Abstract
1462807 Checking data communication COMPAGNIE HONEYWELL BULL 10 May 1974 [14 May 1973] 20896/74 Heading H4P A data processing unit at a main station 2 is coupled to distant terminals 3, 4, 5 via telecommunication lines 6, 7, 8 via telecommunication adaptors 19, 20, 21, the adaptors including logic units 25 controlled by the main station so that they can be taken sequentially out of service and while out of service receive checking signals from and transmit responses to a checking unit 26, 27, programmed from the processing unit on the basis of the parameters characteristic of the communications transmitted by the said adaptors. Conversion units 9 to 14 which are MODEMS for telephone lines or telegraphic type for telegraph lines are provided. The checking unit is programmable to cope with different types of communication, i.e. whether synchronous or asynchronous and of different transmission speeds and character lengths. The checking unit may give an alarm signal in the event of certain faults.
