Non-Volatile Storage of Announcements on VAL
The VAL board has a RAM based file system on which the announcements are stored.
This is where a newly recorded or FTP'd announcement resides. The VAL constantly
checks to determine whether changes have been made to the file system (file
added or deleted or renamed). Once a change has been detected, the VAL waits for
5 minutes of stability. After such a stable period, the VAL backs up the RAM
based file system to its FLASH. The FLASH version of the file system is
non-volatile and is what is restored upon reset/reseat. If you record a new
announcement and immediately reset the board, the announcement will be
lost. The yellow LED blinks while a backup from RAM to FLASH occurs. All of the
above is true regardless which (if any) of the .wav files on the board are
administered announcements. It is just the way the board (firmware) operates.
Note that only files with a .wav extension in the /annc directly are backed up
to FLASH.
CAUTION: When you change a VAL announcement, the TN2501AP circuit pack or media
gateway v VAL source is activated to perform a Flash auto-save backup
5 minutes later. If you try to record a new announcement during this backup
process, the new recording fails, and a denial event is logged to the Event
Report screen.
