framed E1 Optical Ethernet Converter

Type:FCCM-E1f Message

Description:1channel framed E1 - FE converter,With E1 loopback detection function

Product Description
              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.
Functional Properties
Ø based on self -copyright  IC 
Ø can realize monitor and control of remote equipment OAM management data did not  take up user’s  timeslot and save E1 bandwidth
Ø   E1 supports any timeslot set the rate is 64K-2048K
Ø The local device can forced the remote device rate follow it
Ø Have the function of E1 interface loop back check avoid the converter crashed because of interface loop  return;
Ø Have indicator light when the device is power-off or E1 line is broken or lose signal;
Ø Can set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken;
Ø The Ethernet interface supports jumbo frames (2036 Bytes);
Ø Inter-set dynamic Ethernet MAC address (4096) with local data frame filtering 
Ø Ethernet interface supports 100M full duplex support VLAN
Ø Have Ethernet monitor self-reset function the equipment will not dead
Ø The local device can forced the remote device rate follow it ( valid when framed)
Ø Provide 2 clock types: E1 master clock and E1 line clock;

Ø Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command  

      the remote Ethernet interface Loop Back(REM)

Ø   Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
Ø   Support SNMP Network Management;
Ø   Can realize monitor of remote equipment temperature and voltage from local equipment; 

Ø   Can form the structure: Ethernet E1 Bridge(A)---Optical Ethernet Modem(B)---Ethernet Optical Fiber   

      Transceiver (C) can manage (B) and (C) at (A
