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
