ohmsComplex1 - complex 1;
220 Ohms + 820 Ohms || 115nF.
This impedance is primarily used in
Germany.
ohmsComplex2 - complex 2;
270 Ohms + 750 Ohms || 150nF.

United Kingdom and Sweden.
What is cvaIfCfgImpedance?
This read-write INTEGER selects the terminating impedance of a voice analog interface, choosing among options like 600 Ohms real, 600 Ohms complex plus 2.16uF, or 900 Ohms complex, among others. An administrator sets this to match the interface's electrical characteristics to the connected analog equipment or line for proper signal transfer and echo performance. For example, setting this to ohms600Real matches an interface to equipment expecting a simple 600-Ohm resistive termination.
