SIST EN 300 094 V2.1.1:2005 is the Slovene adoption of ETSI EN 300 094 Version 2.1.1 in the telecommunications series. It defines the stage 1 service description for the Integrated Services Digital Network (ISDN) Connected Line Identification Presentation (COLP) supplementary service, from the user’s point of view, for public telecommunications operators and related private ISDN interworking.

What does SIST EN 300 094 V2.1.1:2005 specify?

SIST EN 300 094 V2.1.1:2005 specifies the overall service description of COLP in pan-European ISDN. It explains what the calling party receives, how the connected line identity is handled, and how public ISDNs interact with private ISDNs and other networks.

The document is organized into scope, references, definitions and abbreviations, description, procedures, intercommunication considerations, interactions with other supplementary services, and two informative annexes.

Annex	What it covers
Annex A	Terminal interchangeability between public and private ISDNs
Annex B	Extended screening option for COLP

The scope also sets boundaries: charging principles are outside the document, and service interactions not listed in clause 8 are outside its scope.

What are the key requirements of SIST EN 300 094 V2.1.1:2005?

Service purpose and access

SIST EN 300 094 V2.1.1:2005 states that COLP gives the calling party the possibility to receive identification of the connected party. It applies to basic access and primary rate access, so it is relevant to both smaller and larger ISDN interfaces.

The network shall deliver the connected line identity when the call is accepted, even if the terminal cannot process that information. In practice, this means the service is network-controlled rather than dependent on terminal capability.

Number handling and screening

SIST EN 300 094 V2.1.1:2005 says the connected line identity may include the national ISDN number, the country code and possible other indications for international calls, and optionally a subaddress. The subaddress is transparently transported by the network, which matters because the network is not responsible for its content.

The connected user may provide the connected line identity on call acceptance. The public ISDN screens that number unless a special arrangement applies, and then marks the result accordingly as user provided, verified and passed, or as user provided, not screened.

If the user gives no number, or screening fails, the public ISDN inserts a default number and marks it as network provided. This is important in operation because callers still get an identifying number, but not always the original user-supplied one.

Interworking and service interactions

SIST EN 300 094 V2.1.1:2005 requires private ISDNs to screen connected user information before passing a national or international E.164 number to the public ISDN. If the call crosses into a private ISDN, the private network handles its own screening first, then the public network applies its own screening unless a special arrangement exists.

COLR normally takes precedence over COLP. The calling user receives an indication that the connected line identity is unavailable when COLR blocks presentation, when signaling capability is insufficient, or when the destination network cannot provide the identity.

The document also sets interaction rules with forwarding and deflection services, freephone, multiple subscriber number, and conference services. In practice, these clauses tell operators when identity is passed, when it is hidden, and when forwarding or conference participants should not see added parties’ identities.

What terms does SIST EN 300 094 V2.1.1:2005 define?

• Connected Line Identification Presentation (COLP) - the supplementary service that presents the connected party’s identity to the calling party.
• Connected Line Identification Restriction (COLR) - the supplementary service that restricts presentation of the connected line identity.
• Screening - the network process that checks whether user-provided information is acceptable.
• Special arrangement - an agreement that lets customer-supplied connected party ISDN numbers bypass public ISDN screening.
• Default number - the ISDN number used when the user provides none or screening is unsuccessful.
• Partial number - part of an ISDN number that helps distinguish addressable entities beyond the network boundary.
• Public Switched Telephone Network (PSTN) - the public switched telephone network referenced for interworking context.

Who uses SIST EN 300 094 V2.1.1:2005?

SIST EN 300 094 V2.1.1:2005 is used by public telecommunications operators, private ISDN operators, and service providers that offer COLP. It is also relevant to engineers and system designers implementing ISDN signaling and number screening, especially where public and private networks interwork.

Quality and acceptance teams use it to check that connected line identity is passed, screened, restricted, or replaced in the right cases. Buyers and integrators use it to verify that a proposed ISDN service or platform supports the expected COLP behavior.

What changed in SIST EN 300 094 V2.1.1:2005 from the previous edition?

SIST EN 300 094 V2.1.1:2005 updates the earlier edition with work on number screening. The foreword adds informative Annex B, which describes an extended screening option for COLP while keeping interoperability with existing implementations.

Which standards are used with SIST EN 300 094 V2.1.1:2005?

• CCITT Recommendation I.130 - gives the stage 1, stage 2, and stage 3 service description framework used by the document.
• ITU-T Recommendation I.112 - provides ISDN vocabulary definitions.
• ITU-T Recommendation E.164 - defines the ISDN numbering plan used for national and international numbers.
• ITU-T Recommendation I.210 - defines supplementary service principles and terminology.
• ETSI ETS 300 062 - provides the Direct Dialling In (DDI) service description, used for partial number context.
• ETSI ETS 300 050 - provides the Multiple Subscriber Number (MSN) service description.
• ETSI ETS 300 095 - gives the Connected Line Identification Restriction (COLR) service description.
• ETSI ETS 300 096 - gives the stage 2 functional capabilities and information flows for COLP and COLR.
• ETSI EN 300 097-1 - gives the DSS1 protocol specification for COLP.
• ECMA-155 - supports private network addressing and terminal interchangeability context.

What does the SIST EN 300 094 V2.1.1:2005 document contain?

SIST EN 300 094 V2.1.1:2005 contains the service description, procedure rules, interworking guidance, and service interaction rules for COLP. It also includes two informative annexes that explain terminal interchangeability and an extended screening option.

The body of the document is written for service specification and implementation planning, not for test methods. It gives operators and implementers the behaviors to support in call setup, screening, forwarding, restriction, and private-network interworking.
