Norstar-PLUS Modular ICS 2.0 System Coordinator Guide P0857846 Issue 02
Choosing a line using a line button
You have one line button for each line assigned to your telephone.
Press the line button to select the line you want to answer or use to
make a call. Having several line buttons allows you immediate
access to more than one line.
The M7100 telephone has two intercom paths which are used
instead of line buttons to answer and make calls. Each M7100 can
be assigned two lines. You can press
˙ to switch between
two calls, one active and one on hold.
Line pools
A line pool is a group of external lines that can be shared by many
telephones. You can use a line in a line pool to make an external
call.
The Norstar Modular ICS system can have 15 line pools, and a
telephone can be programmed to access any number of them.
A line pool access code is a number you dial to get a line pool. The
access code can be up to four digits long. You can have several
different line pools for your system, each one giving you access to a
different set of external lines. It is one way of sharing lines across
telephones in a system.
The call you are trying to make has been
restricted in programming. A possible reason
is time-of-day restrictions on certain calls.
