    ITU releases DSL service specifications

    AS part of its plan to widen the availability of broadband Internet in 2005, the International Telecommunications Union has released service specifications that would allow DSL service providers worldwide to offer faster broadband connection.

    The standards -- identified as G.Bond or G.998 -- were released late December. These combine two or more traditional copper telephone lines used for DSL to transport data from the service provider to a single subscriber.

    This means that consumers or businesses with more than one telephone line can maximize their bandwidth using different lines. ITU said this process was not possible in previous models of DSL. increases the data rate in proportion to the number of lines that are bonded. For example, two bonded lines will double the data rate for both upstream and downstream connection. Three bonded lines will triple the data upstream and downstream rate, and so on.

    Moreover, the new ITU specifications are independent of the current DSL technologies such as ADSL and VDSL.

    The specifications guarantee the triple play of voice, video and data services over DSL. For instance, video -- which requires very high bandwidth -- has always been the most difficult to deliver especially in areas far from telephone exchanges.

    The concept of combining telephone lines, also known as “bonding,” is common in countries where two or more lines are connected to both business and household users.

    Yoichi Maeda, chairman of the ITU’s study group that prepared the standards, said that bonded DSL lines are the key to offering consumers bandwidth-hungry applications such as video and gaming and is an ideal way to offer higher bandwidth to businesses.

    The standards are said to be crucial as the push toward multimedia Internet services becomes apparent.

    In addition, multiple wire solutions, where wires are already in place, are often seen as a cheaper solution to rolling out new fiber networks. It also leverages on existing infrastructure, while maximizing customer service.

    Philippine carriers such as the Philippine Long Distance Telephone Co., BayanTel and Globe Telecoms have been aggressively expanding their DSL connections. If they are to adopt the ITU specifications, they will be able to expand multimedia services using newly installed DSL lines, as well as telephone lines previously deployed prior to DSL.

    However, DSL still accounts for a small percentage of the three carriers’ revenues.
