Page 5ETS 300 765-2: April 1998ForewordThis European Telecommunication Standard (ETS) has been produced by the Digital Enhanced CordlessTelecommunications (DECT) Project of the European Telecommunications Standards Institute (ETSI).Every ETS prepared by ETSI is a voluntary standard. This ETS may contain text concerning conformancetesting of the equipment to which it relates. This text should be considered as guidance only and does notmake this ETS mandatory.This ETS is based on ETS 300 175 parts 1 to 8 [1] - [8], EN 300 444 [13], ETS 300 822 [19],ETS 300 701 [21], ETS 300 651 [22] and ETS 300 755 [23]. This ETS has been developed in accordanceto the rules of documenting a profile specification as described in ISO/IEC 9646-6 [11].This ETS forms part 2 of a 2 part ETS, as follows:Part 1:"Basic telephony services";Part 2:"Advanced telephony services".Transposition datesDate of adoption of this ETS:20 March 1998Date of latest announcement of this ETS (doa):31 July 1998Date of latest publication of new National Standardor endorsement of this ETS (dop/e):31 January 1999Date of withdrawal of any conflicting National Standard (dow):31 January 1999SIST ETS 300 765-2:1999

Page 7ETS 300 765-2: April 19981ScopeThis European Telecommunication Standard (ETS) specifies that set of technical requirements for DigitalEnhanced Cordless Telecommunications (DECT) Fixed Part (FP) and DECT Cordless Terminal Adapter(CTA) for the support of the Radio in the Local Loop (RLL) Access Profile (RAP).The objective of this ETS is to ensure the air interface interoperability of DECT RAP CTAs and DECTRAP FPs and Wireless Relay Stations (WRSs) if applied.ETS 300 765-1 [16] contains the so called "Plain Old Telephone Service (POTS)" services includinganalogue leased lines and 64 kbit/s bearer service. ETS 300 765-1 [16] also provides for optional mobilityfeatures by supporting Generic Access Profile (GAP) Portable Part (PP) subscriber terminals and CTAswith WRS GAP functionality.This ETS contains telecommunication services as offered by Integrated Services Digital Network (ISDN),contemporary non-voiceband data services provided through, for example, a dedicated data port at theCTA, and support of digital leased lines. The provision of the mentioned services is not mandated by thisETS, but if provided they shall be provided as defined (provision optional, process mandatory).An objective is to use as much as possible from existing profiles: DECT/ISDN Intermediate ISDN accessProfile (IIP) as defined in ETS 300 822 [19] and the data profile A/B.2 as defined in ETS 300 701 [21],data profile C.2 as defined in ETS 300 651 [22], and data profile F.2 as defined in ETS 300 755 [23].Therefore, most of the RAP features refer to features defined in other profiles and the necessaryadditional features (e.g. Operation, Administration and Maintenance (OA&M)) are listed and explained inthis ETS.In addition, this ETS defines additional features, services, procedures, etc. for the CTA and the FT, whichare provision mandatory either in the CTA or in the FT, as well as some elements that are provisionoptional but still process mandatory. These features in particular define the operation and maintenance ofCTAs in relation to the provided service (profile) in a public network.2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.

Furthermore, features are added for theoperation, administration, and maintenance of the equipment (CTAs) offering the mentioned services inthe public RLL application.4.2.1ISDN servicesFor the definition of the ISDN services this ETS refers to ETS 300 822 [19], referred to as the IntermediateISDN access Profile (IIP).The IIP applies when FP and PP together constitute a gateway between an ISDN network and an ISDNterminal. The FP and the PP have an IWU, that maps the messages between the ISDN interface and theDECT air interface.The IIP specifies how ISDN services can be provided over DECT. It is based on DECT Common Interfacespecification ETS 300 175 [1] - [8] to enable ISDN terminals to have cordless access to an ISDNinfrastructure. Both public ISDN and private ISDN are within the scope of the IIP. For mobility and security,the IIP is based on EN 300 444 [13].Using the IIP, the end-user has transparent access to the ISDN services and functions. In respect tobearer services, the following are supported: speech, 3,1 kHz audio, unrestricted 64 kbit/s data, packetdata.SIST ETS 300 765-2:1999

Page 15ETS 300 765-2: April 1998In ETS 300 822 [19], reference configurations are used to describe the functional groupings of DECT andISDN and their relationships via reference points. In general, reference points may or may not correspondto a physical interface. The functional groupings and reference points are described in ITU-TRecommendation I.411 [20] for public ISDN.The DECT intermediate system reference configurations are used where the DIFS and DIPS togetherform an intermediate system to connect an ISDN-terminal to an ISDN network.The following figure shows the intermediate system reference configuration for public ISDN. Otherreference configurations are given in the IIP, ETS 300 822 [19], but are out of scope for this ETS, as theyapply to private ISDN.NT2TE1STDIPSDIDIFSIAVDIFS:DECT Intermediate Fixed SystemDIPS:DECT Intermediate Portable SystemIA:Interface AdapterFigure 2: Intermediate system public ISDN reference configuration4.2.2Non-voiceband data servicesThis ETS defines a number of advanced non-voiceband data services, based on the data services profilesas described in ETR 185 [24]. The data services profiles specify all the DECT air interface requirements toensure interoperability between DECT FPs and PPs, or CTAs in the RLL case. This clause defines howcertain data services which are particularly appropriate for RLL applications can be provided. However,the provision of these data services is optional.The data services defined in this clause are as follows:Table 1: Data services overviewData serviceConnection typeLocal network typeDECT profileLAN serviceConnection-lessNo Call signallingEthernet or Token Ringover LAN/FR/ATM(A/B.2), ETS 300 701 [21],clause A.2 or clause A.3Internet accessConnection-lessNo Call signallingInternet Protocol (IP)over LAN/FR/ATM(A/B.2), ETS 300 701 [21],clause A.4Internet access overPoint-to-Point Protocol(PPP)C/OCall signallingPPP overPSTN/ISDN/FR/ATMPPP Interworking,EN 301 240 [26]ModemC/OCall signallingPSTN/ISDN(C.2), ETS 300 651 [22],clause C.4Group 3 facsimileC/OCall signallingPSTN/ISDN(F.2), ETS 300 755 [23],annex CFor all DECT data profiles, the Mobility Class 2 shall apply as it contains CC and MM functionality requiredin the RLL application.Subclauses 4.2.2.1 to 4.2.2.4 define in detail the requirements for the provision of the data services aslisted in table 1. Annex C provides additional information of the realization of CTA data ports.4.2.2.1LAN serviceThe LAN service allows the transparent transport of ISO 8802-3 [29] (Ethernet) or ISO 8802-5 [29] (TokenRing) frames between a CTA data port, and a FP network data port. This service provides a general dataservice based on an ISO 8802 [29] MAC service.The LAN service is intended to provide connection of computer nodes connected to a local LAN to a nodein the network at MAC level. It allows a wide variety of current and future application tailored protocols ontop.SIST ETS 300 765-2:1999

Page 16ETS 300 765-2: April 1998To provide the LAN service, the CTA and FP shall provide the requirements listed in ETS 300 701 [21](service types A and B, Class 2). Furthermore, the CTA and FP shall use the inter-working proceduresdescribed in ETS 300 701 [21], clause A.2 or clause A.3, depending on the required LAN type.4.2.2.2Internet access4.2.2.2.1IP transport serviceThe IP transport service allows the transparent transport of IP datagrams between a CTA data port, and aFP network data port. The specifications in this subclause are intended to ensure full interoperabilitybetween CTAs (PPs) and FPs, regardless of the CTA or FP data port implementation. Options for CTAdata port implementation are given in annex C.The IP transport service is intended to provide permanent internet connection of standalone computernodes or LAN’s using IP protocol. It allows the transparent transport of any application protocol over IP.To provide internet access using the IP transport service, CTA and FP shall provide the requirementslisted in ETS 300 701 [21] (service types A and B, Class 2). CTA and FP shall use the interworkingprocedures described in ETS 300 701 [21], clause A.4.4.2.2.2.2Internet over Point-to-Point Protocol (PPP) serviceThe internet over PPP service allows the transport of IP datagrams encapsulated over PPP(see EN 301 240 [26]) between a CTA data port, and a FP data port. This service will also provide thetransport of PPP Link Control Protocol (LCP) and Network Control Protocols (NCPs) over the air interface,allowing the provision of PPP services as authentication, dynamic IP allocation, multilink aggregation, PPPdata compression, and any other service supported by PPP NCPs.This service is intended for non-permanent dial-up connections, or for any other type of connection thatmight require any service provided by the PPP. The internet over PPP service also provides call controlsignalling.To provide internet access using the internet over PPP service, CTA and FP shall provide therequirements and shall use the procedures described in EN 301 240 [26], ETS 300 651 [22], andETS 300 701 [21].The specifications in this subclause are intended to ensure full interoperability between CTAs (PPs) andFPs, and are only applicable to the DECT air interface, regardless of the CTA or FP implementation, andto the protocol stack presented in either, the CTA and FP data ports. The special cases of terminating thesubscriber side of the PPP link inside the CTA, or terminating the network side of the PPP link in the FPIWU are specifically considered. In these cases interfaces without PPP are presented to the subscriber ornetwork data ports.4.2.2.3ModemThis subclause specifies the normative aspects of the modem service as specified in this ETS. Thespecifications in this subclause are intended to ensure full interoperability between CTAs (PPs) and FPs,regardless of the CTA data port or FP IWU options given in annexes C and D.To provide modem service CTA and FP shall provide the requirements listed in ETS 300 651 [22]. CTAand FP shall use the interworking procedures described in ETS 300 651 [22], clause C.4.4.2.2.4Group 3 facsimileThis subclause specifies the normative aspects of the Group 3 (G3) facsimile service as specified in thisETS. The specifications in this subclause are intended to ensure full interoperability between CTAs (PPs)and FPs, regardless of the CTA data port or FP IWU options given in annexes C and D.To provide group 3 facsimile service CTA and FP shall provide the requirements listed inETS 300 755 [23]. CTA and FP shall use the interworking procedures described in ETS 300 755 [23],annex C.SIST ETS 300 765-2:1999
