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.
