Overview

RB004 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.

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
