    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.
