Digium TDM2400P - Twenty Four FXS / FXO Ports Max

The TDM2400P is a base board that supports FXS (green) and FXO (red) quad port modules. The TDM2400P commonly is used with the Open Source asterisk IP PBX (and variants) to connect to traditional, analog telecommunication equipment. Adding FXS or FXO modules to the TDM2400P base board creates bundles and changes the model number in a structured way. For instance the TDM2401B includes a TDM2400P and one quad port FXO module.

• The TDM2400P can have a maximum of 24 FXS and/or FXO ports (4 per module).
  
• An FXS interface connects an analog telephone or fax machine to asterisk.
  
• An FXO interface connects asterisk to an analog telephone line provided by the telephone company; ex: AT&T.
