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
• RJ-48 connector for E1 balanced 120 ohm and T1 balanced 100 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
2.3 What’s Included
Your package should include the following items. If anything is missing or damaged, contact Black Box Technical Support at
724-746-5500.
• (2) LR0301A 1-Port T1/ E1 Network Extenders
• (2) Power cords

3. Installation
The 1-Port T1/ E1 Network Extender uses DIP switches for fast and easy configuration, so it can be installed quickly. Follow the
steps listed below to complete the installation and configuration. There are two external DIP switches on the front of the unit and
four internal DIP switches on the circuit board inside the unit. You will use the external DIP switches for both full and Fractional
T1/E1. You will only use the internal DIP switches for Fractional T1/E1 configuration.
1. Select the Fractional E1/ T1 interface configurations via SW1-1–SW1-7 DIP switches. The default setup is T1. The DIP
switches are on the front panel. Refer to Figure 3-1 and Table 3-1 to see the DIP switches’ locations and definitions.
Figure 3-1. SW1-1–SW1-7 DIP switches.
NOTE: Table 3-1 describes DIP switches SW1-1–SW1-7. Tables 3-2 through 3-5 describe these switches in more detail. Table 3-5
also describes DIP switch SW2-1.

The SW4-1–4-8, SW5-1–5-8, SW6-1–6-8, SW7-1–7-8 DIP switches are on the PC board. You need to open the top of the case to
configure these DIP switches. Refer to the Figure 4-1 to see the DIP switches’ locations. DIP switch “ON” means selected, and
“OFF” means unselected.
NOTE: SW4-1–4-8, SW5-1–5-8, SW6-1–6-8, and SW7-1–7-8 DIP switches are active only in Fractional T1 or Fractional E1 mode.
