Overview

SIST EN 300 175-5 V2.4.1:2012 is the harmonized European/SIST adoption of ETSI EN 300 175-5 (2012‑04). It defines the Network (NWK) layer of the DECT Common Interface (CI) and updates the NWK specification to support new functions introduced for NG‑DECT (Next Generation DECT), including enhanced security and new NG‑DECT mechanisms. The standard targets DECT systems operating in TDD/TDMA radio environments and addresses mobility, call control and message handling at the NWK layer.

Key topics and technical requirements

The standard provides functional definitions, procedures and message structures for NWK-layer services. Major technical topics include:

• Call Control (CC): call setup, service negotiation, connect, information, service change and release procedures (e.g., CC‑SETUP, CC‑CONNECT, CC‑RELEASE).
• Supplementary Services (SS): call‑related and independent services such as facility, hold/retrieve and feature key protocols.
• Connection Oriented Message Service (COMS): establishment, data transfer, suspend/resume and release (e.g., COMS‑SETUP, COMS‑INFO).
• Connectionless Message Service (CLMS): fixed and variable length message handling (e.g., CLMS‑VARIABLE).
• Mobility Management (MM): identity, authentication, location management, access rights, key allocation, parameter retrieval and ciphering procedures.
• Link Control Entity (LCE): data link endpoints, establishment, re‑establishment, release, suspend/resume and queuing.
• Message structures & information elements: S‑FORMAT messages and detailed functional contents for CC, SS, COMS, CLMS, MM and LCE messages.

The scope explicitly requires support for NG‑DECT mechanisms and security enhancements, so implementers must align NWK behaviours with updated authentication, key allocation and ciphering procedures.

Practical applications and users

This NWK‑layer standard applies to the design, implementation and testing of DECT/NG‑DECT systems and CI products. Typical users include:

• DECT handset and base station manufacturers implementing NWK protocol stacks.
• Chipset and firmware developers who integrate DECT CI features (call control, mobility, messaging).
• Network integrators and vendors deploying NG‑DECT systems for enterprise cordless telephony or specialized radio solutions.
• Test labs and certification bodies verifying conformance to ETSI/SIST requirements.
• Software developers building interoperability gateways (e.g., IWU interfaces) or mobility/management systems.

Keywords: DECT, NG‑DECT, SIST EN 300 175‑5, Network (NWK) layer, Common Interface CI, call control, mobility management, COMS, CLMS, security.

Related standards

• ETSI EN 300 175 series (Common Interface) - complementary parts define lower/upper layer interfaces and IWU/gateway aspects.
• NG‑DECT technical reports and adjacent ETSI DECT documents for radio and physical layer specifics.
