Abstract

PURPOSE:To simplify line opening and test, by arranging time division multiple lines and timing signal lines in a matrix and by providing a connecting means at each intersection to store a line interface circuit. CONSTITUTION:Time division multiple lines 0-m in the logitudinal dirdction and timing signal lines 0-n from a timing circuit T for signal supply which indicate signal positions on multiple lines in the transverse direction are arranged in a matrix, and connecting means for a service line, a power source, a call signal, and various control lines which a line interface circuit requires is arranged at intersections to constitute a channel board SPB. Line opening and transfer are performed by attaching and detaching a subscriber's circuit or the line interface circuit correspondingly to connector terminals of the channel board SPB. If the line interface circuit is provided with a receiving terminal for test, the test operation is simplified.
