Hot swap extender without powering down.
A switch configures the extender for local (CO) or remote (CP) use.

This 10BASE-T/100BASE-TX Hardened Ethernet Extender uses vDSL to provide an easy, inexpensive way to extend the reach of your Ethernet network over ordinary voice-grade copper wire. Use the Hardened Extender for harsh environments and extended temperature ranges. Because you use your existing copper infrastructure, you save on cabling costs. Plus it has an internal switch and four Ethernet ports, so you can use it to easily add remote ports at the edge of your network.

<b>Easy setup</b>
Just plug a hardened extender into each end of your copper wire and use simple DIP switches to set one unit as local (CO) and the other as remote (CP).

The extender is transparent to upper level protocols such as TCP/IP, and there's never any software to install. Plus, the RJ-45 port autosenses speed and duplex, and it features MDI/MDI-X, so your Ethernet is virtually foolproof!

Desktop or wallmount
You can use this compact extender as a desktop or a wallmount standalone unit.

NOTE: Must be used in pairs with another LB304A, with the 1-port version of this extender (LB303A), or with the LinkGain Ethernet Extender over VDSL (LB300A-R3).
