Filed: 1972-02-07
Abstract: 1348092 Digital transmission; stations connected to a common line INTERNATIONAL BUSINESS MACHINES CORP 7 Feb 1972 [9 March 1971] 5509/72 Heading H4P In a system having a plurality of terminals operating in different codes and connected to a common path whereby data characters from one terminal may coincide with control characters of another terminal and vice versa, monitoring means are employed at each terminal to alter data characters which coincide with control characters of another terminal. In the embodiment described, transmission is in blocks in the form control, data, control, sync. and end of block characters; chance control characters are altered by insertion of one or more bits at a transmitter and removal at a receiver. Control characters are stored in respective codes i, j in registers 85, 87 in that the transmitting mode an X input is placed on line 33 enabling gates 35, 79 with data TD being applied on line 31 and clock pulses TC on line 51. An 8 stage shift register is formed by 63, 69, 71 into which a seven bit block is entered. If identity is found by logic circuits (not shown) bits 2-7 are shifted one position to the right and an additional bit is inserted into 69. Data is then shifted to line.  In the receive mode X input is actuated enabling gates 41, 59 and data is shifted into register 63, 69, 71 and contents are compared with register 95. Identity will cause a signal on path 97 to disable clock pulses on gate 55 temporarily to allow a bit in 69 to be cancelled and the bit in 63 to be shifted one stage to 69 thus restoring the character to its original form which is then passed to a receiving device.
