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 crosses over to time slots reserved for other
connections. The test also checks for cross connections, where the board talks
to time slots other than those specified. Since this test uses many system
resources (TDM time slots, tone generator, tone detector, and others), it runs as a
part of demand test only.
This test fails if either the TDM programmable logic 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 Figure 3-7
for a schematic of this test.
NOTE:
Note: This test takes approximately 12 minutes and applies only to TN2305
and TN2306 circuit packs.

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.
