SIST ETS 300 175-3 E1:2003 is the Slovenian version of ETS 300 175-3 Edition 1 from ETSI. It specifies the DECT Medium Access Control (MAC) layer for the Digital European Cordless Telecommunications Common Interface, including the services, logical channels, message formats, procedures and test behavior used by DECT fixed and portable parts.
What does SIST ETS 300 175-3 E1:2003 specify?
SIST ETS 300 175-3 E1:2003 specifies the MAC layer of the DECT Common Interface. In practice, this is the layer that sits between the DLC layer and the physical layer and defines how radio resources are organized, selected, controlled and tested.
The document is organized into clauses that cover the scope, references, definitions and abbreviations, MAC architecture, service overview, multiplexing, MAC messages, primitives, procedures, management procedures, and test message handling. It then adds Annex A for timers and constants, followed by informative annexes that explain CRC behavior, layer relationships, synchronisation, scrambling patterns, profile-related requirements and seamless handover.
| Annex | What it covers |
|---|---|
| Annex A | MAC layer timers and constants |
| Annex B | CRC polynomial construction and error detecting performance |
| Annex C | MAC relationship to other layers |
| Annex D | Synchronisation |
| Annex E | Scrambling patterns |
| Annex F | MAC layer services, procedures, scrambling, required messages and speech quality monitoring |
| Annex G | Public access profile requirements for optional features |
| Annex H | Seamless handover operation |
What are the key requirements of SIST ETS 300 175-3 E1:2003?
SIST ETS 300 175-3 E1:2003 defines how DECT MAC functions are split between broadcast, connectionless and multi-bearer control. It also defines how those functions are carried over logical channels, how bearers are built from radio transmissions, and how setup, release, handover and data transfer are sequenced.
MAC services and channel structure
Clause 5 groups the MAC services into BMC (Broadcast Message Control), CMC (Connectionless Message Control) and MBC (Multi-Bearer Control). This matters because each group uses different channels and procedures, so implementers need to support the right service set for the intended device role.
Clause 5.3 assigns the logical channels used by those services, including C, I, G, CL, SI, B, Q, N, M and P channels. Clause 5.4 then maps those services to the service access points MA SAP, MB SAP, MC SAP and ME SAP, which is the interface a stack or test system has to follow.
Bearers and connection types
Clause 5.5 and 5.6 describe MAC bearers and MAC connections. A single-bearer connection uses one duplex bearer, while a multi-bearer connection uses one duplex bearer plus one or more additional duplex or double simplex bearers.
That distinction matters in real products because bandwidth changes, asymmetric operation and handover all depend on which bearer arrangement is active. The standard also distinguishes basic and advanced connections, and symmetric and asymmetric connections, so the implementation has to keep track of the connection form it is actually supporting.
Broadcast and connectionless operation
Clause 5.7 defines how broadcast and connectionless services behave, especially in the downlink direction from FT to PT. It also sets rules for continuous service, including the use of dummy bearers or connectionless bearers and the conditions under which two bearers may be used.
This is important for paging and system information, because the fixed part must keep broadcasting reliably while still preserving other services. The clause also limits missed transmissions and gives the rules for how long extra bearers may remain active during certain transitions.
Multiplexing, scrambling, encryption and error control
Clause 6 explains how the MAC layer combines different logical-channel data into the physical transmission structure. It defines bit mappings, time multiplexers, encryption, scrambling and error control, so implementers know how the data fields are built before transmission.
The practical effect is that the stack has to apply the right combination of A-MAP, B-MAP, D-MAP, T-MUX, E/U-MUX and C-MUX rules. Clause 6.2.5 also introduces R-CRC and X-CRC, which are used to detect errors in the transmitted fields, and Annex B explains the CRC polynomial and detection properties.
Message formats and internal control information
Clause 7 defines the MAC message structure, including the header field, tail-field messages and B-field messages. It covers the N, Q, P and M tail messages, the main control and paging information they carry, and the B-field encodings used for connection control and quality control.
This clause is where an implementer learns how the actual on-air signalling is encoded. It also defines standard handling for binary coding, escape codes and reserved codes, which matters if a product supports proprietary extensions without breaking DECT-defined behavior.
Primitives to and from upper layers
Clause 8 describes the abstract MAC primitives exchanged with DLC, the management entity and the physical layer. It includes connection-oriented primitives such as MAC-CON, MAC-MOD, MAC-CO_DATA, MAC-DIS and MAC-BW, plus paging, connectionless and management primitives.
The clause is informational, but it is still useful because it shows the expected layer-to-layer behavior. For a developer, this is the bridge between protocol logic and implementation interfaces, especially for setup, release, bandwidth change and encryption control.
Procedures for setup, handover, release and data transfer
Clauses 9 and 10 define the operating procedures. Clause 9 covers broadcast and connectionless procedures, including downlink broadcast, downlink connectionless operation, paging broadcasts, uplink connectionless operation and the non-continuous broadcast procedure.
Clause 10 covers connection-oriented service procedures in detail: connection setup, modification, release, bearer setup, bearer handover, bearer release and data transfer. The text uses time-sequence style procedures, so in practice the implementer has to follow the exact order of transmissions, responses and waiting states.
Management, channel selection and test behavior
Clause 11 describes MAC management procedures such as broadcasting, extended system information, PP states and state transitions, physical channel selection, in-connection quality control, system load limits, PMID and FMID definitions, and receiver scan sequences. This is what makes real DECT devices interoperate in the field, because both PT and RFP have to scan and select channels in a compatible way.
Clause 12 defines the MAC test message procedure. It requires equipment that can transmit to recognize the standardized test messages, enter test standby mode, execute the static or dynamic test modes, and return to standby when clear test modes is received. This is the part used by conformance and approval test labs.
What terms does SIST ETS 300 175-3 E1:2003 define?
Antenna diversity is the ability of an RFP to choose between different antenna properties for each bearer, so the system can improve coverage and reception in practice.
Bearer handover is the MAC-layer internal handover where one MAC connection changes its underlying bearer while the DLC service continues.
Broadcast is simplex point-to-multipoint transmission, and the transmitter may ignore whether any receiver is present.
Connection handover is the DLC-layer internal handover where one set of DLC entities reroutes data from one MAC connection to another new MAC connection.
Cluster Control Function (CCF) is the logical control function that manages one cluster of cells and coordinates the MAC grouping for that cluster.
Portable part (PT) is the portable DECT unit that takes part in paging, bearer setup, scanning and handover behavior.
Fixed part (FT) is the fixed-side DECT equipment that transmits paging and broadcast information and participates in bearer setup and service control.
Who uses SIST ETS 300 175-3 E1:2003?
SIST ETS 300 175-3 E1:2003 is used by DECT radio equipment designers, protocol stack developers, test laboratories, certification bodies and quality or procurement teams working with DECT products. It is especially relevant when a project has to implement paging, bearer setup, handover, connectionless services, encryption control or MAC-layer test modes.
It is also useful to buyers and integrators who need to check whether a DECT product supports the MAC behavior expected by the rest of the DECT Common Interface stack.
