FXO interface configuration task list 421

SmartWare Software Configuration Guide 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 529).

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.

You can verify the change in conﬁguration by using the show running-conﬁg command.
