FXO interface examples
Example 1: Configuring an FXO interface which is to be connected to a PSTN network for analog line exten-
sion over IP. The FXS switch provides caller-id between the first and second ring and uses battery reversal to
indicate a connected call. The FXO interface is named pstn-local. The incoming call is routed directly to the
interface named pstn-1-voip.
node>enable
node#configure
node(cfg)#context cs
node(ctx-cs)[switch]#interface fxo pstn-local
node(if-fxo)[pstn-local]#connect-signal battery-reversal
node(if-fxo)[pstn-local]#ring-number 2
node(if-fxo)[pstn-local]#route call dest-interface pstn-1-voip
Example 2: Configuring an FXO interface to be used as fallback if the IP network link is down. This means
that there are only out-going calls. You are not sure whether the FXS switch provides a connect signal. In this
case, you only have to create the interface and bind the FXO port to the FXO interface. (For binding the FXO
port to the FXO interface, see chapter 44, “FXO port configuration” on page 542.)
