1.2.5 Configuring Voice Port
The router provides analogue voice ports for the implementation of the VoIP. The
signaling type of these analogue voice ports depends upon the VI (Voice Interface)
board installed. The command voice-port is used to configure the characteristic s
related to the special voice port signaling type.
The voice port support the following three basic voice signaling t ypes:
z FXS (Foreign eXchange Station): FXS port used the standard RJ-11 line to
directly connect with the device such as ordinary phone set, fax, PBX, etc., which
can provide ring, voltage and dial tone.
z FXO (Foreign eXchange Office): two wire loop trunk, the FXO port uses RJ-11 line
to connect the local calls to the PSTN central office or to the PBX tha t does not
support the E&M signalings. The FXO port device can only connect to device with
FXS port.
z E&M: The E&M por t uses the RJ -45 line to co nnect the rem ote calls from the IP
network to the PBX trunk. The E&M signaling provides the on-hook and off-hook
signals and reduces the interference to some lower degree, which is usually used
in the PBX backbone or connection line.
The voice port configuration mainly involves the configuration of some ph ysical
characteristics. Usually, you can use defaults for the physical port parameters and do
not need to configure again.
Please use the command voice-port in the global configuration mode, and m ake other
configurations in the voice-port configuration mode.
