Legacy Geospatial Replacement: Migrating OSP & FTTH Planning to Service-Aware Digital Twins

Stop drawing lines on maps; start managing a live, unified infrastructure.

If your GIS-based engineering software is being sunset, don’t replace it with another desktop solution. Upgrade your Physical Network Inventory (PNI) to a modern, open-source web platform. With a built-in digital twin, the platform empowers engineers to plan, simulate, and optimize in real time, ensuring your physical assets, power, and services act as one. Preserve your data, eliminate costly licenses, and embrace secure, high-performance, browser-based operations.

Leave the Limitations of Legacy Architecture Behind

Migrating decades of complex spatial data, geometric networks, and connectivity models is one of the biggest challenges in modernizing network planning. With proven expertise in legacy ESRI ArcGIS environments, Comarch Communictions helps securely extract, cleanse, and migrate even the most complex geospatial data without disrupting ongoing operations.

Instead of replacing your current environment with another heavy solution, your data can be preserved and transitioned into a modern, secure, web-based geospatial layer. Built on an open-source, map-agnostic architecture, it enables real-time processing and lays the foundation for a true digital twin that connects physical, logical, and service layers in one consistent view.

This approach allows you to reduce reliance on desktop tools and proprietary databases while improving performance, lowering TCO, and preparing your network for continuous evolution.

Manage rack space, floor space, ducts, manholes, and cabinets within a unified view, with integrated civil engineering data for accurate capacity planning and optimization.

Automated Fulfillment with Outage Management

Leverage a consistent CFS–RFS model to enable accurate service qualification, automated delivery, in-flight changes, and effective outage management across the network.

AI-Driven Planning & Validation Tools

Enhance network design with AI-assisted and rule-based planning tools, including cross-plan validation, final checks, and integrated project documentation (DMS) for faster and more accurate delivery.

Why Choose Web-Based Digital Twin for Modern Network Planning

Our Solution Advantages:

Legacy Limitation:

Tens of thousands of objects can be visualized with zero lag in a standard web browser using open-source GIS.
Specialized hardware, large installations, and slow rendering for dense maps are required by heavy desktop clients.
Deployment on modern, open-source databases such as PostGIS eliminates mandatory legacy license fees.
Heavy reliance on proprietary databases drives up total cost of ownership.
Historical GIS (Esri) data formats are handled securely while enabling the use of Google Maps, OpenStreetMap, or HERE.
Strict dependency on proprietary GIS vendors and geometric network models limits flexibility.
Physical inventory (OSP/ISP), logical inventory, and active services are seamlessly integrated to enable instant impact analysis.
PNI data is limited to physical street-level assets, restricting full network visibility.

FAQ: Network Engineering and Outside Plant Design

Our migration framework utilizes a specialized ETL (Extract, Transform, Load) engine designed to map complex legacy schemas directly to the TM Forum SID standard. We prioritize "Topological Integrity," ensuring that intricate parent-child relationships, ranging from underground duct systems down to individual fiber strands, are preserved without data loss. This ensures a seamless transition from rigid, on-premise inventory tools to a modern, Cloud-Native environment.

Yes. Comarch Communications Digital Twin is built on a microservices architecture, fully containerized using Docker and orchestrated via Kubernetes. It supports deployment across Public Clouds (AWS - Amazon Web Services, OCI - Oracle Cloud Infrastructure, GCP - Google Cloud Platform), Private Clouds, or Hybrid environments, allowing for elastic scaling during high-intensity network planning phases.

We follow a GIS-agnostic integration strategy. The platform can operate as a standalone geospatial engine or integrate seamlessly with Esri ArcGIS Pro/Online via RESTful APIs and Web Map Services (WMS/WFS). This allows for bi-directional synchronization: visualizing ArcGIS layers within the Digital Twin while exporting high-fidelity "As-Built" data back to the corporate GIS.

Absolutely. By leveraging the "As-Planned" layer of the Digital Twin, the system automatically extracts precise material lists and cost estimations. Our AI-driven planning modules optimize cable routing to minimize CAPEX while ensuring all engineering constraints and safety buffers are met.

The platform is natively aligned with the TM Forum Open Digital Architecture (ODA). We expose standard APIs, specifically TMF638 (Network Inventory) and TMF639 (Resource Inventory). This ensures "Future-Proof" interoperability with Southbound SDN controllers and Northbound Service Orchestration layers, eliminating vendor lock-in.

Moving to a Cloud-Native Digital Twin eliminates the high maintenance costs associated with on-premise legacy infrastructure and proprietary database licenses. Furthermore, establishing a 'Single Source of Truth' significantly reduces field visit errors by providing technicians with real-time data via mobile interfaces, effectively bridging the gap between the office and the field.

Absolutely. technicians can perform updates in the field using the OSS Mobile App even without a network connection. All entries are synchronized once connectivity is restored, maintaining a "Single Source of Truth" for your infrastructure. This seamless integration between office and field optimizes operational costs and ensures your digital twin remains 100% accurate.

Outside plant (OSP) refers to all physical network infrastructure outside buildings, such as fiber, ducts, manholes, and cabinets, that connects the network to end users. It requires precise planning, design, and lifecycle management, often supported by GIS tools and digital twin platforms. Comarch Communications supports OSP operations with a web-based network engineering platform that combines Physical Network Inventory (PNI) with a real-time digital twin, enabling accurate design, simulation, and end-to-end infrastructure management across the entire lifecycle.
