Telecom

Modem

The word modem is a composite of the words modulator and demodulator.

A modem enables communication between digital devices and access to the Internet. Modems connect a computer to an analog phone (acoustic modems), a phone line or a cable connection. By converting digital signals to analog signals and converting analog signals back into digital signals, modems enable the transfer of digital data over analog telecom systems.

The use of modems in Switzerland has dwindled in favor of Internet routers as digital telecom networks have largely replaced analog phone lines. Most Swiss broadband services provide their customers with Internet routers by default.
