Release 6.0 Enhancements (February, 1998)
the extension ranges of remote networked switches to create a non-local
dial plan. This programming does not actually affect numbering on the
remote system. To correctly set up systems for transparent calling
among non-local dial plan extensions, the system manager assigns
networking tie and/or PRI tandem trunks to pools. Then he or she
programs as many as 20 patterns, associates with routes, Facility
Restriction Levels (FRLs), digit absorption, and digit prepending. This
allows ARS-like routing of non-local dial plan calls. In addition, system
managers can control whether calling name, calling number, or both are
shown at MLX display telephone for incoming calls across PRI tandem
trunks.
■ Toll Savings. Private networked trunks allow you to realize significant
cost savings on toll calls by performing tandem switching in the following
two ways:
— Callers on a local system can reach the PSTN via outside trunks
connected to other systems in a private network, avoiding toll charges
or substantially decreasing the cost of toll calls. For example, if you
are in Cincinnati and another site in your company is in Dallas, you
can make a call to a number in the Dallas local calling area over your
private network, decreasing toll costs.
— In addition, organizations use private networked trunks to make calls
between networked systems, which may be geographically distant
from one another. Using the example above, from your office in
Cincinnati you can dial an extension at a sister site in Dallas, just as
you would dial an extension on your own local system, without a
costly long-distance phone call. You simply dial the extension
number.
■ Service Cost Savings. In addition to toll call savings, there are two other
ways that organizations can save on service costs incurred from
telecommunications providers that provide PSTN access:
— You order a point-to-point T1 circuit from a service provider, then use
system programming to set it up for tandem PRI services. As
necessary, a service provider provides amplification for PRI tandem
