Line Pools; Overflow Call Routing; M7100 Telephone - Northern Telecom Compact ICS 4.0 Manual

Line pools

A line pool allows each telephone access to external lines from
a group (or pool) of external lines. You can access such lines
by pressing an intercom button and entering a line pool access
code or by pressing a memory button programmed with the
line pool feature code and a line pool access code.

Overflow call routing

If a call comes in for a target line that is busy, Norstar routes
the call to the prime telephone for that target line. If there is no
prime telephone assigned to the target line or if a call cannot
be directed to a target line, the call goes to the prime telephone
for the external line used.
Overflow routing for incoming calls is used with the Routing
Service programmed by your installer. A Service must be
active for overflow routing to be in effect. Overflow routing is
not available in normal service.

M7100 telephone

Because the M7100 telephone does not have line buttons, it
sometimes works slightly differently from other Norstar
telephones. Where other telephones can require that you select
a line button to answer a call, on the M7100 telephone you
simply pick up the receiver. Where other telephones require
˙
you to select a line button to take a call off hold, you press
˙
On M7100 telephones, you can answer a second call by
pressing
