Explain 100 line exchange with selector finder.

Design: In place of 100 two-motion selectors as in the case of Design 3, suppose we consider only 24 two-motion selectors. When, 24 simultaneous calls can be put by the switch. The 24 two-motion selectors are shared through all the hundred users. The equivalent outlets of the two-motion selectors are commoned as in the earlier case. This is implicitly assumed now that the average peak-hour traffic is 24 simultaneous calls. Classically, a 24-outlet uniselector is utilized as a selector hunter.

All of the 24 outlets is connected to one two-motion selector. Therefore, a subscriber has access to all the 24 two-motion selectors in the system. The equivalent outlets of all the selector hunters are commoned and therefore, all subscribers have access to all the two-motion selectors. Such scheme is demonstrated in figure. The call establishment into this scheme takes place within two steps. Initially, when the subscriber lifts his receiver handset, his uni selector hunts through the contact positions and seizes a free two-motion selector. At the subsequent step, the two-motion selector responds to the dial pulses for suitable connection. The design parameters of such system are:
