The TDM over IP PacketLINK family provide single and multi-port connectivity solutions for Nx64kbps E1/T1 services across IP networks, including either simple point-to-point links or more complex WAN infrastructures.

TDM over IP - PacketLINK

TDM over IP - PacketLINK

  • 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)
  • Configurable jitter buffer depth to compensate PDV (Packet Delay Variation) with the flexible setting of 11ms, 23ms, 40ms, 75 ms
  • Lost packets processing / compensation via PW (Pseudo Wire) control field Sequence Number
  • Provide 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
  • LED alarm display for E1 Power failure status
  • E1 NRZ Serial Interface with LOS/AIS detection

The PL1100 and PL1400 TDM over IP devices are designed as a multi-service access platform for PDH over IP applications. E1 frames can be mapped/de-mapped into/ from IP packets. An adaptive clock recovery method for Ingress PDH (PSN->TDM) clock generation is implemented to support E1 (ITU-T G.823) Jitter performance.

The PL1100 and PL1400 TDM over IP devices provide cost-effective applications of traditional circuit-switched system over IP. It is easy to interconnect existing phone systems over IP that are used to carry data, voice and video. With high precision clock recovery technology, members of the PacketLINK family are capable of supporting 2G/3G/4G backhaul and provides smooth services. The PacketLINK family can transparently transport proprietary signaling that are required to support PBX features, including call conference, call forwarding and SS7. Customer can easily apply and enjoy better integration of TDM and IP devices with lower network expense. With a pair of PacketLINK TDM over IP devices and guaranteed internet bandwidth, it is sure to save cost dramatically, and to ensure the QoS of voice based on interconnections of TDM equipment.
