System Technician-Demanded Tests:
Descriptions and error codes
Investigate problems in the order presented. When you clear one of the error
codes associated with a test, you clear errors generated by other tests in the
testing sequence. If you clear errors out of order, you can lose important
information.
Connection Audit Test (#50)
Nondestructive (in a sane switch environment).
The Connection Audit test updates TDM time slots. It sends network-update
Control Channel Message Set (CCMS) messages that tell the ATM-TRK circuit
pack to listen to, talk to, or disconnect particular time slots.
The test passes if software successfully sends the downlink network-update
messages. It aborts otherwise.
!
CAUTION:
Though normally nondestructive, this test could unintentionally tear down an
active call if the connection-manager software’s tables are corrupt.
