Black Box LR0020A-KIT-R2 SDSL Network Extender 2000 Kit

BLACK BOX SDSL network extenders provide affordable, high-speed LAN connections and Internet access over any grade of UTP cable - CAT5, CAT3, even CAT2.
They're ideal for use in situations where the local network and the gateway to the ISP aren't close enough to be directly attached to each other, such as in campus applications. They enable you to establish both DSL and Ethernet links on each side of your single copper pair and essentially provide a very long Ethernet connection.
