Calculate number of trunks for time multiplexed space switch, Computer Engineering

Calculate the number of trunks that can be supported on a time multiplexed space switch given that, 32 channels are multiplexed in each stream, while the control memory access time is 100 ns and the bus switching and transferring time are 100 ns per transfer.

We know that N =125/ Mt

Here N = no. of incoming or outgoing trunks

M = sample per frame

t = switching time counting memory access time per inlet outlet pair.

For M = 32

The total switching time = 100 + 100 = 200 ns.

Thus, N = (125/200) x 32 x 10 = 20
