79 Matrix SETU VFXTH System Manual
High signifies 20Mohm Ringer Impedance. This is the default Ringer Impedance provided on the line side
by the DAA module of the FXO Port. The DAA Module can provide higher impedance when Synthesized
impedance is selected.
Some countries like Poland, South Africa and Slovenia require higher ring impedance which is achieved by
the DAA module, when Ringer Impedance is set to Synthesized impedance.
Default: High.
• Set the Ringer Threshold to the desired value. This parameter defines the level below which the FXO
Port would not validate the Ring signal and the level above which it validates the Ring signal. Set Ringer
Threshold from the following options:
• 13.5 - 16.5
• 19.35 - 23.65
• 40.5 - 49.5
Default: 13.5 - 16.5 Vrms.
• Click Submit to save.
• To configure the next FXO Port click the FXO Port number tab and follow the same instructions as given
earlier.
Copy Port Settings
You can also copy the settings of one FXO Port to another FXO Port using the Copy button. To do this,
• Click the Copy button. The Copy FXO Port Parameters window opens.
• In the Copy FXO Port box, select the number of the port you want to copy settings From. In the to FXO
Port box, select the number of the port you want to copy the settings To.
• Click the OK button and close the window.
• Once you have copied the settings, you can again edit the specific parameters of the FXO Port you copied
the settings to.
