Framed or Unframed E1 Optical Ethernet Converter

This interface converter is based on FPGA, providing one framed E1 interface and one Ethernet interface to achieve 10/100Base-FX  Ethernet data transmission on the E1 channel. It is a high performance, self-learning Ethernet bridge. This device is the extension device of Ethernet, using network (PDH/SDH/Microwave) that provide E1 channel to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance.

◆ Based on self -copyright  IC
◆ Can realize monitor and control of remote equipment, OAM management data did not  take up user’s  timeslot and save E1 bandwidth
◆ E1 supports any timeslot set, the rate is 64K-2048K
◆ 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;
◆ Have indicator light 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 (2036 Bytes);
◆ Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering
◆ Ethernet interface supports 100M, full duplex , support VLAN
◆ Have Ethernet monitor self-reset function, the equipment will not dead
◆ The local device can forced the remote device rate follow it ( valid when framed)
◆ 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;
◆ Support SNMP Network Management;
◆ Can realize monitor of remote equipment temperature and voltage from local equipment;
◆ Can form the structure: Ethernet E1 Bridge(A)－－-Optical Ethernet Modem(B)－－-Ethernet Optical Fiber  Transceiver (C), can manage (B) and (C) at (A)
