Ta dokument je eden od delov specifikacije skupnega vmesnika (CI) za digitalne izboljšane brezvrvične telekomunikacije (DECT).
Ta dokument določa plast krmiljenja dostopa do prenosnega medija (MAC). Plast krmiljenja dostopa do prenosnega medija je 3. del standarda za skupni vmesnik za digitalne izboljšane brezvrvične telekomunikacije, plast 2a pa sklada protokolov digitalnih izboljšanih brezvrvičnih telekomunikacij.
Določa tri skupine storitev krmiljenja dostopa do prenosnega medija:
• storitev nadzora sporočil za oddajanje;
• storitev nadzora sporočil brez povezave; in
• storitev nadzora več nosilcev.
Poleg tega določa logične kanale, ki jih uporabljajo zgornje storitve, ter kako so ti kanali multipleksirani in preslikani v podatkovne enote storitve (SDU-je), ki se izmenjavajo s fizično plastjo (PHL).
Ta dokument vključuje novo generacijo digitalnih izboljšanih brezvrvičnih telekomunikacij, nadaljnji razvoj standarda za digitalne izboljšane brezvrvične telekomunikacije, ki uvaja širokopasovni govor, izpopolnjene podatkovne storitve, nove tipe rež in druge tehnične izpopolnitve.

ETSI EN 300 175-3 V2.6.1 (2015-07) - Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 3: Medium Access Control (MAC) layer
Overview
SIST EN 300 175-3 V2.6.1:2015 is an international standard focusing on Digital Enhanced Cordless Telecommunications (DECT), specifically the Common Interface (CI) Part 3, which defines the Medium Access Control (MAC) layer. Issued by SIST, this standard forms a crucial component in the DECT protocol stack, facilitating reliable wireless communication for cordless telecommunications systems. The MAC layer (Layer 2a) is central to managing communication services, supporting enhancements brought by New Generation DECT, such as wideband speech and improved data capabilities.
Key Topics
This standard details the functional aspects of the DECT MAC layer, addressing:
Three groups of MAC services:
- Broadcast Message Control (BMC) Service: Manages system information broadcast to multiple receivers.
- Connectionless Message Control (CMC) Service: Supports exchange of messages without establishing persistent connections.
- Multi-Bearer Control (MBC) Service: Handles multiple simultaneous data streams or communication ‘bearers’.
Logical Channels: Specifies how various services use logical channels and their mapping into Service Data Units (SDUs) for transfer between the MAC and Physical Layer (PHL).
Multiplexing and Mapping: Defines mechanisms for combining and separating data streams through multiplexing, optimizing the use of communication slots and bandwidth.
Frame and Multiframe Structures: Describes how time is organized in frames and multiframes, enabling efficient and synchronized wireless communication.
New Generation DECT Enhancements: Incorporates technical improvements for modern DECT applications, like wideband audio and new slot types.
Applications
This standard is essential for manufacturers, developers, and integrators involved in:
- Cordless Telephony Systems: Ensures interoperability between base stations and handsets from different vendors.
- Wireless Data Communication: Supports robust voice and data transmission in residential, enterprise, and industrial environments.
- DECT-based IoT Solutions: Facilitates scalable machine-to-machine communication, suitable for smart home and automation projects.
- Telecommunication Equipment Certification: Provides a technical foundation for compliance testing and quality assurance in the DECT product ecosystem.
By implementing the specifications for the MAC layer, stakeholders can achieve consistent medium access, reliable connection management, and high system capacity-crucial for the deployment and operation of DECT solutions.
Related Standards
Organizations developing DECT systems or ensuring compliance should also refer to related international standards, including:
- SIST EN 300 175-1: Overview and general requirements for the DECT Common Interface.
- SIST EN 300 175-2: Physical layer (PHL) specifications.
- SIST EN 300 175-4: Data Link Control (DLC) layer, the next layer up in the protocol stack.
- SIST EN 301 406: Harmonized EN for DECT equipment in terms of essential requirements under the EU Radio Equipment Directive.
Practical Value
By following SIST EN 300 175-3 V2.6.1:2015, developers ensure that their DECT implementations provide robust, interoperable, and efficient communication. The standard supports the evolution of DECT technologies, addressing both legacy and next-generation requirements for wireless voice and data applications.
