Description
Nortel Meridian QPC444A Conference Card PBX Telephone System Module
The Nortel Meridian QPC444A is a conference card designed for use in Nortel Meridian PBX telephone systems. Conference cards of this type provide the switching and DSP resources required to bridge multiple telephone extensions into a single conference call within the PBX chassis, offloading that function from the main call processing hardware.

Applications
The Nortel Meridian PBX platform was one of the most widely deployed enterprise telephone systems from the 1980s through the 2000s, found in corporate offices, government facilities, universities, and hospitals. Conference cards like the QPC444A slot into the Meridian chassis and provide dedicated hardware conference bridging — allowing multiple internal and external lines to be joined into a multi-party call without tying up the system's general switching resources. These cards are still sought after as spare or replacement modules by organizations that continue to operate legacy Nortel Meridian systems, as well as by telecom technicians supporting those installations.
