1-Port T1/E1 Ethernet Network Extender Kit
2. Overview
2.1 Introduction
The LR0301A 1-Port T1/ E1 Network Extender (LR0301A-KIT) is an Ethernet extender that converts protocols and data from
Fractional T1/E1 to Ethernet 10BASE-T/100BASE-TX interfaces. It’s a symmetrical broadband solution for Intranet LAN-to-LAN
connection with Nx64kbps bandwidth. The pair of extenders included with this kit acts as a bridge, enabling you to link two
Ethernet networks across T1/E1. It supports T1/E1 framed and unframed modes with different line codes plus line build-out (LBO)
capability.
Because you are using leased lines provided by your telco, there are no distance limitations—you can extend your network any-
where you can get a T1 line. It’s ideal for various Ethernet LAN services (for example, videoconferencing, routing, etc.) through a
fractional T1/E1 network.
2.2 Features
• Supports Fractional T1/E1 framed and unframed modes
• BNC connectors for E1 unbalanced 75 ohm

• Autosensing, autonegotiating for 10BASE-T/100BASE-TX and half-/full-duplex
• Ethernet Auto MDI/MDI-X function for auto Tx/Rx swap so you don’t need a crossover cable
• 6 LED indicators for status monitoring
• DIP switches make configuration easy
• Plug-and-play
