impedance
Use impedance to set the current electrical impedance on an FXO or FXS voice subscriber line.
Use undo impedance to restore the default.
Syntax
impedance { country-name | R550 | R600 | R650 | R700 | R750 | R800 | R850 | R900 | R950 }
undo impedance
Default
The electrical impedance on the FXO or FXS voice subscriber line is the impedance value corresponding
to China.

Parameters
country-name: Specifies an applicable country. It can be Australia, Austria, Belgium-Long, Belgium-Short,
Brazil, China, Czech-Republic, Denmark, ETSI-Harmonized, Finland, France, German-Swiss, Greece,
Hungary, India, Italy, Japan, Korea, Mexico, Netherlands, New Zealand, Norway, Portugal, Slovakia,
South Africa, Spain, Sweden, U.K., US-Loaded-Line, US-Non-Loaded, or US-Special-Service.
r550: 550-ohm real impedance.
r600: 600-ohm real impedance.
r650: 650-ohm real impedance.
r700: 700-ohm real impedance.
r750: 750-ohm real impedance.
r800: 800-ohm real impedance.
r850: 850-ohm real impedance.
r900: 900-ohm real impedance.
r950: 950-ohm real impedance.
Usage guidelines
Each country corresponds to an impedance value. Thus, you can specify an impedance value by
specifying a country. You can just enter the leading letters that uniquely identify a country without
entering a complete country name, however.
Examples
# Set the current electric impedance to r600 on voice subscriber line 1/0.
