Abstract: 993,345. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. Sept. 27, 1963 [Oct. 5, 1962], No. 38194/63. Drawings to Specification. Heading H4P. In a telegraph system in which signals are transmitted in blocks and in which errors are corrected by repetition, each repetition is proceded by a synchronization block. The receiver includes two counters and a plurality of gates to ensure that the correctly received blocks are passed to utilization equipment in the correct order. When a faulty block is received the first counter is set to a value dependent upon the value of the second counter and it counts each block until a synchronization block arrives, whereupon it resets to zero. The arrival of the synchronization block causes the second counter to take up a value dependent upon that of the first counter, and the count is reduced by one as each block is received until it reaches zero. The blocks of signals are passed to the utilization equipment only when both counters are at zero. The operation of the system in response to faults in the forward and/or backward channels is detailed in the Specification.
