SIST EN 300 434-2 V1.2.1:2003 is a Slovenian standard identical to ETSI EN 300 434-2 V1.2.1. It specifies the access profile for DECT/ISDN interworking for end system configuration, setting the technical requirements for DECT Fixed Parts and Portable Parts that support the ISDN-DECT Access Service (IAS).
What does SIST EN 300 434-2 V1.2.1:2003 specify?
SIST EN 300 434-2 V1.2.1:2003 specifies the technical requirements needed to implement the ISDN-DECT Access Service on DECT equipment. It is written for DECT Fixed Parts (FPs) and Portable Parts (PPs) that claim interoperability for ISDN access.
The document is organized as follows:
- Clause 1: Scope
- Clause 2: References
- Clause 3: Definitions and abbreviations
- Clause 4: Features for the ISDN-DECT access service
- Clause 5: Requirements regarding the Network (NWK) layer
- Clause 6: Requirements regarding the DLC layer
- Clause 7: MAC layer requirements
- Clause 8: Requirements regarding the PHL layer
- Clause 9: Requirements regarding the speech transmission
- Annex A: Bibliography
Annex A is informative and lists background documents.
What are the key requirements of SIST EN 300 434-2 V1.2.1:2003?
Clause 4 defines the feature set for the access service and separates features into mandatory, optional, and conditional cases. In practice, this tells implementers which capabilities must be present for the minimum service and which ones only apply if the product supports them.
The minimum ISDN-DECT access service is built around a single call control instance, and the Network (NWK) layer does not require extended transaction identifiers. That matters because it limits the complexity of call handling and keeps the interworking profile narrower than the full DECT feature set.
Clause 5 maps features to procedures. The document states that when a feature is provided, its mapping to DECT procedures shall follow the listed rules. For example, outgoing call, incoming call, supplementary services, and data-related features each point to named procedures in EN 300 175-5 or EN 300 434-1, so an implementer can check the exact signaling behavior.
Clause 6 sets the Data Link Control (DLC) layer behavior. The control plane must support class A acknowledged transfer over connection-oriented and connectionless MAC service, with fragmentation using the CS logical channel and the more data bit. For incoming calls, both short and long broadcast frames are required, which matters for how paging and call setup are carried.
Clause 7 defines the Medium Access Control (MAC) layer requirements. If speech or voiceband data is used, the equipment must support basic connections and the U32a B-field multiplex type. If 64 kbit/s unrestricted digital information is used, it must support advanced connections and the U80a and E80 multiplex types. The clause also requires continuous broadcast service from the FT and defines the tail and B-field messages used for paging, link control, and advanced connection control.
Clause 8 sets the Physical Layer (PHL) rule: speech and voiceband data use full slots, while 64 kbit/s unrestricted digital information uses double slots. Clause 9 then points speech transmission for duplex speech back to EN 300 175-8. In practice, this means the air-interface timing and slot structure depend on the service being carried.
What terms does SIST EN 300 434-2 V1.2.1:2003 define?
- Fixed Part (DECT Fixed Part) (FP) - The physical grouping between the local network and the DECT air interface.
- Portable Part (DECT Portable Part) (PP) - The physical grouping between the user and the DECT air interface.
- Fixed radio Termination (FT) - The fixed-side radio functions defined in the DECT Common Interface.
- Portableradio Termination (PT) - The portable-side radio functions defined in the DECT Common Interface.
- ISDN Access Profile (IAP) - The defined part of the DECT/ISDN interworking standard that ensures interoperability for ISDN access services.
- Interworking Unit (IWU) - The unit used to interconnect sub-networks and provide the needed interworking functions.
- C-plane - The control plane of the DECT protocol stack.
- U-plane - The user plane of the DECT protocol stack.
Who uses SIST EN 300 434-2 V1.2.1:2003?
DECT equipment manufacturers use SIST EN 300 434-2 V1.2.1:2003 when designing FPs and PPs for ISDN access. Network and interworking engineers use it to align call control, paging, and data behavior with the specified profile.
Test laboratories and approval teams use it together with EN 300 176 and the referenced DECT common interface parts to verify interoperability and approval-related behavior. Buyers, integrators, and quality managers use it to check whether a product supports the access service features they need, such as speech, voiceband data, supplementary services, or 64 kbit/s data.
What changed in SIST EN 300 434-2 V1.2.1:2003 from the previous edition?
The history shows that this edition is V1.2.1, replacing V1.2.0. The scope notes that it implements pending changes requests.
Which standards are used with SIST EN 300 434-2 V1.2.1:2003?
- ETSI EN 300 175-2 - Defines the Physical Layer (PHL) used by the DECT air interface.
- ETSI EN 300 175-3 - Defines the Medium Access Control (MAC) layer, including paging and connection procedures.
- ETSI EN 300 175-4 - Defines the Data Link Control (DLC) layer.
- ETSI EN 300 175-5 - Defines the Network (NWK) layer and call control procedures.
- ETSI EN 300 175-8 - Defines speech coding and transmission.
- ITU-T Recommendation G.726 - Defines the ADPCM speech basis used for the speech service.
- ETSI EN 300 176 - Provides the approval test specification.
- ETSI EN 300 434-1 - Gives the interworking specification that this part profiles.
What does the SIST EN 300 434-2 V1.2.1:2003 document contain?
The document contains feature lists, procedure tables, layer-by-layer requirements, and message-handling rules. Table 1 links access-service features to mandatory, optional, or conditional support, while Table 2 links procedures to FT and PP status and to the base DECT clauses or companion standard parts.
It also gives the required tail codes, paging behavior, and MAC control messages, including special handling for incoming calls and 64 kbit/s data. For implementation work, that makes the document useful both for product design and for conformance or interoperability testing.
