- Default Node (Healthy)
- Highlighted Node (Impacted)
Tier 1: Network Performance Issues (Customer Facing)
#1 High Priority
**Call Drop** / Weak Signal
Root Cause: Poor RSRP/RSRQ, **cell congestion**.
Handled by: RAN NPO
#2 Data Slow
4G/5G Data Speed Too Slow
Root Cause: **High cell load**, backhaul congestion.
Handled by: RAN NPO IP
#3 Critical Outage
Site Outage / Down Cell
Root Cause: **Power failure**, fiber cut, or equipment fault.
Handled by: RAN DWDM
#4 Voice Quality
VoLTE / Voice Quality
Root Cause: High latency, **jitter**, or missing IMS registration.
Handled by: RAN IP
#5 Transport Link
Fiber Degradation
Root Cause: **Low optical signal (OSNR)**, fiber bend.
Handled by: DWDM
#6 Service Access
Routing or DNS Problem
Root Cause: Incorrect BGP routing, **DNS failure**.
Handled by: IP Core
#7 Security Alert
Security / SIM Fraud
Root Cause: **SIM swap fraud**, phishing, malware traffic.
Handled by: SOC
#8 Billing / VAS
VAS Auto Deduction
Root Cause: **Auto-subscription** from third-party content.
Handled by: VAS
#11 High Latency
High Latency & Jitter
Root Cause: **IP Route Flapping** or Core Link Saturation.
Handled by: IP CoreNetwork
#12 Transport
Microwave Link Degradation
Root Cause: **Rain Fade** / Alignment Shift / Interference.
Handled by: Microwave NPO
#13 Core Failure
Authentication Failure
Root Cause: **HLR/AUC Database Sync Error** / MME Glitch.
Handled by: CoreNetwork
#14 Capacity Plan
Capacity Congestion Warning
Root Cause: **Inadequate Sector Split Planning** / Oversubscription.
Handled by: NPO RAN
#15 Deployment
New Site Integration Failure
Root Cause: **Mismatched DCN/IP Plan** or RAN Configuration.
Handled by: RAN IP NPO
#16 Security
Unexpected Traffic Spike (DDoS)
Root Cause: **DDoS Attack** Originating from Foreign IP.
Handled by: SOC IP
#17 DWDM Fault
Optical Channel Drift
Root Cause: **Laser Failure** / EDFA Noise Floor Increase.
Handled by: DWDM
#18 Revenue/Fraud
Premium SMS Abuse
Root Cause: High Volume of Suspicious Activity on a **VAS Short Code**.
Handled by: VAS SOC
#19 Mobility
Poor Handover Success Rate
Root Cause: **Overlapping Coverage** / Parameter Tuning Issues.
Handled by: RAN NPO
#20 Billing Critical
CDR/Billing System Error
Root Cause: **Diameter Interface Loss** / Mediation Failure.
Handled by: CoreNetwork
Tier 2: Operational & Ticket Handling Challenges
#1 Misrouting
Wrong Categorization
Cause: CSR/Helpdesk error, **CRM logic error**.
Impact: **Resolution delay**.
#2 Data Quality
Incomplete Ticket Info
Cause: Missing MSISDN/site ID, **CRM-NMS sync failed**.
Impact: Cannot investigate.
#3 SLA Risk
NOC Escalation Delay
Cause: **High ticket queue** or monitoring alert overload.
Impact: **SLA breach**.
#4 System Integration
CRM–OSS Sync Error
Cause: **API failure**, data mapping mismatch.
Impact: **Lost ticket** or duplication.
#5 Routing Logic
Wrong Team Mapping
Cause: Wrong configuration, **outdated org matrix**.
Impact: Misrouted tickets.
#6 Priority Mismatch
Severity Mismatch
Cause: **Human error** or unclear severity definition.
Impact: Wrong resource allocation.
