As one of the world’s largest network service providers, Norway’s Telenor must constantly upgrade its systems to stay on top. The company runs networks in 12 countries and operations in 29 more, and it has a market capitalization of roughly $38 billion. But it must keep its operations modern to maintain its position, so last year the company decided to upgrade its access network so it could deliver ultra-broadband services and improve the customer experience with ADSL2+ and VDSL2 technology.
Deployment of the upgrade currently is underway, and Telenor expects to have its 500,000 DSL lines migrated to the new VDSL2 platform by 2015, according to a recent case study, Telenor Achieves Competitive Advantage In Ultra-Broadband, on the rollout.
To efficiently deliver ultra-broadband services, however, Telenor needed a way to determine which of its existing DSL lines could be upgraded to VDSL2 without issue, and which ones needed additional infrastructure changes. Further, according to the case study, the company wanted to be able to provide DSL subscribers with the realistic attainable speed they could expect to receive if they upgraded to VDSL2.
Alcatel-Lucent’s Motive Network Analyzer – Copper has helped Telenor meet those goals.
The Motive Network Analyzer integrates line testing, diagnosis and optimization, helping operators ensure that DSL lines meet quality and stability requirements to successfully deploy high-speed Internet and triple play services.
One of its features is its Upgrade Predictor, which allows the operator to see how well the technology will work on existing infrastructure, and where improvements might be needed. Upgrade Predictor takes snapshot views of each individual DSL line based on values obtained from customer premises equipment (CPE) and the DSL access multiplexer (DSLAM) over a period of weeks. Telenor then could predict what needed to be upgraded and when.
The solution also offers dynamic line management, ensuring the best profile is assigned to the line in combination with its service. Using a real-time and per-line approach, DLM automatically monitors the condition of each of the lines in the network, and uses a variety of factors to optimize speed and preserve stability.
“Before Upgrade Predictor, we used tables that showed the line length from the DSLAM to the customer premises to determine if the customer line was
a good candidate for upgrade,” noted Foyn Johannessen in the case study, director of telephony & broadband at Telenor Norway.“A the end of the day, the Motive Network Analyzer, together with our total upgrade of infrastructure, has given us a real competitive advantage,” Johannessen said. “We can offer ultra-broadband to more subscribers, know that it’s going to work, and that the customer experience will be excellent. This helps us to reduce churn and really compete and win in the marketplace.”
