SIST EN 300 356-16 V3.1.3:2003 is the ETSI European Standard for the ISDN User Part (ISUP) version 3 on the international interface, Part 16 for the Call Hold (HOLD) supplementary service. It specifies the stage 3 signalling procedures and switching functions needed to support HOLD in ISDN, mainly for European public telecommunications operators and implementers of SS7/ISUP networks.

What does SIST EN 300 356-16 V3.1.3:2003 specify?

SIST EN 300 356-16 V3.1.3:2003 specifies additional generic procedures for the Call Hold (HOLD) supplementary service beyond the basic call procedures. It is the stage 3 part of the service description, so it focuses on protocol behaviour, message handling, and switching functions rather than user-level service description.

The standard applies to the international ISDN interface using Signalling System No. 7 (SS7) and ISUP. It does not add protocol requirements for delivery through a non-ISDN network or for the national signalling interface.

The document is organized around the ETSI-approved text of ITU-T Recommendation Q.733, clause 2 (1993), with added Scope and Normative references text at the start of clause 2. It also includes informative Annex ZA.

What are the key requirements of SIST EN 300 356-16 V3.1.3:2003?

SIST EN 300 356-16 V3.1.3:2003 says that HOLD is a stage 3 supplementary service under the CCITT Recommendation I.130 model. In practice, that means the standard is about the signalling rules and exchange functions needed to implement the service, not the service description itself.

• HOLD allows a user to interrupt an active call and later, if desired, restore communications. For implementers, this means supporting a controlled pause and resumption of an existing connection.
• HOLD applies to all circuit-mode basic telecommunication services. In practice, operators and switch vendors need to consider every circuit-mode service where call suspension and recovery may be offered.
• The standard applies only to the international interconnection side of ISUP. This matters because the text keeps the exchange functions, formats, codes, and actions, but leaves national-interface requirements outside its scope.
• Formats, codes, and procedures marked for national use are retained for informative purposes. If a national network or operator network supports them, the standard indicates they should be supported in that same way on the international side.
• The specification includes the behaviour of originating and destination local exchanges. In practice, this is the detail needed to design switch logic and test interoperability at both ends of the call.
• Annex ZA gives the coding of the compatibility information for the generic notification parameter. That matters when implementing message compatibility and parameter handling in switches and gateways.

What terms does SIST EN 300 356-16 V3.1.3:2003 define?

• ISDN - Integrated Services Digital Network, the telecommunication network environment for the standard.
• ISUP - ISDN User Part, the SS7 protocol part used for ISDN call control on the international interface.
• SS7 - Signalling System No. 7, the signalling system carrying the protocol procedures.
• HOLD - Call Hold, the supplementary service that lets a user interrupt and later resume a call.
• Stage 3 - The protocol and switching-function level in the CCITT I.130 service model.
• Circuit-mode basic telecommunication services - The service category to which HOLD applies in this standard.
• DSS1 - Digital Subscriber Signalling No. one, named in the related references for the user-side protocol.

Who uses SIST EN 300 356-16 V3.1.3:2003?

SIST EN 300 356-16 V3.1.3:2003 is used by European public telecommunications operators, ISDN/SS7 network engineers, and switch vendors that implement ISUP on international interconnections. It is also relevant to gateway designers and test teams checking interoperability for supplementary services.

In practice, these users apply it when defining call-control behaviour, building exchange software, verifying message handling, and aligning international network implementations of HOLD.

What changed in SIST EN 300 356-16 V3.1.3:2003 from the previous edition?

SIST EN 300 356-16 V3.1.3:2003 approves ITU-T Recommendation Q.733, clause 2 (1993), with ETSI modifications. ETSI adds a Scope and Normative references section at the start of clause 2 and replaces several references throughout the text with ETSI and EN documents.

The document also notes that new or modified text is marked with sidebars, underlining, and strike-out. Annex ZA is included as an informative addition on compatibility-information coding.

Which standards are used with SIST EN 300 356-16 V3.1.3:2003?

SIST EN 300 356-16 V3.1.3:2003 cites the following references and companion parts:

• CCITT Recommendation I.130 - provides the service-characterization model used for stage 1, stage 2, and stage 3 descriptions.
• ETS 300 121 - provides the earlier ISUP version 1 baseline for international ISDN interconnections.
• ETS 300 139 - gives the HOLD service description.
• ETS 300 140 - gives the HOLD functional capabilities and information flows.
• ETS 300 141-1 - gives the DSS1 protocol for HOLD.
• EN 300 356-1 - covers ISUP version 3 basic services and the modified Q.761 to Q.764 material.
• EN 300 356-2 - covers ISUP version 3 ISDN supplementary services and the modified Q.730 material.
• EN 300 403-1 - gives the DSS1 signalling network layer for circuit-mode basic call control.

What does the SIST EN 300 356-16 V3.1.3:2003 document contain?

SIST EN 300 356-16 V3.1.3:2003 contains the ETSI foreword, the approval of the ITU-T clause 2 text with modifications, a normative reference list, and informative Annex ZA. The document also includes a table that maps the original ITU-T references to their ETSI/EN replacements.

Annex ZA provides the coding of compatibility information for the generic notification parameter, including the instruction indicators used for message handling. That makes the annex useful for implementation and interoperability work, especially when configuring how exchanges treat parameters and notifications.
