Mitel Superset™ 4000 Programmable Key Expansion Modules

Expand Superset telephone and console functionality with expansion modules.

Adding 12, 48 or even 96 more programmable keys to the Mitel Superset 4000 series telephone sets and consoles is simple with the Superset programmable key module and interface module. The interface module also allows for the simultaneous connection and use of a compatible Superset 4000 series telephone and an analog telephone or other device on a single DNIC port, saving valuable system ports for future expansion or alternate use.
