Announcement File Specifications; Caveats; Installation, Upgrades And Additions For Avaya Cmc1 Media Gateways June; Before You Start - Avaya CMC1 Installation Manual

CAUTION:
Before you remove a TN750A or B circuit pack from its carrier, ensure that you have
backed up the announcements that are stored on it. Once you remove the circuit pack from
the carrier, power is lost along with the announcements.
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.

Announcement File Specifications

The TN2501AP circuit pack, Voice Announcement over LAN (VAL), requires that announcement files
are in the following .wav formats:
•
CCITT A-Law or CCITT -Law companding format (do not use PCM)
•
8KHz sample rate
•
8-bit resolution (bits per sample)
•
Mono (channels = 1)
All previously-recorded announcements must be converted to these file formats to work on the
TN2501AP circuit pack. Announcements recorded through the direct telephone access are automatically
recorded in the correct file formats.

Caveats

first time or when replacing the TN750C circuit pack:
•
Despite the feature name, announcements are not played over the LAN but can be transferred to
and from the TN2501AP circuit pack over the LAN.
•
You cannot save or restore announcements to a TN2501AP circuit pack to/from
— a TN750C circuit pack.
