Maintenance-Object Repair Procedures
555-233-143
8-546 Issue 1 May 2002
For TN754 vintage 14 or later, TN754B and TN2136, the PTC will open if
there is a short on the power line for 1/2 second or longer. The voice
terminal is probably not operating properly. Unplug the voice terminal for
30 seconds and then plug it back in. If the voice terminal still does not
operate, then check for a short in the wiring, a damaged jack, an incorrect
type of voice terminal, or a defective voice terminal.
Once the problem has been resolved, it may take up to 1 hour for the alarm
to clear due to “leaky bucket” strategy. If the problem cannot be resolved
by one of the steps above, then replace the circuit pack.
g. Error Type 1026—There is a problem with the voice terminal EEPROM.
When the voice terminal is repaired the alarm will be resolved with the
passing of time.
h. Error Type 1537—An in-line maintenance error has generated an
off-board warning due to some problem with the link to the voice terminal.
This can be ignored if no user complaints are received. Otherwise, make
sure the voice terminal is connected, check for defective wiring, check for a
defective voice terminal, and move voice terminal to a jack that is closer to
the switch (in terms of feet of wiring between the jack and the switch). If
the problem still exists, replace the circuit pack. Once the problem has
been resolved, the alarm will be retired after a predetermined amount of
time.
i. Error Type 2304—Internal system error. No action is necessary.
j. Error Type 2305 with Aux Data of 40967—This indicates that the station
went off-hook while it was in the ready-for-service state. Use the status
station command to determine the state of the station. The off-hook
should have moved the station to ready-for-service. No craft action is
necessary.
Error Type 2305 with Aux Data of 32770 —An in-line maintenance error
has generated an off-board warning due to some problem with the link to
the voice terminal. This can be ignored if no user complaints are received.
Otherwise, make sure the voice terminal is connected, check for defective
wiring, check for a defective voice terminal, and move voice terminal to a
jack that is closer to the switch (in terms of feet of wiring between the jack
and the switch). If the problem still exists, replace the circuit pack. Once
the problem has been resolved, the alarm will be retired after a
predetermined amount of time.
k. Error Type 2817—Port Level Hyperactivity—Fifty or more CCMS uplilnk
messages were received from the port within ten seconds. The user is
taken out of service for a short interval of time (default 30 seconds).
l. Error Type 3585—This error type indicates that an attempt to execute a
firmware download of a DCP terminal has failed. The DCP terminal must
be replaced before the firmware download can be executed successfully.
Replace the DCP terminal and re-execute the firmware download.
