ETSIEN 301 238 V1.1.3 (1998-06)81ScopeThe present document specifies a profile for Digital Enhanced Cordless Telecommunications (DECT) systemsconforming to EN 300 175, Parts 1 to 7 ([1] to [7]). It is part of a family of profiles aimed at the general connection ofterminals supporting non-voice services to a fixed infra-structure, private and public.The type D service, mobility class 2, as described in the ETR 185 [9] supports Isochronous Data Bearer Services(IDBSs) with mobility and is suitable for transparent transfer of isochronous data streams. It is intended for use inprivate and public roaming applications. Video telephony, video conferencing and secure telephone services (end-to-endencrypted) over external networks can be considered as applications of IDBS.Phase 1 of the present document defines an unprotected service offering an unrestricted digital 32 kbit/s data bearerservice, strongly based on the Generic Access Profile (GAP) (defined in EN 300 444 [8]), and an unprotected singlebearer, multi-rate, rate adaptation service to interwork to synchronous ITU-T Recommendations V.series interfaces isalso defined.Further phases of this profile may additionally provide multiple rate, multibearer support and limited error correctioncapability for services/applications requiring higher rates and high quality isochronous data transmission.The present document specifies the requirements on the Physical (PHL) layer, Medium Access Control (MAC) layer,Data Link Control (DLC) layer and Network (NWK) layer of DECT. The present document also specifies ManagementEntity (ME) requirements and generic Interworking Conventions (IC).2Normative referencesReferences may be made to:a)specific versions of publications (identified by date of publication, edition number, version number, etc.), inwhich case, subsequent revisions to the referenced document do not apply; orb)all versions up to and including the identified version (identified by "up to and including" before the versionidentity); orc)all versions subsequent to and including the identified version (identified by "onwards" following the versionidentity); ord)publications without mention of a specific version, in which case the latest version applies.A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]EN 300 175-1: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 1: Overview".[2]EN 300 175-2: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 2: Physical layer (PHL)".[3]EN 300 175-3: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 3: Medium Access Control (MAC) layer".[4]EN 300 175-4: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 4: Data Link Control (DLC) layer".[5]EN 300 175-5: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 5: Network (NWK) layer".[6]EN 300 175-6: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 6: Identities and addressing".SIST EN 301 238 V1.1.3:2003

The provisions of EN 300 175-6 [6] shall beimplemented with respect to the structure and use of identities.The Extended Higher Layer Fixed Part Information field shall be used with bit a44 set to 1, indicating the support of theD profile.Support for exchanged attribute procedures shall be mandatory (EN 300 175-5 [5], subclause 15.2.3).The <> element shall always be included in the {CC-RELEASE-COM} message.SIST EN 301 238 V1.1.3:2003

ETSIEN 301 238 V1.1.3 (1998-06)228.2RequirementsThe full requirements of the GAP, defined in EN 300 444 [8] clause 8 shall apply, with the following exceptions and/oradditions:a)both PP and FP shall set the info element <> (defined in EN 300 175-5 [5], subclause 7.6.4)to" Other" value;b)both PP and FP shall support the information element <> (defined in EN 300 175-5 [5],subclause 7.7.21);c)both PP and FP shall support the information element <> (defined in EN 300 175-5 [5],subclause 7.6.7).The specific coding required for the <> information element is defined in clause B.2 of thepresent document.9Management entity requirementsThe management entity shall be responsible for maintenance and updating of the logical associations between NWK,DLC, MAC and U-plane entities and shall contain the following procedure groups defined in EN 300 175-4 [4]:-MAC connection management;-DLC C-Plane management;-DLC U-Plane management.The requirements of mobility class 2 shall be met by the management procedures defined in EN 300 444 [8] with thefollowing exception:13.6Broadcast attributes managementRFPs belonging to the same LA shall broadcast the same values of higher layer attributes (see EN 300 175-5 [5],annex F) at any given time.The PP shall be capable to read and interpret at least the following broadcast attributes codings during lockingprocedure. In the locked state the PP may assume them as static.Table 102: Fixed Part Capabilities Broadcast attributes interpretation by the PP (see EN 300 175-5 [5],clause F.1)Bit numberAttributeValueNotea34Non-voice circuit switched serviceAlla36Standard authentication requiredAlla37Standard ciphering supportedAlla38Location registration supportedAlla44Access rights requests supportedAlla46Connection handover supportedAllTable 102a: Extended Fixed Part Capabilities Broadcast attributes interpretation by the PP(see EN 300 175-5 [5], clause F.2)Bit numberAttributeValueNotea44Data service profile DAllSIST EN 301 238 V1.1.3:2003

ETSIEN 301 238 V1.1.3 (1998-06)2310Generic interworking conventions and procedures10.1Bit orderingIn order to interwork with other different networks, the data stream in the U-plane shall respect the bit ordering ruledescribed in EN 300 175-3 [3], subclause 5.4.5. For simplicity, the same subclause is reproduced below.5.4.5Order of transmissionCertain primitives exchanged between the MAC layer and the DLC layer may have a SDU containing peer-to-peermessages. The Service Data Unit (SDU) data is arranged as a list of octets or part octets, starting with octet 1. The bitswithin one octet are numbered from 1 to 8 where the most significant bit has number 8. The MAC layer transmits theseoctets in ascending order, starting with octet 1. Valid bits within one octet are transmitted in descending order.The same bit ordering shall be maintained at the interface between the DECT DLC U-plane and the InterWorking Unit(IWU) in the FP. The same bit ordering shall be maintained at the interface between the DECT DLC U-plane and theTerminal Adaptation Functions (TAF) in the PP.SIST EN 301 238 V1.1.3:2003

ETSIEN 301 238 V1.1.3 (1998-06)24Annex A (normative):LU9 - Unprotected Rate Adaptation for V.series Equipment(RAVE) serviceA.1OverviewThe LU9 service provides for the transparent transport of synchronous continuous data at rates suitable for data terminalequipment with V.series interfaces. Specific support for low speed Asynchronous Transfer Mode (ATM) AdaptationLayer - 1 (AAL-1) rates is also provided.The unprotected service offers no error correction of user data and no notification of errors. It therefore offers a sim
