SIST EN 300 092-1 V2.1.1:2004 is the SIST version of the ETSI European Standard for Integrated Services Digital Network (ISDN) Calling Line Identification Presentation (CLIP) over the Digital Subscriber Signalling System No. one (DSS1) protocol. It specifies the stage 3 protocol, so it tells public network and terminal implementers how the calling party number, and where available the calling party subaddress, are carried to the called user.

What does SIST EN 300 092-1 V2.1.1:2004 specify?

SIST EN 300 092-1 V2.1.1:2004 specifies the stage 3 signalling procedures and switching functions for CLIP at the T reference point, or the coincident S and T reference point, in the public ISDN. It also covers the case where the service is provided through a private ISDN at the T reference point.

The scope is focused on DSS1 protocol handling for CLIP. It does not extend the service to non-ISDN telecommunications networks.

The document is organized into clauses for scope, references, definitions, service description, operational requirements, coding, signalling procedures, interworking, timer values, and SDLs. The annexes add signalling flows, a normative network option, terminal interworking notes, change history, and bibliography.

What are the key requirements of SIST EN 300 092-1 V2.1.1:2004?

SIST EN 300 092-1 V2.1.1:2004 requires the network to pass calling line identity information in the SETUP message as part of basic call control. In practice, implementers need to make sure the calling party number, and when present the calling party subaddress, are handled consistently from the originating side to the destination side.

Originating network handling

SIST EN 300 092-1 V2.1.1:2004 says the originating network inserts CLIP information into SETUP messages. If the calling user provides no calling number, the network uses the default number associated with the access. If the calling user provides a number, the network verifies only that it belongs to the range allocated to that user, unless a special arrangement applies.

When no special arrangement applies, the network checks the numbering plan identifier and the type of number, discards unsupported coding, and sets the screening indicator according to the screening result. This matters because the called user may see a network-provided number, a verified user-provided number, or a completed number depending on what the network can validate.

Special arrangement and presentation rules

SIST EN 300 092-1 V2.1.1:2004 treats special arrangements differently: user-provided numbers are not screened, but the network still passes the information onward. The calling party subaddress, if present, is passed transparently. The presentation indicator from CLIR is also forwarded to the destination exchange.

Destination network handling

SIST EN 300 092-1 V2.1.1:2004 requires the destination network to include the calling party number information element only when the called user subscribes to CLIP and presentation is allowed. If presentation is restricted or the number is not available due to interworking, the network sends an indication instead of a full number and omits the digits field.

Interworking cases and network option

SIST EN 300 092-1 V2.1.1:2004 also covers calls from non-ISDN networks and interworking with private ISDNs. Annex B defines a network option where two calling party number information elements may be delivered when the number is user-provided, not screened, and presentation is allowed. That option is additive and does not affect terminals or public ISDNs that do not support it.

What terms does SIST EN 300 092-1 V2.1.1:2004 define?

• Integrated Services Digital Network (ISDN) - The network context for the service, using the ISDN numbering and signalling model.
• Calling Line Identification Presentation (CLIP) - The supplementary service that presents the calling party identity to the called user.
• Calling Line Identification Restriction (CLIR) - The related service that controls whether calling identity may be presented.
• Digital Subscriber Signalling System No. one (DSS1) - The protocol used at the user-network interface for signalling.
• Served user - The called user who subscribes to presentation of calling line identification.
• Calling user - The user who originates the call and whose identity may be presented.
• Special arrangement - An agreement where customer-supplied calling party numbers are not screened by the public ISDN.
• Default number - The agreed network-side number used when the calling user does not provide usable calling number information.

Who uses SIST EN 300 092-1 V2.1.1:2004?

SIST EN 300 092-1 V2.1.1:2004 is used by public ISDN operators, switch and signalling designers, terminal manufacturers, and interoperability test teams. It is also relevant to private ISDN implementers that connect to the public network, because it defines how CLIP behaves at the interface and how calling party identity is forwarded, restricted, or replaced.

In practice, these users apply the standard when configuring SETUP message handling, screening indicators, presentation indicators, and number coding rules. Quality and acceptance teams use it when checking that calling line identity is delivered consistently across basic calls and interworking scenarios.

What changed in SIST EN 300 092-1 V2.1.1:2004 from the previous edition?

SIST EN 300 092-1 V2.1.1:2004 replaces ETS 300 092-1 (1992) and EN 300 092-1 V1.2.4. The changes stated in the document are:

• conversion to EN layout
• replacement of references to ETS 300 102 with EN 300 403
• substitution of non-specific references to basic standards where the latest version is intended
• addition of handling for the CLIAPRI (ISUPv4) value “presentation restricted by network” to support Anonymous Call Rejection (ACR)

Which standards are used with SIST EN 300 092-1 V2.1.1:2004?

SIST EN 300 092-1 V2.1.1:2004 relies on several standards and companion parts to define the service context and the related signalling behavior:

• ITU-T I.411 - Reference configurations for ISDN user-network interfaces
• ITU-T I.130 - The three-stage method used to describe the service
• ITU-T I.112 and ITU-T I.210 - ISDN vocabulary and service description principles
• ITU-T E.164 and ITU-T E.163 - Numbering plan rules used for calling numbers
• ETSI EN 300 403-1 - Basic call control signalling and number/subaddress coding
• ETSI EN 300 195-1 - Supplementary service interactions
• ETSI EN 300 089 and ETS 300 091 - Stage 1 and stage 2 CLIP/CLIR service specifications
• ITU-T Z.100 - SDL notation used for the dynamic descriptions

The foreword also names Parts 2 to 6 of the same CLIP deliverable as the conformance and test-related companion documents.

What does the SIST EN 300 092-1 V2.1.1:2004 document contain?

SIST EN 300 092-1 V2.1.1:2004 contains operational procedures, coding rules, and SDL diagrams for originating and destination network behavior. Clause 8 and its tables show how the network maps user-provided and network-provided numbers, screening indicators, and presentation indicators to the information sent onward.

Annex A provides signalling flows, Annex B gives the optional two-information-element delivery method, and Annex C describes public and private ISDN terminal interchangeability. Clause 13 includes SDL figures for the originating and destination network processes, which are used for implementation and conformance testing.
