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.
