Startup Genesis Technical Launches 400 Mbps Broadband over Copper Wires

– DSL Rings Technology Replaces Need for All Fiber
– Shipping Expected Q2 2013

Technology abhors a vacuum, especially if the vacuum is the
telcos’ need for higher speed broadband.

Canada-based Genesis Technical Systems has launched a
technology called DSL Rings that it says allows telcos to
offer 400 Mbps over their existing copper wires. Those speeds
will eliminate the need for telcos to deploy all fiber

Details about the technology were not provided, other than the
fact that it “is a patented, revolutionary technology” and
uses “standards-based bonded DSL technology.” The company
clearly says that DSL Rings is NOT the VDSL2 Vectoring
technology that Alcatel-Lucent is pushing.

Rather than using a pair of copper wires to each home, it uses
a convergence node that connects a number of residences in a
ring topology. There is a detailed explanation at:

and a demo of the technology at:

DSL Rings uses three existing telecom standards, RPR, VDSL2
and G.Bond. It does not require a defined technology structure
in the backhaul to the network. No new cabling is needed, it
said, because it uses the telco’s existing two copper pairs.
One pair connects to either the pedestal (or distribution
point) or to the neighboring house on the right and the other
pair connects to the neighbor on the left. This is all done
through the pedestal – the little box on the street corner.

As with DOCSIS, the broadband line is shared with neighbors
that are connected.

The company said DSL Rings is a low power solution with no
requirement for batteries or extensive power equipment. It can
be deployed without disruption to the existing network. That
eliminates the need for trenching or string wires, which is
required when deploying a new fiber network, a costly and
disruptive effort.

The company says it has completed lab trials with two
communications providers, has signed NDA’s with two others and
has expressions of interest from ten others — none of whom are

Stephen Cooke, Genesis president & CTO and previously at
Nortel said, “DSL Rings facilitates telco customer
acquisition, win-back and retention by offering better, faster
services; more bandwidth and lower unit cost (per Mbps) than
current methods of delivering broadband services over copper.”

Genesis said DSL Rings is generally backhaul agnostic and
works with both conventional copper and fiber-to-the-cabinet
(also known as fiber-to-the-neighborhood).

The company estimates that the world’s telcos have over a
trillion dollars’ worth of copper infrastructure that connects
1.2 billion homes and residences. DSL Rings means that the
copper infrastructure still has substantial physical and
usable life remaining — perhaps even for another century or

Genesis is currently scheduling DSL Rings field trials and
anticipates that the technology will be commercially available
in the second quarter of 2013.

The market for faster broadband from the telcos is large.
Genesis estimates that, in Europe alone, there are over 40
million people who currently do not have access to a basic 2
Mbps service.

Genesis Technical Systems is a privately held company with
multiple patents for DSL Rings.

DSL Rings Compared to VDSL2 Vectoring
One problem with VDSL2 Vectoring is that local loop unbundlers
(LLUs), whose broadband activities over incumbent telcos’
existing networks, can cause interference because their
network equipment and modems have not been upgraded to

The UK, for example, has LLUs such as TalkTalk, Vodafone,
Cable and Wireless and even the satco BSkyB and the cableco
Virgin Media, where they don’t have their own network. They
use the incumbent telco BT’s infrastructure — for a government
regulated fee, of course, — from BT’s central office or
distribution point to the residence. Belgacom, the incumbent
telco in Belgium, has asked for and received approval from
Belgium government regulators to exclude LLUs from using its
network in areas where it deploys VDSL2 Vectoring. Its
argument is that by blocking LLUs from using its networks, it
can use VDSL2 Vectoring more affordably and less disruptively
to provide speeds of up to 100 Mbps. That makes the regulators
and politicians happy — as well as consumers — and enables
Belgacom to more effectively compete against the cablecos and
their DOCSIS broadband technology without going to all-fiber

Incumbent telcos typically have greater coverage than the
cablecos because they supply phone service to every residence
and business.

Asked how DSL Rings stacks up against VDSL2 Vectoring, Stephen
Cooke, founder, president and CTO of Genesis, told The Online
Reporter, “Vectoring does a bunch of heavy math to pre-
condition a launched xDSL signal so that the signal can cope
with crosstalk and be better understood by the receiving
modem. The end result is that gains of 5% to possibly 100% in
practice can be achieved without any change to the current
network cabling architecture. It is a good technology and Dr
John Cioffi [founder of ASSIA], who holds most of the
vectoring patents, sits with me on the UK’s NICC standards
body. The low end of the vectoring benefits occurs when even a
single ‘alien,’ possibly from a completely legal LLU, exists
in the cable binder group with the rest of the vectored
signals. Generally the industry ‘rule of thumb’ is that
Vectoring and LLU are mutually exclusive — though John
Cioffi’s company (ASSIA) and several academics feel that a
higher-level vectoring control entity could still be used to,
at least partially, re-gain those bandwidth increases. To me
this seems like a lot of effort and industry cooperation,
which is never easy, for a maximum gain of 2x the available

“DSL Rings provides generally 20x the currently available
speeds due to our bonding of the binder and VDSL2 distribution
around the ring to a maximum of 400 Mbps (2x the current
maximum VDSL2 upstream & downstream bandwidth/pair). One thing
to note is that DSL Rings can actually use vectoring to
increase our bandwidth and transmission distance even further.
The bottom line is that vectoring can provide decent gains
under certain conditions, DSL Rings can provide substantially
higher gains under almost all conditions.”

Alcatel-Lucent, a major backer of VDSL2 Vectoring and a long-
time supplier to the telcos, this week announced a technology
called Zero Touch that will enable VDSL2 vectoring speeds to
be offered even on networks where all the DSL modems have not
been upgraded.

There appear to be some questions about DSL Rings.
– Will it require major changes in infrastructure?
– Is the technology proprietary to Genesis?
– Will not being an ITU standard be a drawback to the
standards-loving telcos and their suppliers?
– Does it work effectively only when there’s a small distance
between homes?
– Will sharing the bandwidth among homes cause speeds to drop

In short, is DSL Rings a viable alternative to G.Fast, which
is an ITU standard that many telcos, their suppliers and
chipmakers have backed? Only the telcos can answer that.

Compared to G.Fast
Asked about G.Fast, Cooke said G.Fast is a physical layer
protocol/electrical specification. Genesis’ IP is the Ring,
which is the next highest layer in the protocol
stack/architecture. In 18 months-to-2 years when G.Fast
chipsets are available, Genesis can upgrade home gateways that
have its chips G.Fast physical layer technology to further
increase bandwidth on the ring.

He said, “Please note that simply increasing the bandwidth
around the ring doesn’t do any good if the backhaul bandwidth
does not also increase in proportion — which G.Fast does not
address, other than requiring optical fiber backhaul from the
pedestal/distribution point.”
