Portugal Telecom, the leading operator in the Portuguese telecommunications market, will use DS2’s UPA-compliant 200Mb/s Power line technology to offer a remotely managed, multichannel IPTV service over power lines or coaxial cable that substantially reduces installation time and costs.

Portugal Telecom's IPTV subscribers can opt to install up to three set-top boxes (STBs). The service supports simultaneous streaming of one HD channel and two SD channels on multiple televisions in the home.

Portugal Telecom's subscribers can install their STBs anywhere in their homes, without the need for any new wires, and can use either the home coaxial network or the existing electrical wiring for IPTV content distribution.

Service providers deploying IPTV networks face significant problems to distribute IPTV services to every room in a subscriber’s home. Most homes do not have the cabling required for reliable IPTV distribution, and the option of installing these new cables in each home is very expensive and disruptive for the consumer. Wireless technology (802.11-based) does not have the bandwidth or the reliability required to carry HD video and suffers from interference problems in dense urban environments. DS2's 200Mb/s Power line technology provides a robust and secure connection using the existing electrical wires for the distribution of multiple IPTV channels throughout the home, even in densely populated areas.

DS2 technology reliably delivers multiple TV channels simultaneously, and has enough bandwidth to support HD services. In addition to guaranteed bandwidth, customizable Quality of Service (QoS) and reliable operation, only DS2-based solutions the support the DSL Forum's TR-069 remote management protocol, a key feature for network management and control.

UPA-compliant Power line technology has helped to make Portugal Telecom's offering more attractive and convenient to consumers than competing satellite or cable TV services. During 2008, Portugal Telecom plans to increase its subscriber base by more than 340 percent.
