Nortel NTDK20AB: Option 11C System Core card for the Meridian 1/CS1000 Option 11C PBX cabinet, carrying call-processing software and system timing.

The Nortel NTDK20AB is an Option 11C System Core card, the central processing card for the Meridian 1/CS1000 Option 11C small-to-medium enterprise PBX cabinet. It carries the system’s call-processing software, timing reference and control logic, coordinating the network, peripheral and power shelves that make up an Option 11C chassis.

Nortel Meridian 1 and CS1000 systems remain in service across offices, hospitals, universities and public sector sites. Manufacturer support ended with the move to Avaya, so secondary-market cards are now the normal route to keeping one of these switches running. Confirm your exact Option 11C release and cabinet configuration before ordering, as core card revisions are not universally interchangeable.
