ABSTRACT:
A channel switching system includes a synchronizing switch circuit including: two converters for monitoring input data signals respectively supplied through a regular channel and a stand-by channel, and when continuation of a predetermined number of bits having the same value is detected, outputting data signals for comparison in accordance with a predetermined rule; and a bit comparator for reading out the comparison data signals in response to a common clock signal, comparing bits of the data signals, sequentially changing the order of signal lines of either of the regular channel and the stand-by channel when a bit noncoincidence is detected, and supplying a control signal which instructs channel switching when a bit coincidence is detected.
