Detailed Product Description

    4E1/Ethernet protocol converter realize Ethernet transmission over 1~4E1. It converts Ethernet frame structure to E1 frame structure, and recovers E1 frame structure to Ethernet frame structure at the other side, which enables Ethernet data to transmit in telecom network based on E1. Because it is effectively used the spare bandwidth of telecom providers, saves the networking cost and improves the efficiency and can be used immediately.

Technology Characteristics:
  Transparent transmission of Ethernet data in 1-4 E1 circuits, as using 4 E1,mostly bit is 7.68Mbps

   Automatic Protection and Retorer of E1 circuits

   Have auto-negotiation function of Ethernet,10M/100M and full  duplex/half duplex operation mode

   Enable transparent transmission of ultralong frame specified by IEEE 802.1Q, support Ethernet switches with VLAN function

   Built-in address list (1024) for dynamic Ethernet MAC, supply the filtration function for local dada frame
