coMsat Multichannel PRA

Multichannel PRA
• Constant Extension length: The last n digits are interpreted as the extension, the
rest (to the left) as CLI, where n is given in Length of the constant part
After splitting the calling number into CLI and extension, the CLI will be prefixed by
the Prefix for CLI reconstruction (if any is given) and sent together with the
extension in a SETUP message to the PBX.
Note: The SETUP is sent immediately, independently from the settings in the Dial
mode parameter.
Example: A call comes in from the number 05498765 to the extension 1234.
According to the settings in the above screen copy the four displayed channels 1 to 4
(left to right) will expect the following CLI:
Channel 1: 05498765#1234
Channel 2: 054987651234
Channel 3: 4987651234
Channel 4: 4987651234
In all four cases the resulting SETUP to the PBX will have the Calling number (CLI)
05498765 and the Called number 1234.
The CLIR Encoding can be used by the network to signal a call with the CLI rejected
to the Multichannel PRA. If a string is entered in this field and the CLI is equal to that
string the call will be signaled to the PBX as PRIVATE by omitting the CLI in the
SETUP message.
Example: A call comes in on channel 1 from 0#1234. The resulting CLI would be 0.
Since this is given as CLIR Encoding string, the CLI is not sent to the PBX.
6.5.3 TDMA parameters
These parameters are for use with TDMA modules.
Normally you only have to give the MIN (directory number) of the module and the SID
(System ID) of the home network.
If a TDMA module logs in to an analog AMPS network you can try enter 2 or 3 in the
EDSS parameter to prevent this.
6.5.4 Service parameters
These parameters are not intended to be changed by the user. They are for service
purposes only.
