Abstract
523,443. Automatic exchange systems. POLLAK, J. E. (Associated Telephone & Telegraph Co.). Jan. 4, 1939, No. 27777. Divided out of 516,348. Drawings to Specification. [Class 40 (iv)] The system is identical with that described in Specification 516,348, but the claims are directed to the control switch (RS6) which determines the nature of the operations to be performed by the register-translator in setting up calls to different destination exchanges or in setting up different kinds of call. A different bank or portion of a bank of the switch is selected in accordance with the kind of connection required. The operations determined by the switch include the kind of metering (ordinary or ticketing); selection of the quality of junctions; with or without repeaters; the routing of the call; the transmission of the calling number; code or numerical transmission of digits; transmission of the calling number for ticketing, call-indicating or faulty line notification; signalling the desire of a calling party for information, e.g., of the charge of a call ; the stages of the connection at which certain operations are performed, e.g., release of the register-translator.
