Bonded DSL Rings

Bonded DSL Rings

An emerging technology from Genesis Technical Systems Corporation, Calgary, Alberta, Canada (www.genesistechsys.com) that enables telephone companies to deploy high-speed DSL service over existing copper lines. A Genesis "Convergence Node," which is powered from the central office, is installed in the pedestal (green or gray box) that services houses directly. It terminates approximately 25 copper wire pairs from the telco central office that have been bonded together (see G.bond).

Neighborhood Rings
Rather than continue the traditional tree and branch structure from the pedestal to the houses, Bonded DSL Rings create a resilient packet ring (see RPR) between neighboring houses. In each house, two telephone wire pairs are connected to a "Genesis Home Gateway," which creates the ring by using one pair for "in" and the other for "out." Bonded DSL Rings also accommodate existing telephone service in various ways, including filtering out the voice from the DSL as well as supporting full voice over Internet (VoIP) service. In addition, quality of service (QoS) is provided by tagging real-time voice and video traffic as high priority.

High Capacity and Cost Savings
Bonded DSL Rings provide up to 400 Mbps transmission that is shared among some 15-25 households that are within 4.3 miles (7 km) from the central office. It enables telcos to implement high-speed DSL service without the huge expense of laying optical fibers, especially in rural communities. Genesis Technical was founded in 2006 to pursue this technology, and customer implementations worldwide are expected in 2011.

From Trees to Rings

Bonded DSL Rings turn the traditional tree and branch architecture into rings that enable existing copper infrastructure to deliver high-speed DSL service.
