New VDSL Subscribers to Quadruple by 2014

The number of new people subscribing to very-high-bitrate digital subscriber line (VDSL) service will nearly quadruple by 2014 as more competitors begin to ramp up their support for the technology, according to new research from IHS iSuppli.
The number of new annual VDSL subscriber additions will grow to 60.1 million in 2014, up from just 15.6 million in 2009. A total of 23.3 million new VDSL subscribers were added in 2010.
“The telco broadband market is undergoing a seismic shift,” said Lee Ratliff, senior analyst for broadband and digital home at IHS. “Newer technologies such as VDSL and fiber-to-the-home (FTTH) have begun to emerge, while interest is waning within the industry for traditional broadband technologies like cable and asymmetric digital subscriber line (ADSL).” Read more

TDS Telecommunications Corp. is rolling out faster Internet service — 25Mbps downstream/5 Mbps upstream — to customers in seven states including Georgia, Indiana, Michigan, New Hampshire, Tennessee, Vermont and Wisconsin. In the first quarter of 2011, TDS plans to expand service availability to 13 additional states.
For the first time TDS is leveraging VDSL2 over copper to offer the faster download/upload speed combination.
In related news, TDS also reduced the price of its 15 Mbps and 5 Mbps DSL speed tier from $54.95 and $49.95 per month to $34.95 and $19.95 per month respectively.

AT&T Deploys Bonded VDSL
Posted by Jesse Ward on Monday, July 19, 2010 · ·
In an attempt to extend the reach of its U-Verse services, AT&T has begun deploying pair-bonded very high bit-rate DSL (VDSL) in the last-mile, copper portion of its fiber-to-the-node (FTTN) network.
The technology — which bonds two copper wires together – extends the network’s reach an additional 1,000-2,000 feet in a neighborhood. The variety of DSL that AT&T is using, VDSL, has a useful range of around 3,000 feet from the video-ready access devices (VRADs) that are the fiber-fed nodes in the U-verse network.
AT&T initially announced its intention to deploy pair-bonding back in 2007, but was faced with unexpected delays along the way, including modem chipset issues. The technology was supposed to help AT&T compete head-on with the broadband speeds offered by DOSCIS 3.0 cable systems. However, AT&T now reports that pair bonding won’t increase the bandwidth the telco can deliver over the network. Instead, the telco plans to use the technology to enhance its reach, offering video to more subscribers.
