Parameter country-name: Specifies a country so that its impedance standard is used. It can be
Australia, Austria, Belgium-Long, Belgium-Short, Brazil, China, Czech-Republic,
Denmark, ETSI-Harmanized, Finland, France, German-Swiss, Greece, Hungary,
India, Italy, Japan, Korea, Mexico, Netherlands, Norway, Portugal, Slovakia, 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.
Description Use the
impedance command to configure the current electrical impedance on
an FXO voice subscriber line.
Use the
undo impedance command to restore the default.
By default, the electrical impedance on the FXO voice subscriber line applies to
China.
You can specify an impedance value by specifying the country where the value
applies. You may just input the leading letters that uniquely identify a country
without inputting a complete country name, however.
Example # Configure the current electric impedance to r600 on voice subscriber line 1/0.
