Calls on lines that ring but do not appear at a telephone are
presented at an intercom button.
You may be able to answer a call on a line that does not appear or
ring at your telephone. To pick up such a call, use Call Pickup, Call
Park, or Trunk Answer.
A telephone may have buttons assigned for lines 001 to 003, but
have only lines 001 and 002 programmed to ring as well. An
incoming call on any of the three lines causes a line button indicator
to flash, and the telephone can be used to answer the call. This is
especially useful for people who monitor other telephone lines, but
want only their own lines to ring.
Target line
A target line is used to route a call directly to a particular telephone
or group of telephones. Target lines are only used for incoming calls.
A single incoming line may provide connections to several different
target lines. This allows each person or department in the office to
have their own number without having a separate external line for
each number.
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

The maximum number of target lines
available in the fully expanded XC system is 192,
and 128 on a DR 2.0 system.
