Description Telephones have multiple
buttons (or keys) labeled
with telephone numbers.
Every button corresponds
directly to an outside line.
Different buttons (ICOM
buttons) are used for
inside calls.
Outside trunks are
grouped in pools for
shared use; the system
automatically selects an
available outside trunk.
People use the same
button to make both
inside and outside calls.
Used when the system
(called the local system) is
connected to a larger PBX
or Centrex system (called
the host system). One
outside line (a prime line)
is assigned to each
telephone. The host
system provides the
interface to outside lines
and some features.
