The XPERTrak Service Dashboard provides visibility into the worst performing nodes in an operator's system using adjustable QoE metrics. Node-level roll-ups are presented with drill-down granularity to per-subscriber QoE metrics. Trending displays are available to quickly identify chronic offenders vs. one-time occurrences, and alarm status is displayed to flag nodes where immediate action is warranted. Now service issues can be identified before subscribers call and repairs prioritized based on service impact
Beyond just pointing out the worst nodes, XPERTrak correlates impacted subscribers with detected plant impairments to pinpoint which specific issues to address to maximize customer QoE improvement and reduce churn. VIAVI draws on decades of experience to define appropriate impairment correlations and corresponding corrective actions. This allows sending the right person at the right time to fix the issue versus requiring extensive field diagnostics. By making QoE metrics readily available to field technicians on the tools that they commonly use they can confirm that any fixes applied truly addressed customer impact, not just improved physical layer symptoms.
Proactive Network Maintenance (PNM) capabilities have been proven as an efficient method for identifying and remotely locating impedance mismatches in cable networks, often before subscriber services are impacted. XPERTrak has overcome the two primary challenges that have prevented operators from gaining maximum value PNM – tool complexity and focus on issues impacting subscriber services. Many PNM tools have proven too complex for typical users to get value from, but by providing intuitive displays showing just what is needed to solve problems XPERTrak has moved PNM from being a science project for a handful of Engineers to a tool usable by the masses. By overlaying QoE impact per-modem for PNM-identified groups, XPERTrak can identify which issues need fixed now vs those which should be deferred for future repair.
Once you know where to roll a truck to, you still have find and fix the plant issues. Upstream ingress is the most common issue for technicians to address, and via PathTrak hardware support XPERTrak provides best in class live spectrum analyzers to expedite this process. Technicians can view both local and combined spectrum on their VIAVI field meters using Field View capabilities enabling single-person workflows. Mobile-friendly displays make spectrum and all other XPERTrak capabilities readily accessible out in the field where they are needed most. Virtual spectrum and QAMTrak analyzers provide continuity of critical real-time test capabilities during the DAA transition using common processes and user interfaces for legacy and DAA nodes. VIAVI leakage system integration further accelerates field find and fix activities including final localization of PNM-identified issues. PathTrak established its reputation as the go-to tool for field find and fix over 20 years ago, and XPERTrak continues to expand upon this legacy.
Distributed access architectures (DAA) such as Remote PHY are disruptive to HFC monitoring and maintenance practices. Most MSO's plan to implement more than one type of DAA and use multiple vendors, and it will be challenging to develop standard processes to monitor and maintain networks with this highly heterogeneous mix during the typical 5+ year transition period. XPERTrak provides continuity of test for upstream capabilities including live spectrum and QAM analysis, monitoring/alarming, performance history, and sweep using the same field meters and processes used for legacy nodes. Technicians using PathTrak to maintain and troubleshoot traditional nodes today can seamlessly transition to the DAA equivalents in XPERTrak with no learning curve or process changes.
XPERTrak provides live heatmap spectrum analysis from both PathTrak hardware and virtual sources, addressing the challenge that wider OFDM-A carriers create in the common task of ingress remediation. DOCSIS 3.1 provides significant enhancements to plant health visibility, and XPERTrak is the first solution available to take full advantage of these. DOCSIS 3.1 metrics are interwoven into existing XPERTrak QoE monitoring algorithms enabling most accurate identification of issues creating the greatest churn risk in an operators network. Summary views give a quick picture of network health based on OFDM profile distributions to drive proactive actions, and an optional DOCSIS 3.1 Analyzer is available for on-demand troubleshooting of per-modem issues. Only XPERTrak provides the full set of capabilities needed to effectively monitor, maintain, and troubleshoot DOCSIS 3.1 networks.

At the micro level, managers generally have a good handle on which issues are the most urgent to work for their specific area, but each area working their local issues alone will not move the needle on regional or enterprise metrics. XPERTrak and NITRO Business Intelligence provide broader visibility into the higher-level trends and issues that can have a greater impact on the KPI's that drive your overall business. Spotting these trends and drilling down to find systemic root causes allows resource deployments to deliver the highest possible ROI.
Most organizations today are not lacking in data, but are starved for meaningful insight realized from this data. True value is delivered when data from your internal systems, XPERTrak, and 3rd-party sources can be combined and analyzed to identify truly needle-moving initiatives. XPERTrak and NITRO Business Intelligence are different from one-size-fits-all business intelligence platforms in that they are built specifically for HFC and PON operators by experts with decades of domain knowledge. XPERTrak leverages industry leading PathTrak hardware plus inputs from VIAVI signal leakage gear, field meters, and fiber monitoring systems to deliver unprecedented system and subscriber health visibility. NITRO Business Intelligence then uses advanced domain-specific analytics to combine this with other sources to help identify the true issues driving your KPI's and helps you identify and track initiatives to improve them.
The drive from Marketing to launch new services faster is relentless, but launching these before everything is ready can backfire. Launching before an area has adequate CPE/CCAP to support can lead to disappointing returns, and if the launch causes QoE issues the resulting churn can more than negate any revenue gains. XPERTrak provides visibility into which areas are good targets based on sustained QoE performance, and NITRO Business Intelligence can combine CPE deployment data to paint a true picture of deployment readiness. Dashboards and reports are available to track the deployment of the new services plus the subscriber QoE during and after the launch to ensure there are no negative impacts.
The best data aggregation and analytics capabilities are of zero value if the results cannot be viewed and acted upon. XPERTrak displays and user interfaces have been designed and continually improved based on extensive time in the field with our customers and listening to their direct feedback. API's are available to enable integration of XPERTrak data into MSO internal systems, but that often requires involvement from your scarce IT resources. NITRO Business Intelligence was architected to address this by enabling rapid customization to meet your exact business needs by working collaboratively with our domain experts – and not requiring any involvement from your IT teams. When new reports or tweaks to existing reports are needed to support new initiatives, trust VIAVI to deliver quickly and with minimal effort required on your end.
Broadband service provision infrastructure (CCAP ports, CPE, etc) is a major CAPEX budget item, even small reductions in this category can have a meaningful impact on overall profitability. With XPERTrak, operators can get more bandwidth from their deployed infrastructure through improved network performance. Just a 4dB increase in upstream SNR can net ~50Mbps of upstream capacity for a 31MHz OFDMA carrier – potentially eliminating or deferring the need to split a node. XPERTrak helps operations teams to identify, find, and fix the issues that are not only impacting subscribers but degrading network performance.
The XPERTrak Service Dashboard provides visibility into the worst performing nodes in an operator's system using adjustable QoE metrics. Node-level roll-ups are presented with drill-down granularity to per-subscriber QoE metrics. Trending displays are available to quickly identify chronic offenders vs. one-time occurrences, and alarm status is displayed to flag nodes where immediate action is warranted. Now service issues can be identified before subscribers call and repairs prioritized based on service impact
