What is Time space switching?

Time space switching:- A time space (ts) switch takes the outputs of several time-division switches, for example, TSI switches and connects them as inputs as a space division switch. The effect of this paired arrangement is that packets can be swapped between different output lines.

If there were two outputs on a time division switch contending for the same output, the space-division switch delivers one of the two outputs to another output path. This arrangement also reduces the number of cross points required.
