ATM Cross Talk Test (#1298)
This nondestructive ATM Cross Talk test makes sure that TDM time slots are
correctly allocated to connections. It is useful for diagnosing one-way or noisy
connections. The test fails if the TDM programmable logic and/or the interface to
the DSP is not operating properly. The test can take more than 10 minutes.
Figure 3-182
shows a diagram of this test, substituting “CES mode” for “PNC
mode.”
XYZ FAIL There is at least one bad DSP on the board. The
X
value indicates the
number of bad talker DSPs,
Y
indicates the number of bad listener DSPs
and
Z
indicates the number of bad echo canceler DSPs.
1. Test the Active Tone-Clock on the port network that contains the
ATM-TRK circuit pack for dial-tone. Repair as needed.
2. Repeat the short test on the ATM-TRK circuit pack.
3. If the test continues to fail, check for service-affecting MINOR alarms. If
a MINOR alarm is raised for Error Type 2817 or 1818, replace the circuit
pack.
4. If a WARNING alarm is raised, this is a non-service-affecting error, and
the circuit pack can still process calls.
XY8 PASS The test passed for some or all DSPs. XY8 indicates the number of talker,
listener, and echo-canceler DSPs for which the test passed (the rest of the
DSPs were skipped). The
X
value indicates the number of good talker DSPs,
Y
indicates the number of good listener DSPs and
Z
indicates the number of
good echo canceler DSPs.
0NO
BOARD
No board detected.
1. Check the Error Log for wrong board Error 125 (wrong board) or Error
131 (no board). Replace or insert the circuit pack if necessary.
2. Check that the board is properly translated and inserted.
3. If Error 1538 (hyperactivity) is listed in the Error Log, and run reset
board UUCSS.
4. Run the test again, and, if it fails, replace the ATM-TRK circuit pack.
5. Retest.
