5.7 Design an STS switch for 128 primary TDM signals of the CCITT hierarchy (30 voice channels per input). Blocking should be less than 0.002 and the loading is 0.2 erlang per channel. How many time slot interchange modules are needed? What is the complexity of the switch? Repeat Problem 5.7 for a TST design.
