Dynamic synchronous transfer mode (DTM) is an optical networking technology standardized by the European Telecommunications Standards Institute (ETSI) in 2001 beginning with specification ETSI ES 201 803-1.
DTM is a time-division multiplexing and a circuit-switching network technology that combines switching and transport.
The DTM architecture was conceived in 1985 and developed at the Royal Institute of Technology (KTH) in Sweden.
[3] The research team was split into two spin-off companies, reflecting two different approaches to use the technology.
One of these companies remains active in the field and delivers commercial products based on the DTM technology.
