Abstract

944,163. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. July 8, 1960 [July 9, 1959], No. 32642/62. Divided out of 944,162. Drawings to Specification. Heading H4K. The description is identical with that of Specification 944,162 but the claims are directed to the feature of providing a class-of service indicating circuit which in response to signals from the register provides the class indication for a calling line directly to the register. Specifications 734,345 and 794,812 also are referred to.
