ATM Cross Talk Test (#1298)
This test is non-destructive. The ATM board Cross Talk test verifies that the
selected TDM bus time slot never c rosses over to time slots reserved for other
connections. The test also chec ks for cross connections, where the b oard talks
to time slots other than those specified . Since this test uses many system
resources (TDM time slots, tone generator, tone detec tor, and others), it runs as a
part of demand test only.
This test fails if either the TDM programmable log ic and/or the interface to the
DSP is not operating properly. Failure of these components may result in one- way
or noisy connections. Refer to Figu re 3-7 for a sc hematic of this test.
NOTE:
Note: This test takes approximately 12 minutes and applies only to TN2305
and TN2306 circuit pac ks.

Result Description/ Recommendation
ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals for a maximum of 5
times.
1002 ABORT The system could not allocate time slots for the test. The system may
be under heavy traffic conditions or it may have time slots
out-of-service due to TDM-Bus errors. Refer to TDM-BUS to diagnose
these errors.
1. If system has no TDM-Bus errors and is not handling heavy
traffic, repeat test at 1-minute intervals for a maximum of 5 times.
