G.SHDSL Two-Wire Ethernet Network Extender

2. Overview

2.1 Introduction

The LR0201A-KIT, a G.SHDSL (Single-pair High-bit-rate Digital Subscriber Line) Two-Wire Ethernet Network Extender, provides broadband full-duplex transmission with bandwidth up to 5.696 Mbps over a pair of copper twisted-pair lines for point-to-point LAN connectivity between two Ethernet networks. The LR0201A-KIT is a cost-effective symmetrical broadband solution for band- width-hungry applications such as LAN-to-LAN connectivity, Internet access, and VoIP applications over two twisted pairs.

Use the extenders for VoIP, Web hosting, or teleconferencing for more performance than you get with SDSL equipment. Distances reach up to 7000 feet (about 2.1 km) at 5.606 Mbps, 10,000 feet (about 3 km) at 4.608 Mbps, or 22,500 feet (about 67.8 km) at 192 kbps. Users can also select a fixed data rate for the copper line ranging from 64 kbps to 5.696 Mbps. Or, use the unit’s rate-adaptive feature, which will choose the best data rate for your link from 192 kbps to 4.608 Mbps. The LR0201A-KIT also pro- vides a console port for users to configure the settings and to monitor the connection status.

The LR0201A-KIT can be configured as either the central office (master) side or the remote (slave) side. LR0201A-KIT conforms to the ITU-T Rec. G.991.2, to meet G.shdsl.bis network requirements.

Black Box LR0201A-KIT, BLACK BOX G.SHDSL Two-Wire Ethernet Network Extender manual Overview Introduction, Features

BLACK BOX G.SHDSL Two-Wire Ethernet Network Extender, LR0201A-KIT specifications

The Black Box LR0201A-KIT is a robust G.SHDSL two-wire Ethernet network extender designed to enhance communication over extended distances while maintaining high data integrity and transfer speeds. This device is particularly beneficial in scenarios where traditional Ethernet connections fall short, such as in large facilities, campuses, or in areas where coaxial cabling is impractical or impossible to implement.

One of the main features of the LR0201A-KIT is its adherence to the G.SHDSL standard, which allows for symmetric data rates up to 5.7 Mbps over a single pair of copper wires. This makes it an ideal solution for both upload and download tasks, ensuring that businesses can maintain consistent, high-speed internet connectivity for applications such as video conferencing, VoIP, and large file transfers.

The extender is designed for ease of use, with a plug-and-play installation process that minimizes deployment time and reduces the need for specialized technical knowledge. Additionally, it supports a range of operating distances, providing connectivity over 10 kilometers (6.2 miles) depending on the quality of the existing wiring infrastructure. This flexibility allows for versatile deployment in widely varying environments.

Equipped with dual Ethernet ports, the LR0201A-KIT can serve multiple devices simultaneously, effectively distributing network access across different systems. The device also features built-in diagnostics and LED indicators for power, connection status, and data transmission, allowing for quick troubleshooting and monitoring of network performance.

Security is another pivotal aspect of the Black Box LR0201A-KIT, with support for advanced features such as VLAN tagging, ensuring that sensitive data remains protected during transmission. The ability to configure quality of service (QoS) parameters further enhances network performance by prioritizing critical data traffic.

In terms of construction, the unit is housed in a durable chassis designed to withstand various environmental conditions, making it suitable for deployment in both indoor and outdoor settings. Its compact size allows for easy integration into existing setups, ensuring that users canmaximize their space without compromising on performance.

In summary, the Black Box LR0201A-KIT is a reliable solution for organizations seeking to extend their Ethernet networks over long distances. With its combination of high-speed data transfer, user-friendly installation, dual-port capability, and robust security features, it stands out as a valuable tool for maintaining effective and efficient communications in diverse operational contexts.
