- Abstract
- As Next Generation -Synchronous Digital Hierarchy (NG-SDH) based switching system, which integrates and provides the connection of synchronous digital (SONET/SDH) signals and Ethernet signals, mutually change the synchronous digital signals and the Ethernet signals, synchronous timeslot switching and packet switching, and configuration and control functions in one system. This system needs the integrated monitoring and control functions for equipments deal with synchronous digital signals and Ethernet signals, and when it occurs faults, has to provide the protection switching functions for the survivability of networks. This paper presents the integrated multi-layered Operation, Administration and Maintenance (OAM) architecture for synchronous digital signals and Ethernet signals, and the scheme of multilayered protection switching for our developing NG-SDH based switching system (QSS120 120Gbps switching system).
