MILPITAS, CA - JDSU announced a triple-play service quality test suite for the HST-3000 Handheld Services Tester and T-BERD/MTS-4000 Multiple Services Test Platform. Using the JDSU Class of Service (CoS) test suite software option, field technicians can simulate real-world triple-play service use at the customer site, enabling the most effective analysis and troubleshooting of triple-play services running at the same time.

Traditionally, triple-play service testing involves separate, isolated actions – performing data tests, making VoIP calls, or checking IPTV channels. Today's challenge is that triple-play services are generally not used serially, particularly in the home: One person may be watching television while another person is downloading a large file and a third person is talking over the VoIP line. Each application has its own specific quality-of-service requirements, all have varying bandwidth demands and competing demands may affect the quality of individual services.

Testing individual applications may not reveal problems that will be seen with mixed application traffic flows. The CoS test suite, on the other hand, can eliminate service callbacks related to problems that cannot be detected using single-application testing.

"Service providers worldwide offer truly innovative triple-play services to their customers, but the paradox is that many are facing service issues associated with the demand for these groundbreaking, high-bandwidth offerings," says Jim Nerschook, vice president and general manager in JDSU's Communications Test and Measurement business segment. "The JDSU CoS test suite helps service providers meet the quality demands of their customers and ensure reliable triple-play services by allowing a technician to perfectly replicate and troubleshoot customer environments."

Specifically, the JDSU CoS test suite enables the simultaneous testing of multiple services running over multiple VLANs at the same time. During the test, technicians can view all services in use, as well as a graphical depiction of bandwidth across all of them. This helps the technician identify and resolve environments where one service may be impacting the performance of another. The new features also enable on/off control of all services from one screen. The technician is therefore able to do exactly what the customer may be doing, offering an ideal test/traffic simulation and troubleshooting environment.
