Descriptions and Error Code
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the TSI Crosstalk
Test (#6), for example, you may also clear errors generated from other tests in the
testing sequence.

2. Refer to the repair procedure described in XXX-BD (Common Port Circuit Pack) for a description
of this test.
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.
