1. A SONET system which comprises:
- (a) a plurality of SONET ring terminals;
(b) a plurality of SONET spans connecting the ring terminals to form an architecture comprising a plurality of rings wherein each ring is comprised of unique ring terminals and spans and is not comprised of any ring terminals and spans of another ring, and wherein particular spans of different rings are stacked within a single fiber route; and
(c) a plurality of connections between the rings that are operational to provide interconnectivity among the rings.

Abstract
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.
