About DSL Bonding

DSL Bonding, also called inverse multiplexing or IMUX, technology combines the bandwidth of multiple DSL (Digital Subscriber Line) circuits into a single virtual data pipe.

Before DSL Bonding was developed, the maximum speed of a DSL connection was dependent on the customer's distance from the central office. DSL Bonding allows customers who are located at greater distances from the central office to aggregate DSL circuits, in order to achieve two or more times the speed otherwise available to them with a single line.

The premise behind DSL Bonding is to provide a cost-effective means of bridging the bandwidth gap between relatively low network speeds and much higher rates, thereby allowing high-speed applications to use bandwidth up to 3 Mbps.

Netopia's DSL routers and DSUs with bonding allow users with 1.5 Mbps SDSL connections to enjoy speeds of over 3 Mbps, twice as fast as T1. They also allow customers who, because of line quality problems, were previously limited to a 144 Kbps IDSL connection, to enjoy speeds of up to 576 Kbps using four IDSL lines.
