Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 3: Medium Access Control (MAC) layer
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 Medium Access Control (MAC) layer. The MAC layer is part 3 of the DECT
Common Interface standard and layer 2a of the DECT protocol stack.
It specifies three groups of MAC services:
• the broadcast message control service;
• the connectionless message control service; and
• the multi-bearer control service.
It also specifies the logical channels that are used by the above mentioned services, and how they are multiplexed and
mapped into the Service Data Units (SDUs) that are exchanged with the Physical Layer (PHL).
Figure 1.1: The DECT protocol stack
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.
Digitalne izboljšane brezvrvične telekomunikacije (DECT) - Skupni vmesnik (CI) - 3. del: Plast krmiljenja dostopa do prenosnega medija (MAC)
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.
General Information
Overview
SIST EN 300 175-3 V2.6.1:2015 defines the Medium Access Control (MAC) layer for the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). Part 3 of the DECT CI specification (layer 2a of the DECT protocol stack) describes MAC services, logical channels, and how MAC data is multiplexed and mapped into Service Data Units (SDUs) exchanged with the Physical Layer (PHL). The document also covers New Generation DECT enhancements such as wideband speech, improved data services and new slot types.
Key topics and technical requirements
- MAC service groups: specifies three primary service families:
- Broadcast Message Control (BMC)
- Connectionless Message Control (CMC)
- Multi-Bearer Control (MBC)
- Logical channels: definitions and roles of channels used by BMC, CMC and MBC; internal MAC control channels and SAP (Service Access Point) semantics.
- Multiplexing & mapping: rules for multiplexing logical channels and mapping into SDUs for interaction with the PHL, including bit mapping (MAP / D-MAP) strategies.
- Frame and multiframe structures: MAC-level framing and multiframe organization, including support for varied slot types introduced in New Generation DECT.
- Connection and bearer management: bearer types, connection-oriented services, symmetric/asymmetric and advanced connection behaviors, connection identifiers and complementary connections.
- State machines and control functions: definitions for PP/RFP states, Cluster Control Function (CCF) and Cell Site Functions (CSF) relevant to MAC operations.
- Broadcast & connectionless services: continuous/non-continuous broadcast, ULE broadcast support and connectionless uplink/downlink behavior.
- Inter-layer interfaces: clear SAP definitions (MA, MB, MC, ME) and order-of-transmission rules between MAC and higher layers.
Practical applications and who uses this standard
- Chipset and firmware developers implementing DECT MAC functionality for handsets, base stations, DECT repeaters and IoT endpoints.
- System integrators and product designers creating cordless telephony, wireless voice/data products and New Generation DECT devices (wideband voice, higher-rate data).
- Test labs and certification bodies validating compliance with DECT CI MAC requirements.
- Network planners and vendors designing multi-cell DECT deployments where MAC-layer multiplexing, paging and broadcast behaviors affect capacity and mobility.
- Standards engineers aligning higher-layer protocols to MAC services and logical channel semantics.
Related standards
- ETSI/EN DECT Common Interface series (other parts of EN 300 175 CI specification) and New Generation DECT documents defining physical layer and higher-layer protocols.

Frequently Asked Questions
SIST EN 300 175-3 V2.6.1:2015 is a standard published by the Slovenian Institute for Standardization (SIST). Its full title is "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 3: Medium Access Control (MAC) layer". This standard covers: 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 Medium Access Control (MAC) layer. The MAC layer is part 3 of the DECT Common Interface standard and layer 2a of the DECT protocol stack. It specifies three groups of MAC services: • the broadcast message control service; • the connectionless message control service; and • the multi-bearer control service. It also specifies the logical channels that are used by the above mentioned services, and how they are multiplexed and mapped into the Service Data Units (SDUs) that are exchanged with the Physical Layer (PHL). Figure 1.1: The DECT protocol stack 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.
