Mitel MC312AB SX-200 / SX-2000 / 3300 ICP telephone system PBX Card / Module

The Mitel MC312AB is a Peripheral Switch Control II Card. It manages switching and control functions for a Peripheral Node shelf, coordinating traffic between line/trunk cards and the SX-2000 control network. It belongs to Mitel’s SX-200/SX-2000/3300 ICP telephone system range, the long-running digital and IP PBX platform family widely deployed across small, medium and enterprise sites. Peripheral Switch Control cards of this kind coordinate every line and trunk card in a Peripheral Node shelf, so a spare is commonly held against a card failure taking the shelf offline. Tech-Star supplies this as genuine refurbished Mitel hardware, backed by a warranty (UK-based, shipped worldwide).
