Howdy,

For analog stations, you want to use FXS on the modular analog cards. FXO handles the PSTN trunks.

FXS provides ringing voltage and battery to analog stations (phones).

For Digital phones, we don't offer anything, I'm afraid. They're all proprietary.

Alright thank you for your repky, the FXS you mentioned here, it's something (such as a hardware) that I will connect to the module card, the same card that use to integrate the Analogue phone line(PSTN),I know Analogue phone line card provides FXO ports.
Thanks!

The analogue line cards that Digium sell have sub-modules that can either be FXO or FXS ones, and you can buy the boards with no sub-modules installed, or with various combinations. If you have a Digium card that is populated as all FXO, you can unplug some of the FXO sub-modules and replace them with FXS ones.

Note, as a Digium employee, Malcolm is only going to give you solutions sold by DIgium. However, if you use a PCI card based solution, other than a Digium one, you will find it difficult to get any support on these forums.
