TDM-BUS (TDM Bus)

System Technician-Demanded Tests:

Descriptions and Error Codes

Always investigate tests in the order presented in the table below. For example,

by clearing error codes associated with the Control Channel test (#296), you may

also clear errors generated from other tests in the testing sequence.

Order of Investigation

Control Channel test on the Control Channel Bus (#296)

Digit Detection test on the Non-Control Channel Bus (#297)

Idle Time Slot test (#294)

D = Destructive; ND = Nondestructive

Idle Time Slot Test on TDM bus A or B (#294)

The Idle Time Slot test detects noisy time slots on the bus and takes them

out-of-service. The Tone Detector circuit pack is told to listen to idle time slots and

if it detects any noise on a time slot, it returns a failure. At the end of the test, any

out-of-service time slots are retested to see if they are still noisy and restored to

service if they are idle. After every time slot has been tested, maintenance counts

the number of bad time slots and reports the number to the technician in the error

code field. No more than 220 time slots will be taken out-of-service on one bus

and no more than 300 will be taken out-of-service on both buses at one time.
