Procedure P
If the digital voice module system normal LED is off, the digital voice module system trouble LED is on, and the digital voice module
trouble indicator LED flashes a 1-blink pattern, a memory retention battery trouble has been detected. A memory retention battery
trouble error may be caused by:
1.
Disconnected memory retention battery.
2.
Failed memory retention battery.
3.
Failed battery charging or supervision circuitry on the digital voice module.
If the error was due to one of the first two causes, the trouble will clear the first time the battery is checked after the cause is
corrected. Note that the battery is checked by the circuitry once every five minutes.
When a battery trouble error is indicated, perform the following:
1.
Check connection of memory retention battery.
2.
Replace memory retention battery.
If after the above procedure is completed, the trouble condition persists, the trouble condition is caused by failed circuitry on the
digital voice module. There are no field correctable failed circuitry problems on the digital voice module. Digital voice modules with
failed circuitry shall be replaced immediately, following the “SAFEPATH Module Replacement Procedure”, set forth previously in this
section.
Procedure Q
If the digital voice module system normal LED is off, the digital voice module system trouble LED is on, and the digital voice module
trouble indicator LED flashes a 2-blink pattern, a message memory I.C. error has occurred. A message memory I.C. error may be
caused by:
1. No messages programmed into message memory I.C.'s.
2. Missing or improperly installed message memory I.C.'s
3. One or more of the messages were not programmed completely.
4. Failed circuitry on the digital voice module.
If the error was due to one of the first three causes, the trouble will clear automatically when the cause is corrected. The first three
causes should only occur when power is first turned on to the digital voice module.
When a message memory error is indicated, perform the following:
1.
Verify that there is at least one message programmed into the message memory I.C.'s.
2.
Verify that all message memory I.C.'s are inserted into their sockets properly.
3.
Verify that new blank I.C.'s were installed into the digital voice module in the correct order. Example: An I.C. must be installed
in S64 before an I.C. can be installed in S65; I.C.'s must be installed in S64 and S65 before an I.C. can be installed in S66, etc.
Note that an I.C. must always be installed in S63.
4. Verify that there are no partially programmed messages on the message memory I.C.'s. This must be done using commands
on the serial port.
If, after the above procedure is completed, the trouble condition persists, the trouble condition is caused by failed circuitry on the
digital voice module. There are no field correctable failed circuitry problems on the digital voice module. Digital voice modules with
failed circuitry shall be replaced immediately, following the “SAFEPATH Module Replacement Procedure”, set forth previously in this
section.
