Synchronization multiplex terminal station equipment

Abstract

Abstract PURPOSE:To automatize detour switching of lines by providing plural control memories in which the content of detouring line setting is written in advance and selecting a control memory corresponding to an optimum detouring line on the occurrence of a fault in a transmission line. CONSTITUTION:A switching control section 6 gives a trigger to a selector 4 so as to select a control memory 1-3 according to a fault report from a reception interface section 7-1, the selector 4 selects the control memory 1-3 to access a data memory 5. A control memory (CM2) 1-2 having been a standby memory so far backs up the control memory 1-3 whose content is rewritten with that of a control memory (CM3) 1-3. A control memory (CM1) 1-1 is used to restore the control, in other words, a detouring memory for the control memory 1-3. Thus, no manual operation by a maintenance personnel is required and the detour switching of the line is automatized.
