Q. How time slot interchange switch works in time multiplexed time switching, Elucidate using schematic.

Ans:

Switches for which inlets and outlets are trunks that carry time division multiplexed data streams. Such switches are known as time multiplexed switches. A time multiplexed time division space switch is displayed in figure. There are N incoming trunks and N outgoing trunks, each carrying a time division multiplexed stream of M samples per frame. Every frame is of 125-µs time duration. In one frame time, a total of MN speech samples have to be switched. One sample duration, 125/M microseconds is generally referred to as a time slot. In one time slot, N samples are switched. Figuredemonstrates an output-controlled switch. Output is cyclically scanned. There is a 1-to-M relationship between outlets and control memory locations, which impliesthat there are M locations in the control memory corresponding to each outlet.

Control memory has MN words. If we view the control memory as M blocks of N words each, a location address can be specified in a two dimensional form(i,j),where i is the block address and j is the word within the block. We have 1< i < M and 1
