E1/4x E1 over Ethernet with Web Management


  • Cost-effective applications of traditional circuit-switched system over IP.
  • Easy to interconnect existing phone systems over IP that are used to carry data, voice and video
  • Transparently transports proprietary signaling that are required to support PBX features, including call conference, call forwarding and SS7
  • Supports Web Management
  • Supports IETF RFC4553 Structure-Agnostic TDM over Packet (SAToP), Metro Ethernet Forum MEF8
  • Use Raw Encapsulation method for PDH payload over Ethernet packet
  • Supports Circuit Emulation Service over Ethernet networks
  • Comply with IETF draft standard for CESoPSN and SAToP; Metro Ethernet Forum MEF8 IA
  • Supports both Point-to-Point and Point-to-Multipoint operation
  • Supports Adaptive Clock recovery block for Ingress PDH (PSN -> TDM) clock generation. Recovered clock jitter is compliant to ITU-T G.823 (E1 Jitter Control)
