Detailed Product Description

Product Description:

   4E1/FE converter adopts telecom line(E1 or E1 transmitting network,such as PDH, SDH, microwave, etc) to extend Ethernet. 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

  Support auto-negotiation of ethernet,10M/100M, full duplex/half duplex operation mode

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

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

  Support self-protection and automatic troubleshooting of E1 circuit
