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 all the time slots have been tested, maintenanc e
counts the number of bad time slots and reports the n umber to the technician in
the error code field. No more than 220 time slots are taken out-of-service on one
bus, and no more than 300 are taken out-of-servic e on both buses at one time.
