Abstract

338,127. Automatic Telephone Manufacturing Co., Ltd., and Gillings, C. Aug. 9, 1929. Divided on 338,125. Drawings to Specification. Automatic exchange metering systems. - An extra digit indicative of the zone of the wanted party is sent out from a register-translator prior to the ordinary routing member and is recorded at the first code selector either on an associated minor switch or on a set of relays selectively operated by a preliminary vertical motion of the selector itself. The invention is described with reference to a satellite system identical with that described in Specification 338,125 in which calls from a satellite subscriber are set up under the control of register-translators at the main exchange, metering impulses in accordance with the extra digit being sent back from the main exchange to the satellite over a two-conductor trunk at the end of conversation. Specification 233,007 also is referred to.
