FXO interface configuration task list

SmartWare Software Configuration Guide 

Verify that you have configured the dial-tone for the country in which the 
SmartNode is installed. (see chapter 42,

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.

An FXO port identifies an incoming call by detecting the ring from the FXS switch. The 

 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 

 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.
