The
following
features are available
for
the
entire
Norstar
system.
Disconnect supervision
When
Disconnect
Supervision is assigned
to
a line, the Norstar
system
monitors
it
to detect
if
an
external
caller hangs
up.
This
allows the system
to release the
line
for
other
uses.
Your
installer
or
customer
service representative assigns
disconnect
supervision.
Incoming line groups
Lines can
be assigned
to
an
incoming line
group
to
provide line
concentration
for incoming
calls.
You
can
then assign the
incoming
line
group to
appear at
a telephone rather
than each individual line.
This
frees up
memory
buttons for
programming
features
or autodial
numbers.
You
can assign the
same
incoming
line group
to several telephones.
You answer
calls
on
an incoming
li
ne
group in the
same
way
as
you
answer calls
on a
line.
Internal numbers
Each telephone in
the
Norstar system
has
its
own
internal
number
.
The
length
of internal numbers
in
your system
can
be from two
to
seven
digits. All numbers
in
your system
are
the
same
length.
Your
installer
or customer service representative sets
the
length of
internal
numbers
(also called
the
ON
length).
To
find
out
your
internal
number,
use
the
Button Inquiry feature
(
!
Feature
I
EJ@]
) on an
intercom
button.
On
the
M7100
telephone,
Button
Inquiry shows
your internal
number followed
by
the
function
assigned
to
your single-memory button
.
Line assignment
Any of the
lines
in
your system
can be
assigned
to
any
of your
telephones.
Your
installer or
customer
service representative
assigns lines
to telephones
in Configuration programming
.
