To determine the correct thresholds, first find the total numb er 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 por ts of each type. Each Tone Detector circuit
pack has 4 TTR (DTMR) ports and 2 CPTR (GPTD) ports. Each TN744 Call
Classifier circuit pac k has 8 Call Classifier (CLSFY-PT) ports.
For each type of tone receiver, if the total numb er 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 matc h the number
already in the system. If the TTR Level alarm is still present, then proc eed
to Step 3.
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 po rts:
■Determine why the port was busied out.
■If the port can be p laced back into servic e, then test the port via the
test port UUCSSpp command.
■If all tests pass, release port and wait 1-minute for th e TTR Level
alarm to clear.
If this does not clear the TTR Level alarm, proceed to Step 4.
4. Display alarms and determine the loc ation of the circuit pack with the
alarm ed GPTD -PT, DTMR- PT, or GPTD- PT.
Test board UUCSS long rep 3 for that circuit pa ck.
If this does not clear the TTR Level alarm, replace the Tone Detector or
Call Classifier circuit pac k with the alarmed GPTD-PT, DTMR-PT or
CLSFY-PT.
