Add Integrated Announcements/TN2501AP
Issue 10 June 2005 259
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 µ-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
Remember the following points when using the TN2501AP integrated announcement circuit
pack for the 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.
- flash cards.
- tape.
- magneto optical disks.
Before you start
Ensure that you have the required hardware (see Hardware specifications).
