What is Time-division (TDM) Multiplexing?


Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern. This form of signal multiplexing was developed in telecommunications for telegraphy systems in the late 1800s, but found its most common application in digital telephony in the second half of the 20th century. 


The U.S. General Services Administration (GSA) placed a March 2020 deadline to replace TDM-based networks. If you're still looking to move away from systems based on time-division multiplexing, discover how Mitel can help you migrate to the cloud and move your communications to software-defined wide area networks (SD-WAN) - the newer technology business-critical communications functions are based on.
