Question

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

Answer 1

Answer:

which standard is this

Answer 2

Answer:

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
