circuit packs, and through another EI circuit pac k to a tone detector in the other
cabinet. The connections are the n reversed and the tone is passed in the
opposite directi on. If the system is equipped with a Center Stage Switch, and this
test either fails or aborts with the above connection, a second PN is c hosen (if
one is available and the EI circui t pack is In-Service) and the same test is run on
this new connection. This helps in the isola tion of the fault. Since two EI circuit
packs are involved in the c onnection, either one of them could be at fault and this
repeated test can help determine which is actually at fault.
The path used in this test is represented in Figure 9-43.

Result Description/ Recommendation
1002 ABORT The system could not allocate time slots for the test. The system may be under
heavy traffic conditions or it may have time slots out of service due to TDM-BUS
errors. Enter display errors and follow associated repair procedures for
TDM-BUS errors.
1. If system has no TDM-BUS errors and is not handling heavy traffic, retry the
command at 1-minute intervals a maximum of 3 times.
