Version 7.2 795 Mediant 1000B Gateway & E-SBC
User's Manual 44. Software Upgrade
The prerecorded tones are played repeatedly. This allows you to record only part of the
tone and then play the tone for the full duration. For example, if a tone has a cadence of 2
seconds on and 4 seconds off, the recorded file should contain only these 6 seconds. The
device repeatedly plays this cadence for the configured duration. Similarly, a continuous
tone can be played by repeating only part of it.
44.1.5 Voice Prompts File
The Voice Prompts (VP) file contains a set of voice prompts (or announcements) and/or
.wav files that can be played by the device during operation. The voice announcements are
prepared offline using standard, third-party 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 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 787).
44.1.6 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).
To load CAS files see ''Loading Auxiliary Files'' on page 787.
Note: All CAS files loaded together must belong to the same trunk type (i.e., either E1
or T1).
