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 p oint, the system is still
operating properly, but the system capacity is reduced.
The above events can occur i f:
1. The threshold number of General Purpose Tone Detector Ports
(GPTD-PTs) for service or the threshold number of D ual Tone
Multifrequency Receiver Ports (DTMR-PTs) for service is administered
incorrectly on a Tone Detector circuit p ack.
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 p orts have been either
busied-out by system tec hnician or maintenance has taken them
out-of-service).
3. Too many ports have been taken out-of-service for a Call Classi fier circuit
pack (that is, the por ts 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 insuffic ient number
of ports in the system for a Call Classifier c ircuit 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 describ ed in Step 2 for the DTMR-PT, the GPTD-PT , or
the CL SFY-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 p acks or for CCRs on the Call Classifier Port (CLSFY-PT)
circuit pack. If a th reshold value is set too high, cha nge it to a lower value
via the change system-parameters maintenance command and wait
one minute for the alarm to clear.
