is a telecommunications technology developed by Canadian start-up Genesis Technical Systems, based in Calgary, Canada.
The DSL technology reuses existing copper telephone network cabling for a stated bandwidth of up to 50 Mb/s.
Genesis reported that two unnamed European telecom providers began testing the technology in July 2010.
The links between the houses are implemented via passive jumper wires that do not come back to the Convergence Node (CN).
The technology enables a fail-safe in that, if a single pair is cut, the traffic goes in the opposite direction around the ring to get to the network gateway node.
