78 / Line pools

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 MICS system can have 15 non-PRI line pools and a
maximum of four PRI line pools, depending on the hardware
and profile configuration for your system. A telephone can be
programmed to access any number of line pools. 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.
A line pool access code is a number you dial to get a non-PRI
line pool. The access code can be up to four digits long. Your
installer or customer service representative programs the line
pool access codes and gives each telephone access to a line
pool.
PRI line pools are accessed using destination codes.
Destination codes differ from line pool codes, in that PRI line
pools are assigned to specific routes that are then assigned a
destination code. Destination codes can also be assigned to
schedules, so that different pools are used at different times of
the day.
Everyone in the office should have a list of the line pool access
codes and destination codes for the line pools their telephones
can use.
