Design : Rather than 100 two-motion selectors as in the case of Design 3, let's consider only 24 two-motion selectors. In the case 24 simultaneous calls can be put through the switch. 24 two-motion selectors are shared by all the hundred users. Corresponding outlets of the two-motion selectors are commoned as in the previous case. It's implicitly assumed here that average peak-hour traffic is 24 simultaneous calls. Normally a 24-outlet Uni-selector is used as a selector hunter. Each of 24 outlets is connected to one two-motion selector. Hence a subscriber has access to all the 24 two-motion selectors in system. Corresponding outlets of all the selector hunters are commoned and hence all subscribers have access to all the two-motion selectors. This scheme is demonstrated in figure. Call establishment in this scheme takes place in 2 steps. Firstly, when subscriberlifts his receiver handset, his Uni-selector hunts through the contact positions and seizes a free two-motion selector. At the subsequent step, two-motion selector responds to dial pulses for appropriate connection. Design parameters of this system are:
