    FXOS-200 is a Dual-channel module, which builds 1 FXO and 1 FXS channel with failover capability. When PBX system is down, PSTN line connecting FXO will automatically switch to analog phone connecting with FXS.

    Because of the modular design, users can activate additional ports at any time with more FXS-200, FXO-200 or FXOS-200 modules. These modules pass all the call features any standard analog telephone line 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.
