Abstract

839,939. Automatic exchange systems. SIEMENS & HALSKE A.G. May 22, 1958 [May 22, 1957], No. 16537/58. Class 40 (4). Metering changes are recorded by storing the numbers of subscribers subject to such changes, the storage of said numbers being effected within the minimum period of time which can elapse between successive metering impulses. As described, there is one magnetic recording device for the exchange. When a metering impulse appears at one of the first group selectors, say GW1, a relay Z21 energizes temporarily to energize relay Z3 in the calling subscriber's circuit TS so causing impulses representative of the subscriber's number to be applied over wires T, H, Z, E to the recording device RE. The impulses are coded and the beginning of each code signal is indicated by an impulse on wire A. The individual digits do not need to be in normal order, a signal on lead P restoring the order to normal. The several first group selectors are effective in turn to record metering pulses if they occur.
