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.

The logical boundaries of the DECT network are defined to be at the top of theDECT network layer.NOTE 6:A DECT Network is a logical grouping that contains one or more fixed radioterminations plus their associated portable radio termination. The boundaries of theDECT network are not physical boundaries.DECT intermediate fixed system: A logical grouping that contains all the functions between the DECT DIreference point and the reference point on the fixed side of the DECT air interface.NOTE 7:The DECT Intermediate Fixed System (DIFS) = FT + (local network up to the fixedside ISDN reference point (including fixed side Interworking Unit (IWU))), seeETR 056 [14].DECT intermediate portable system: A logical grouping that contains all the functions between theDECT DI reference point and the ISDN S reference point on the portable side of the DECT air interface.SIST ETS 300 765-2:1999



Page 10ETS 300 765-2: April 1998NOTE 8:The DECT Intermediate Portable System (DIPS) = Portable radio Termination (PT) +(Portable Application (PA) up to the portable side ISDN S reference point (includingportable side IWU)), see ETR 056 [14].Fixed Radio Termination (FT): A logical group of functions that contains all of the DECT processes andprocedures on the fixed side of the DECT air interface.NOTE 9:A FT only includes elements that are defined in the DECT Common Interface (CI)standard. This includes radio transmission elements together with a selection of layer2 and layer 3 elements.handover: The process of switching a call in progress from one physical channel to another physicalchannel.NOTE 10:There are two physical forms of handover, intra-cell handover and inter-cell handover.incoming call: A call received at a CTA.inter-cell handover: The switching of a call in progress from one cell to another cell.internal handover: Handover processes that are completely internal to one FT. Internal handoverreconnects the call at the lower layers, while maintaining the call at the NWK layer.NOTE 11:The lower layer reconnection can either be at the Data Link Control (DLC) layer(connection handover) or at the MAC layer (bearer handover).interoperability: The capability of FPs and CTAs, that enable a CTA to obtain access to teleservices inmore than one location area and/or from more than one operator (more than one service provider).Interworking Unit (IWU): A unit that is used to interconnect subnetworks.NOTE 12:The IWU will contain the interworking functions necessary to support the requiredsubnetwork interworking.intra-cell handover: The switching of a call in progress from one physical channel of one cell to anotherphysical channel of the same cell.Local Network (LNW): A telecommunication network capable of offering local telecommunicationservices.NOTE 13:The term does not include legal or regulatory aspects, nor does it indicate if thenetwork is a public network or a private network.location area: The domain in which a CTA may receive (and/or make) calls as a result of a singlelocation registration.location registration: The process whereby the position of a DECT PT is determined to the level of onelocation area, and this position is updated in one or more databases.NOTE 14:These databases are not included within a DECT FT.MAC Connection (CONNECTION): An association between one source MAC Multi-Bearer Control(MBC) entity and one destination MAC MBC entity. This provides a set of related MAC services (a set oflogical channels), and it can involve one or more underlying MAC bearers.mobility class 1: Local area applications, for which terminals are pre-registered off-air with one or morespecific fixed parts, and establishment of service and user parameters is therefore implicit, according to aprofile-defined list.mobility class 2: Private and Public roaming applications for which terminals may move between fixedparts within a given domain and for which association of service parameters is explicit at the time ofservice request.SIST ETS 300 765-2:1999



Page 11ETS 300 765-2: April 1998outgoing call: A call originating from a CTA.Portable Application (PA): A logical grouping that contains all the elements that lie beyond the DECTnetwork boundary on the portable side.NOTE 15:The functions contained in the PA may be physically distributed, but any suchdistribution is invisible to the DECT network.Portable Part (DECT Portable Part) (PP): A physical grouping that contains all elements between theuser and the DECT air interface. PP is a generic term that may describe one or several physical pieces.NOTE 16: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 17: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.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.service type A: Low speed frame relay, with a net sustainable throughput of up to 24 kbits/s, optimizedfor bursty data, low power consumption and low complexity applications such as hand-portableequipment.service type B: High performance frame relay, with a net sustainable throughput of up to 552 kbits/s,optimized for high speed and low latency with bursty data. Equipment implementation the Type B profileshall inter-operate with Type A equipment.service type C: Non-transparent connection of data streams requiring Link Access Protocol (LAP)services, optimized for high reliability and low additional complexity. This builds upon the services offeredby the type A or B profiles.service type E: A short message transfer or paging service which may be unacknowledged oracknowledged, optimized for small Service Data Units (SDUs), low PP complexity and ultra-low powerconsumption.service type F: An application profile specifically supporting teleservices such as fax, building upon theservices offered by the type A/B and C profiles, optimized for terminal simplicity, spectrum efficiency andnetwork flexibility.subscription registration: The infrequent process whereby a subscriber obtains access rights to one ormore FPs.NOTE 18:Subscription registration is usually required before a user can make or receive calls.SIST ETS 300 765-2:1999



Page 12ETS 300 765-2: April 1998Wireless 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 19: The DECT termination can be a PT or a FT or another WRS.3.2DECT abbreviationsFor the purposes of this ETS, the following abbreviations apply:ACAuthentication CodeARCAccess Rights ClassARDAccess Rights DetailsARIAccess Rights IdentityC/LConnectionlessC/OConnection OrientedCCCall ControlCICommon InterfaceCPECustomer Premises EquipmentCTACordless Terminal AdapterDCKDerived Cipher KeyDECTDigital Enhanced Cordless TelecommunicationsDIFSDECT Intermediate Fixed SystemDIPSDECT In

1 Scope
This European Telecommunication Standard (ETS) specifies that set of technical requirements for Digital
Enhanced 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 DECT
RAP FPs and Wireless Relay Stations (WRSs) if applied.
ETS 300 765-1 [16] contains the so called "Plain Old Telephone Service (POTS)" services including
analogue leased lines and 64 kbit/s bearer service. ETS 300 765-1 [16] also provides for optional mobility
features by supporting Generic Access Profile (GAP) Portable Part (PP) subscriber terminals and CTAs
with 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 the
CTA, and support of digital leased lines. The provision of the mentioned services is not mandated by this
ETS, 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 access
Profile (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 necessary
additional features (e.g. Operation, Administration and Maintenance (OA&M)) are listed and explained in
this ETS.
In addition, this ETS defines additional features, services, procedures, etc. for the CTA and the FT, which
are provision mandatory either in the CTA or in the FT, as well as some elements that are provision
optional but still process mandatory. These features in particular define the operation and maintenance of
CTAs in relation to the provided service (profile) in a public network.

3 Definitions, abbreviations and symbols
3.1 DECT definitions
For the purposes of this ETS, the following definitions apply:
authentication: The process whereby a DECT subscriber is positively verified to be a legitimate user of a
particular FP.
NOTE 1: Authentication is generally performed at call set-up, but may also be done at any other
time (e.g. during a call).
bearer service: A type of telecommunication service that provides a defined capability for the
transmission of signals between user-network interfaces.
NOTE 2: The DECT user-network interface corresponds to the top of the network layer (layer 3).
C-plane: The control plane of the DECT protocol stacks, which contains all of the internal DECT protocol
control, but may also include some external user information.
NOTE 3: The C-plane stack always contains protocol entities up to and including the network
layer.
call: All of the Network (NWK) layer processes involved in one network layer peer-to-peer association.
NOTE 4: Call may sometimes be used to refer to processes of all layers, since lower layer
processes are implicitly required.
Cordless Terminal Adapter (CTA): Physical grouping that contains a DECT portable termination and a
line interface.
Fixed Part (DECT Fixed Part) (FP): A physical grouping that contains all of the elements in the DECT
network between the local network and the DECT air interface.
NOTE 5: A DECT FP contains the logical elements of at least one FT, plus additional
implementation specific elements.
DECT network: A network that uses the DECT air interface to interconnect a local network to one or
more portable applications. The logical boundaries of the DECT network are defined to be at the top of the
DECT network layer.
NOTE 6: A DECT Network is a logical grouping that contains one or more fixed radio
terminations plus their associated portable radio termination. The boundaries of the
DECT network are not physical boundaries.
DECT intermediate fixed system: A logical grouping that contains all the functions between the DECT DI
reference point and the reference point on the fixed side of the DECT air interface.
NOTE 7: The DECT Intermediate Fixed System (DIFS) = FT + (local network up to the fixed
side ISDN reference point (including fixed side Interworking Unit (IWU))), see
ETR 056 [14].
DECT intermediate portable system: A logical grouping that contains all the functions between the
DECT DI reference point and the ISDN S reference point on the portable side of the DECT air interface.

ETS 300 765-2: April 1998
NOTE 8: The DECT Intermediate Portable System (DIPS) = Portable radio Termination (PT) +
(Portable Application (PA) up to the portable side ISDN S reference point (including
portable side IWU)), see ETR 056 [14].
Fixed Radio Termination (FT): A logical group of functions that contains all of the DECT processes and
procedures on the fixed side of the DECT air interface.
NOTE 9: A FT only includes elements that are defined in the DECT Common Interface (CI)
standard. This includes radio transmission elements together with a selection of layer
2 and layer 3 elements.
handover: The process of switching a call in progress from one physical channel to another physical
channel.
NOTE 10: There are two physical forms of handover, intra-cell handover and inter-cell handover.
incoming call: A call received at a CTA.
inter-cell handover: The switching of a call in progress from one cell to another cell.
internal handover: Handover processes that are completely internal to one FT. Internal handover
reconnects the call at the lower layers, while maintaining the call at the NWK layer.
NOTE 11: The lower layer reconnection can either be at the Data Link Control (DLC) layer
(connection handover) or at the MAC layer (bearer handover).
interoperability: The capability of FPs and CTAs, that enable a CTA to obtain access to teleservices in
more than one location area and/or from more than one operator (more than one service provider).
Interworking Unit (IWU): A unit that is used to interconnect subnetworks.
NOTE 12: The IWU will contain the interworking functions necessary to support the required
subnetwork interworking.
intra-cell handover: The switching of a call in progress from one physical channel of one cell to another
physical channel of the same cell.
Local Network (LNW): A telecommunication network capable of offering local telecommunication
services.
NOTE 13: The term does not include legal or regulatory aspects, nor does it indicate if the
network is a public network or a private network.
location area: The domain in which a CTA may receive (and/or make) calls as a result of a single
location registration.
location registration: The process whereby the position of a DECT PT is determined to the level of one
location area, and this position is updated in one or more databases.
NOTE 14: These databases are not included within a DECT FT.
MAC Connection (CONNECTION): An association between one source MAC Multi-Bearer Control
(MBC) entity and one destination MAC MBC entity. This provides a set of related MAC services (a set of
logical channels), and it can involve one or more underlying MAC bearers.
mobility class 1: Local area applications, for which terminals are pre-registered off-air with one or more
specific fixed parts, and establishment of service and user parameters is therefore implicit, according to a
profile-defined list.
mobility class 2: Private and Public roaming applications for which terminals may move between fixed
parts within a given domain and for which association of service parameters is explicit at the time of
service request.

ETS 300 765-2: April 1998
outgoing call: A call originating from a CTA.
Portable Application (PA): A logical grouping that contains all the elements that lie beyond the DECT
network boundary on the portable side.
NOTE 15: The functions contained in the PA may be physically distributed, but any such
distribution is invisible to the DECT network.
Portable Part (DECT Portable Part) (PP): A physical grouping that contains all elements between the
user and the DECT air interface. PP is a generic term that may describe one or several physical pieces.
NOTE 16: 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 processes
and procedures on the portable side of the DECT air interface.
NOTE 17: A PT only includes elements that are defined in the DECT CI standard. This includes
radio transmission elements (layer 1) together with a selection of layer 2 and layer 3
elements.
Radio Fixed Part (RFP): One physical sub-group of a FP that contains all the radio end points (one or
more) that are connected to a single system of antennas.
registration: An ambiguous term, that should always be qualified. See either location registration or
subscription registration.
service type A: Low speed frame relay, with a net sustainable throughput of up to 24 kbits/s, optimized
for bursty data, low power consumption and low complexity applications such as hand-portable
equipment.
service type B: High performance frame relay, with a net sustainable throughput of up to 552 kbits/s,
optimized for high speed and low latency with bursty data. Equipment implementation the Type B profile
shall inter-operate with Type A equipment.
service type C: Non-transparent connection of data streams requiring Link Access Protocol (LAP)
services,
