Page 7ETS 300 765-1: August 1997ForewordThis European Telecommunication Standard (ETS) has been produced by the Digital Enhanced CordlessTelecommunications (DECT) Project of the European Telecommunications Standards Institute (ETSI).Every standard prepared by ETSI is a voluntary standard. This ETS may contain text concerningconformance testing of the equipment to which it relates. This text should be considered as guidance onlyand does not make this ETS mandatory.This ETS is based on ETS 300 175, parts 1 to 8 [1] - [8] and ETS 300 444 [14]. This ETS has beendeveloped in accordance to the rules of documenting a profile specification as described inISO/IEC 9646-6 [11].This ETS consists of 2 parts as follows:Part 1:"Part 1: Basic telephony services";Part 2:"Advanced telephony services".Transposition datesDate of adoption:8 August 1997Date of latest announcement of this ETS (doa):30 November 1997Date of latest publication of new National Standardor endorsement of this ETS (dop/e):31 May 1998Date of withdrawal of any conflicting National Standard (dow):31 May 1998SIST ETS 300 765-1:1999

Page 9ETS 300 765-1: August 19971ScopeThis European Telecommunication Standard (ETS) specifies that set of technical requirements for DigitalEnhanced Cordless Telecommunications (DECT) Fixed Part (FP) and DECT Cordless Terminal Adapter(CTA) necessary for the support of the Radio in the Local Loop (RLL) Access Profile (RAP).The objective of the ETS is to ensure the air interface interoperability of DECT RAP CTAs and DECT RAPFPs and Wireless Relay Stations (WRSs) if applied.In addition, this ETS defines the features, services, procedures etc. for the CTA and the FT, which areprovision mandatory either in the CTA or in the FT, as well as some elements that are provision optionalbut still process mandatory.Another objective is to use as much as possible from the existing Generic Access Profile (GAP), but toexclude the not applicable GAP features. Therefore most of the RAP features refer to GAP features andthe necessary additional features (for example Operation, Administration, and Maintenance (OA&M)) arelisted and explained in this document.This ETS contains the so-called "Plain Old Telephone Service (POTS)" services including leased linesand 64 kbit/s bearer service.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.

PP is a generic term that may describe one or several physical pieces.NOTE 14:A DECT PP is logically divided into one PT plus one or more PAs.Portable radio Termination (PT): A logical group of functions that contains all of the DECT processesand procedures on the portable side of the DECT air interface.NOTE 15:A PT only includes elements that are defined in the DECT CI standard. This includesradio transmission elements (layer 1) together with a selection of layer 2 and layer 3elements.NOTE 16:A PT can also be the PT side of a WRS or the PT side of a CTA.Radio Fixed Part (RFP): One physical sub-group of a FP that contains all the radio end points (one ormore) that are connected to a single system of antennas.registration: An ambiguous term, that should always be qualified. See either location registration orsubscription registration.subscription registration: The infrequent process whereby a subscriber obtains access rights to one ormore FPs.NOTE 17:Subscription registration is usually required before a user can make or receive calls.Wireless Relay Station (WRS): A physical grouping that combines elements of both PTs and FTs torelay information on a physical channel from one DECT termination to a physical channel to anotherDECT termination.NOTE 18:The DECT termination can be a PT or an FT or another WRS.3.2AbbreviationsFor the purposes of this ETS, the following abbreviations apply:ACAuthentication CodeADPCMAdaptive Differential Pulse Code ModulationARIAccess Rights IdentityARQAutomatic Retransmission RequestCCCall ControlCICommon InterfaceCLIPCalling Line Identification PresentationCPECustomer Premises EquipmentCRFPCordless Radio Fixed PartCTACordless Terminal AdapterC/OConnection Oriented modeDCKDerived Cipher KeyDECTDigital Enhanced Cordless TelecommunicationsDLCData Link ControlDTMFDual Tone Multi-FrequencySIST ETS 300 765-1:1999

However, if aFT supports it there may be no corresponding action that the FT can take with the local network as aresult of this function.NOTE 3:This feature is required to be supported in the PT to guarantee the same level of security among allthe handsets that operates in a system. The invocation of the feature is however optional to theoperator.SIST ETS 300 765-1:1999
