About PKMs
A PKM (Programmable Key Module) provides the telephone user with additional personal keys.
The additional personal keys can be programmed as Feature keys or Line keys. See List of
Feature Keys and List of Line Keys. The default setting is a Speed Dial key.
SUPERSET Telephone Support
There are three types: the PKM, the PKM48, and the PKM12. The PKM provides 30 extra keys,
the PKM48 provides 48, and the PKM12 provides 12 extra keys.
- The PKM provides additional personal keys for SUPERSET 410, SUPERSET 420,
and SUPERSET 430 telephones.
- The PKM48 and PKM12 provide additional personal keys for SUPERSET 4025,
SUPERSET 4125, and SUPERSET 4150 telephones.
5020 IP Phone Support
- 5410 Programmable Key Module (PKM) provides 12 additional personal keys.
- 5415 Programmable Key Module provides 48 additional keys. A 5020 IP phone can
support a maximum of two 5415 PKMs, which together provide a total of 96 additional
keys.
5220 IP Phone Support
- 5412 Programmable Key Module (PKM) provides 12 additional personal keys.
- 5448 Programmable Key Module provides 48 additional keys. A 5220 IP Phone can
support a maximum of two 5448 PKMs, which together provide a total of 96 additional
keys.
Note
Make sure that you know the type of PKM connected before you program the PKM keys. For example, the
SX-200 system does not recognize the difference between a PKM48 and a PKM12 and will therefore not
provide an error message if you program more than 12 keys for a PKM12.
About PKM Interface Units
A PKM Interface Unit (DSS/BLF Interface Unit) is required when a PKM48 is associated with
an attendant console. Not all attendant console require this unit. The SUPERCONSOLE 1000
attendant consoles with PN 9189-000-300 and PN 9189-000-301 can connect directly to the
PKM48.
A PKM Interface Unit has its own circuit address and is identified in the Phone Data window.
The keys on the PKM48 attached to a PKM Interface Unit can only be programmed as DSS/BLF
keys. See Program Line Keys. You are not able to add, delete, or move the PKM Interface Unit.
