Title: Data communication system
IPC: G06F13/00
Filed: 1976-11-11
Abstract: 1531090 Loop systems INTERNATIONAL BUSINESS MACHINES CORP 11 Nov 1976 [19 Dec 1975] 47056/76 Heading H4F In a system for communicating between a central, host processor, station, and one or more remote stations (terminal devices), a remote station operates normally on a selected one of the loops, the primary loop for the station, but has access to, but does not normally use the other, its secondary, loop. For enhanced reliability each remote station has means in use associated with its secondary loop to detect a particular switching command format, which, when detected on the station's secondary loop, indicates failure on its primary loop, and causes it to switch from its primary, to its secondary loop for further communication. In a synchronous data link control system (SLDC), the switching command comprises thirty-two consecutive one bits in four 8-bit bytes, sandwiched by a pair of flag bits, see E, Fig. 2 (not shown). Data is communicated in frames comprising address, control, data, and check bytes in that order, sandwiched by flag bits. For transmission, a zero is inserted after each five consecutive ones, such zeroes being removed at reception, see F (Fig. 2). Means for detecting the switch command are disclosed in detail in relation to Figs. 3,4 (not shown). Loop failure is detected by the central station, by transmitting a test signal on a given loop, and monitoring its return or otherwise, the switch command being transmitted on the sound loop in the latter case. Subsequent to such transmission, all remote stations have the sound loop as their primary loop, until, upon correction of the fault, selected remote stations are instructed by the central station to interchange primary and secondary loops.

Sn each of which is connected to one side of a respective load B1 ... Bn, e.g. coils for moving printing mallets in a line printer, the other side of each load being connected to a supply source V1 through a common controlled rectifier CR, which after having been rendered conducting by a starting pulse C1 can only be rendered non-conducting by an extinguishing pulse C2 when the current through the rectifier CR has fallen to a low value due to all switching devices being open or non-conducting, is provided with a detector circuit which detects when an extinguishing pulse fails to render the rectifier non-conducting because the current through the rectifier is above the low value due to one or more of the switching devices remaining closed or conducting. When all the switching devices S1 ... Sn are open, a small current flows through the rectifier CR and an impedance Z. When the extinguishing pulse C2 is not able to render the rectifier CR non-conducting, the voltage produced by the small current through the impedance Z remains and a threshold device 3 is unable to provide a reset signal A to a flip-flop memory device FF. The extinguishing pulse C2 is also applied to a pulse shaper 4 which provides a time pulse B, the leading edge of which sets the device FF to provide a signal FF1 to an AND gate 5. The pulse B is also applied to an invertor input of the gate 5 so that when the extingushing pulse C1 ceases, without the flip-flop having been reset, the AND gate provides a signal, e.g. an alarm signal, or a signal effective to stop any further starting signal and to disconnect the supply V1,
