Abstract: 1,206,082. Exchange systems; data transmission. SIEMENS A.G. 25 Feb., 1969 [26 Feb., 1968], No. 10007/69. Addition to 1,205,309. Headings H4K and H4P. In a system to transmit a message comprising an arbitrary number of equal sized words, the number of such words comprising the message being sent as a prefix to the message, a first counter is set to a position indicating the number of words in the message, a second counter being stepped forward while the first counter is stepped back from its set position for each word of the message as it is dealt with, the count achieved by the second counter being compared with the original message length indication when the first counter steps back on zero. A fault indication is generated if the second counter does not match the message length indication. Fault indications are also generated if either counter is faulty or if the first counter is given insufficient stepping pulses to regain its zero position. The invention is employed in an exchange system of the kind described in Specification 1,205,305.
