to the bus,
retrieves it back, and chec ks for its consistency. If the data is consistent, the test
passes; otherwise, it fails. The test aborts if the Pack et Bus in the specified p ort
network has a minor alarm active, is out of servic e, or if the Packet Bus in the PPN
is out of service. This test runs as a part of initial ization, periodic, sch eduled,
error analysis, and demand test se quences. Fig ure 9- 5 shows a schematic of the
test.

0 NO BOARD No board was detected by the test.
1. Resolve any wrong board (Error 125) or no board (Error 131)
issues.
2. Check that the board is properly translated and inserted. If so,
check for hyperactivity (Error 1538). If hyperactive, use the reset
board UUCSS command.
3. Run the test again. If it fails, the NCE chip on board may be bad.
Replace the board and retest.
