ETSIEN 301 240 V1.1.3 (1998-06)51ScopeThe present document defines 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 that build upon and extend each other,aimed at the general connection of terminals supporting non-voice services to a fixed infra-structure, private and public.The present document is intended for use in roaming applications and so specifies mobility class 2. It thus specifies therequirements on the Network (NWK) layer Call Control (CC) and Mobility Management (MM) entities, to provide fullpublic services.The present document builds upon services offered by the data service profiles as defined in ETS 300 701 [9] andETS 300 651 [8]. It specifies an interworking profile for non-voice equipment with roaming mobility, providingPoint-to-Point Protocol (PPP) transmission to allow dial-up internet access and general multi-protocol datagramtransport. PPP packet transfers on the DECT air interface are specified via a high efficient DECT packet transmissionprotocol. However, interworking to the fixed network may be via a number of interface protocols, including X.25, framerelay, Asynchronous Transfer Mode (ATM), and traditional circuit switched voice band modem and Integrated ServicesDigital Network (ISDN) connection.The present document defines the specific requirements on the Physical (PHL), Medium Access Control (MAC), dataLink Control (DLC) and NWK layers of DECT. The standard also specifies Management Entity (ME) requirements andgeneric interworking conventions which ensure the efficient use of the DECT spectrum.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".[7]EN 300 175-7: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 7: Security features".SIST EN 301 240 V1.1.3:2003

A typical application is theon-demand access to an internet service provider. The DECT air interface will be accessed by means of the standardprocedures already defined by the C.2 data services profile, ETS 300 651 [8]. A PP wishing to access this service shallrequest the PPP profile by means of the standard DECT signalling, specifying also the address of the peer entity, and themethod of encapsulation.The Interworking Unit (IWU), if necessary, shall set up a point-to-point connection through the transport network. Whensuch a connection is established, IWU shall encapsulate PPP packets in the way selected by the user.4.2Service objectivesThe profile has the following service objectives:Table 1Offered servicesStatuspoint-to-point SDU transfer PP-FPYespoint-to-point SDU transfer FP-PPYesService change and negotiationYesData streamingOptionalSegmentation of higher layer user informationMandatoryin-band user control signallingOptionalEncryptionOptionalSIST EN 301 240 V1.1.3:2003
