Mitel 4 Port FXS for EX Cont - 50008231
The Mitel 50008231 is a four-port FXS analog station interface card designed specifically for the Mitel EX Controller platform running MiVoice Business. It provides four RJ-11 FXS connections for integrating compatible analog telephones and other supported analog station devices into an EX Controller deployment.
Each 50008231 card occupies one EX Controller telephony-card position and provides four analog FXS station ports with a published loop limit of up to 450 meters. When FXS or FXO cards are installed, Mitel requires one 50008234 DSP card per EX Controller chassis. Multiple FXS cards can be combined with PRI, FXO, and DSP modules to build a mixed IP, digital, and analog MiVoice Business solution.

Compatibility & Buying Information
Exact Part Number: This page is for Mitel part number 50008231, the standard 4-Port FXS card for the EX Controller platform.
Expansion Card Only: The 50008231 is an internal analog station module. It does not include the EX Controller, DSP card, MiVoice Business software, licenses, or analog endpoint devices.
Four Analog Station Ports: Each card provides four RJ-11 FXS interfaces for compatible analog station equipment.
FXS vs. FXO: FXS ports provide analog station service to endpoint devices. They should not be confused with FXO interfaces, which connect the EX Controller to external analog PSTN or PBX trunk lines.
450-Meter Loop Limit: Mitel identifies part number 50008231 as the standard four-port FXS card with a maximum published loop limit of 450 meters.
FXS-LP Is a Separate Card: Mitel separately lists part number 51309241 as the 4-Port FXS-LP card for the EX Controller. Customers with requirements beyond the published 450-meter loop specification of 50008231 should verify whether the FXS-LP model is the appropriate interface for their engineered installation.
DSP Card Required: Mitel requires one 50008234 DSP card per EX Controller chassis whenever FXS or FXO cards are installed. The DSP card consumes one of the eight available telephony-card positions.
Up to 28 Analog Ports: Mitel specifies EX Controller analog capacity of up to 28 total FXS or FXO ports. With one slot reserved for the required DSP card, an all-FXS configuration can use up to seven 50008231 cards for a total of 28 station ports.
Mixed Configurations: The EX Controller can combine supported FXS, FXO, PRI, and DSP cards. The final slot allocation should be engineered around required analog stations, analog trunks, digital trunks, and DSP resources.
MiVoice Business Programming: Analog FXS endpoints are created through User and Services Configuration and assigned the AnalogFXS device type and appropriate endpoint ID.
Australia Installation Note: Mitel specifies that in Australia, FXS wiring must not be bundled with network cabling and FXS / FXS-LP interfaces are for on-premises installation only.
Not an SMB Controller Card: The 50008231 is intended for the EX Controller platform and should not be confused with the separate FXS expansion hardware used by the Mitel SMB Controller.
Installation Safety: The EX Controller must be properly grounded and powered down before adding, removing, or replacing telephony cards. Proper ESD precautions should be used during installation and service.
Best Fit: Mitel 50008231 is ideal for MiVoice Business EX Controller deployments that need to integrate conventional analog station devices while maintaining a scalable mix of IP, analog, and digital telephony resources.
