Key Expansion Module (KEM)
IP Phone Key Expansion Module description
Nortel IP Phone Key Expansion Module (KEM) is a hardware component
that connects to an IP Phone to expand the number of fixed line and
feature keys available to the phone. The number of keys that are available
is determined by the Communication Server (CS2000/CS2100) to which
the IP Phone or KEM is connected, and not the devices. When KEM
is used with the Centrex IP Client Manager (CICM), only 22 keys are
available, despite there being 24 physical keys on the KEM.
Keys on the KEM are displayed in two columns of 12 keys, with one
column on each side of a central liquid crystal display (LCD) screen. When
deployed with CICM, the top two keys of each column are not used. See
Figure 1 "IP Phone Key Expansion Module" (page 8)
.
When a KEM is installed on an IP Phone, the IP Phone controls the keys
of the KEM just as it does its native keys.
