SIST EN 300 444 V2.1.1:2009

• Abstract:

  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 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.

SIST EN 300 444 V2.1.1:2009 is the Slovenian adoption of ETSI EN 300 444 for Digital Enhanced Cordless Telecommunications (DECT) - Generic Access Profile (GAP). It specifies the minimum technical requirements for DECT Fixed Part (FP) and DECT Portable Part (PP) needed to support 3,1 kHz telephony and to make DECT equipment inter-operable over the Air Interface (AI).

What does SIST EN 300 444 V2.1.1:2009 specify?

SIST EN 300 444 V2.1.1:2009 specifies the GAP requirements that DECT PT and FT equipment need in order to establish, maintain and release a 3,1 kHz teleservice connection with the right access rights. The profile is the common baseline for DECT voice use cases, including residential, business and public access services.

The document applies to DECT Portable radio Terminations (PT) and Fixed radio Terminations (FT) that fall under EN 300 176-2 for 3,1 kHz telephony teleservice. Inter-working between the FT and the attached network is outside its scope.

The document is organized into clauses on:

• references and definitions
• feature and service definitions
• interoperability requirements
• procedure descriptions
• NWK, DLC, MAC and PHL procedures
• speech transmission requirements
• management procedures
• application procedures

What are the key requirements of SIST EN 300 444 V2.1.1:2009?

SIST EN 300 444 V2.1.1:2009 is mainly a profile specification, so its core job is to tell implementers which DECT features, services and procedures must work together. In practice, a product is GAP-compliant only if it follows the mandatory behavior for the role it plays, whether that is PT, FT, or both.

Interoperability profile and support classes

Clause 6 maps NWK features, DLC services, MAC services, application features, and speech coding/audio features to PT and FT support. The tables use support codes such as M, O, C and N/A to show what is mandatory, optional, conditional, or not applicable for each side.

This matters because buyers and test teams can see quickly which functions are part of the common profile and which are only available in specific product combinations. For example, the baseline includes outgoing and incoming call handling, off-hook, on-hook, dialled digits, alerting, subscription registration on-air and link control.

Clause 6 also includes advanced functions such as authentication of the PP and FT, location registration, encryption activation and deactivation, CLIP, CNIP, internal call, service call, handover and extended frequency allocation. These features are useful when a system must support roaming, security, internal calling or caller identity presentation.

Call control and mobility procedures

Clause 7 states that the listed protocol elements are process mandatory. That means the relevant entity must send, receive and process the elements required by its role, and the normal case, associated procedures and exceptional cases are all part of the procedure.

Clause 8 defines NWK-layer procedures for outgoing call setup, overlap sending, call proceeding, call confirmation, connection, normal and abnormal release, partial release, keypad information, display, terminal capability indication, internal call setup, service call setup, identification of PP, authentication, access rights, key allocation, cipher switching, link establishment and link release.

This is the section to use when checking actual call behavior. It shows how a GAP handset and base station should react to timers, release collisions, rejects and timeouts so that a call does not fail in an ambiguous way.

A few practical examples stand out:

• For outgoing calls, keypad information is carried in the defined CC-INFO paths.
• For call proceeding, if the Progress indicator shows in-band information or an appropriate pattern is now available, the PT is expected to connect the U-plane.
• For incoming calls, the FT may include calling party information, alerting and ringing behavior.
• For display handling, the PT and FT display information must stay logically separate so the two sources are not mixed on the same display.

Link, bearer and radio-layer behavior

Clause 9 covers DLC-layer procedures such as Class A link establishment, acknowledged information transfer, C channel fragmentation and recombination, basic connection handover, encryption switching and U-plane class 0/minimum delay. This is the lower-layer control that keeps the link usable during normal operation and handover.

Clause 10 covers MAC-layer procedures such as broadcast, paging, basic connection setup, bearer and connection handover, C-channel data, encryption initialization and synchronization, encryption mode control and extended frequency allocation. Clause 11 then adds PHL requirements, including Minimum Normal Transmit Power (NTP), radio receiver sensitivity, sliding collision detection, physical channel availability and synchronization window.

In practice, these clauses are what engineers use to check that a device can actually get on the air, stay connected and recover properly when radio conditions change.

Security, identities and subscription data

Clause 8 includes authentication of FT and PP, location registration, obtaining access rights, FT terminating access rights, key allocation, cipher-switching and storing the DCK. The document uses identities such as IPUI, PARK, TPUI, PARI and RPN to identify the portable side and the fixed side.

Clause 13 covers management of MM procedures, assigned individual TPUI management, PMID management, DCK management, broadcast attributes management and storage of subscription-related data. This is important for products that must remember subscription data across power cycles and network changes.

Clause 6.9.4 adds a practical error-handling rule: a reserved value in an information element is not an error by itself. If the receiver understands it, it processes the value; otherwise it ignores it.

What terms does SIST EN 300 444 V2.1.1:2009 define?

• Fixed Part (FP) - the DECT infrastructure side that provides coverage and services to portable equipment.
• Fixed radio Termination (FT) - the logical group of functions on the fixed side of the DECT Air Interface.
• Portable Part (PP) - the user-side DECT equipment, which may be one or several physical pieces.
• Portable radio Termination (PT) - the logical group of DECT functions on the portable side of the Air Interface.
• Mobility Management (MM) - the DECT procedures that support call handling, location registration, access rights and related mobility functions.
• Location Area (LA) - the area in which a PP can make or receive calls after a single location registration.
• Calling Line Identification Presentation (CLIP) - the function that provides the calling party number before the called party accepts the call.
• Calling Name Identification Presentation (CNIP) - the function that provides the calling party name before call acceptance.

Who uses SIST EN 300 444 V2.1.1:2009?

SIST EN 300 444 V2.1.1:2009 is used by DECT equipment manufacturers, system integrators, test laboratories, quality managers and buyers who need a common voice profile for interoperability. It is relevant wherever 3,1 kHz telephony services are implemented over DECT.

It is especially useful for teams working on:

• DECT handsets, base stations and accessories
• residential, business and public access services
• roaming between coverage areas
• caller identity features such as CLIP and CNIP
• security functions such as authentication and ciphering
• conformance or interoperability testing against the GAP profile
