4x E1 over Ethernet with Web Management


  • Multiservice access platform for PDH over Ethernet applications
  • Provides cost-effective applications of traditional circuit switched system over Ethernet
  • Interconnects existing phone systems over Ethernet that are used to carry data, voice and video
  • Supports IEFT RFC4533 Structure-Agnostic TDM over Packet (SAToP), Metro Ethernet Forum MEF8.
  • 4 x E1 NRZ Serial Interface with LOS/AIS detection
  • Use Raw Encapsulation method for PDH payload over IP packet.
  • Supports Circuit Emulation Service over IP.
  • Comply with IEFT draft standard for CESoPSN and SAToP; Metro Ethernet Forum MEF8 IA.
  • Supports Point-to-Point operation.
  • Supports 4 independent Adaptive Clock recovery block for Ingress PDH (PSN -> TDM) clock generation. Recovered clock jitter is compliant with ITU-T G.824 (E1 Jitter Control)
  • Independent configurable jitter buffer depth to compensate up to 250ms of Packet Delay Variation
  • Supports framed/unframed traffic (ITU-T G.704)
  • Lost packets processing/compensation via PW (Pseudo Wire) control field Sequence Number.
  • Provides Subscriber side data traffic bandwidth control to guarantee enough TDM payload bandwidth.
  • PDH LOS detection triggered PWL field or payload AIS generation at Egress direction (TDM -> PSN).
  • Configurable IEEE 802.3 DA/SA assignment.
  • Configuration can be made through RS-232 console port.
