1 CMA 5000 extended Transport Analysis Application Next Generation SONET/SDH Option Key Features Ideal tool for Next- Generation SONET/SDH measurement in a field environment LCAS source and sink state machines emulation Ethernet over SONET/SDH User friendly GUI The last decade has seen a tremendous evolution of transport technologies. SONET/SDH, which are still today the predominant transport standards present in the metropolitan and core networks have migrated from a rigid hierarchy of bit rate for voice network, to a transport medium for a wide variety of non-traditional data. This evolution was facilitated in part by recent innovations such as ''Next-Generation SONET/SDH'' technologies. ''Next-Generation SONET/SDH'' is a generic term including different technologies: Virtual Concatenation (VCAT), Link Capacity Adjustment Scheme (LCAS), Generic Framing Procedure (GFP). The objective of these technologies is to adapt the legacy SONET/SDH networks to transport data more efficiently. For the operators and carriers, the advantages of the evolution of SONET/SDH are obvious: efficiency, flexibility, new service revenues and more. However, for the engineers and technicians who have to install, turn-up and maintain today's networks, specific test instruments capable of handling these different technologies are needed. The CMA 5000-XTA module with its Next-Generation SONET/SDH option is the perfect tool for field technicians. All operations will be tremendously simplified by the easy-to-use graphical user interface that is characteristic of all CMA 5000 applications. The Next Generation SONET/SDH option will make configuring and performing tests on the XTA application virtually automatic. Specifications
