Gateway Configuration
This chapter describes how to configure gateways-specific parameters.
Analog Line Type
You can set the analog line type based on the analog signalling method used for each line of the Mediatrix
1204. This method defines the way on-hook and off-hook conditions are detected in a voice network.
X
To set the analog line type:
1. In the fxoMIB , set the analog telephone line type in the fxoIfAnalogLineType variable.
The default value is loopStart .
Because this variable is located in a table, you can define a different type for each line of the
Mediatrix 1204.
2. Restart the Mediatrix 1204 so that the changes may take effect.
Dialing Settings
Dialing settings allow you to configure how the Mediatrix 1204 dials numbers. These settings apply only to IP
network to SCN calls.
You can also set these parameters via the web interface, as described in “FXO Port” on page 79 .
X
To set the dialing settings:
1. In the analogScnGwMIB , locate the analogScnGwIfDialingTable group.
2. Set the dial prefix in the analogScnGwDialPrefix variable.
The dial prefix is a DTMF sequence to dial on the SCN before dialing the destination phone number.
For instance, this allows to configure the Mediatrix 1204 in offices that require to dial a specific digit
such as “9” before receiving a dial tone.
The dial prefix can be any combination of DTMFs or pause characters. The Mediatrix 1204 supports
the following pause characters:
• p
• ;
• ,

Type Description
loopStart A way of signalling that seizes a line by bridging both wires of
the telephone line through a resistor. The average telephone
line uses the loop start signalling method.
groundStart A way of signalling on subscriber trunks in which one side of
the two wire trunk is momentarily grounded to get dial tone.
The ground start signalling method ensures proper far end
disconnect between an FXO interface and the SCN.
