  • Method of failure protection for digital transmission system in ring configuration, and relevant multiplexing device
    Publication number: 20060008271
    Abstract: A method of failure protection in a digital transmission system having a plurality of transmission elements connected in a ring configuration over metallic media, said ring configuration being formed by at least two paths, one path as a normal path for the transmission at the normal status, another path as a backup path which forms a closed loop and has no connection with said normal path at the normal status, said normal path and said backup path having opposite transmission directions, said method comprising the step of connecting said normal path and said backup path in said transmission element through hardware when a failure happens in said normal path so as to maintain the transmission. A digital transmission system with less expensive transmission elements and better failure protection can be obtained accordingly.
