2500 ABORT An internal operation failed; the test could not be completed.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1 FAIL The test did not detect the test tone through the loop around connection.
NOTE:
If the circuit pack is a TN570, the packet portion of this test was not
run since the circuit portion failed.
1. Test the Active Tone-Clock on the Port Network that contains the
defective Expansion Interface circuit pack to verify that dial tone is
being supplied.
2. If the Tone-Clock is healthy, issue the test board PCSS long
command on the Expansion Interface circuit pack.
3. If this test continues to fail, replace the Expansion Interface circuit
pack or transceiver. Then, reissue the test board PCSS long
command on the new Expansion Interface circuit pack.
2 FAIL The test tone was transmitted and detected correctly, but the correct data
packet was not detected by the TN778 Packet Control circuit pack. This
error only applies to the TN570 Expansion Interface circuit pack.
1. Test the TN778 Packet Control circuit pack to verify that it is
functioning properly. If any tests fail, investigate those tests and repair
the Packet Control circuit pack.
2. If the Packet Control circuit pack checks out OK, issue the test board
PCSS long command on the Expansion Interface circuit pack.
3. If Test #242 continues to fail, replace the Expansion Interface circuit
pack. Then, issue the test board PCSS long command on the new
Expansion Interface circuit pack.
4. If Test #242 continues to fail, replace the lightwave transceiver, reset
the circuit pack and issue the test board PCSS long command on the
Expansion Interface circuit pack.
