Abstract

554,091. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. July 10, 1942, No. 9605. Convention date, April 12, 1941. [Class 40 (iv)] In a line-identifying system, each line has a discharge tube with a priming anode and a number of discharge anodes, one for each digit of the line designation. In the system described, the first digit indicates whether the station is a " tip " or " ring " station on a party line, the next four, the number, the next, the class of service to which the line is entitled and the last, the office. When.an identification is to be made, a relay CONN connects the discharge anodes to the upper terminals of the corresponding relays in a set of registers and energizes a relay ST which connects battery to the lower terminals of all the register relays and also to the lower talking wire. If the calling station is that of a " tip " party, a relay TP operates to connect up (Continued on opposite page)
