2. Time-slot interchange - Wikipedia

   en.wikipedia.org/wiki/Time-Slot_Interchange

   In packet-switching networks, a time-slot interchange switch is often combined with two space-division switches to implement small network switches. In telephone switches, time-slot interchange switches usually form the outer layer of the switching fabric at a central office's switch.

3. Nonblocking minimal spanning switch - Wikipedia

   en.wikipedia.org/wiki/Nonblocking_minimal...

   time-division multiplexers each have a memory which is read in a fixed order and written in a programmable order (or vice versa). This type of switch permutes time-slots in a time-division multiplexed signal that goes to the space-division multiplexers in its adjacent layers. Design advantage: Time-division switches have only one input and ...

4. Space-division multiple access - Wikipedia

   en.wikipedia.org/wiki/Space-division_multiple_access

   Space-division multiple access (SDMA) is a channel access method based on creating parallel spatial pipes (focused signal beams) using advanced antenna technology next to higher capacity pipes through spatial multiplexing and/or diversity, by which it is able to offer superior performance in radio multiple access communication systems (where multiple users may need to use the communication ...

5. Telephone exchange - Wikipedia

   en.wikipedia.org/wiki/Telephone_exchange

   Traditional telephone switches connected physical circuits (e.g., wire pairs) while modern telephone switches use a combination of space-and time-division switching. In other words, each voice channel is represented by a time slot (say 1 or 2) on a physical wire pair (A or B). In order to connect two voice channels (say A1 and B2) together, the ...

6. Time-division multiplexing - Wikipedia

   en.wikipedia.org/wiki/Time-division_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 according to agreed rules, e.g. with each transmitter working in turn.

8. Spatial multiplexing - Wikipedia

   en.wikipedia.org/wiki/Spatial_multiplexing

   Spatial multiplexing or space-division multiplexing (SM, SDM or SMX) is a multiplexing technique in MIMO wireless communication, fiber-optic communication and other communications technologies used to transmit independent channels separated in space.

9. Time-driven switching - Wikipedia

   en.wikipedia.org/wiki/Time-driven_switching

   In telecommunication and computer networking, time-driven switching (TDS) is a node by node time variant implementation of circuit switching, where the propagating datagram is shorter in space than the distance between source and destination. With TDS it is no longer necessary to own a complete circuit between source and destination, but only ...
