SIST EN 300 175-5 V2.9.1:2022
(Main)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).
The present document specifies the Network (NWK) layer. The NWK layer is part 5 of the ETSI 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 Recommendation ITU-T
X.200 [i.3] and Recommendation ITU-T 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. The present document also
includes super-wideband and fullband speech and audio services.

ETSI EN 300 175-5 V2.9.1 (2022-03) - Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 5: Network (NWK) layer
Overview
SIST EN 300 175-5 V2.9.1:2022 is a European standard that specifies the Network (NWK) layer of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). Developed by SIST in alignment with ETSI standards, this document defines the DECT NWK layer as the third layer in the DECT protocol stack. The scope is confined to the C-plane (control plane) of the NWK layer-responsible for internal signaling and network control-while user data handling (U-plane) is not addressed at this layer.
The NWK layer is crucial for supporting a broad range of DECT services by managing call control, supplementary services, message services, mobility, and linking functions. With the inclusion of New Generation DECT features, this standard paves the way for enhanced wideband, super-wideband, and fullband speech and audio capabilities, as well as improved data services and new technical enhancements.
Key Topics
- Network Layer Functions: Focuses on control, signaling, and networking for DECT systems, ensuring interoperability and reliable communication between devices.
- Protocols and Procedures: Defines families of protocols within the NWK layer, including:
- Call Control (CC): Manages call setup, maintenance, and release.
- Supplementary Services (SS): Supports advanced telephony features and keypad/feature key handling.
- Connection Oriented Message Service (COMS): Ensures reliable, connection-based messaging.
- ConnectionLess Message Service (CLMS): Delivers fixed and variable length messages without dedicated connections.
- Mobility Management (MM): Handles device identification, authentication, location updates, access rights, and security.
- Link Control Entity (LCE): Manages logical data links, paging, and message queuing.
- Layered Model Principles: Applies terminology and structure per ITU-T X.200 and X.210 recommendations, enhancing compatibility with international standards.
- Support for New Generation DECT: Integrates advanced speech codecs, new data slot types, and technical innovations for modern communication needs.
Applications
SIST EN 300 175-5 V2.9.1:2022 is foundational for:
- Telecommunications Equipment Manufacturers: Ensuring new DECT devices-such as cordless phones, base stations, enterprise systems-meet European and international market requirements.
- Network Operators: Providing guidelines for service implementation, network expansion, and compatibility, including seamless mobility and advanced telephony services.
- System Integrators: Facilitating the integration of DECT infrastructure into broader communication networks with control and signaling consistency.
- Testing and Certification: Offering a reference for conformance testing, quality assurance, and certification of DECT-compliant products.
Practical Benefits
- Interoperability: Promotes reliable operation among DECT devices from different vendors.
- Scalability: Supports enhanced services, including new audio codecs and data capabilities.
- Security: Enables robust mobility and authentication procedures, aligning with modern security demands.
- Flexibility: Facilitates advanced messaging and supplementary features, vital for both residential and enterprise use.
