SIST EN 301 240 V1.1.3:2003 is the SIST adoption of an ETSI DECT profile for Point-to-Point Protocol (PPP) interworking. It specifies how Digital Enhanced Cordless Telecommunications (DECT) equipment can carry PPP packets for dial-up internet access and general multi-protocol datagram transport, including remote LAN access, in roaming mobility class 2 applications. The profile is aimed at non-voice equipment and the InterWorking Unit (IWU) that connects DECT to a fixed network.
What does SIST EN 301 240 V1.1.3:2003 specify?
SIST EN 301 240 V1.1.3:2003 defines a DECT data services profile built on Class 2 data service profiles. It covers the DECT air interface, the interworking to a fixed network, and the signalling needed for PPP transport between a Portable Part (PP) and a peer entity.
The document is organized into general service description, layer requirements, management entity requirements, generic interworking conventions, and two annexes. Annex A gives IWU-Attributes codings, and Annex B gives service-specific interworking conventions for native PPP, modem service, and ISDN service.
| Annex | What it covers |
|---|---|
| Annex A | IWU-Attributes codings for interworking-specific signalling |
| Annex B | Interworking conventions to specific fixed network services |
| B.1 | Native PPP service |
| B.2 | Modem service, including octet-stuffed and bit-stuffed framing |
| B.3 | ISDN service, including bit-synchronous and octet-synchronous framing |
What are the key requirements of SIST EN 301 240 V1.1.3:2003?
SIST EN 301 240 V1.1.3:2003 requires implementations to follow the DECT service type C, mobility class 2 behaviour from ETS 300 651 for the Physical (PHL), Medium Access Control (MAC), Data Link Control (DLC), and Network (NWK) layers. In practice, this means the profile does not replace the DECT base layers - it constrains how they are used for PPP interworking.
The profile sets the service objectives for point-to-point SDU transfer, service change and negotiation, segmentation of higher layer user information, optional in-band user control signalling, and optional encryption. For a buyer or integrator, these are the functions that must be supported at system level.
The U-plane requirements in Clause 7 are important because they require segmentation support for higher layer user messages and set a maximum LU3 information field size for conforming FP and PP implementations. That matters when checking whether a device can carry the intended PPP packets without breaking them into incompatible pieces.
Clause 8 requires the call control entity to support packet mode procedures and ties that support to the DECT call control conditions defined for service type C. In practice, this is what allows the PPP connection to be established and maintained over DECT as packet traffic rather than voice traffic.
Clause 9 gives management behaviour for suspending and resuming calls. The Management Entity (ME) decides when to suspend or resume, but it must consider PPP packet activity, pending segmentation data, LAP-U idle state, and peer-to-peer signalling. The same clause also says Link Quality Monitoring timers should be set so they do not interfere with suspension and resumption handling.
Clause 10 defines the PPP data exchange rules. The LU3 Service Data Unit (SDU) can be type A, B, or C depending on the service, and all Portable Parts claiming conformance must support type A. Clause 10.2 also defines the control frame used to signal PPP lower layer up/down status from the Fixed Part (FP) or IWU to the PP.
Clause 10.3 covers call control interworking in both directions:
- PP originated call handling
- PP terminated call handling
These procedures map DECT CC messages to local fixed-network signalling and to the PPP layer so data transfer starts only after the lower layer is ready.
What terms does SIST EN 301 240 V1.1.3:2003 define?
- Interworking Unit (IWU) - The unit that connects subnetworks and handles the protocol mapping between DECT and the fixed network.
- InterWorking Functions (IWF) - The functions inside the IWU that perform the interworking.
- Mobility class 2 - Roaming operation where terminals move between Fixed Parts within a domain with explicit service parameter association at service request time.
- Service type C - A non-transparent data service using Link Access Procedure (LAP) services, optimized for reliability and lower complexity.
- Point-to-Point Protocol (PPP) - The packet protocol carried across the DECT profile for internet access and other datagram transport.
- Control Plane (C-plane) - The signalling side of the DECT protocol stack.
- User plane (U-plane) - The user-data side of the DECT protocol stack.
Who uses SIST EN 301 240 V1.1.3:2003?
SIST EN 301 240 V1.1.3:2003 is used by DECT terminal and base-station designers, interworking platform developers, and network engineers who need PPP transport over DECT. It also matters to test labs and conformance teams checking LU3, call control, and service-specific interworking behaviour.
Operators and integrators use it when providing roaming non-voice access to internet or private data networks. Quality managers and buyers use it to confirm that equipment supports the right DECT profile, the right annex for the target fixed-network service, and the required signalling behaviour.

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
