Packet Interface Test (#598)
This test is non-destructive 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
duplicate 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 Packet Bus in the specified port
network has a minor alarm active, is out of service, or if the Packet Bus in the PPN
is out of service. This test runs as a part of initialization, periodic, scheduled,
error analysis, and demand test sequences. Figure 9-5
shows a schematic of the
test.
Figure 9-5. Packet Interface Test (#598)
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.
