PI-LINK (Processor Interface Link)
Issue 4 May 2002

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.

ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5
times.
13 ABORT The TN765 circuit pack has not been reset yet or is currently
being reset.
1. Retry the command at 1-minute intervals a maximum of 5
times.
2. If test continues to abort with error code 13, then check status
of all BX.25 and/or ISDN-PRI links on this TN765 via the
status link lnk-no command. If all links are not in-service,
then reset the TN765 using the test interface PCS long
command.
3. If the TN765 fails to reset, refer to the PI-SCI section of this
manual.
4. Else, retry the test link lnk-no command.
5. If the test still aborts with error code 13 or from step 2, and
some links are in-service and a error code is still present,
escalate the problem.

FAIL Excessive Level 2 resets (SABM) on link.
16386 Excessive Level 2 I-frame retransmission. Possible noisy link.
1. See “PI-LINK”.
16388 FAIL Excessive LAPD invalid frame errors. Could be a noisy link or
problems with the near-end Processor Interface circuit pack or
with the far-end.
1. See “DS1-BD” for DS1 Interface circuit pack problems.
2. See “PI-LINK”.
