To determine the correct thresholds, first find the total number of
TN478/TN420 Tone Detector and TN744 Call Classifier circuit packs in the
system using the
list configuration
command. Then calculate the total
number of tone receiver ports of each type. Each Tone Detector circuit
pack has 4 TTR (DTMR) ports and 2 CPTR (GPTD) ports. Each TN744 Call
Classifier circuit pack has 8 Call Classifier (CLSFY-PT) ports.
For each type of tone receiver, if the total number of ports installed in the
system is less than the administered threshold, then either add more
circuit packs to the system or reduce the threshold to match the number
already in the system. If the TTR Level alarm is still present, then proceed
to Step 3.

Display errors
for error type 18 and look for GPTD-PTs, DTMR-PTs, or
CLSFY-PTs that have been busied out.
For each of the busied-out ports:
■ Determine why the port was busied out.
■ If the port can be placed back into service, then test the port via the
test port UUCSSpp
command.
■ If all tests pass,
release port
and wait 1-minute for the TTR Level
alarm to clear.
If this does not clear the TTR Level alarm, proceed to Step 4.

If this does not clear the TTR Level alarm, replace the Tone Detector or
Call Classifier circuit pack with the alarmed GPTD-PT, DTMR-PT or
CLSFY-PT.
