This guide includes five chapters:

■Chapter 1, Introduction. This chapter provides a grounding in the basic terminology and concepts that you must understand in order to manage a networked system.

■Chapter 2, Call-Handling Scenarios. Studies several sample network configurations, demonstrating how the systems are set up for networking, how calls are made and received, and the advantages and disadvantages of each configuration.

■Chapter 3, Feature Interactions. Describes the ways that system features work in networks.

■Chapter 4, Security. Discusses security issues and considerations.

■Chapter 5, Network Management. Summarizes programming procedures for setting up and modifying network operations.

■Chapter 6, Troubleshooting. Describes common problems that you may encounter, their possible causes, and their solutions.

This guide is intended as a companion to the Release 6.1 Feature Reference, System Programming, and System Manager’s Guide, which explain many system features and procedures in greater detail. Because private networks leverage existing communications system features as well as introducing new ones, this guide focuses not on a thorough discussion of system management and system features but rather on how they apply to private networks. “Related Documents” on page xxx provides a complete list of system documentation together with ordering information.

Terms and Conventions Used 0

The terms described here are used in preference to other, equally acceptable terms for describing communications systems.

Lines, Trunks, and Facilities

Facility is a general term that designates a communications path between a telephone system and the telephone company central office. Technically, a trunk connects a switch to a switch, for example, the MERLIN LEGEND Communications System to the central office. Technically, a line is a loop-start facility or a communications path that does not connect switches, for example, an intercom line or a Centrex line. However, in actual usage, the terms line and trunk are often applied interchangeably. In this guide, we use lines/trunks and line/trunk
