SIST ETS 300 128/A1 E1:2003 is the Slovenian adoption of ETS 300 128/A1 Edition 1 from ETSI. It amends the Integrated Services Digital Network (ISDN) Malicious Call Identification (MCID) supplementary service description to clarify how MCID interacts with the Conference call, add-on (CONF) supplementary service.

What does SIST ETS 300 128/A1 E1:2003 specify?

SIST ETS 300 128/A1 E1:2003 specifies a targeted amendment to the MCID service description for ISDN. Its scope is limited to clarifying the interaction between MCID and CONF in one subclause of the base standard ETS 300 128 (1992).

The amendment text itself is organized as a foreword, the change instruction for clause 8.8.1, and a document history. In practice, this means the document is meant to be applied to the base service description rather than read as a full standalone re-specification.

What are the key requirements of SIST ETS 300 128/A1 E1:2003?

SIST ETS 300 128/A1 E1:2003 changes the behavior described in clause 8.8.1 so that MCID and CONF are handled in a more specific way during a conference call.

Conference controller behavior

Clause 8.8.1 states that the conference controller cannot invoke MCID for conferees within the conference. In practice, the person managing the conference must not expect MCID to identify a participant directly from inside the conference call.

The clause also notes that, to activate MCID, the conference controller should first create a private communication with the user to be identified. That matters because MCID needs a separate one-to-one connection when identification is required.

Conferee behavior

Clause 8.8.1 also states that if a conferee invokes MCID, only the connection to the conference controller is registered. No information about the other conferees is registered.

In practical terms, the identification record stays limited to the link between the participant and the conference controller. This prevents MCID from exposing the other people in the conference through that action.

Interaction between MCID and CONF

This amendment exists to clarify the interaction situation between the Conference call, add-on (CONF) supplementary service and the MCID supplementary service. For implementers, the important point is that conference-call control and malicious-call identification do not behave as if they are completely transparent to each other.

The change is narrow, but it affects service logic and testing. Anyone implementing or verifying ISDN supplementary services needs to check conference-call scenarios against the updated clause 8.8.1 behavior.

What terms does SIST ETS 300 128/A1 E1:2003 define?

• Integrated Services Digital Network (ISDN) - The digital network context for the service description.
• Malicious Call Identification (MCID) - The supplementary service concerned with identifying malicious calls.
• Conference call, add-on (CONF) - The conference-call supplementary service involved in the amended interaction.
• Conference controller - The user who controls the conference call.
• Conferee - A participant in the conference call.
• Supplementary service - An added telecommunication service that extends the basic call service.

Who uses SIST ETS 300 128/A1 E1:2003?

SIST ETS 300 128/A1 E1:2003 is used by telecommunications engineers, service designers, and network implementation teams working with ISDN supplementary services. It is relevant when they need to specify, implement, or test how MCID behaves in conference-call situations.

It is also useful for operators and verification teams that check service behavior in customer networks. The amendment gives them the exact rule for what is recorded when MCID is used during a conference.

What changed in SIST ETS 300 128/A1 E1:2003 from the previous edition?

SIST ETS 300 128/A1 E1:2003 modifies ETS 300 128 (1992). The amendment changes one subclause, 8.8.1, to clarify the interaction between MCID and the Conference call, add-on (CONF) supplementary service.

Which standards are used with SIST ETS 300 128/A1 E1:2003?

• ETS 300 128 (1992) - The base MCID service description that this amendment modifies.
• ETS 300 128/A1 Edition 1 - The amendment version identified by the Slovenian adoption.

What does the SIST ETS 300 128/A1 E1:2003 document contain?

The document contains a foreword explaining that the Network Aspects (NA) Technical Committee produced the amendment and that it clarifies one interaction case between CONF and MCID. It then gives the exact replacement text for clause 8.8.1, split into the conference controller case and the conferee case.

It also records the adoption, announcement, publication and withdrawal dates for transposition, together with document history. For readers, that makes the amendment traceable and shows when the changed wording became the approved version.
