ETH over 1E1
Ethernet over 1E1 Converter--support Point to MultiPoint Convergence
 
1. Overview

FB004 is an Ethernet to E1 converter with one copper fast Ethernet interface and one 75Ω/120Ω E1 interface*. It is featured by ultra-compact, cost-effective and low power consumption, which is ideal for application areas such as network access, transparent LAN service and LAN extension. 
*: Note that the 75Ω/120Ω impedance is optional, which should be declared before order.
 
 
2. Feature
 
Realizes 10M/100M Ethernet transmission over E1 cable.
 
Ethernet Interface
      ---> One fast Ethernet interface compliant with IEEE 802.3/802.3u, adopts RJ45 connector,
              supports auto- negotiation, which can work in 100M full/half-duplex, 10M full/half-duplex mode.
     ---> Illegal frames such as bad CRC packets, runt packets (less than 64 bytes) or oversize
              packets (more than 2031 bytes) can be discarded.
     ---> PAUSE flow control ability in full duplex mode.
     ---> Auto MDI/MDX function.

 

E1 Interface
      --->  Bit rate is 2.048Mbit/s.
     ---> One E1 interface compliant with ITU-T G.703 with optional 75Ω/120Ω impedance.

 

Encapsulation
      --->  Supports HDLC encapsulation compatible with RJ017*.
     ---> Supports GFP-F encapsulation compliant to ITU-T G.7041 standard.

 

Remote loop and Embedded BERT (Bit Error Ratio Tester) testing function
 
Necessary E1 Alarm indications such as LOS, LOF,AIS and CV
 
RJ017 is an Ethernet bridge chip produced by RAD Data Communications, Israel.
