Abstract
1,119,734. Automatic exchange systems. SIEMENS A.G. 30 Jan., 1967 [31 Jan., 1966], No. 4355/67. Heading H4K. In a system in which a switching network is controlled by markers M1 . . . Mn, in the event of a fault occurring, for example, in the control line 1, a device A is taken into use to switch out the original marker, locate and eliminate the fault and then to switch in an alternative marker, the contacts 4 . . . 6 being closed in succession.
