Enhancing Network Resilience in Complex Systems

• 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.

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.

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:

1. 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 and effect of each issue. To ensure our clients’ systems operate optimally with minimized downtimes and costs, we used a proactive and systematic problem-solving approach:

• Assist our client in classifying alarm types based on severity, thus facilitating execution based on priority;
• Adopted Root Cause Analysis (RCA) to identify the underlying causes of alarm incidents and immediate solutions to remedy.


2. Power Backup Optimization

In Indonesia, there’s a significant challenge involving electricity reliability that often causes network outages. To optimize power support, our solution involves:

• Close coordination with PLN on blackout schedules to prepare efficient backup power support;
• Analyze historical patterns to gain strategic insights into power outage behavior;
• Strategic placement of backup power based to maximize backup power utilization;
• Streamlined distribution of power backup units to ensure optimal support in high-usage areas and save costs in low-usage areas.


3. Managing Large-Scale Outages

Among the many types of equipment damage, fiber optic cuts that often stem from intentional vandalism or damages during construction pose a significant threat to network availability and a large-scale network outage. To minimize such events, we:

• Finding workaround solutions to restore services as soon as possible;
• Collaborate with our client to deploy field supervisors to oversee public construction;
• Close coordination with field supervisors of fiber optic providers in safeguarding fiber optic networks to ensure uninterrupted and reliable network service.
