Black Box SDSL Network Extender Provider Unit - router

Black Box' SDSL Network Extenders provide home users and businesses with dedicated digital Internet and LAN connections over copper pairs. 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 - places like campus-based businesses, multiple-unit apartment buildings, and urban areas. They work over the phone-line cables already installed at your site (although they mustn't be attached to working phone lines). So you won't be paying for new installations or expensive T1 connections - and you don't even have to subscribe to DSL service. Because installation is simple and the only thing you have to configure is the data rate, you won't incur extra training costs. All models do symmetrical data transfer, which makes them ideal for applications in which two network segments - two clinics at a hospital, for instance - need to be able to send and receive data at equally fast rates. A broadcast-limiting feature ensures that broadcast traffic only consumes up to 20% of the total bandwidth. However, this only applies to pure broadcast traffic; unicast and multicast traffic are guaranteed at least 80% of the available bandwidth.
