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.
