- 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 exchanges the synchronous digital signals and the Ethernet signals, and performs synchronous timeslot switching and packet switching 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 Maintenance (OAM) architecture and the scheme of multi-layered protection switching for synchronous digital signals and Ethernet signals.
