Editing Time-division multiplexing (section)

==Application examples==
* The [[plesiochronous digital hierarchy]] (PDH) system, also known as the [[Pulse-code modulation|PCM]] system, for digital transmission of several telephone calls over the same four-wire copper cable ([[T-carrier]] or [[E-carrier]]) or fiber in the circuit-switched digital telephone network
* The [[synchronous optical networking|synchronous digital hierarchy (SDH)/synchronous optical networking (SONET)]] network transmission standards that have replaced PDH
* The [[Basic Rate Interface]] and [[Primary Rate Interface]] for the [[Integrated Services Digital Network]] (ISDN)
* The [[RIFF (File format)|RIFF]] (WAV) audio standard interleaves left and right stereo signals on a per-sample basis

TDM can be further extended into the [[time-division multiple access]] (TDMA) scheme, where several stations connected to the same physical medium, for example sharing the same [[Frequency-division multiplexing|frequency]] channel, can communicate. Application examples include:
* The [[Global system for mobile communications|GSM]] telephone system
* The Tactical Data Links [[Link 16]] and [[Link 22]]
