This topic outlines general planning and setup considerations for networked systems, providing the information that you need in order to understand the sample private network scenarios presented in the next section of this chapter. Security issues are discussed in greater detail in Chapter 4, “Security,” and in Appendix A, “Customer Support Information.”

When systems are networked, follow these guidelines in order to make implementation of private network features go smoothly. These guidelines are based on the assumption that you plan to use the features listed below. Therefore, a coordinating system manager to oversee network -affectingchanges is recommended.

Non-local dial plan for intersystem calling among extensions located on different systems on the private network

ARS dialing via private networked trunks to allow users in one system to access the public switched telephone network (PSTN) facilities connected to one or more other networked systems

UDP routing for intersystem calling and ARS use of tandem trunks

Whether you are working alone to manage multiple systems in a private network or working with others who manage other systems in a private network, the overall planning considerations affect all networked systems.

The following topics do not explain programming procedures or details of all system features that the sections reference. For detailed feature information, see the Feature Reference. For detailed programming procedures, see System Programming.

Non-Local Dial Plan

2

System managers in a private network create non-local dial plans so that local system users can call extensions in remote networked systems. This intersystem dialing is transparent to system users; they dial these calls as though they were intercom calls, using System Access (SA) or Shared System Access (SSA) buttons. Chapter 5, “Network Management,” includes information about such parameters as the valid number of digits, extension ranges, and patterns for programming non-local dial plans and routes.

A non-local dial plan consists of extension numbers for the following:

Stations

Adjuncts

Listed Directory Number (LDN)

Remote Access
