The card will work as long as you have PVDM modules installed.

Are you sure you have the right card in mind?

FXO accepts dial tone from an analog POTS line. FXS provides dial tone to devices like a fax machine, analog phone etc.

To simplify on the answer agonza07 provided
The options.

Telco BRI/PRI<===========>
                                                 \\
Telco POTS <=> FXO port <=>2911 <=>FXS<=>phone/fax
                                                     \\
                                                        <=> switch IP phones

Or maybe i can just branch off the line from the 66 block and have it going off to the fax and going off to the fsx for srst.  Sorry im a little new at this and have to learn as i go.

For any device phone/fax you would need an FXS port/s.

You could have the fax directly connected to the telco's POTS line.

the SRST needs an outside line, which is delivered via the FXO port to the 2911.
