Qwest is testing bonded DSL to gauge the viability of the technology.

Though the company recently ruled out offering TV service over its own network, DSL bonding could achieve transmission rates sufficient to support simultaneous video, voice and data services, according to a report in the Rocky Mountain News.

Even though Qwest has no plans for IPTV in its immediate future, it has still budgeted $300 million this year to deploy more fiber in select markets to enable the company to accelerate its top tier of DSL.

DSL speeds are highly dependent on the length of copper loops from the central office to subscribers' homes. Simply running fiber deeper should enable Qwest to achieve a maximum of about 20 Mbps with its DSL service. With channel bonding, the company can expect to boost DSL rates to 35 Mbps or more.
