PathTrak™ Return Path Monitoring

PathTrak is the world’s No. 1 selling HFC Return Path Monitoring System, with such wide ranging adoption that in conversations the name “PathTrak” is commonly used and understood to mean “return path monitoring system.” This market influence is based on the superiority of the PathTrak system, which monitors the return path spectrum for impulse noise, ingress, or abnormal level variation, and now individual live modem upstream performance. In addition, customers trust knowledgeable, helpful JDSU Sales and Support to ensure that they get the optimum benefit from PathTrak system deployment.

PathTrak is the only return path monitoring system that offers QAMTrak™ and MACTrak™ Technology. The QAMTrak analyzer speeds troubleshooting by displaying a variety of upstream QAM signal measurements simultaneously on an easy to read a dashboard display. MACTrak enables the tech to isolate the view to a specific MAC address with codeword error detection analysis of in-band/in-service cable modem or DSAM packets to indicate in real-time impairments that are affecting subscriber services. In addition to providing browser-based access to PathTrak and more extensive reporting and analysis, WebView enables the Field View QAM option on the DSAM to facilitate troubleshooting customer affecting return path issues.

Benefits

  • Opens a new window of troubleshooting capability by allowing analysis of active bursty DOCSIS 3.0 upstream carriers with unique QAMTrak technology
  • QAMTrak analyzer increases signal performance analysis effectiveness by revealing linear and non-linear distortions, not just simple ingress
  • Provides a more accurate view of node health by evaluating spectrum AND carrier quality
  • Improves the efficiency of technical operations with MACTrak, which reveals the impact of impairments on customers’ services and ranks nodes based on performance (NPI) Node Performance Index: Fix the most critical problems first
  • Lower MTTR (Mean Time To Repair) by isolating problems to specific MAC addresses with MACTrak
  • A long lasting investment, the system is scalable, designed to grow as your network grows
  • A tried and true solution – over 400,000 HFC nodes worldwide are monitored and maintained with PathTrak products

Applications

  • Troubleshoot nodes faster to reduce MTTR and increase workforce efficiency
  • Determine root cause of impairments using traditional spectrum and MACTrak technology before rolling a truck
  • Demodulate live DOCSIS QAM carriers transmitted from DSAMs in the field to troubleshoot in-band impairments
  • Verify that you’ve really fixed the problem with deep QAM analysis capabilities and codeword error detectio
  • Use Field View QAM with DSAM for in-band upstream trouble shooting and reduce this to a one person job
  • Use Field View™ with SDA and DSAM field meters to quickly locate ingress, the most common impairment
  • Insert carriers from the field to troubleshoot linear and non-linear impairments such as laser clipping, group delay and micro-reflections
  • View performance history to understand transient problems to roll a truck at the right time to find and fix the issue
  • Reduce trouble tickets and customer churn by identifying problems before they affect customer experience
  • Rank nodes according to customer modem performance, with convenient web-based reports for proactive maintenance
  • Easily and quickly detect impairments such as fast impulse noise, ingress, CPD, and laser clipping on all nodes 24/7
  • View live spectrum, QAMTrak analysis and a wide array of reports conveniently via the web

Key Features

  • Node ranking based on upstream health – spectral and in-band
  • Effective alarms and intelligent alarm management
  • Economically scalable system
  • Remote spectrum analysis
  • Remote QAM analysis
  • Supports Field View QAM
  • Provides detailed packet-level information such as:
    • Equalized and unequalized MER
    • Correctable and uncorrectable codeword errors
    • Group delay
    • Micro-reflections
    • In-band frequency response (ripple)
    • Ingress under the carrier display and metric
    • Impulse noise indicator and metric
    • Constellation
    • Carrier-level fluctuation
