Abstract: 1434187 Automatic exchange system GENERAL ELECTRIC CO Ltd 11 May 1973 [12 May 1972] 22292/72 Heading H4K [Also in Division G4] In a multiprocessor system controlling inter alia line circuits 19 (Fig. 1), if a fault is discovered which is likely to erase information in core stores relating to, for example, the states of the line circuits 1, roll back action is taken. The roll back routine interrogates, by a processor applying the appropriate channel and subchannel address on lines 14, three interrogate wires Y, S, WS representing the states of particular relays in each line circuit and their information is transmitted back to the processor. If Y = 0 the line is assumed to be idle. If Y = 1 signifying a call is in progress the value of the signal from the wire in S is examined If S = 0 the line is assumed to have an incoming call. If S = 1 the value of the signal from NS wire is examined and if NS is 0 the line circuit is assumed to be in its incoming speech state. If NS = 1 it is not possible to determine exactly the state of the call from the signals on the three interrogate wires and the call is lost. The information derived from each line circuit is entered in the storage location assigned to it in core storage and the process then continues.
