E1/V.35 over Ethernet Access Unit


  • Supports IEFT RFC4533 Structure-Agnostic TDM over Packet (SAToP), Metro Ethernet Forum MEF8
  • One E1 NRZ Serial Interface with LOS/AIS detection
  • One V.35 (Nx64K) interface
  • Use Raw Encapsulation method for PDH payload over Ethernet packet.
  • Supports Circuit Emulation Service over Ethernet (CESoE) transport over Ethernet networks
  • Comply with IEFT draft standard for CESoPSN and SAToP; Metro Ethernet Forum MEF8 IA
  • Supports Adaptive Clock recovery block for Ingress PDH (PSN-> TDM) clock generation. Recovered clock jitter is compliant to ITU-T G.824 (E1 Jitter Control).
  • Configurable jitter buffer depth to compensate up to 40ms of Packet Delay Variation.
  • 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 PW L field or payload AIS generation at Egress direction (TDM -> PSN).
  • Configurable IEEE 802.3 DA/SA assignment
