Abstract

650,764. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Nov. 8, 1946, No. 33271. Convention date, Nov. 14, 1945. Drawings to Specification. [Class 40 (iv)] In an exchange system in which communication channels take the form of pulses at different instants in a distributer cycle the wanted subscriber's designation signals are impressed on the pulse series and means for detecting these signals is connected to the channel substantially only for the period of transmission of the designation signals, thereby to avoid possible false operation due to transients. The description is identical with part of that of Specification 644,571, which claims other features.
