Sonet Glossary In SONET there are three different types of GNEs: A GNE that interworks an X 25 DCN (Data Comm Network) and the SONET DCC A GNE that interworks an X 25 DCN and an intra-site LAN
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
UNDERSTANDING SONET UPSRs 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
Educational Information - SONET Sonet Sync: A guide to sonet ring synchronization with practical examples of how sync messaging and sync auto reconfig are used
UNDERSTANDING SONET BLSRs There are two major types of SONET rings: path-switched and line-switched SONET rings Line-switched rings use the SONET line level indications to initiate protection switching Line layer indications include line layer failures and APS signaling messages that are received from other nodes
DEPLOYING AND TROUBLE SHOOTING A 6 NODE SONET RING 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
SYNCHRONIZATION IN SONET NETWORKS The SONET HOMEPAGE In support of evolution toward SONET-based timing distribution, SONET NEs can derive an optional DS1 timing output from the incoming OC-12, OC-48, and OC-192 optical line interfaces With this capability, the SONET NEs network can distribute high quality synchronization among its sites
