(Main)Digital Enhanced Cordless Telecommunications (DECT) - Generic Access Profile (GAP)
Digital Enhanced Cordless Telecommunications (DECT) - Generic Access Profile (GAP)
The present document specifies that set of technical requirements for Digital Enhanced Cordless Telecommunications
(DECT) Fixed Part (FP) and DECT Portable Part (PP) necessary for the support of the Generic Access Profile (GAP).
The GAP is applicable to all DECT Portable radio Terminations (PT) and Fixed radio Terminations (FT) which under
the scope of ETSI EN 300 176-2 [10] (i.e. 3,1 kHz telephony teleservice) and specifies the minimum functionality that
is supported by all other 3,1 kHz voice profiles.
The objective of the present document is to ensure the Air Interface (AI) inter-operability of DECT equipment capable
of 3,1 kHz telephony applications, in such a way that any DECT PT conforming to the procedures described in the
present document is inter-operable with any DECT FT conforming to the procedures described in the present document.
The profile consists of the minimum mandatory requirements that allow a 3,1 kHz teleservice connection to be
established, maintained and released between a FT and a PT with the appropriate access rights, irrespective of whether
the FP provides residential, business or public access services.
In addition, the present document defines the features, services, procedures etc. for both the FT and the PT, which are
provision mandatory either in the PT or in the FT, as well as some elements that are provision optional but still process
mandatory.
Mobility Management (MM) procedures at the DECT AI to support incoming calls and outgoing calls are included.
Inter-working between the FT and the attached network is outside the scope of the present document.
Digitalne izboljšane brezvrvične telekomunikacije (DECT) - Profil generičnega dostopa (GAP)
V tem dokumentu je določen nabor tehničnih zahtev za fiksni in prenosni del (FP in PP) za digitalne izboljšane brezvrvične telekomunikacije (DECT), ki podpirata profil generičnega dostopa (GAP).
GAP se uporablja za vse prenosne radijske postaje (PT) in fiksne radijske postaje (FT), ki jih zajema standard ETSI EN 300 176-2 [10] (npr. telefonska storitev prek frekvence 3,1 kHz), in določa minimalno funkcionalnost, ki jo podpirajo vsi drugi glasovni profili prek frekvence 3,1 kHz.
Namen trenutnega dokumenta je zagotoviti interoperabilnost radijskega vmesnika (AI) za opremo DECT, ki omogoča telefonske storitve prek frekvence 3,1 kHz, in sicer na način, pri katerem so vsi sistemi DECT PT, ki so skladni s postopki, opisanimi v tem dokumentu, interoperabilni z vsemi sistemi DECT FT, ki so skladni s postopki, opisanimi v tem dokumentu.
Profil vključuje minimalne obvezne zahteve za vzpostavitev povezave telefonskih storitev prek frekvence 3,1 kHz, pri čemer se takšne storitve vzpostavijo, vzdržujejo in sprostijo med FT in PT z ustreznimi pravicami za dostop, ne glede na to, ali FP zagotavlja stanovanjske, poslovne ali javne storitve dostopa.
Poleg tega so v tem dokumentu določene funkcije, storitve, postopki itd. za FT in PT, pri čemer so ti obvezni za PT ali FT, ter tudi nekatere elemente, ki so obvezni le za postopek.
Vključeni so tudi postopki upravljanja mobilnosti (MM) pri DECT AI, ki podpirajo dohodne in odhodne klice.
Medsebojno delovanje med FT-jem in priključenim omrežjem je zunaj obsega trenutnega dokumenta.
General Information
Overview
SIST EN 300 444 V2.5.1:2017 - also published as ETSI EN 300 444 V2.5.1 (2017-10) - defines the Digital Enhanced Cordless Telecommunications (DECT) Generic Access Profile (GAP). The standard specifies the minimum technical requirements for DECT Fixed Part (FP) and Portable Part (PP) equipment to ensure air‑interface interoperability for 3.1 kHz telephony teleservices. GAP guarantees that any DECT PT conforming to the document interoperates with any DECT FT conforming to it, regardless of residential, business or public access contexts. Inter‑working between the FT and external networks is explicitly outside the scope.
Key Topics and Requirements
- Interoperability focus: Minimum mandatory functionality to establish, maintain and release a 3.1 kHz teleservice connection between FT and PT.
- Device roles covered: Requirements and mandatory/optional provisions for both DECT Fixed Parts (FT) and Portable Parts (PT).
- Layered procedures: Definitions and requirements across protocol layers - NWK (network), DLC (data link control), MAC (medium access control), PHL (physical layer) - including service and feature mappings.
- Call procedures: Detailed Mobility Management (MM) and call control procedures for incoming and outgoing calls, including message flows and exceptional cases (release collisions, timers, rejections).
- Speech & audio: Speech coding and audio feature definitions relevant to 3.1 kHz telephony.
- Operational behavior: Handling of transactions, message formats, timers and error/exception conditions to ensure predictable cross‑vendor behavior.
- Keywords reflected in content: DECT, GAP, Generic Access Profile, ETSI EN 300 444, 3.1 kHz telephony, air interface interoperability, Fixed Part, Portable Part, mobility management, TDD, TDMA.
Practical Applications and Who Uses This Standard
- Device manufacturers: Implement DECT FT and PT products (cordless handsets, base stations, public DECT access points) that interoperate across vendors.
- Test and certification labs: Build conformance test suites and validate GAP compliance for product certification and Plugtests.
- System integrators & installers: Ensure DECT equipment will operate correctly in mixed vendor deployments for residential, enterprise or public access.
- Network planners/operators: Define deployment requirements where DECT provides voice services or interoperates with broader telephony systems (note: FT-to-network interworking is out of scope).
- Standards developers & researchers: Reference GAP when extending DECT profiles or aligning new voice profiles to the minimum 3.1 kHz teleservice baseline.
Related Standards
- ETSI EN 300 176-2 - referenced for the 3.1 kHz telephony teleservice scope.
- ETSI publications and national adoptions (SIST) that mirror ETSI EN 300 444.
This standard is essential for anyone developing, testing or deploying DECT devices and services who needs guaranteed air‑interface compatibility for classic telephony over DECT.

Frequently Asked Questions
SIST EN 300 444 V2.5.1:2017 is a standard published by the Slovenian Institute for Standardization (SIST). Its full title is "Digital Enhanced Cordless Telecommunications (DECT) - Generic Access Profile (GAP)". This standard covers: The present document specifies that set of technical requirements for Digital Enhanced Cordless Telecommunications (DECT) Fixed Part (FP) and DECT Portable Part (PP) necessary for the support of the Generic Access Profile (GAP). The GAP is applicable to all DECT Portable radio Terminations (PT) and Fixed radio Terminations (FT) which under the scope of ETSI EN 300 176-2 [10] (i.e. 3,1 kHz telephony teleservice) and specifies the minimum functionality that is supported by all other 3,1 kHz voice profiles. The objective of the present document is to ensure the Air Interface (AI) inter-operability of DECT equipment capable of 3,1 kHz telephony applications, in such a way that any DECT PT conforming to the procedures described in the present document is inter-operable with any DECT FT conforming to the procedures described in the present document. The profile consists of the minimum mandatory requirements that allow a 3,1 kHz teleservice connection to be established, maintained and released between a FT and a PT with the appropriate access rights, irrespective of whether the FP provides residential, business or public access services. In addition, the present document defines the features, services, procedures etc. for both the FT and the PT, which are provision mandatory either in the PT or in the FT, as well as some elements that are provision optional but still process mandatory. Mobility Management (MM) procedures at the DECT AI to support incoming calls and outgoing calls are included. Inter-working between the FT and the attached network is outside the scope of the present document.
