Link Quality Test (#233)
This test queries the TN765 circuit pack for the latest error rates (number/minute)
for certain counters that are kept by the TN765. The test passes if all the error
rates are below a certain threshold. The counters that are queried are the Level 2
Reset SABM(E) [Set Asynchronous Balanced Mode (Extended)] counter, the
Level 2 I-frame Retransmission counter, and the invalid LAPD frame counter.
12 FAIL PI-BD reported that Loop Around Test failed.
1. Retry the test.
2. If Test #182 fails, see section for Test #182 first.
3. If Test #182 passes and Test #183 continues to fail, replace either the
TN754 or TN784 Digital Line or the TN722 or TN767 DS1 Interface
circuit pack.
4. If Test #183 still fails, replace the TN765 PI-BD.
PASS The loop around from the TN765 PI-BD to the Digital Line or DS1 Interface
circuit pack and then back to the PI-BD passed.
