E1 To Ethernet Converter

E3/DS3/STS-1 To 4FE Converter

Overview
The interface converter) using large scale FPGA design E3/DS3/STS-1 interfaces and four 4x10/100base-T Ethernet interface converter 10/100base-T channels will be transferred to the switch HUB routers bridges or other device.  This device is a high performance adaptive remote Ethernet bridge. Its small size low cost very suitable for cost-sensitive bridging applications or as a LAN extender or slicer bitstream on infrastructure. Can automatically learn continuously connected LAN MAC address on the destination address of the frame and another LAN forwarding. On the TCP/IP protocol transparent provide security for the communication network between the different interface devices seamless connectivity. This equipment is widely used between WAN and LAN networking monitoring field.
Features
◆ based on self -copyright IC ;
◆ Integrated Transmitter Receiver and Jitter Attenuator for DS3 E3 and STS-1;
◆ Have the function of E3/DS3/STS-1 interface loop back check avoid the converter crashed because of interface loop  return;
◆ E3 Interface Ethernet Bandwidth is 34.368Mbit/sDS3 Interface Ethernet Bandwidth is 44.736Mbit/sDS3 Interface Ethernet Bandwidth is 51.84Mbit/s;
◆ 4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently;
◆ Ethernet interface supports10M/100M half/full duplex auto-Negotiation and AUTO-MDIX (crossed line and  straightly  connected line self-adaptable );
◆ Provide 2 clock types: E1 master clock and E1 line clock;
◆ Have two Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG); 
◆ Provide 75 Ω unbalance coaxial cableB3ZS/HDB3 decoding and loss-of-signal monitoring;
◆ AC 220V DC-48V DC+24V DC Power and DC-48V/DC24V power has polarity automatic detection function you can install the device without differentiation between positive and negative polarity.
