More About SONETRule

SONETRule is a software tool that enables you to design and configure circuits on networks with multiple protected rings much more accurately and quickly than would be possible without such a highly automated tool. With SONETRule you can easily incorporate circuit design policies to ensure your business needs are met.

* "SONETRule" refers to the protected ring technology for fiber optic telecommunication services. It accommodates PDH and SDH lines. "SONET" is an ANSI standard protocol used in Synchronous Optical Networks on the physical layer. "SDH" refers to Synchronous Digital Hierarchy and is basically similar to SONET. Generally ring networks involve multiple protected rings, such as MANs (Metropolitan Area Networks), connected by long-haul fiber optic lines. They typically involve ATM over SDH/SONET and typically carry multi-media services.
