UNDERSTANDING SONET UPSRs A major advantage of SONET networks is their standardized APS (automatic protection switching) schemes SONET systems can be configured as point to point terminals, linear add-drop chains and rings
SONET GLOSSARY The glossary is meant to be more than just a list of acronyms but I try to give enough explanation of each term so that it adds to the readers understanding of SONET in general
The SONET Home Page SONET networking special interest group home We have SONET tutorials, metro ethernet tutorials, DWDM, optical networking,turning up and troubleshooting sonet rings a vendor list, as well as other things of interest to those involved in engineering SONET systems
DEPLOYING AND TROUBLE SHOOTING A 6 NODE SONET RING SONET rings provide a fault tolerant, and flexible transmission architecture Deploying SONET in a private network campus application provides the user with a great deal of flexibility
Microsoft Word - sonet sync for sonethome. doc With this capability, the SONET NEs network can distribute high quality synchronization among its sites For example, the building integrated timing supply (BITS) clock in each office can be synchronized using SONET facilities by using the DS1 timing output from SONET NEs in each office
