Maintenance Objects
3-1160TTR-LEV (TTR Level)

2. The total number of Dual Tone Multifrequency Receiver Ports (DTMR-PTs)
[(also known as Touch Tone Receiver (TTRs)], currently in service is less
than the administered threshold number.
The TTR Level maintenance performs a monitoring function. When one of the
above events occurs, the switch reports it. At this point, the system is still
operating properly, but the system capacity is reduced.
The above events can occur if:
1. The threshold number of General Purpose Tone Detector Ports
(GPTD-PTs) for service or the threshold number of Dual Tone
Multifrequency Receiver Ports (DTMR-PTs) for service is administered
incorrectly on a Tone Detector circuit pack.
2. Too many General Purpose Tone Detector Ports (GPTD-PTs) or Dual Tone
Multifrequency Receiver Ports (DTMR-PTs) have been taken out-of-service
for a Tone Detector circuit pack (that is, the ports have been either
busied-out by system technician or maintenance has taken them
out-of-service).
3. Too many ports have been taken out-of-service for a Call Classifier circuit
pack (that is, the ports have been busied-out by system technician or
maintenance has taken them out-of-service).
4. There is an insufficient number of General Purpose Tone Detector Ports
(GPTD-PTs) or Dual Tone Multifrequency Receiver Ports (DTMR-PTs) in the
system for a Tone Detector circuit pack. Or there is an insufficient number
of ports in the system for a Call Classifier circuit pack.
Repair Procedure for the TTR Level Maintenance
Object
The following is a step-by-step approach to resolve the TTR Level maintenance
alarm.
1. Execute the
display error
command. Determine if the TTR-LEV warning
alarm is raised against the GPTD-PT level, the DTMR-PT level, or the
CLSFY-PT level. In the Hardware Error Log Table, the error type field of the
TTR-LEV MO has a value of 2 for DTMR-PT level, a value of 4 for GPTD-PT
level, or a value of 6 for CLSFY-PT level.
Perform the actions described in Step 2 for the DTMR-PT, the GPTD-PT, or
the CLSFY-PT.
2. Issue the
change system-parameters maintenance
command. Check
the administered value(s) for TTRs and CPTRs for service on the Tone
Detector circuit packs or for CCRs on the Call Classifier Port (CLSFY-PT)
circuit pack. If a threshold value is set too high, change it to a lower value
via the
change system-parameters maintenance
command and wait
one minute for the alarm to clear.
