E1 to Ethernet Protocol Converter

1.Name:E1 to Ethernet Protocol Converter 2. Product Description 4E1/ 4* Ethernet Protocol Converter is a special Ethernet bridge designed for using multiple E1 circuits to transmit Ethernet data, able to transmit MAC frame data in a point-to-point manner through 1-4 E1 circuits. The designed maximum transmission speed is 7.68Mbps with the full 4 E1. 4E1/ 4*Ethernet adopts reverse multiplexing technology, bundles multi E1 circuits to transmit 10M/100M Ethernet data, and allows a certain transmission time delay as in different linkers among E1 circuits. It can use the resource of many existing E1 circuits in telecommunication network to extend the Ethernet transmission distance and the scope of application with little investment, an excellent solution for broadband access of Ethernet Technology Characteristics > Transparent transmission of Ethernet data in 1-4 E1 circuits > Comply with IEEE 802.3 protocol standards, support auto-negotiation for 10M/100M, full duplex/half duplex operation mode > Enable transparent transmission of ultralong frame specified by IEEE 802.1Q, support Ethernet exchange with VLAN function > Built-in address list (1024) for dynamic Ethernet MAC, supply the filtration function for local dada frame > Built-in verification module for Ethernet data frame FCS, with output of verification alarm > E1 interface compliance with ITU-T G.703, G.704 > Support HDB3 code pattern > Support usability check and self-protection and automatic troubleshooting of 1-4 E1 circuits > Complete output of circuit alarm message Interface Parameters E1 Interface: > Unbalanced interface 75Ω, BNC coaxial connector Ethernet Interface: > IEEE802.3 Ethernet standard compatible >10M/100M through auto-negotiation >Full/Half duplex through auto-negotiation. > Connector: RJ-45 General characteristics >Raging from -36V to -72V for DC-48V > Ranging from 165V to 265V for AC 220V >Power consumption: <5W > Temperature: 00Cto 500C > Humidity: ≤95%(350C)
