Trunk lines and Target lines
In order to configure a
system, you need to distinguish
between trunks and target lines.
A
trunk
is a physical line numbered from 001 to
(in a
fully expanded system).
A
target
line is a ‘virtual’ communication path between an
external caller and a
telephone (or other
device). This path is established on the basis of digits
received from an incoming trunk. Target lines number from
081 to 184 (in a fully expanded
system).
Having target lines, independent of the physical lines, makes it
possible to have many target lines for a few physical trunks.
Telephones can be configured to have an appearance of any
type of line (including target lines). Calls may be placed on all
lines except target lines.
See the description of Line Pool programming under the
Line
setting (in
1.
Data, Line data)
for the recommended assignments to line pools.
