In current SDH transmission equipment, channel switching for channel cutoffs and hardware failures, etc., is automated. However, instantaneous signal loss can occur with such channel switching. Protecting a system from failures with a high reliability for network failures is an important task. n n n nIn this paper, a new hitless frame-switching scheme that triggers switching by detecting bit errors for each frame is proposed. This scheme does not allow a loss of even one bit in downstream equipment even when a sudden failure occurs. In addition, it improves the error rate of the downstream equipment under normal operating conditions by switching to an error-free frame for each frame. It has been confirmed in a trial LSI with a path (virtual container-4: VC-4) as a frame that these capabilities are realized with precision.
