The
central hardware component in
the
system. The KSU
has its own processor and
memory, and provides a
physical point of connection for
the various types of devices,
telephones, and expansion
modules used in The
KSU can function on its own as
a basic system (with 24
telephones and 8 external
lines), or with the addition of a
Trunk Module (TM) that
supports more external lines, or
a Station Module (SM) that
supports more
telephones.

voice or data connection
between one telephone (or
other device) and another.

The sub-heading
in Administration programming
that allows you to assign names

Line Pool:
A group of lines
used for making external calls.
Line Pools provide an efficient
way of giving a telephone
access to external lines without
taking up many line buttons. A
line is assigned to be a member
of a Line Pool by your Customer
Service representative.
Line Pool access code:
A
number that identifies a Line
Pool. Line Pool access codes
are assigned by your Customer
Service representative.
Line Profile:
A feature you can
use to review the settings .
programmed to lines by the
Customer Service
representative and by
Administration programming.
The settings cannot be changed
with this feature. Line profile is
available only on and
M7324 Telephones.
Line Redirection:
A feature
that allows you to redirect all
calls on an incoming line to a
destination outside the
system. Once a line is
redirected it cannot be
answered within the
system. The system may be set
up to give a brief ring when a
call comes in on a redirected
line. This feature differs from
Call Forward in two ways. It
redirects only external calls (not
internal calls) and it redirects
calls to destinations outside the
system. Call forward redirects
calls only to destinations inside
the system. See Call
Forward and Redirect Ring.
