Inside Macintosh: Telephony /

Chapter 2 - Telephone Terminals

This chapter describes telephone terminals, hardware devices that provide a physical interface between a Macintosh computer and a telephone network switch. For example, an ISDN card connected to a private branch exchange is a telephone terminal.

To use this chapter, you should already be familiar with the information presented in the chapter "Introduction to Telephony on the Macintosh" earlier in this book. You need to initialize the Telephone Manager and configure any required tools before you can open and use a telephone terminal. Once a terminal is open, your application can send commands through the Telephone Manager and telephone tools to the device drivers and terminal hardware.

This chapter describes the data structures and functions you can use to open and manage telephone terminals. See the chapter "Telephone Manager Messages" for a description of the telephone terminal messages that the Telephone Manager can send to your application. See the chapter "Telephone Tools" for a description of the telephone terminal messages a tool can send to the Telephone Manager.
