Adding a PKM
A Programmable Key Module (PKM) provides the user with additional
personal keys for their telephone set. Four types are available: The Mitel
Networks Programmable Key Module 48 (PKM 48), the Mitel Networks
Programmable Key Module 12 (PKM 12), the Mitel Networks 5412
Programmable Key Module (5412 PKM), and the Mitel Networks 5448
Programmable Key Module (5448 PKM).
The PKM 48 provides SUPERSET 4025, SUPERSET 4125, and
SUPERSET 4150 telephone users with 48 additional personal keys; the
PKM 12 provides 12. Similarly, the 5448 PKM provides the Mitel
Networks 5220 IP Phone users with 48 additional personal keys, and the
5412 PKM provides 12. Up to two PKM 48 devices can be attached to a
SUPERSET telephone or attendant console. Up to two 5448 PKMs can
be attached to the 5220 IP Phone.
The telephone requires a SUPERSET Interface Module (SIM1 or SIM2)
to interface with a PKM. The SUPERSET Interface Module requires
programming through CDE to associate with the PKM. Similarly, the
5220 IP Phone requires a Mitel Networks 5422 Programmable Key
Module Interface Module (5422 PKM IM) to interface with a PKM.
For a SUPERSET Interface Module to work correctly with a SUPERSET
4000-series telephone, the SUPERSET 4000-series telephone must
have a Boot Revision of 4.2 or greater, and the SUPERSET 4000-series
telephone must be upgraded to the latest firmware available from the
system maintenance firmware download command.The SUPERSET
Interface Module also requires LIGHTWARE 17 Release 3.0 or greater
software.
A 5422 PKM IM requires LIGHTWARE 19 Release 3.1 UR 1 or greater
software.
Any connection of this set to an off-premise application, an
out of plant application, or to any other exposed plant
application may result in a safety hazard, and/or defective
operation, and/or equipment damage.
