Supported Tools/Features The G.168 Echo Cancellation algorithm comes in three variants, each of which is designed to suit a specific type of application; Line (Short Tail), Network (Long Tail), and Packet EC (VoIP).
  • The Line EC is designed to operate inside a device that has a local hybrid circuit.
  • The Network Echo Canceller (NEC) is designed to operate in network equipment that may not have an internal echo source.
  • The Packet EC is able to handle round-trip delays of 512 msecs, and to mitigate the specific effects that packet loss has on echo cancellation in the VoIP network.
