ETR-PT (Enhanced Tone Receiver Port)

1. Use list configuration carrier to get the board type and location. If the board is
TN744, then do steps 2–4; if it is TN2182 or TN2312, do steps 5–12.
2. Execute three commands: busyout board location, reset board location,
and release board location. Reset is required to reload RAM associated with the
TN744’s DSPs. This will take all eight tone detector ports out of service for a few
seconds. Only four of the eight would be out of service due to the alarm. (There are four
tone detectors on each of the two DSPs.) Other than the unlikely potential of running out
of tone detector resources in the switch, there is no other effect when the board is reset.
3. Test the board (test board location long).
4. If the test passes, terminate the repair process. If the test fails, replace the board.
5. Check to see if the board is duplicated (list cabinet and status port-network
on the affected PN).
6. If the board is not duplicated, use test tone location long to resolve the error.
The long test resets the board and is required to reload on-board RAM associated with
the DSPs. The effect is that tone detectors are taken out of service momentarily and
tones are removed from the TDM bus for about 10 seconds. This means no dial pulses or
touch tones during this interval, which probably will not affect calls in progress but could
cause a call origination to abort or cause a user to not get dial tone when going off hook.
7. If every test passes and the alarm does not resolve, retest (test tone location
long clear).
8. If the test passes, terminate the repair process. If it fails, replace the circuit pack at the
customer’s convenience.
9. If the board is duplicated, switch to the standby side (set tone/set
ipserver-interface).
10. Test the alarmed board (test tone location long). This resets the board and is
required to reload on-board RAM associated with the circuit pack’s DSPs.
11. If every test passes and the alarm does not resolve, retest with test tone location
long clear.
12. If the test passes, terminate the repair process. If it fails, replace the board.
b. Error Type 257: The ETR-PT lost its translation. Testing the ETR-PT is sufficient to reload
its translation. If testing the ETR port does not clear the error, then the circuit pack
containing the defective ETR port should be replaced at a time when it is convenient to
remove a clock board from the system. Follow the procedures described in TONE-BD
(Tone-Clock Circuit) on page 2327 for replacing a Tone-Clock circuit pack.
c. Error Type 513: This error indicates the (ETR-PT) Enhanced Tone Receiver is having
problems detecting touch tones, call-progress tones, or MFC tones. If this error type is
persistently logged, then the circuit pack containing the defective ETR-PT should be
replaced at a time it is convenient to remove a clock board from the board from the system.
