Repair Procedure for TTR-LEV

To resolve a TTR-LEV alarm:

1. Display errors and use the TTR-LEV Error Log Table to determine which

type of tone receiver has fallen below its threshold.

2. Enter change system-parameters maintenance, and check the

administered value. On the form, TTR represents DTMR-PTs, CPTR

represents GPTD-PTs, and Call Classifier represents CLSFY-PTs. If the

threshold value is set too high, change it to a lower value and wait a minute

for the alarm to clear.

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:

If this does not clear the TTR Level alarm, proceed to Step 4.

4. Display alarms and determine the location of the circuit pack with the

alarmed GPTD-PT, DTMR-PT, or GPTD-PT.

Test board UUCSS long rep 3 for that circuit pack.

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

Issue 1 May 2002

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 every test passes, release port and wait 1 minute for the TTR

Level alarm to clear.
