Abstract

A communication line selection system having multi-selector switches for interconnecting call and call lines, said multi-selector switches being grouped into a number of sequential selector steps including a primary step and a terminal step, common equipment including power means and means and recorder, associated with the multi-selector switches of said primary step, means for connecting said lines to the outputs of the multi-selector switches of said terminal step, means for connecting the outputs of the multi-selector switches of a previous sequential passage to the outputs of the multi-selector switches of the next sequential step comprising each of said multi-selector switches and selection levels, said levels of divided selection being determined, recorder-finder means including said divided selection levels of said switches primary multiselectors, for selectively interconnecting said power means and said recorder means and means including said selection levels divided into the multi-selector switches of said terminal step for connecting certain of said outputs to only a portion of said selectors.
