When it comes to bringing triple-play services to businesses and residential customers, DSL is still the most widely deployed broadband access technology across the globe. This is not surprising, given that the copper plant is one of the most economical options available for the delivery high-value broadband services.
However, in the wake of the recent explosion of over-the-top (OTT) services and the increasing demand for faster, higher-quality video content, operators need to increase the available speed of xDSL services running over the copper last mile to make the most of existing legacy infrastructure.
But to truly capitalize on your existing copper plant, you need to guarantee service levels and customer expectations by conducting thorough qualification and verification of DSL services before, during and after the service has been delivered to the customer.
Meeting this objective is dependent upon identifying and quickly responding to service problems when they arise. One common issue that gives headaches even to expert technicians is Impulse noise. To effectively troubleshoot -impulse noise issues, you need to first understand how to detect it and moreover, assess its impact on the network over time. The challenge; however, lies in the fact that impulse noise is by nature much harder to detect and analyze that traditional interference, and unreceptive to traditional troubleshooting methods.
