2. Set the dial tone detection timeout in the fxoDialtoneDetectionTimeout variable.
This indicates how long the Mediatrix 1204 waits, in milliseconds (ms), for a dial tone before it
considers the line is busy with an incoming SCN call.
3. Restart the Mediatrix 1204 so that the changes may take effect.
Line Fault Detection
The line fault detection mechanism allows to detect defective or disconnected lines based on the absence of
current when closing the loop.
X
To set the line fault detection feature:
1. In the fxoMIB , set the line seizure timeout in the fxoLineSeizureTimeout variable.
This variable indicates how long the Mediatrix 1204 waits before it considers the seizure of an
analog line failed.
2. Enable the line fault detection by setting the fxoLineFaultDetectionEnable variable to enable .
The line status appears in the fxoIfLineStatusTable :
• unknown: The line fault detection is disabled.
• connected: When last polled, the line was connected.
• disconnected: When last polled, the line was disconnected.
Incoming Call Not Allowed
Under certain circumstances (such as a locked line, the call direction set to 'IP to SCN only', etc.), incoming
calls from the SCN are not allowed. When that is the case, you can define the behaviour of the FXO lines.
X
To set the FXO line behaviour when incoming calls from the SCN are not allowed:
1. In the fxoMIB , set the behaviour in the fxoIfIncomingCallNotAllowedBehavior variable.
