ATM Cross Talk Test (#1298)
This test is nondestructive. 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 can result in 1-way or noisy connections.
Refer to Figure 29: ATM Cross Talk Test #1298 schematic
on page 568 for a schematic of this
test.
Note:
Note: This test takes approximately 12 minutes and applies only to TN2305 and
TN2306 circuit packs.

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