ATM Cross Talk Test (#1298) (TN2305/6 only)
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 d etector, and others), it runs as a
part of demand test onl y.
This test fails if either the TDM programmable log ic and/or the interface to the
DSP is not operating properly. F ai lur e of t hese components may r esult in on e-wa y
or noisy connections. Refer to Fig ure 9-9 for a sc hematic of this test.
NOTE:
Note: This test applies only to TN2305 and TN2306 circ uit 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 c onditions 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.
