Bonded DSL Rings (BDR) is a patent pending technology that lets rural and urban telcos move voice, video & data traffic over their existing copper telephone lines at speeds of up to 400 Mbit/s. Installation costs for BDR are less than 1/20th of optical fiber. With BDR telcos can surpass cable in bandwidth and quality of service thus providing telcos with a new profitable revenue source from their existing copper telephone lines. A proof of concept of BDR was displayed at the Broadband World Forum in Berlin, Germany in October 2007 and at the MINT Lab in Edmonton, Canada in November 2007 by Genesis Technical Systems Corp. BDR combines existing technologies over telco’s existing copper telephone lines to create an entirely new revenue generation platform for telcos and delivers bandwidth that exceeds cable-based competition.

Overview

BDR works by combining existing telecom standards, in ways not previously done over existing copper telephone lines. BDR combines the capabilities of VDSL2, DSL Bonding (using G.Bond), Resilient Packet Rings (RPR) technologies and add-drop multiplexers (ADM) in a collector ring instead of the historic tree and branch approach. Until BDR the tree and branch architecture of copper telephone line’s was unchanged for over 100 years and as a result recent efforts to increase bandwidth significantly using existing copper telephone lines has not kept up with the increased bandwidth needs of today’s Telco broadband customers.

Benefits

BDR technology has resolved the distance sensitivity and cross talk problems associated with VDSL2 technology. Recently VDSL2 has given telcos increased bandwidth-carrying capability over their existing copper telephone wires but VDSL2 has not been effective over longer distances and sometimes VDSL2 results in poor IPTV reception due to cross talk. Installation of BDR resolves those issues and BDR can be installed at a cost of 1/20th of fiber. Expensive fiber and wireless based solutions involve telcos abandoning the use of their existing copper telephone lines in which they have already invested billions of dollars. BDR reuses the existing copper telephone lines. By re-cycling those lines BDR can save larger telcos billions of dollars and help to make telcos more profitable. BDR also helps make telcos more environmentally friendly by removing their need to dig up whole neighborhoods to install fiber.
