CT Negative SDH

Grooming Mechanisms in SONET/SDH and Next-Generation SONET/SDH

Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) are very closely related standards, which came into being primarily as a means of transporting telephone traffic in large volumes utilizing optical fiber transmission systems. SONET was brought forth by Bellcore (Telcordia), with coordination from International Telecommunication Union (ITU) as well as other standards or...

Geoffrey Dutton's SDH 96 Paper

Planetary geocoding using polyhedral tessellations are a concise and elegant way to organize both local and global geospatial data that respects and documents locational accuracy. After a brief review of several such spatial referencing systems, topological, computational, and geometric properties of one of them are examined. The particular model described in the remainder of the paper – the oc...
