Description

The Black Box LR0300 Series is a compact, managed solution that bridges Ethernet networks across T1/E1 circuits. Each kit includes two extenders that act as a bridge, enabling you to link two LANs over telco-provisioned leased lines with a steady 2 Mbps payload. With no practical distance limits when you’re using dedicated T1/E1 circuits, this extender kit is ideal for multi-site offices, campuses, manufacturing floors, and data-center interconnects where reliable, predictable bandwidth is critical. Built for business environments, the LR0300 Series combines simplicity with robust management features, giving network administrators visibility, control, and a pathway to scalable, secure WAN-like connectivity across sites.

  • Long-distance Ethernet bridging over T1/E1 leased lines: The LR0300 kit enables you to connect two Ethernet networks across a telco-provisioned T1/E1 link, delivering a dedicated, predictable 2 Mbps bridge. Because the link uses leased line infrastructure, you can extend your network over substantial distances—up to 1 kilometer per link in typical deployments—without sacrificing integrity or performance. This makes it an excellent choice for linking branch offices, warehouses, and remote facilities to a central network.
  • Managed, scalable solution for administrators: As a managed extender, the LR0300 series provides remote configuration, monitoring, and management capabilities. Network admins can tune performance, apply QoS, and segment traffic to preserve critical applications. With a centralized management mindset, these extenders support ongoing network optimization, easier fault isolation, and proactive maintenance—reducing downtime and improving service levels for voice, video, and data traffic.
  • Plug-and-play pair that forms a robust bridge: The kit includes two extenders designed to operate together as a single bridge. Each unit sits at opposite ends of the T1/E1 link, converting Ethernet frames for transport over the leased line and reconstituting them at the remote site. The pairing is straightforward, minimizing on-site configuration and accelerating deployment while preserving compatibility with existing Ethernet devices on both ends.
  • Traffic prioritization with QoS and straightforward network integration: Built to support business-critical applications, the LR0300 Series supports QoS policies that prioritize voice, video, and essential data traffic. VLAN tagging and related features help segment traffic, improve bandwidth efficiency, and ensure predictable performance for applications that require low latency and minimal jitter across the bridge.
  • Rugged, reliable design for everyday business use: Engineered for continuous operation in office environments and light-industrial settings, the LR0300 extenders emphasize reliability and compatibility with standard Ethernet devices. The kit is designed to integrate seamlessly with your existing network gear, providing a transparent bridge that preserves native Ethernet behavior while leveraging the benefits of dedicated T1/E1 transport.

How to Install the LR0300 Series Extender

  • Place each extender at opposite ends of the network you intend to connect, near the equipment that will operate on each LAN.
  • Connect the T1/E1 leased line between the two extenders according to your telco’s provisioning and wiring guidelines.
  • Attach your local Ethernet devices to the LAN port on each extender, ensuring proper cabling and network port configuration on each side.
  • Power on both extenders and access the built-in web-based management interface to complete the initial setup, verify link status, and configure bridging as needed.
  • Configure optional features such as VLAN tagging and QoS policies to prioritize critical applications, then test end-to-end connectivity by exchanging traffic between the two sites and validating performance.

Frequently Asked Questions

  • Q: What is the LR0300 Series Extender Kit used for?

    A: It bridges two Ethernet networks across T1/E1 leased lines, enabling remote sites to share a single LAN with a dedicated 2 Mbps link and up to 1 km distance per hop.

  • Q: How far can I extend the network with this kit?

    A: Each link supports up to about 1 kilometer on a T1/E1 leased-line connection. The total reach depends on the physical length and provisioning of the telco circuit between sites.

  • Q: Do I need specialized networking skills to install the LR0300 extenders?

    A: Basic networking knowledge is sufficient. The kit provides two extenders and a web-based management interface for configuration and monitoring, which streamlines deployment even for moderate IT teams.

  • Q: Can I manage the LR0300 devices remotely?

    A: Yes. The extenders include remote management capabilities via a web UI, and they can support network monitoring and configuration tasks from a central location or via SNMP in many environments.

  • Q: Are these extenders compatible with existing Ethernet devices?
  • A: Yes. The LR0300 series is designed to be transparent to standard Ethernet devices, preserving typical Ethernet behavior while transporting traffic over T1/E1 links.
