Mitel 50005105 SX-200 / SX-2000 / 3300 ICP telephone system PBX Card / Module

The Mitel 50005105 is the Analog Services Unit II for the 3300 ICP. It is a small chassis with two card slots that hangs off the controller and provides analogue services to the system: fitted with 24 port ONS cards it supports up to 48 analogue extensions, and the combination card gives 12 analogue extensions plus four loop start trunks. Cards are hot swappable. The unit is sold separately from its power supply, so check what is included with the item you are replacing.

The Mitel 3300 ICP is the IP communications platform that replaced the SX ranges, sold in CX, MX and MXe controller variants with add-on units for analogue and digital services. Peripheral shelves such as the Analog Services Unit and the Network Services Unit hang off the controller and carry the interface cards that terminate analogue phones, loop start trunks and digital circuits. The platform stayed in production long enough that a healthy secondary market exists for its controllers and service units.
