16 Channel E1 over Ethernet (TDM over IP)


  • Multi-service access platform for PDH over IP applications
  • Provides cost-effective applications of traditional circuit-switched system over IP
  • Can transparently transport 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
  • 8 /16 x E1 NRZ Serial Interface with LOS/AIS detection
  • Use Raw Encapsulation method for PDH payload over IP packet
  • Supports Circuit Emulation Service over IPE
  • Comply with IETF draft standard for CESoPSN and SAToP; Metro Ethernet Forum MEF8 IA
  • Supports both Point-to-Point and Point-to-Multipoint operation
  • Configurable IEEE 802.3 DA/SA assignment
  • Supports 8/16 independent Adaptive Clock recovery block for Ingress PDH (PSN->TDM) clock generation. Recovered clock jitter is compliant with ITU-T G.823 (E1 Jitter Control)
  • Independent configurable jitter buffer depth to compensate up to 250ms of Packet Delay Variation
  • Lost packets processing / compensation via PW (Pseudo Wire) control field Sequence Number
  • PDH LOS detection triggered PW L field or payload AIS generation at Egress direction (TDM->PSN)
  • LED alarm display for E1 Power failure status
