- Resolve link failures, bandwidth constraints, optical impairments and synchronisation issues while maintaining backhaul and aggregation availability.
Service Flow & Customer Impact Analysis
- Assess and map network faults to customer impact across mobile and enterprise services.
- Own VIP and critical customer escalations through service restoration.
Monitoring, KPIs & Tools
- Monitor throughput, latency, packet loss, utilisation and session drops using EMS/NMS, Netcool and performance tools.
- Use alarms, logs, traces and telemetry for fault correlation and deep-dive analysis.
Automation & ANO Enablement
- Drive fault detection, correlation, self-healing and closed-loop automation aligned with ANO principles.
- Support AI/ML-driven insights for proactive operations and reduced manual intervention.
Customer Handling, Governance & Communication
