0	About the System	2

This chapter provides a general overview that introduces all of the major aspects of the system and its operation, including:

■Trunks

■Modes of operation

■System components

■Features

■Applications

■Programming the system

■System capacities

■Auxiliary components

■Data communications capabilities

More information about specific system topics is included throughout the guide.

The Feature Reference and System Programming provide detailed information.

Many of the principles of telephone communications have not changed since Alexander Graham Bell made the first phone call in 1876. Because learning about these concepts helps explain how the system works, this chapter begins with some background information about telephone communications. For a more

detailed history and description, see Appendix B, ‘About‘ Telecommunications’’.

If you are already familiar with the concepts described in this chapter, you can skip the chapter.
