SIST ETS 300 175-3:1999 is the Slovenian adoption of ETS 300 175-3 Edition 2 from ETSI. It specifies the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI) Medium Access Control (MAC) layer, including the services, logical channels, multiplexing, messages, primitives and procedures used between the MAC layer and the Physical Layer (PHL). It is aimed at people implementing, testing or buying DECT portable and fixed part equipment, including base stations, terminals and repeaters.
What does SIST ETS 300 175-3:1999 specify?
SIST ETS 300 175-3:1999 specifies Part 3 of the DECT Common Interface: the MAC layer, which is layer 2a of the DECT protocol stack. It covers three MAC service groups - broadcast message control, connectionless message control and multi-bearer control - and the logical channels and Service Access Points (SAPs) used to carry them.
The standard is organized into clauses 1 to 12 and annexes A, B, C, D, E, F, G, H and J. Clause 1 gives the scope, clause 4 describes the MAC layer, clause 5 lists the services, clause 6 explains multiplexing, clause 7 defines MAC messages, clause 8 defines primitives, and clauses 9 to 12 cover procedures, management and test behaviour.
| Annex | What it covers |

| A | MAC layer timers and constants |
| B | CRC polynomial construction and error-detecting performance |
| C | MAC relationship to other layers |
| D | Synchronisation |
| E | Scrambling patterns |
| F | Public Access Profile (PAP) mandatory MAC requirements |
| G | Public Access Profile (PAP) MAC requirements for optional features |

What are the key requirements of SIST ETS 300 175-3:1999?
Services, channels and SAPs
SIST ETS 300 175-3:1999 defines how the MAC layer serves the upper layers through MA SAP, MB SAP and MC SAP, plus ME SAP toward management and D SAP toward the PHL. In practice, this tells an implementer where each type of traffic belongs and how the MAC layer separates broadcast, connectionless and connection oriented traffic.
Clause 5 defines the logical channels used by those services: C, I and G for multi-bearer control, CL and SI for connectionless service, B for broadcast, and Q, N, M and P for internal MAC control. This matters because equipment has to place each kind of information on the correct channel family to support paging, system information, bearer setup and control signaling.
Bearers and connection types
Clause 5 also defines MAC bearers and MAC connections. A single-bearer connection uses one duplex bearer, while a multi-bearer connection combines one duplex bearer with additional duplex or double simplex bearers. In practice, this is the basis for capacity planning, bearer setup and handover design.
The standard distinguishes basic and advanced connections, symmetric and asymmetric connections, and connection identifiers. This matters because connection behavior changes with the connection type, especially when bandwidth changes, bearer replacement or handover are involved.
Multiplexing and field mapping
Clause 6 defines how data from different channels is combined into D-fields before delivery to the PHL. It uses bit mappings such as D-MAP, A-MAP and B-MAP, and time multiplexers such as T-MUX, C-MUX and E/U-MUX. For implementers, this is the part that turns logical MAC traffic into actual over-the-air frame content.
Clause 6.2 also covers scrambling, optional encryption and error control with R-CRC and X-CRC. That means a design has to generate the correct redundancy, apply the defined scrambling pattern and, where used, support encryption of the relevant channel data.
Message formats and control information
Clause 7 defines the message structures in the header, tail field and B-field. It includes system information, identities information, paging tails, MAC control messages, advanced connection control, quality control, test messages, extended system information and G-channel data packets. This matters because interoperability depends on correct message coding and correct use of the header bits.
The clause also states that reserved codes are for future use and that unimplemented messages shall be ignored. For a buyer or tester, this means equipment should not react unpredictably to unsupported or reserved message types.
Procedures for setup, handover, release and data transfer
Clauses 9 and 10 define the operational procedures. Clause 9 covers continuous and non-continuous broadcast, connectionless downlink and uplink, and paging procedures. Clause 10 covers connection setup, modification, release, bearer setup, bearer handover, bearer release and data transfer.
In practice, these clauses describe the exchange of bearer_request, bearer_confirm, WAIT, attributes_request, release and related messages. They are the core interoperability procedures for call setup, bandwidth changes and seamless movement between bearers.
Management and radio behaviour
Clause 11 defines management procedures such as broadcasting, extended system information, PP state transitions, physical channel selection, in-connection quality control, system load, and idle receiver scanning. This matters because DECT equipment has to find, select and monitor RF carriers in a coordinated way, and the standard gives the rules for that behaviour.
Annex A sets timers and constants such as connection setup, handover, paging and channel-selection timeouts. For a developer or test lab, these values define the timing limits against which implementations are checked.
Testing and public access profile support
Clause 12 defines the MAC layer test message procedure. It specifies how equipment in test standby mode shall react to test messages such as FORCE_TRANSMIT, LOOPBACK_DATA, DEFEAT_ANTENNA_DIVERSITY, FORCE_BEARER_HANDOVER, NETWORK_TEST, ESCAPE and CLEAR_TEST_MODES. This is important for type approval, conformance testing and manufacturing tests.
Annex F and Annex G define Public Access Profile (PAP) MAC requirements. Annex F covers mandatory PAP requirements, while Annex G covers optional features such as incoming call, alphanumeric messaging, encryption and bearer selection. These annexes matter when equipment is intended for PAP operation rather than only general DECT use.
What terms does SIST ETS 300 175-3:1999 define?
- Digital Enhanced Cordless Telecommunications (DECT) - the cordless telecommunications system family that this standard belongs to.
- Medium Access Control (MAC) - the layer that controls radio access, multiplexing, bearer handling and MAC signaling between the DLC layer and the PHL.
- Broadcast Message Control (BMC) - the MAC service group that carries broadcast information such as system and paging data.
- Connectionless Message Control (CMC) - the MAC service group that carries connectionless services without setting up a MAC connection.
- Multi-Bearer Control (MBC) - the MAC function that creates and manages MAC connections using one or more bearers.
- Portable Part (PP) - the portable DECT equipment side, including the portable radio termination.
- Radio Fixed Part (RFP) - the fixed radio side that transmits, receives and provides the radio interface for the cell.
- MAC Connection Endpoint Identifier (MCEI) - the identifier used to identify a MAC connection in connection oriented service primitives.
Who uses SIST ETS 300 175-3:1999?
SIST ETS 300 175-3:1999 is used by DECT equipment designers, radio protocol engineers, test laboratories, quality managers and certification teams. It is also relevant to buyers evaluating whether a DECT product supports the required MAC functions, such as paging, connection setup, handover, encryption control and test modes.
It is especially useful for teams working on PP, FT, FP, RFP and repeater implementations, because those roles have to agree on the same channel structure, timing, message formats and procedures.
What changed in SIST ETS 300 175-3:1999 from the previous edition?
SIST ETS 300 175-3:1999 is the second edition of ETS 300 175-3. The scope states that it updates ETS 300 175 based on experience from the development of TBR 6 and TBR 10 and on comments received.
Which standards are used with SIST ETS 300 175-3:1999?
SIST ETS 300 175-3:1999 refers to ETS 300 175-1 for the shared DECT definitions and abbreviations, and to ETS 300 175-2 for the Physical Layer and the D SAP. It also refers to ETS 300 175-4 for the Data Link Control (DLC) layer, ETS 300 175-6 for internal handover area concepts, and ETS 300 175-9 for the Public Access Profile (PAP).
The foreword also points to ETR 015, ETR 043 and ETR 056 for further DECT system details.
What does the SIST ETS 300 175-3:1999 document contain?
SIST ETS 300 175-3:1999 contains clause-level definitions of the MAC reference model, frame and multiframe structures, state definitions for PP and RFP, and the full set of MAC services. It gives the message fields and coding rules for the header, tail field and B-field, together with the control messages used for paging, system information, bearer setup, quality control, encryption control and test functions.
It also includes service primitives for connection oriented, connectionless, broadcast and management interactions, plus the procedures written as time-sequence descriptions for setup, modification, release, handover, broadcast and testing. The annexes add timers, constants, CRC background, synchronisation notes, scrambling patterns, PAP requirements and a bibliography.
