Abstract
Provided is a cross connection system for time-division multiplexed signals, upon detection of deterioration in quality, performs line setting to easily switch to a line having another directional orientation. The cross connection system receives an SDH interface signal, separates a virtual container line signal that is multiplexed into the SDH interface signal and connects the virtual container line to one of a number of output terminals, and is constituted by a signal receiver for receiving a primary signal, for detecting alarm information contained in the primary signal that is received, and for performing conversion of the primary signal in consonance with an occasion when the alarm information is detected, a signal synchronizer for, upon receipt of the primary signal and the alarm signal from the signal receiver, switching phases for the primary signal and the alarm information by using a first clock and for outputting the results, and a TSI function section for exchanging the primary signals received from the signal synchronizer for individual time slots of the primary signals.
