DSL Bonding, also called inverse multiplexing or IMUX, technology
combines the
bandwidth of multiple DSL
(Digital Subscriber Line) circuits into a single vir tual 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
other wise available to them with a single line.
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
other wise 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.
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.
