Digium S400M Quad Channel Station Module (1S400MF)
The S400M FXS module allows the TDM800P card or TDM2400P card to terminate four analog telephones per module. Because of the modular design, a user can activate additional ports at any time with more S400M daughter cards. The S400M module passes all the call features any standard analog telephone line will support. Worldwide certifications are pending.
Function:
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.
