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
