Abstract

473,015. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. April 3, 1936, No. 12047 /37. Divided out of 473,003. Drawings to Specification. [Class 40 (iv)] In a satellite exchange, a mechanical impulse repeater or " regenerator," as described, for example, in Specification 458,095, forms part of common apparatus associated with a selector when a call is made. For main-exchange calls, the selector is automatically set to the first level to select an outgoing junction after which the whole dialled number stored by the regenerator is retransmitted to the main exchange. For local calls, the selector is set by the first of the retransmitted digits and any unnecessary digits may be absorbed. The common apparatus also controls zone-metering. The invention is described with reference to a system identical with that described in Specification 473,003. Specifications 391,151 and 469,184 also are referred to and the Provisional Specification refers to Specification 435,411.
