USING THE MITEL IP PROGRAMMABLE KEY
MODULES (5324 IP PHONE ONLY)
IP Programmable Key Modules (PKM) add programmable keys to the 5324 IP phones. An IP
PKM Interface Module installs in the back of the 5324 IP Phone to allow the 12 or 48-button
IP PKM to connect to the IP phone without using an additional LAN port.
PKM keys can be programmed as feature keys, speed call keys, Direct Station Select (DSS)
keys, or line appearance keys. Each key has a Line Status Indicator that works the same way
as those on the associated telephone. The keys can be programmed through the telephone.
Note: Up to two 48-button PKMs can be attached for 96 additional keys.
