SIST EN 302 403 V8.0.1:2003 is the Slovenian adoption of ETSI EN 302 403 Version 8.0.1. It gives the Stage 1 service description for the GSM Cordless Telephony System (CTS), Phase 1, within the Digital cellular telecommunications system (Phase 2+) (GSM). The document defines how CTS is intended to work for users, CTS operators, GSM operators, and fixed-network connections.
What does SIST EN 302 403 V8.0.1:2003 specify?
SIST EN 302 403 V8.0.1:2003 specifies the service aspects of CTS, including how a GSM terminal can use a cordless CTS-FP to reach a fixed network or a GSM network. It focuses on a residential, single-cell first phase with speech teleservice support and DTMF handling.
The scope includes later-phase support where services are clearly defined, such as SMS, subscriber authentication, and GSM supplementary services on the CTS radio interface. It excludes the physical layers of the GSM-CTS fixed-network interface.
The document is organized into clauses on scope, references, definitions, service description, normal procedures, de-activation, exceptional procedures, charging aspects, and cross-phase compatibility. Informative annexes cover later phases and change history.

What are the key requirements of SIST EN 302 403 V8.0.1:2003?
SIST EN 302 403 V8.0.1:2003 requires a simple installation and enrolment process before service can start. In practice, the CTS-FP must be connected, enrolled with operation data such as the Generic Frequency List (GFL), and then one or more CTS-MSs must be enrolled before they can attach and use service.
The standard defines six CTS-MS operation modes, including CTS only, GSM only, automatic selection, and two parallel modes. This matters because the user can choose whether the handset prefers CTS or GSM, and the CTS-MS must show the selected mode and current coverage.
SIST EN 302 403 V8.0.1:2003 allows one CTS-MS to be enrolled with several CTS-FPs, but only one attachment at a time. It also requires support for multiple CTS-MSs on one CTS-FP, with at least 8 CTS-MSs attachable to the same CTS-FP.
The service rules cover CTS-roaming and subscription control. The CTS-FP owner needs a valid CTS subscription, materialized by an FP-SIM, and the CTS operator controls which CTS-MSs may enroll or attach depending on the roaming level.
Call handling is defined for CTS-MS originated and terminated calls, including number conversion between GSM formats and fixed-network formats. This is important because the CTS-FP must translate dialled numbers, route emergency calls correctly, and support group or individual alerting on incoming calls.
Radio coexistence rules require the CTS-FP to operate only on allowed frequencies from the GFL and to minimize interference with GSM and other CTS systems. The CTS-FP also has BCCH-like functionality to reveal the presence of CTS, page terminals, accept access requests, support intracell handover, and synchronize.
Security requirements are a major part of the standard. CTS enrolment and attachment use mutual authentication with CTS-specific secret keys, local CTS signalling and user data must be protected against unauthorized eavesdropping, and the GSM operator must be able to identify the IMEI and IFPEI.
What terms does SIST EN 302 403 V8.0.1:2003 define?
SIST EN 302 403 V8.0.1:2003 defines several key terms that structure the service model.
- FP Enrolment - the procedure that loads a CTS-FP with the data needed for CTS operation.
- MSEnrolment - the first association of a CTS-MS with a CTS-FP so the MS can access that CTS-FP.
- Attachment - the step that lets an enrolled CTS-MS make and receive calls through a CTS-FP.
- Generic Frequency List (GFL) - the list of ARFCN values the CTS-FP is allowed to use.
- CTS-FP - the fixed part that provides cordless coverage and links CTS-MSs to the fixed network or GSM network.
- CTS-MS - a GSM mobile station with CTS capability.
- FP-SIM - the SIM in the CTS-FP that materializes the CTS subscription.
- CTS-roaming - the right for an additional CTS-MS to be enrolled to a CTS-FP initialized to another operator.
Who uses SIST EN 302 403 V8.0.1:2003?
SIST EN 302 403 V8.0.1:2003 is used by CTS operators, GSM operators, and equipment designers who need to implement or evaluate CTS service behavior. It also matters to fixed-network operators and integrators because the CTS-FP can connect to PSTN/ISDN or to a GSM network.
Terminal and system manufacturers use it to design enrolment, attachment, call setup, alerting, mode selection, security, and MMI behavior. Regulators use it to understand licensed and licence-exempt operation, frequency control, and the limits on CTS service deployment.
What changed in SIST EN 302 403 V8.0.1:2003 from the previous edition?
Annex B records changes such as introducing the FP-SIM for CTS subscription management, replacing “registration” with “attachment”, clarifying licence-exempt operation, and extending the concept to CTS-FP connected to PLMN. The publication version is 8.0.1, following the Release 1999 Version 8.0.0 specification upgrade.
Which standards are used with SIST EN 302 403 V8.0.1:2003?
SIST EN 302 403 V8.0.1:2003 relies on several GSM and ISDN references for the details it builds on.
- GSM01.04 - abbreviations and acronyms used in GSM documents.
- GSM02.07 - Mobile Stations features.
- GSM02.09 - security aspects, including authentication and secure storage.
- GSM02.30 - MMI rules for the Mobile Station.
- GSM02.81 and GSM02.96 - line identification and name identification supplementary services.
- GSM03.40 - Short Message Service (SMS).
- ETS 300 111, ETS 300 109, ETS 300 110 - ISDN telephony and bearer service descriptions for speech and audio.
- EN 301 144-1 - signalling application for mobility management service on the alpha interface.
What does the SIST EN 302 403 V8.0.1:2003 document contain?
SIST EN 302 403 V8.0.1:2003 contains a system overview, service aspects, radio coexistence principles, security requirements, and the normal procedures for enrolment, attachment, call handling, maintenance, and de-activation. It also sets out charging aspects and cross-phase compatibility.
The detailed procedure clauses describe how a CTS-FP is initialized, how CTS-MSs are enrolled and de-enrolled, and how calls are set up and routed. The document also includes number conversion rules between GSM and fixed-network formats.
Figure 1 illustrates the CTS concept when the CTS-FP is connected to PSTN. Annex A lists future CTS services to consider in later phases, such as CTS-CTS handover and data/fax services, while Annex B records the document’s revision history.
