Digium analog modules pass all the call features any standard analog telephone line will support.
The S110M FXS module allows the TDM400P card or TDM800P card to terminate analog telephones.
Because of the modular design, a user can activate additional ports at any time with more S110M or X100M daughter cards. The S110M module passes all the call features any standard analog telephone will support.
FXS - Foreign Exchange Station
FXO - Foreign Exchange Office
An FXS device initiates and sends ringing voltage. An FXO device receives the voltage sent by the FXS device.
The phone receiving the call is the last FXO device in the chain, and when it receives voltage from an FXS device, the phone will ring.
Connect the outside line to an FXO port on your Asterisk server to receive voltage from the outside lines.
Connect the phones to FXS ports on your Asterisk server. When the FXO module in your Asterisk Server receives the voltage, it will then generate voltage using the FXS module and send it to your analog phone.
