Modem Connections and Operation Overview

This chapter covers the following topics:

Wide-area communication takes advantage of the existing PSTN for data transfer by converting digital signals into analog signals and vice versa for transmission over the PSTN. The device used to accomplish such conversion is called a modem (short for modulator/demodulator).

This chapter concentrates on the following modem-related topics:

  • A typical modem connection

  • DTE-to-DTE wiring

  • Data compression and error control

  • Configuring the modem (DCE)
