New DTS-330 Feature, on Display at IBC 2006, Conducts Early Stress Testing of Triple-Play Services Network Equipment to Ensure Quality Service MILPITAS, Calif., Sept. 8 /PRNewswire/ -- JDSU (Nasdaq: JDSU; and TSX: JDU) today announced the addition of a new capability to its industry-leading and award-winning digital and IP video test instrument, the DTS-330. Called JDSU's SimulSource IP Video Generation Application, this software tool helps network equipment manufacturers (NEMs) verify equipment for IPTV and other triple-play service deployment by identifying and troubleshooting issues or improving performance before it is shipped. It also supports network operators in their research and development (R&D) labs by stress testing equipment -- including IP transport equipment, edges devices, routers, switchers and IP multicasters -- to ensure reliability and efficiency before turning up advanced network video services. The new SimulSource IP Video Generation Application, in addition to the JDSU's complete portfolio of IPTV and IP video test and measurement solutions for the broadcast industry, will be on display at IBC 2006 in Amsterdam, September 8-13, stand 1.215. The ability for NEMs and operators to conduct stress test and verification on their own allows them to adjust, troubleshoot, and improve performance before equipment is deployed in the network. SimulSource IP Video Generation Application supports this by generating hundreds of IP video test streams typically involved in a network carrying IP Video services, allowing NEMs to verify and stress test equipment using many types of encapsulation and signal layer analysis (MPEG, upper and lower layer protocol) for a full view of the equipment's performance. With SimulSource, the DTS-330 can also perform testing/verification of both the output and input of multiple aggregated IP video streams over a Gigabit Ethernet (GbE) pipe, enabling peak performance and the transmission of the maximum amount of allowable data. "In today's competitive environment where quality of service is a significant factor in successfully delivering services such as IPTV, assuring the performance of network equipment is a high priority for providers and NEMs. JDSU is launching SimulSource IP Video Generation Application to help ensure that network equipment is tested and analyzed early and in the best shape possible," said Sudeep Bose, JDSU's global product manager for the digital video test and measurement product line. "Its ability to validate and stress test equipment gives customers confidence that the equipment is performing optimally and able to effectively support the delivery of exceptional quality IPTV service when it ships." More about the DTS-330 at IBC 2006 JDSU's DTS-330 is a proven test product, deployed throughout the industry to ensure efficient and reliable deployment of advanced digital and IP video services, such as video on demand, IPTV or digital video broadcast, for satellite, broadcast, telecommunications or cable providers around the world.
