System Technician-Demanded Tests:
Descriptions and Error Code
Always investigate tests in the order presented in
below when
inspecting errors in the system. For example, by clearing error codes associated
with the TSI Crosstalk test (#6), you may also clear errors generated from other
tests in the testing sequence.
TSI Crosstalk Test (#6)
This test is nondestructive.
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 can 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.
