PDATA Port Local Loop-Around Test (#602)
This test is destructive.
This test verifies the per port circuitr y on the PDATA circuit p ack. This test is
executed by the PDATA circuit pack on c ommand by the switc h. The loop-back is
done internal to the circu it pack at point "A" in the figure. Failure of this test
indicates an on-board fault associated with the port hard ware on the circuit pac k.

1 FAIL Response to the test was not received for the PDATA circuit pack within the
allowable time period.
1. Retry the command at 1-minute intervals a maximum of 3 times.
2. Reset board UUCSS if the other ports on the board are not in use (Yellow
LED is off or run status data-module extension).
3. Retry the command at 1-minute intervals a maximum of 3 times.
4. Replace the circuit pack.
2 FAIL The received test packet from the PDATA port is different than the test packet
transmitted to it.
1. If the test fails 3 times, reset board UUCSS if the other ports on the board
are not in use (yellow LED is off or run status data-module extension).
2. If the test continues to fail, replace the circuit pack.
PASS The PDATA port is able to terminate a LAPD link.
