digital representation of sampled analog signals

thumb|250px|Multiple low data rate signals are multiplexed over a single high-data-rate link, then demultiplexed at the other end.

channel access method for radio communication, allowing many transmitters to send information over one channel using spread spectrum technology and a special coding scheme; used in GPS, cdmaOne, CDMA2000, UMTS etc

technology used in telecommunications networks

The E-carrier is a member of the series of carrier systems developed for digital transmission of many simultaneous telephone calls by time-division multiplexing. The European Conference of Postal and Telecommunications Administrations (CEPT) originally standardised the E-carrier system, which revised and improved the earlier American T-carrier technology, and this has now been adopted by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T). It was widely used in almost all countries outside the US, Canada, and Japan. E-carrier deployments have steadily bee
