摘要: A hitless path switching method without a bit loss. The same digital line signals on working and protection are continuously monitored independently for errors. If error occurs in the no path, trigger is produced operation from to performed data block basis. Only correct transferred downstream apparatuses. Reliable achieved not only response failure but also error. Using blocks of one frame length with an indicator checking placed at its beginning or top makes effective possible.
