SIST ETS 300 183/A1 E1:2003 is the SIST adoption of ETS 300 183/A1 Edition 1 from ETSI for Integrated Services Digital Network (ISDN) conference call, add-on (CONF) supplementary service. It specifies one clarification to the service description: how CONF interacts with Malicious call identification (MCID), so implementers and testers can handle conference-call behavior consistently.

What does SIST ETS 300 183/A1 E1:2003 specify?

SIST ETS 300 183/A1 E1:2003 specifies an amendment to the ISDN Conference call, add-on (CONF) supplementary service description. Its scope is narrow: it clarifies the interaction between CONF and MCID.

The amendment is organized as a change to one subclause in the base standard, ETS 300 183 (1992), specifically clause 8.12. The foreword says the amendment contains changes to one subclause to resolve the interaction case between the two supplementary services.

What are the key requirements of SIST ETS 300 183/A1 E1:2003?

This amendment changes the behavior of CONF when MCID is involved. The practical effect is that conference management must respect who is using MCID and what information may be registered.

• Conference controller restriction - The conference controller cannot invoke MCID for conferees within the conference. In practice, the controller must not use the conference call itself as the path for identifying a conferee.
• Private communication first - To activate MCID, the conference controller should first create a private communication with the user to be identified. This means the identification step must be separated from the open conference context.
• Conferee invocation rule - If a conferee invokes MCID, only the connection to the conference controller is to be registered. This limits the identification data to the controller link.
• No registration of other conferees - When MCID is used by a conferee, information about the other conferees shall not be registered. This matters for privacy and for how call records are handled.
• Interaction clarification - Clause 8.12 replaces a broad "no impact" statement with role-specific behavior for the conference controller and conferees. Implementers need to code and test the two roles separately.

What terms does SIST ETS 300 183/A1 E1:2003 define?

• ISDN - Integrated Services Digital Network, the telecom environment covered by the service description.
• CONF - Conference call, add-on, the supplementary service that lets a call include multiple parties.
• MCID - Malicious call identification, the supplementary service referenced in the amendment.
• Conference controller - The user who sets up and manages the conference call.
• Conferee - A participant in the conference other than the conference controller.
• Supplementary service - An optional network service added to the basic telephony service.
• Stage 1 - The service-description level indicated in the document keywords.

Who uses SIST ETS 300 183/A1 E1:2003?

This amendment is used by people who design, implement, document, or test ISDN supplementary services. That includes telecom network operators, switch and platform vendors, protocol and service engineers, and test labs.

Quality teams and buyers can also use it to check whether a system handles conference calls and MCID interactions in the way the standard expects. In practice, it helps when writing service logic, reviewing call-record behavior, or verifying user-role handling in a conference.

What changed in SIST ETS 300 183/A1 E1:2003 from the previous edition?

SIST ETS 300 183/A1 E1:2003 modifies ETS 300 183 (1992). The amendment changes one subclause, clause 8.12, to clarify the interaction between CONF and MCID.

Which standards are used with SIST ETS 300 183/A1 E1:2003?

• ETS 300 183 (1992) - The base standard that this amendment modifies. The amendment is read together with that service description.

What does the SIST ETS 300 183/A1 E1:2003 document contain?

The document contains the amendment front matter, the foreword, transposition dates, the replacement text for clause 8.12, and the document history. The technical content is concentrated in one changed passage that explains how MCID behaves for a conference controller and for conferees.

It is a short amendment rather than a full service description. For implementation work, the key value is the clarified behavior text in clause 8.12 and the role split between controller and conferee.
