High definition Rs485 Converter - Unframed E1-4FE interface Converter JHA-CE1F4 – JHA

Unframed E1-4FE interface Converter JHA-CE1F4

Overview

This protocol converter (interface converter) using large scale FPGA design, ITU-T G.703 standard unframed E1 interfaces and four 10 / 100Base-T Ethernet interface converter, 10 / 100Base-T channels will be transferred to the switch, HUB, routers, bridges, or other device. And through Optical and other transport equipment were transferred, networking can be composed of different network segments. 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 
• Can realize monitor and control of remote equipment, OAM management data did not take up users’  timeslot and save E1 bandwidth
• Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop  return;
• Have indicator  when the device is power-off or E1 line is broken or lose signal;
• Can set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken; The Ethernet interface supports jumbo frames (1916 Bytes);
• 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 three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM) 
• Have pseudo random code test function, easy the installation and maintenance;
• Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
   Have Ethernet monitor self-reset function, the equipment will not dead
• Ethernet interface supports the counters of receiving and transmitting frame, receives wrong frame counters.  E1 interface supports the counters of receiving wrong frame;
• Support SNMP Network Management;
• Realize monitor of remote equipment temperature and voltage from local equipment; 
• Can form the structure: Ethernet E1 Bridge(A)－－-E1 Optical Fiber Modem(B)－－-Ethernet Optical Fiber Modem (C)
