Autonomous Network L4 isn’t a science project—it’s the next operating model for Tier-1 telcos. This guidebook shows CTOs and CNOs how to reach Level 4 autonomy in high-value scenarios by 2025/26, using Cyient’s Intelligent Network Modernization playbook aligned to the TM Forum AN Maturity Model and Four Pillars. Inside: what L4 really means (intent-based execution, closed-loop assurance, cross-domain coordination), where to start, how to prove value (KCIs/KEIs/KBIs), and an assessment-led roadmap plus modular architecture to scale with minimal disruption. Expect 40% fewer critical alarms, 15% lower energy use, and MTTR <15 minutes. Download now to turn pilots into production autonomy.

Key takeaways

• L4, clearly defined: intent-based execution + closed-loop assurance + multi-domain self-coordination across RAN, Core, Fixed, Transport, and IP.

• Start where ROI is real: prioritize High-Value Scenarios across service assurance, fault/change automation, quality optimization, and energy optimization.

• Operationalize at scale: baseline first, track KCIs/KEIs/KBIs, and build an open, modular foundation for Intelligent Network Modernization using TM Forum Open APIs.
