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, a destination code that uses that
line pool, 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 servic e.
M7100 and T7100 telephones
These sets do not have line buttons, therefore, they work slightly
differently from other Norstar and BST telephones.
• Where other telephones can require that you select a line button to
answer a call, on the these telephones you simply pick up the receiver.
• Where other telephones require you to select a line button to take a call
off hold, you press
³
on the these sets.
• Also on these sets, you can answer a second call by pressing
³
.
Your active call is put on hold and you are connected to the waiting
call. You can have no more than two calls at a time.
Tips -
When you make a call and the programmed route
is busy, you hear the expensive route warning tone. Your
telephones displays an expensive route warning. To avoid
using the normal, expensive route, release your call.
Overflow routing directs calls using different line pools.
Therefore, a call may be affected by different line filters
when it is handled by overflow routing.
