2. Time-slot interchange - Wikipedia

   en.wikipedia.org/wiki/Time-Slot_Interchange

   In a time-slot interchange (TSI) switch, two memory accesses are required for each connection (one to read and one to store). Let T be the time to access the memory. Therefore, for a connection, 2T time will be taken to access the memory. If there are n connections and t is the operation time for n lines, then t=2nT which gives n=t/2T

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. 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.

5. Stored program control - Wikipedia

   SPC technology using analog switching matrices was largely phased out in the 1980s and had disappeared from most modern networks by the late 1990s. The addition of time-division multiplexing (TDM) decreased subsystem sizes and dramatically increased the capacity of the telephone network. By the 1980s, SPC technology dominated the ...

7. 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 ...

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 ...
