E1 to Ethernet Protocol Converter
E1 to Ethernet 10/100Base-T Protocol Converter adopts the ASIC chip which features simple circuits and compact structure and enhances the reliability of the integrated equipment. It provides data transmission channels at a maximum bandwidth of 2.048M for the Ethernet over coaxial cables and connects two LANs through coaxial cables. Thus two LANs can be connected to be two internet segments and use the same IP address via transmitting equipment such as multiplexer. The E1 Ethernet protocol converter is applicable to multiple application scenarios including LAN extension, network isolation, and access of LAN into WAN. As the expander and sector based on bit flow constructer, it has two work statuses: flirting and no-flirting, traffic can be transferred on WAN or not these two statuses are decided by these two statuses. The maximal speed of filtrating and transfer can be 30,000frame/s, buffer can hold 256 frames, taking in and sending out volume is 1 frame.
