SIST EN 300 175-5 V2.2.1:2009
Digital Enhanced Cordless Telecommunications (DECT) - Common Interface (CI) - Part 5: Network (NWK) layer
General Information
- Abstract
The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). This part of the DECT CI specifies the Network (NWK) layer. The NWK layer is part 5 of the EN 300 175 and layer 3 of the DECT protocol stack. The present document only specifies the C-plane (control plane) of the DECT NWK layer. It contains no specification for the U-plane (user plane) because the U-plane is null for all services at the DECT NWK layer. The C-plane contains all of the internal signalling information, and the NWK layer protocols are grouped into the following families of procedures:
• Call Control (CC);
• Supplementary Services (SS);
• Connection Oriented Message Service (COMS);
• ConnectionLess Message Service (CLMS);
• Mobility Management (MM);
• Link Control Entity (LCE).
The present document uses the layered model principles and terminology as described in ITU-T Recommendations X.200 [i.3] and X.210 [i.4]. The present document includes New Generation DECT, a further development of the DECT standard introducing wideband speech, improved data services, new slot types and other technical enhancements.

ETSI EN 300 175-5 V2.2.1 (2008-11) - Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 5: Network (NWK) layer
Overview
SIST EN 300 175-5 V2.2.1:2009 is a standard developed by SIST based on the European Norm EN 300 175-5, which is part of the widely adopted Digital Enhanced Cordless Telecommunications (DECT) Common Interface specification. This part focuses on the Network (NWK) layer, which represents Layer 3 of the DECT protocol stack. The document precisely defines the structure and protocols for the NWK layer’s control plane (C-plane), responsible for managing internal signalling and control information in DECT systems.
The NWK layer is fundamental for establishing, maintaining, and releasing calls, providing crucial backbone procedures for mobility management, call control, and supplementary services in DECT-based wireless communications. The standard follows the layered model and terminology set by ITU-T Recommendations X.200 and X.210, ensuring compatibility and interoperability with broader telecommunication systems.
Key Topics
The SIST EN 300 175-5 V2.2.1:2009 standard covers several essential areas:
- Call Control (CC): Protocol procedures for setting up, maintaining, modifying, and releasing voice and data calls.
- Supplementary Services (SS): Mechanisms supporting features such as call hold, call forwarding, and feature key management.
- Connection Oriented Message Service (COMS): Reliable, connection-oriented message exchange.
- Connectionless Message Service (CLMS): Provides message exchange without establishing a dedicated connection.
- Mobility Management (MM): Procedures for authentication, user identity, location management, access rights, and ciphering to maintain secure and seamless mobility for DECT terminals.
- Link Control Entity (LCE): Manages the control and maintenance of data links, including establishment, suspension, resumption, and release.
- Signalling Message Formats: Specification of S-FORMAT and B-FORMAT message structures, elements, and related coding rules.
The scope explicitly excludes the user information transfer plane (U-plane), as it is null at the NWK layer in DECT systems.
Applications
This standard is essential for:
- DECT Equipment Manufacturers: It provides the definitive specification for implementing the control plane at the network layer, ensuring interoperability for cordless handsets, base stations, and infrastructure equipment.
- Telecommunications Operators: Guarantees network elements supporting mobility management, authentication, and supplementary services function reliably and according to best practices.
- Systems Integrators: Enables seamless integration of DECT wireless communication with other network protocols and services, including New Generation DECT offerings such as wideband speech and enhanced data services.
- Test and Certification Bodies: Offers the reference framework for conformance testing and certification, supporting robust, interoperable DECT deployments worldwide.
The standard supports the evolution of DECT in modern radio environments, including advanced slot types and improved data services for future-proof wireless solutions.
Related Standards
For comprehensive DECT implementation, the following related standards should be considered:
- EN 300 175-1: Overview and general description of the DECT Common Interface.
- EN 300 175-2: Physical (PHY) layer specification for DECT.
- EN 300 175-3: Medium Access Control (MAC) layer.
- EN 300 175-4: Data Link Control (DLC) layer.
- EN 300 175-6: DECT Common Interface - Connection Oriented and Connectionless Transport Layer.
- ITU-T X.200 and X.210: Foundational OSI reference model definitions.
- EN 300 175-7: Security features and supplementary services in DECT.
- EN 301 406: Harmonized standard for DECT requirements.
Adhering to this standard ensures devices and networks benefit from proven, standardized protocols for reliable, secure, and scalable DECT cordless communication.
