BT (NYSE: BT) will expand its up to 20 Mbps speed ADSL2+ to about 2.5 million homes and businesses, or 90 percent of the UK population by 2013, up from the 80 percent of homes it originally planned.
Having already upgraded telephone exchanges that serve over 17.6 million premises, BT will upgrade an additional 800 telephone exchanges to reach its new broadband expansion goal. Part of this new initiative focuses on extending broadband to more rural areas, meaning that BT will also upgrade over 400 Central Offices (CO), or telephone exchanges, that serve more than 900,000 rural homes and businesses.
"This is a significant expansion of our rollout plan and is further proof of our commitment to serve rural areas," said Alex Pannell, BT's director of product management.
The service provider said that it has "invested significant amounts" to install DSLAM equipment to support DSL just about 5,500 of its UK area COs.
Unfortunately, BT is the only broadband game in town for many rural dwellers. However, that scenario will change when competitive broadband provider TalkTalk (LSE: TALK) completes its own ADSL2+ LLU expansion from 80 percent to reach "nearly 90 percent of the population" sometime in 2012.July 29, 2011 — 8:31am ET | By Sean Buckley

VDSL Port Shipments Grow to Record Level in the First Quarter
EMEA and North America Account for Most Shipments
REDWOOD CITY, Calif. — According to a newly published report by Dell’Oro Group, the trusted source for market information about the networking and telecommunications industries, VDSL port shipments reached a record level in the first quarter of 2011, surging almost 50% over the year-ago period.
“With ADSL being a mature technology with limited bandwidth capabilities, many service providers are upgrading their networks with high-speed VDSL or PON equipment to enable new, high-bandwidth intensive services such as IPTV,” said Tam Dell’Oro, President of Dell’Oro Group. “In many situations, VDSL is also being used as part of all-IP network transformations that utilize multiservice access nodes and soft switches with the goal of decommissioning older TDM infrastructure,” Dell’Oro added.
The report also indicates that VDSL growth was led by shipments to EMEA, which almost doubled over the year-ago period and accounted for more than 60% of worldwide VDSL shipments. North America was the second largest region for VDSL, accounting for a quarter of total VDSL. The majority of these were purchased by AT&T to support its U-verse IPTV service, the largest fiber-to-the-node/VDSL upgrade project currently being deployed. Tuesday, June 7th, 2011

AT&T's Stephenson says its legacy DSL is 'obsolete'
Randall Stephenson, CEO of AT&T (NYSE: T), during this week's National Association of Regulatory Utility Commissioners (NARUC) summer meeting in Los Angeles, admitted that the copper-based DSL network that delivers its broadband data services is "obsolete."
Of course, AT&T's chief competitor Comcast (Nasdaq: CMCSA), which had its own EVP David Cohen speaking at the event right after Stephenson, wasted no time reporting on Stephenson's comments.
Sena Fitzmaurice, Vice President, Government Communications tweeted: "AT&T CEO: to chase comcast we built dsl, it is obsolete now."
Obviously, this statement is a shot in AT&T's foot in that DSL (VDSL2 for a growing amount of its U-verse customers) continues to be the dominant broadband vehicle for its customer base. Compounding the issue is that AT&T said earlier this year that it would start winding down its U-verse rollout, meaning that those customers that have not been upgraded yet probably won't be for a long time.
When AT&T was asked later by GigaOm to clarify Stephenson's comments, AT&T spokeswomaqn Mari Melguizo said he was answering a question from an audience member about how state regulators should think about new technology cycles when they are considering things like USF.
She added that Stephenson believes that new technology like DSL used to be amortized over a 10-15 year period, but that has shrunk to about 5 years now. Since DSL was introduced in the 1990s, it has been surpassed in speed by its U-verse product and Comcast's DOCSIS 3.0.
And much like how 4G wireless has surpassed the speeds and available applications on 3G wireless, Stephenson's main point was that new technology is being surpassed by the next generation much quicker than ever before. "We have millions of customers using DSL and remain fully committed to the technology -- even as we constantly look to bring innovation to the marketplace," Melguizo said.

AT&T: Bonded VDSL is here for real
AT&T's (NYSE: T) deployment of bonded VDSL--one that's seen various delays dating back to 2007--now appears to be on track.
Designed to be a response to cable's DOCSIS 3.0 drive, a Broadband DSL Reports post reports that AT&T will start rolling out pair bonded VDSL this week in certain markets and eventually throughout its entire 22 state territory. With bonded VDSL, AT&T will be able to reach more customers because they will be able to extend its U-Verse service an additional 1-2,000 feet from the Video Ready Access Device (VRAD).
This extended reach will enable AT&T to pass 30 million homes-a goal it previously missed because of modem chipset issues--by the end of next year. Even though AT&T made a recent claim that it could deliver 80 Mbps service, it looks like its bonded VDSL deployment is focused on expanding the reach of U-Verse not bandwidth speeds. VDSL with bonding can theoretically expand broadband data speeds, but chances are the enhanced bandwidth will be used for video with broadband speeds holding 24/3 Mbps for customers that are eligible for the service.
But even if AT&T is moving forward with its bonded VDSL plans, cable will still have the advantage over AT&T in terms of broadband speed. By comparison, Comcast's 50 Mbps DOCSIS 3.0 service is already available in 80 percent of its markets and it has been rolling out a 100 Mbps DOCSIS 3.0 service in select markets. To compete with cable's speeds, AT&T will likely have to consider leveraging new DSL innovations such as Dynamic Spectrum Management (DSM) and vectoring. July 16, 2010 — 10:10am ET | By Sean Buckley

Ikanos chips support 100 Mbps DSL
Ikanos has developed a new set of chips that support 100 Mbps DSL, based on a new standard that supports both channel bonding and vectoring.
Ikanos' new Fusiv Vx185 and Vx183 chips conform to the new G.vector ITU standard, which defines how to achieve 100 Mbps service over traditional copper lines, which by some calculations would be a tenth the cost of achieving the same transmission rates with fiber.
The standard covers bonding for increased rate and reach, ultra-low power and, ultimately, gigabit line rate performance.
These new devices add to Ikanos' NodeScale Vectoring architecture, which spans the central office, remote cabinets in fiber to the node (FTTN) networks, and now the customer premises.
The Fusiv Vx185 integrates support for bonding by natively interfacing directly to two integrated analog front-end devices, Ikanos said. This is designed to allow the coupling of two TCP (twisted copper pair) wires. Together, bonding and vectoring can be combined to push aggregate data rates up to 300Mbps, the company said.
The new Fusiv family of devices also includes the following features:
Full ADSL and VDSL2 support with a single hardware design
Support for all VDSL2 profiles and band plans for Asia, Europe, and North America – 8a, 8b, 8c, 8d, 12a, 17a and 30a
Support for ADSL2+, ADSL2, and ADSL standards
Support for all mandatory and optional features of VDSL2
Exceeds Broadband Forum performance requirements (TR-67, TR-100, and WT- 114)
Support for all wired or wireless networking technologies including Wi-Fi (single or dual-band concurrent modes), HomePNA, HomePlug, Multi-media Over Coax, and ITU G.hn
Integrated SATA interface for the easy addition of network attached storage devices
System level support for high performance IPv6
IPSec and Secure Sockets Layer (SSL) VPN implementation using on-chip cryptographic engines
John Quigley, president and CEO, of Ikanos, said G.Vector support "pushes VDSL performance to the 100 Mbps threshold and beyond at a time when service providers are looking for a cost-effective way to upgrade their existing copper networks in order to compete with DOCSIS 3.0 and FTTH technologies."
