Deutsche Telekom Looks to Vectoring

Deutsche Telekom has submitted an application to Germany's Federal Network Agency to permit the use of vectoring for boosting the performance of its copper access network.

Deutsche Telekom plans to invest about EUR 6 billion over the next four years primarily to enhance its fixed network with vectoring. This upgrade would entail extending fiber optics up to the cable distribution boxes and then installing vectoring technology in the cabinets. This will enable 24 million households to benefit from the new technology.

Deutsche Telekom said the use of vectoring could boost VDSL downstream access rates to 100 Mbps, compared with top speeds in the 50 Mbps range today. Vectoring also supports upstream rates of around 40 Mbps.

In this regulatory filing, Deutsche Telekom is proposing to permit competitors to access lines that it has upgraded with vectoring. The carrier would offer a bitstream connection for vectoring available as a wholesale product.

Deutsche Telekom is also proposing that is competitors be allowed to deploy vectoring at the cable distribution boxes that they have already connected using fiber optics. Development of new areas by competitors is generally also conceivable. A prerequisite is that they - just like Telekom - allow other companies to use the new connections (open access). In addition, the "KVz-TAL" (subscriber line that runs to the cable distribution box) will generally be retained - this was a key demand of the trade associations of competitors.

"Only with vectoring can millions of households be provided with fast and efficient high-performance connections in the fixed network. We must take this opportunity for better networking of society in Germany, and that's why we have now seized the initiative with our application," emphasizes Niek Jan van Damme, Member of the Board of Management for Germany at Deutsche Telekom. In Belgium and Austria the regulatory authorities have already approved the use of vectoring with the support of the EU Commission.

Alcatel-Lucent's "Zero Touch Vectoring" Boosts VDSL2 Business Model

Alcatel-Lucent introduced new signal processing software developed by Bell Labs that promises to shake up the business model for VDSL2.

The new ‘Zero Touch Vectoring’capability eliminates the need to upgrade every CPE in a copper node whenever the first customer opts for faster broadband access delivered over a VDSL2 vectored line.  Previously, a carrier choosing to deploy VDSL2 Vectoring was required to upgrade every modem on the network in order to properly handle the crosstalk elimination.

Alcatel-Lucent introduced the first commercial VDSL2 Vectoring solution in September 2011, delivering 100 Mbps over existing copper loop lengths of 400 meters.  VDSL2 vectoring uses digital signal processing to remove crosstalk between copper pairs in a bundle, similar to noise cancellation in headphones. From line cards at the central office or DSLAM, the system measures the crosstalk from all the lines in the bundle and then generates an anti-phase signal to cancel out the noise.  Alcatel-Lucent developed its own chipset and software.  The VDSL2 vectoring is delivered via  a 48-port Board Level Vectoring card, a 48-port System Level Vectoring card, and a Vector Processing card supporting up to 384 ports.

Alcatel-Lucent said it now has 6 commercial contracts for VDSL2 vectoring.  The first live network is with Telekom Austria, which is using the technology in a suburb of Vienna.

Dave Geary, head of Alcatel-Lucent’s Wireline activities, said: “Trials with leading service providers have shown that VDSL2 Vectoring can effectively deliver the kinds of speeds it promised, and we are now starting to engage in mass-market deployments. With our Zero-Touch Vectoring and other innovations we are eliminating the final barriers that service providers around the world have faced – enabling them to deliver higher bandwidths to more subscribers, now.”

Lantiq Samples System-Level Vectoring Chip

Lantiq announced first customer shipments of its VINAXTM IVE1000 System-Level Vectoring Engine chip.

The company said its new VINAX IVE1000 represents a major milestone for the deployment of vectoring in the field. The chip is an integrated ASSP solution suitable for volume deployment of system-level vectoring solutions supporting up to 384 VDSL2 lines.

The implementation supports full cancellation and partial cancellation of crosstalk in copper bundles. Specifically, Lantiq's VINAX IVE1000 uses advanced signal processing techniques to cancel Far-End Crosstalk (FEXT) between any of the VDSL2 lines in a copper bundle. This enables service providers to achieve 100 Mbps symmetrical and beyond, according to the company.
In addition, Lantiq said its technology enables up to 20% system power savings in a fully-vectored system (compared to non-vectoring) as a result of optimal balancing of transmission power.

The VINAX V3 enables “vectoring ready"? VDSL2 line cards (which support ADSL2/2+ through VDSL2 30MHz standards), requiring only a remote software upgrade when the VINAX IVE1000-based central vectoring card is added at the CO or in a local cabinet. Connected to a vectoring standard-compliant CPE device such as the Lantiq XWAY VRX200, this combination allows the implementation of a complete end-to-end vectoring solution. Lantiq’s XWAY VRX200 CPE device is “vectoring ready" today, as such only a simple software upgrade is necessary for full vectoring functionality.

Lantiq noted that is VINAX Vectoring System is compliant with and is capable of supporting all features defined in ITU G.993.2 (VDSL2), G.993.5 (G.vector) and ITU G.997 (G.ploam). The solution applies to all VDSL2 profiles and supports up to 384 VDSL2 ports by cascading multiple VINAX IVE1000 devices. This high level of scalability, coupled with the compelling features offered by the VINAX V3 chipset, results in a solution that is ideally suited to a wide range of applications such as MDU, MSAN and DSLAM.
