Specifies the terminating impedance of voice analog
interfaces.
other - none of the following; arbitrary,
within limits, for special cases.
ohms600Real - 600 Ohms.
ohms600Complex - 600 Ohms + 2.16uF
ohms900Complex - 900 Ohms + 2.16uF.
ohmsComplex1 - complex 1;
220 Ohms + 820 Ohms || 115nF.
This impedance is primarily used in
Germany.
ohmsComplex2 - complex 2;
270 Ohms + 750 Ohms || 150nF.
This impedance is primarily used in
United Kingdom and Sweden.
