Agenda
• Telecom drivers - integrated fault management
• Primary use case – physical fault correlation
• Telecom NDT- a platform for analytics
• Usability focus - Supporting the operator & the value of automation
• Showcase the Proof of Concept

Business drivers
• Reduce fault induced operational costs• Increased competition and customer service expectations
• Reduce response times and service downtime• Often governments are mandating targets for fault correction and service downtime
• Stay competitive with technology changes• Utilise analytics and machine learning to enhance fault predictions and accuracy
• Leverage combined value across all utility asset data• Integrated network asset data has a greater value than sum of the parts

Physical fault workflow – key aspects
• Multiple systems interaction• Fault events raised from fault detection system
• Network fault distances and likely at-fault assets are searched from PNI+PRM
• Follow up instructions and work orders issued from WA and PNI
• Manual search for assets at fault• No automation with limited correlation capacity
• Manual context transfer between systems
24 October 2018Telco NDT - Analytics in Fault Management 6
• Integrated and automated workflow• Data exchanged and control passed via micro-
services
• Analytics do most of the work• High levels of system automation
• Benefit from machine learning for automated dispatch
Effective operator - Business Needs
• One app and one system for physical fault management• Aggregate and summarise relevant data that requires operators attention
• Tools made for ease of use and efficiency• Focus operators attention on events that require their intervention
• Drive the process for the operator
• Effective and consistent fault management• Machine learning matched with heuristics for effective fault resolution
• Able to classify and order incoming fault events

Physical Fault Management
Proposed solution – key concepts
• Telecom NDT – more than sum of the parts
– Aggregates relevant network data
– Micro-services to maintain the data
– Micro-services for further system integration
• Analytics engine – “the brains” of the system
– Correlate for common asset at-fault
– Calculate probability of suggested solutions
• Operator’s App – streamlined usability
– Help the operator by focusing on manual tasks
– In 80-20 world reduce the workload through design
924 October 2018Telco NDT - Analytics in Fault Management
Proposed solution – key components
• Predix services – Intelligent Mapping Service – Asset data visualisation and inspection properties
– Predix Asset - Stores reduced relationship between PRM RFS and physical assets
– User Authentication and Authorisation – Maintains system security
• Client application– Physical Fault Management WEB App
– Predix UI framework – common look and feel
– Asset Correlation Engine
• System interfaces– Dispatch system microservice
– Correlation engine microservice
1024 October 2018Telco NDT - Analytics in Fault Management
Proposed solution – contributing systems
• Physical Network Inventory (PNI)– Enables asset data visualisation and essential asset properties
• Physical Route Manager (PRM)– Resource Facing Service provide essential link to physical assets
• Fault Events Monitoring– Fault RFS events and measured fault distance enable effective asset correlation
• Workforce Automation– Correlated physical asset faults with GIS maps and connectivity provide essential input to field
fault resolution scenarios

PRM Route – Resource Facing Service (RFS)
• PRM extends PNI data model with a concept of a route:
• Point-to-point connection in a fiber network
• Can use one, two or more parallel fibers
1224 October 2018Telco NDT - Analytics in Fault Management
PRM Route – Resource Facing Service (RFS)
Fibers/ports are explicitly assigned to a PRM Route
Routes start/end at active device or fiber distribution panel

Automated fault correlation & dispatch
• RFS faults auto-consumed– The app is displaying processed faults
– The app is displaying correlated proposed failure points
• Analytics engine – operator’s assistant– Analytics engine correlates for physical assets in common.
– Heuristics to determine probability of proposed asset faults
– Modular analytics
• Support for automated crew dispatch– Micro-services for fault management integration
– Micro-services for Workforce Automation integration

Physical asset fault correlation
Benefits to Telco's
• Increased operational efficiency– Automated heuristics based fault classification
– Manual operator’s focus on fewer more complex alarms
– Dispatch artefacts can be auto generated
• Reduced demand for truck roll– Due to higher level of fault correlation we expect fewer truck roll for exploratory fault
identification
• Increased operational system integration– Use correlation micro services to integrate with Workforce Automation
– Increased system and process monitoring
