TTR-LEV (TTR Level)
Issue 4 May 2002 10-1827 555-233-123
The TTR Level (Touch Tone Receiver Level) MO is used to represent the following
possible events:
1. The total number of General Purpose Tone Detector Ports (GPTD-PTs),
[also known as Call Progress Tone Receivers (CPTRs)], currently in
service is less than the administered threshold number.
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.
