FXS-200 is a dual-channel module with an FXO channel and one FXS channel with failover capability. When the PBX fails, the line of the Public Switched Telephone Network (PSTN) connected to FXO will automatically switch to the analog phone connected to FXS.
The FXO400 Quad-FXO module allows OpenVox Analog A2410P/AE2410P series cards to terminate four analog telephone lines (POTS) per module.
