TSI Crosstalk Test (#6)
This test is non-destructive.
The Time Slot Interchanger (TSI) chip controls connectivity to the TDM bus. The
TSI Cross Talk Test verifies that this TSI talks on the selected TDM bus time slot
and never crosses over to time slots reserved for other connections. If the TSI is
not working correctly, one-way and noisy connections may occur. If the test
passes, then the TSI is able to communicate over the TDM bus. This test is part of
the circuit pack’s demand and scheduled long test sequence, and takes
approximately 20 to 30 seconds to complete.

ABORT
Internal system error. This is an abnormal abort.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1002
ABORT
The system could not allocate time slots for the test, the traffic load on the
system is very high, or the time slots are out-of-service due to TDM-BUS errors.
Refer to “TDM-BUS” to diagnose any active TDM Bus errors.
system is very high, or the time slots are out-of-service due to TDM-BUS errors.
Refer to “TDM-BUS” to diagnose any active TDM Bus errors.
1. If the system has no TDM-BUS errors and is not handling heavy traffic,
repeat the test at 1-minute intervals a maximum of 5 times.
