ABSTRACT:
A communication network using a ring structure incorporates shared protection channels (22ab, 22bc, 22bd) to reduce costs in implementing protection spans. The shared protection network elements (12a, 12b, 12c, 12d) use a protocol of conventional messaging to integrate with traditional fully redundant network elements.
