摘要： The present invention is a SONET system for use in large geographic areas, such as areas encompassed by an IXC network, or which are larger than a LATA or a metropolitan area. The system uses self-healing rings which are interconnected. Some of the rings are stacked within the same physical routes in order to minimize the number of ring terminals on each ring.
