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.
Avaya Communication Manager announcement synchronicity
As mentioned above, there is a separation between the actual files on the VAL board and the
set of administered announcements. You can have 100 .wav files on a VAL and only be using
(administered) 5 of them. The best way to visualize this is to look at the difference between a
list integrated and the list directory board <brdloc>/annc commands.
By going into the Change Announcement screen and changing the name of an
announcement, what is happening? You are changing only the administration of the
announcement. This means when the extension is called, the new file name is requested. The
board still has a file with the old file name but not one with the new file name. You then could run
change announcement again and switch the name back to the old one and the
announcement will play fine. The VAL board is completely unaware that you change the
change announcement command.
