Before you start
Ensure that the announcement administration is complete before proceeding. You must have assigned a
name before you can record an announcement (see
If you are replacing a TN750C announcement circuit pack with the TN2501AP,
•
get a list and description of the announcements stored on the TN750C circuit pack.
•
re-record the announcements on a computer or at a professional recording studio as .wav files
(CCITT -Law or A-Law, 8KHz, 8-bit mono), so that they are ready to transfer to the new
announcement circuit pack after it is installed and administered.
Replacing old announcement circuit packs with the new TN2501AP circuit pack requires that you
•
remove previous announcement administration
•
record new announcements for the TN2501AP
•
re-record any announcements currently resident on the TN750 circuit packs that you are
replacing. You cannot transfer or restore TN750 announcements from flash card, tape, or optical
disk to the TN2501AP.
CAUTION:
When you change a VAL announcement, the TN2501AP 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. For information on viewing denial events, see
page 396.
Announcement file format requirements
In order to be compatible with the TN2501AP circuit pack and Avaya Communication Manager,
announcement recordings must have the following parameters:
•
CCITT A-Law or CCITT -Law companding format (do not use PCM)
•
8KHz sample rate
•
8-bit resolution (bits per sample)
•
Mono (channels = 1)
•
The -Law (Mu-Law) companding is used in the United States and A-Law is used internationally.
Use the companding format specified on the Location Parameters screen.
•
File names for the TN2501 (VAL) boards cannot contain blank spaces nor any of the following
characters: '.', ',', '/',':', '*','?', '<', '>', '\'. The file name itself is case sensitive, but the .wav file
extension must be lower case.
Announcements that are recorded in this format occupy 8K bytes per second of file space for every
second of recorded speech. For example, a 10-second announcement creates an 80K bytes .wav file.
Professional or computer recordings
In order to be compatible with the TN2501AP circuit pack and Avaya Communication Manager,
announcement recordings must meet the announcement file format requirements described in the
preceding section.
