Mitel 4 Port FXO for EX Cont - 50008232
The Mitel 50008232 is a four-port FXO analog trunk interface card designed specifically for the Mitel EX Controller platform running MiVoice Business. It provides four RJ-11 FXO connections for integrating traditional analog PSTN or PBX trunk lines with an EX Controller, allowing organizations to retain conventional analog carrier connectivity alongside modern IP and SIP communications.
Each 50008232 card occupies one EX Controller telephony-card position and provides four analog FXO trunks. When FXS or FXO cards are used, Mitel requires one 50008234 DSP card per controller chassis. The modular EX Controller architecture supports mixed PRI, FXO, FXS, and DSP configurations, with total analog capacity of up to 28 FXS/FXO ports depending on the installed card combination.

Compatibility & Buying Information
Exact Part Number: This page is for Mitel part number 50008232, the standard 4-Port FXO card for the EX Controller platform.
Expansion Card Only: The 50008232 is an internal analog trunk module. It does not include the EX Controller, DSP card, MiVoice Business software, licenses, analog carrier service, or other telephony cards.
Four Analog Trunks: Each card provides four RJ-11 FXO ports for connecting compatible PSTN / central-office analog lines or compatible analog PBX trunk interfaces.
FXO vs. FXS: FXO ports connect the EX Controller to external analog telephone-company or PBX lines. FXS cards perform the opposite function by providing analog station service to endpoints such as analog phones and supported fax equipment.
DSP Card Required: Mitel requires one 50008234 DSP card per EX Controller chassis when any FXS or FXO card is installed. The DSP card occupies one of the eight available telephony-card positions.
Up to 28 Analog Ports: Mitel specifies EX Controller analog capacity of up to 28 FXS or FXO ports. Because an analog configuration requires one slot for the DSP card, an all-FXO configuration can use up to seven 50008232 cards for 28 analog trunk ports.
Mixed Configurations: FXO cards can be combined with supported FXS, PRI, and DSP cards. Available analog and digital trunk capacity depends on how the controller's eight telephony-card positions are allocated.
North American Configuration: MiVoice Business includes an FXO configuration script for North American analog trunks using loaded coils as well as a default configuration for non-loaded-coil lines. Dial Tone Detection Mode can also be disabled when required by the deployment.
Australia Uses a Different SKU: Mitel lists part number 50008353 as the Australia-specific FXO card for the EX Controller. Customers deploying in Australia should use the appropriate regional card rather than assuming 50008232 is interchangeable.
Not an SMBC Card: The 50008232 is designed for the EX Controller. It should not be confused with Mitel 50008255, the separate 4-Port FXO trunk card used by the SMB Controller.
Not a SIP Trunk License: This product provides physical analog FXO interfaces. SIP trunks, SIP carrier services, and associated MiVoice Business licensing are separate components.
Card Replacement: Mitel recommends replacing a failed FXO card with the same type of card in the same slot whenever possible. Moving a telephony card or changing a slot to another card type can cause the existing slot configuration to be lost and require reprogramming.
Installation Safety: The EX Controller must be properly grounded and powered down before adding, removing, or replacing telephony cards. Appropriate ESD protection should be used during service.
Best Fit: Mitel 50008232 is ideal for MiVoice Business EX Controller deployments that need traditional analog PSTN trunks, backup copper lines, analog PBX interconnection, or hybrid analog and SIP carrier connectivity.
