Adding a PKM
A Programmable Key Module (PKM) provide the user with additional
personal keys for their telephone set. Two types are available: The Mitel
Networks Programmable Key Module 48 (PKM 48) and the Mitel
Networks Programmable Key Module 12 (PKM 12).
The PKM 48 provides SUPERSET 4025, SUPERSET 4125, and the
SUPERSET 4150 telephone users with 48 additional personal keys; the
PKM 12 provides 12. The programming for both are the same. Up to two
PKM 48 devices can be attached to the telephone or attendant console.
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.
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.
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.
The PKM 12 and the PKM 48 are the only programmable key
modules qualified by Mitel Networks for connection to
SUPERSET 4000-series telephones.
The PKM 12 is not designed to connect to a PKM 48.
