Programmable Key Module 48
The Programmable Key Module 48 (PKM48) provides 48 additional feature keys for
SUPERSET 4025, SUPERSET 4125, and SUPERSET 4150 telephones. Each feature key has
a Line Status Indicator that behaves the same way as those on SUPERSET 4000 series
telephones.
The PKM48 connects to the PKM interface on the SIM1. A second PKM48 can connect to the
first to provide for 96 additional feature keys for the SUPERSET 4025 and SUPERSET 4150
telephones. You cannot connect a PKM48 to an
AIM device.
For installation instructions, see the SX-2000 Install Peripherals section of the Technical
Documentation CD-ROM.
