Digium X400M Quad Channel Trunk FXO Module - 1X400MF



                                                                                               Digium X400M Quad Channel Trunk FXO Module - 1X400MF

The X400M FXO module allows 800 Series or 2400 Series analog cards to terminate four (4) analog lines per module.

FXO (Foreign Exchange Office) is an interface that connects to a trunk line, like the one from your service provider. It receives ringing voltage and battery from FXS devices. FXO interfaces are used to connect your PBX to the PSTN. One FXO channel is required for each line you receive from your telco.

Because of the modular design, you can activate additional ports at any time with more X400M daughter cards. The X400M module passes all the call features any standard analog telephone line will support.

All Digium analog and digital interface cards:

  • are RoHS compliant
  • are manufactured in an ISO 9001:2001 certified facility in the United States
  • maintain an MTBF greater than one million hours
  • are backed by a five-year hardware warranty
  • are backed by Digium's Exceptional Satisfaction Program (ESP)
