36.1.3 Voice Prompts File

The Voice Prompts (VP) file contains a set of voice prompts (or announcements) that can
be played by the device during operation. The voice announcements are prepared offline
using standard recording utilities and then combined into a single file using the DConvert
utility. The VP file can then be loaded to the device using the Web interface.
The VP file is a collection of raw voice recordings and/or wav files. These recordings can
be prepared using standard utilities such as CoolEdit and Goldwave
The raw data files must be recorded with the following characteristics:

Coders: Linear G.711 A-law or G.711 µ-law

Rate: 8000 kHz

Resolution: 8-bit

Channels: mono
When the list of recorded files is converted to a single voiceprompts.dat file, every Voice
Prompt is tagged with an ID number, starting with '1'. This ID is later used by the device to
play the correct announcement. Up to 1,000 Voice Prompts can be defined. If the size of
the combined VP file is less than 1 MB, it can be permanently stored on flash memory.
Larger files (up to 10 MB) are stored in RAM, and should be loaded again after the device
is reset.
The device can be provided with a professionally recorded English (U.S.) VP file.

To generate and load the VP file:
1. Prepare one or more voice files using standard utilities.
2. Use the DConvert utility to generate the voiceprompts.dat file from the pre-recorded
voice messages. For more information, refer to DConvert Utility User's Guide.
3. Load the voiceprompts.dat file to the device using the Web interface (see ''Loading
Auxiliary Files'' on page 575).

36.1.4 CAS Files

The CAS auxiliary files contain the CAS Protocol definitions that are used for CAS-
terminated trunks. You can use the supplied files or construct your own files. Up to eight
files can be loaded to the device. Different files can be assigned to different trunks
(CASTableIndex_x) and different CAS tables can be assigned to different B-channels
(CASChannelIndex).
The CAS files can be loaded to the device using the Web interface or ini file (see ''Loading
Auxiliary Files'' on page 575).
Note: All CAS files loaded together must belong to the same Trunk Type (i.e., either
E1 or T1).
