Enhancing Network Resilience in Complex Systems

Highlights

In the dynamic landscape of large telco enterprises facing disruptive system challenges, Triple-E supports one of Indonesia's leading operators in managing the network operation of 17,000 BTS towers in Sumatera.
With the regular occurrence of external threats affecting telco equipment, preventive maintenance is crucial in maintaining network stability and resilience to overcome potential issues.
Our implemented strategies that aim to mitigate future challenges resulted in a reduction of support requests and optimized system performance.

The Challenge

While routine maintenance is essential to ensure tower longevity and compliance, telco companies contend with unpredictable elements such as severe weather conditions and human threats, leading to issues like equipment damage, electricity outages, vandalism, theft, and equipment hazards. The result of services downtime can be very costly, especially for leading network operators like our clients, whose web of services spans over a thousand transmission tower sites. In cases like this, we need to prevent problems before they start and deliver high-quality execution to ensure network resilience.

Our Solution

At Triple-E, we carry out corrective and preventive maintenance together with customized solutions tailored to the client's challenge. To pave the way for uninterrupted network services, our execution involved:

Alarm Prioritization

Managing alarms that cause service disruption is our top priority, yet the complexity of repetitive and false alarms makes it challenging to identify the impact of each issue. Our proactive, systematic approach:

Classifying alarm types by severity, to prioritize execution
Root Cause Analysis (RCA) to identify underlying causes and immediate remedies

Power Backup Optimization

Electricity reliability is a significant, recurring cause of network outages in Indonesia. Our solution:

Close coordination with PLN on blackout schedules
Historical-pattern analysis for strategic backup placement
Streamlined distribution of backup units by usage area

Managing Large-Scale Outages

Fiber optic cuts — often from vandalism or construction damage — pose a significant threat to availability. To minimize such events:

Fast workaround solutions to restore service
Field supervisors deployed to oversee public construction
Close coordination with fiber providers' own field supervisors
