DSAM Now Conducts Digital Quality Index (DQI) Measurement; PathTrak(TM) adds Forward Path Monitoring MILPITAS, Calif., June 19 /PRNewswire-FirstCall/ -- JDSU today introduced two innovative, powerful capabilities to its industry-leading portfolio of communications test and measurement solutions that address the complexities of bandwidth-intensive digital video, VoIP and high-speed data services deployment for cable operators. These additions help reduce costs and instances of truck rolls while lowering customer churn and instilling confidence that advanced services will be delivered with quality. JDSU's digital service activation meter (DSAM) now performs digital quality index (DQI) measurements, enabling providers to quickly and accurately identify network impairments that affect digital services such as high definition TV. JDSU's PathTrak hybrid fiber coaxial (HFC) test and monitoring portfolio now includes the PathTrak Forward Path Monitoring Solution. This new addition monitors and trends performance at remote cable hubs and headends to quickly identify issues and remotely segment radio frequency (RF) performance. Both introductions prevent unnecessary truck rolls, increase workforce efficiency and ensure service quality. JDSU will display these new features, as well as its entire portfolio of award-winning test and monitoring solutions for cable operators, at SCTE's Cable-Tec EXPO, June 19-22, Orlando, booth #1286. "JDSU continues to ensure our test and measurement instruments and systems give operators a proactive weapon against network challenges that can harm a consumer's experience," said Kevin Oliver, vice president of marketing for JDSU's Cable Networks business unit. Oliver added, "Responding to operators' demands for simpler tools that help field technicians locate network issues, the DSAM's new DQI results are easy to interpret and detect the slightest digital signal impairments. The automated and remote design of PathTrak's Forward Path makes it a tool of great value, saving operators time and money as they continue to maintain high performance digital networks." DQI: Instant, Comprehensive Digital Stream Analysis for Service Quality DQI is a ground-breaking digital quality measurement capability that an industry panel recently noted for "its ability to provide the 'heightened awareness' necessary to completely troubleshoot a problem." Now available exclusively on JDSU's DSAM, DQI detects and responds to problems in the distribution plant faster and earlier than current industry standards. DQI has more power than modulation error ratio (MER) and bit error rate (BER). MER and BER only sample a small portion of the stream, are slow to respond to intermittent issues and are often too confusing for the average technician. The data gathered by the DQI is raw, digitized data directly from the demodulator that is comprised of analog components in digital form representing the signal-to-noise ratio (SNR) of the received Quadrature Amplitude Modulation (QAM) carrier. Its measurements are represented by an easy to understand index rating from one (lowest quality) to ten (highest quality), providing an instant indication of the overall quality of a QAM digital stream. PathTrak Forward Path Monitoring: Digital TV, VoIP, High-Speed Data Quality JDSU's PathTrak Forward Path Monitoring Solution includes the RSAM-5700 remote analyzer probe. It monitors unmanned hub and headend sites to proactively and economically monitor the forward path multiple downstream analog and digital channels used for digital video and triple-play services, quickly and remotely identifying forward path problems. Technicians can now avoid driving to remote or unmanned locations to manually test networks. Using a web-based interface for easy viewing on DSAM meters (requires DSAM Browser option) or PC Internet browsers, users can quickly view, analyze and segment network performance from just about anywhere. The PathTrak Forward Monitoring System continuously monitors QAM and analog RF, including MER, BER, and level, to ensure quality VoIP, VOD and high-speed data services.
