Abstract

339,600. Automatic Telephone Manufacturing Co., Ltd., and Gillings, C. Sept. 5, 1929. Divided on 339,345. Drawings to Specification. Automatic exchange metering systems.-A discriminating selector at a satellite exchange, in response to one or more digits transmitted from a sub-satellite, determines' whether the connection is to be completed over the selector wipers or over a junction to the main exchange and at the end of the conversation controls the selection of one of a series of metering cams whereby the appropriate number of metering impulses is transmitted back to the sub-satellite. The selector may drop back after the first digit and respond again to the second, the selection of the appropriate metering cam being determined by the position which the selector occupies during conversation. The invention is described with reference to a system identical with that described in Specification 339,345.
