Title	Core Network and Interoperability Testing (INT); Network Digital Twin for Testing (NDT-T) Architecture, Models and Interfaces
Scope and Field of Application	This TS defines a standardized framework, data model, and interface architecture for a Network Digital Twin for Testing (NDT-T). The NDT-T provides a deterministic, reproducible, standards-based virtual representation of network functions and protocol behavior. It includes: NDT-T functional architecture; protocol behavior models (standardized); Managed Entity Service, Scenario Configuration, and Entity Output interface specifications; deterministic scenario execution models; mapping to existing ETSI test specifications (NDT, IMS, EPC/5GC, VoNR, NAS/NGAP, Interop test purposes, Plugtests suites); and ontology alignment rules (CIM, TC Data assets). The WI focuses strictly on standard network components, protocol-stack behavior, functional call flows, and testable interoperability elements as defined in ETSI INT and 3GPP specifications. Excludes vendor-specific, confidential management or proprietary algorithms.
