CHAPTER72 Configuration Parameters Reference
Mediant 800 Gateway & E-SBC | User's Manual
Table 72-61:General FXO and FXS Parameters
Parameter Description
'Update Port Info'
[AnalogPortInfo_x]
Defines a descriptive name for an analog port. This can
be used to easily identify the port.
The valid value is a string of up to 40 characters. By
default, the value is undefined.
Note:
■ For the ini file parameter, the x denotes the port
number.
■ To configure a port name through the Web interface,
see Configuring Name for Telephony Ports.
FXS Parameters
'FXS Coefficient Type'
configure voip >
interface fxs-fxo > fxs-
country-coefficients
[FXSCountryCoefficients]
Determines the FXS line characteristics (AC and DC)
according to USA or Europe (TBR21) standards.
■ [66] Europe = TBR21
■ [70] USA = (Default) United States
Note: For the parameter to take effect, a device reset is
required.
FXO Parameters
'FXO Coefficient Type'
configure voip >
interface fxs-fxo > fxo-
country-coefficients
[CountryCoefficients]
Determines the FXO line characteristics (AC and DC)
according to USA or TBR21 standard.
■ [66] Europe = TBR21
■ [70] USA = (Default) United States
Note: For the parameter to take effect, a device reset is
required.
configure voip >
interface fxs-fxo > fxo-
dc-termination
[FXODCTermination]
Defines the FXO line DC termination (i.e., resistance).
■ [0] = (Default) DC termination is set to 50 Ohms.
■ [1] = DC termination set to 800 Ohms. The
termination changes from 50 to 800 Ohms only when
moving from onhook to offhook.
Note: For the parameter to take effect, a device reset is
required.
configure voip >
interface fxs-fxo >
enable-fxo-current-limit
[EnableFXOCurrentLimit]
Enables limiting the FXO loop current to a maximum of
60 mA (according to the TBR21 standard).
■ [0] = (Default) FXO line current limit is disabled.
■ [1] = FXO loop current is limited to a maximum of 60
mA.
Note: For the parameter to take effect, a device reset is
required.
[EnableAnalogOverloadProtection] Enables electrical overload protection on FXO
interfaces.
■ [0] = (Default) Disable.
