Mediatrix 1204 187
Special Case: Automatic Call
If the line is set up for automatic call (see “Automatic Call” on page 255 ), you can instruct the Mediatrix 1204
to wait until the called party answers the phone before it picks up the SCN line.
X
To configure the Mediatrix 1204 to wait before picking up the SCN line:
1. In the fxoMIB , set the fxoWaitForCalleeToAnswerEnable variable to enable .
The fxoPreAnswerDelay and fxoAnswerOnCallerIdDetectionEnable variables are not used.
Line Properties
Line properties allow you to define how the Mediatrix 1204 detects the actual status of a line.
Dial Tone Detection
This mechanism helps to avoid collisions between incoming and outgoing SCN calls. When enabling the dial
tone detection, the Mediatrix 1204 waits for a dial tone on the SCN before initiating the dialing sequence. If the
unit does not detect a dial tone, it considers the line as busy with an incoming SCN call.
X
To set dial tone detection:
1. In the fxoMIB , set the fxoDialtoneDetectionMode variable with one of the following values:
• disable: Dial tone detection is disabled.
• countryTone: The Mediatrix 1204 tries to detect the tone specified for this purpose in
the current country’s tone specification. Some country specifications omit this
information. In that case, the unit behaves as if
fxoDialtoneDetectionMode is set to
“disable”.
