SIST ETS 300 444 E1:2003 is the Slovenian adoption of ETS 300 444 Edition 1, published by SIST. It specifies the DECT Generic Access Profile (GAP), the minimum technical functions and procedures needed for 3,1 kHz telephony access with mobility and air-interface interoperability between a Digital Enhanced Cordless Telecommunications (DECT) Fixed Part (FP) and Portable Part (PP). It is aimed at equipment that supports speech and the access rights needed to connect, maintain, and release calls.

What does SIST ETS 300 444 E1:2003 specify?

SIST ETS 300 444 E1:2003 specifies the GAP for DECT equipment. The profile defines the minimum mandatory behavior needed for a PP and an FT to establish, maintain, and release 3,1 kHz telephony connections, while supporting mobility and interoperability across fixed networks.

The document is organized as a profile specification. It starts with scope and normative references, then gives definitions, feature and service definitions, interoperability requirements, NWK, DLC, MAC and PHL procedures, speech transmission requirements, management procedures, and application procedures. Informative annexes cover subscription locking, tones and progress indication, and changes relative to ETS 300 175.

Annex	What it covers
Annex A	PP locking procedure for on-air subscription
Annex B	Tones, progress indicator and U-plane connection
Annex C	ETS 300 175 changes

What are the key requirements of SIST ETS 300 444 E1:2003?

The GAP in SIST ETS 300 444 E1:2003 is built around interoperability. Clause 6 and the related tables define which features and services are mandatory, conditional, optional, or not applicable for the PT and FT roles. In practice, this is the first place to check whether a product must support a feature at all, and in which role.

Feature and service coverage

Clause 6 maps NWK features, DLC services, MAC services, and application features to implementation status. The tables cover call-related functions such as outgoing call, incoming call, alerting, release, DTMF, display, registration, authentication, ciphering, link control, and internal or service calls. For a buyer or engineer, the table tells you whether a handset, base station, or both must implement a function.

Procedure structure and error handling

Clause 7 says the procedures are process mandatory and are described in normal cases, associated procedures, and exceptional cases. That means a device that supports a procedure must also support the timer handling and error paths attached to it. The clause also states that the abstract primitives are for describing interactions, not for formal testing.

Call control and user-facing behavior

Clause 8 defines the NWK procedures for outgoing and incoming call handling, call confirmation, call connection, call release, partial release, keypad information, display, and terminal capability indication. It also covers internal call set-up and service call set-up. In practice, these clauses describe the voice-call behavior a compatible PT and FT must show on the air interface.

Mobility, identification, and access rights

Clause 8 also defines identification of PP, location registration, location update, obtaining access rights, and FT terminating access rights. These procedures are what let the network know where the PP is reachable and whether it is allowed to use the service. For implementation, this is the core of roaming and access-control behavior.

Security and subscription functions

Clause 8 includes authentication of FT, authentication of PP, authentication of user, key allocation, storing the DCK, incrementing the ZAP value, and cipher-switching initiated by FT or PT. It also defines the use of access-rights and subscription-related data. In practice, these procedures control who may use the system and when ciphering is enabled or disabled.

Link, data link, and radio control

Clauses 8 to 10 cover indirect and direct link establishment, normal, abnormal and maintain link release, Class A DLC procedures, MAC layer broadcast and paging, basic connections, handover, encryption mode control, and extended frequency allocation. These are the lower-layer mechanisms that carry the call-control and speech traffic over the DECT air interface.

Radio and speech requirements

Clause 11 sets PHL requirements such as Minimum Normal Transmit Power (NTP), radio receiver sensitivity, Z-field, sliding collision detection, physical channel availability, and synchronisation window. Clause 12 adds speech transmission requirements, including user controlled volume control. For product design and test, these are the radio-performance and audio-usability items that must be checked.

Management and application procedures

Clause 13 covers management of MM procedures, location registration initiation, Assigned individual TPUI management, PMID management, DCK management, broadcast attributes management, and storage of subscription related data. Clause 14 covers subscription control, AC to bitstring mapping, and manual entry of the PARK. These clauses matter for provisioning, factory setup, and user subscription workflows.

What terms does SIST ETS 300 444 E1:2003 define?

• Fixed Part (FP) - the physical grouping between the local network and the DECT air interface, containing at least one Fixed radio Termination and any extra implementation-specific elements.
• Fixed radio Termination (FT) - the logical set of DECT processes and procedures on the fixed side of the air interface.
• Portable Part (PP) - the portable DECT equipment that operates within the coverage of a Fixed Part and uses the defined access rights.
• Location Area (LA) - the domain in which a PP may receive or make calls after a single location registration.
• C-plane - the control plane of the DECT protocol stack, containing the internal protocol control up to and including the NWK layer.
• location registration - the process that determines the PP position to the level of one Location Area and updates that position in one or more databases.
• authentication - the process that positively verifies a DECT subscriber as a legitimate user of a particular FP.
• handover - the switching of a call in progress from one physical channel to another physical channel.

Who uses SIST ETS 300 444 E1:2003?

SIST ETS 300 444 E1:2003 is used by DECT equipment manufacturers, handset and base-station designers, chipset and firmware teams, and test laboratories. It is also used by quality managers, certification teams, and technical buyers who need to confirm that a product supports GAP-compatible speech services.

In practice, it supports:

• product design for DECT FP and PP equipment
• interoperability testing between different vendors’ equipment
• conformance and approval work for 3,1 kHz telephony applications
• subscription, security, and roaming behavior checks
• implementation reviews for call control, handover, and radio-layer behavior

What does the SIST ETS 300 444 E1:2003 document contain?

The document contains feature tables, service tables, and procedure descriptions for the PT and FT roles. It also contains timer management, message contents, information-element coding, and exception handling for call control, registration, security, link control, MAC behavior, and DLC behavior.

It includes detailed tables for terminal capability coding, display support, and storage of identities and subscription data. Annex A gives a PP locking procedure for on-air subscription, Annex B covers tones and progress indicators with U-plane connection, and Annex C summarizes changes to ETS 300 175. The document also uses figures and tables to show call flows, message values, and display scrolling behavior for implementation and testing.

1 Scope
This ETS specifies that set of technical requirements for Digital European 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 are subject to CTR 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 ETS 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 this ETS is inter-operable with any DECT FT conforming to the procedures described in this ETS.
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, this ETS 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 this ETS.

3 Definitions, abbreviations and symbols
3.1 DECT definitions
For the purposes of this ETS the following definitions apply.
attach: The process whereby a PP within the coverage area of a FP to which it has access rights, notifies
this FP that it is operative. The reverse process is detach, which reports the PP as inoperative.
NOTE 1: An operative PP is assumed to be ready to receive calls.
authentication: The process whereby a DECT subscriber is positively verified to be a legitimate user of a
particular FP.
NOTE 2: Authentication is generally performed at call set-up, but may also be done at any other
time (e.g. during a call).
bearer service: A type of telecommunication service that provides a defi
