36 • FXO interface configuration
Note
Verify that you have configured the dial-tone for the country in which the
SmartNode is installed. (see chapter 42,
“Tone configuration”
on page 524).
If the dial-tone is not configured for the proper country, the FXO interface
will not detect when the remote FXS switch is sending dial-tone.
Configuring the number of rings to wait before answering the call (optional)
An FXO port identifies an incoming call by detecting the ring from the FXS switch. The
ring-number
is a
configurable parameter which selects the number of rings before answering the incoming call, that is, before
going off-hook and establishing the call. The minimum value for
ring-number
is zero (0). With a ring-num-
ber of zero, the FXO interface never answers an incoming call.
Due to variations between countries, the proper setting may be 1 or 2. In the USA the Caller-ID (CLID) is sent
to the FXO port between the first and second ring, so a ring-number of 2 would be appropriate. On the other
hand, numerous countries send the CLID prior to the first ring, so the default setting of 1 would be satisfactory.
Mode:
Interface FXO
Example:
Configure the ring number to wait for CLID by setting the
count
to 2. The name of the specific FXO
interface is
pstn-local
.
node>enable
node#configure
node(cfg)#context cs
node(ctx-cs)[switch]#interface fxo pstn-local
node(if-fxo)[pstn-local]#ring-number 2
You can verify the change in configuration by using the
show running-config
command.
