Bộ chuyển đổi 2 cổng Ethernet sang E1 JHA Tech JHA-CE1FF2P

This interface converter is based on FPGA. Multiplex 10/100Base-T Ethernet 2Channel interface to E1 interface to provide users with Ethernet access at the rate of 1984K. It is widely used in finance, securities and security departments which need to be provided two different networks, and both on a physical network can be completely separated. For example, the financial system business network, internal office network and business network can’t be linked together. This interface multiplexer can solve this problem.

Tính năng

• Based on self -copyright  IC 
• E1 supports any timeslot set, the rate is 64K-2048K
• Can realize monitor and control of remote equipment, OAM management data did not  take up user’s  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 realize 2Channel Ethernet data transmission by 1 E1 circuits
• Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function
• 2Channel Ethernet rate is 1984Kbps, set up the first channel rate, the second channel Ethernet rate automatic allocation
• The local device can forced the remote device rate follow it
• Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop return;
• 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 (2036 Bytes)
• Ethernet interface supports10M/100M, half/full duplex auto-Negotiation and AUTO-MDIX  (crossed line and straightly connected line self-adaptable )
• Have Ethernet monitor self-reset function, the equipment will not dead
• 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)
• Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
• Realize monitor of remote equipment temperature and voltage from local equipment;
• Rack type Support SNMP Network Management;
