Unframed E1 Optice Ethernet Converter

View : 309
Type : E1 to Fiber Etherne
Description :

This interface converter is based on FPGA, providing one unframed E1 interface and one Ethernet interface to achieve 10/100Base-FX  Ethernet data transmission on the E1 channel.

Overview

    This interface converter is based on FPGA, providing one unframed 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.

Features

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
