When assigning lines to line pools, consider your network
configuration. You may be able to create a unified dialing
plan by assigning lines to the same location to the same line
pool on each of your systems. For example, if system A and
system B each have tie lines to system C, assign the tie lines to
pool D on each of the systems.
If you plan to program the prime line as I/C (intercom) for
some telephones, you may wish to assign loop start lines to the
first line pool. Remember that when the system searches for an
outgoing line, it begins at line pool A and chooses the first
available line.
Assigning a single E&M trunk to a line pool allows features
like Ring Again to help manage access to a shared resource.
You cannot assign target lines (157-248/380) to a line pool.
