Abstract
1,102,257. Digital data communication system. WESTERN ELECTRIC CO. Inc. 28 July, 1965 [23 July, 1964; 28 July, 1964], No. 32159/65. Heading G4A. [Also in Division H4] A modification of the communications unit of Specification 1,102,258 incorporates a filter device acting to pass information proceeding to preselected receiving stations but to prevent data from reaching the other receiving stations. The filter comprises a set of gates acting as modulo 2 adders which receive appropriate bits of the six-bit multiplexed word according to the matrix PI*P
