The X100M FXO module allows you to connect an additional analog PSTN telephone line to your existing TDM400, TDM410, TDM800 or AEX800.

Because of the modular design, a user can activate additional ports at any time with more X100M or S110M daughter cards. The X100M module passes all the call features any standard analog telephone line will support. Worldwide certifications are pending.

You can also add the S110M FXS Module to connect more analog telephones to your Digium analog card.
