Overview

SIST ETS 300 061-1 E1:2005 is a Slovenian adoption of the European Telecommunication Standard ETS 300 061-1 (Edition 1), focusing on the Integrated Services Digital Network (ISDN). Specifically, it addresses the Subaddressing (SUB) supplementary service through the Digital Subscriber Signalling System No. one (DSS1) protocol at Layer 3 of the ISDN user-network interface. This standard provides the foundational protocol specification for enabling subaddressing features in ISDN environments, enhancing the addressing capabilities beyond the standard ISDN subscriber number.

Key Topics

• ISDN Subaddressing Supplementary Service (SUB):
  Expands the addressing range, allowing users to identify specific endpoints or sub-entities beyond the main ISDN number.

• DSS1 Protocol Layer 3:
  Defines signalling protocols and message flows for user-network communication at the S/T or T reference point as per CCITT I.411.

• Protocol Specification:
  Describes the procedures, information elements (such as the "Called Party Subaddress"), and operational requirements necessary for delivering subaddressing features.

• Interworking and Compatibility:
  Addresses how subaddressing functions in both public telecommunications networks and private ISDNs at the reference point, ensuring interoperability within ISDN environments.

• Supplementary Service Interactions:
  Considers how subaddressing integrates with other ISDN supplementary services such as Direct Dialling In (DDI), Multiple Subscriber Number (MSN), Calling Line Identification Presentation (CLIP), and Connected Line Identification Presentation (COLP).

Applications

Implementing the specifications from SIST ETS 300 061-1 E1:2005 delivers several practical advantages for ISDN service providers, equipment manufacturers, and enterprise users:

• Enhanced Endpoint Identification:
  Subaddressing allows a single ISDN number to support multiple applications, devices, or end-users by providing an additional layer of addressing. This is valuable in environments like corporate PBX systems or multi-tenant facilities.

• Seamless Service Provisioning:
  Facilitates flexible provisioning and withdrawal of the SUB supplementary service, either on-demand or via subscription, catering to diverse customer needs.

• Transparent Information Transfer:
  Ensures that subaddress information is conveyed transparently through the network, supporting reliable call routing to the intended endpoint without altering the basic call control procedures.

• Integration with Private ISDNs:
  Specifies behaviour for scenarios where ISDN connections traverse private branch exchanges (PBX), maintaining consistency across interconnected networks.

• Interoperability:
  By aligning with established European standards and references like ETS 300 102-1/2 and CCITT Recommendations I.411, I.130, and E.164, the protocol ensures broad compatibility across ISDN equipment and services.

Related Standards

Implementers and users of SIST ETS 300 061-1 E1:2005 should be aware of several related standards that provide complementary functionality or define supporting concepts:

• ETS 300 059: Service description from the user perspective (Stage 1).
• ETS 300 060: Functional capabilities and information flows (Stage 2).
• ETS 300 102-1/2: ISDN user-network interface layer 3 specifications and SDL diagrams for basic call control.
• ETS 300 195-1: Supplementary service interactions under DSS1.
• CCITT Recommendations:
  • I.411: ISDN user-network interfaces - reference configurations
  • I.130: Methods for service characterization
  • E.164: ISDN numbering plan
  • I.112/I.210: ISDN vocabulary and service principles

SIST ETS 300 061-1 E1:2005 is crucial for supporting advanced addressing and call management within ISDN, ensuring effective communication and service differentiation in digital networks. For ISDN equipment vendors and network operators, adherence to this protocol standard supports robust, scalable, and interoperable service delivery.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 1 of a multi-part standard covering the Digital Subscriber Signalling System No. one
(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) Subaddressing (SUB)
supplementary service, as described below:
Part 1: "Protocol specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the user";
Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma specification for the user";
Part 5: "TSS&TP specification for the network";
Part 6: "ATS and partial PIXIT proforma specification for the network".
In accordance with CCITT Recommendation I.130, the following three level structure is used to describe
the supplementary telecommunications services as provided by European public telecommunications
operators under the pan-European Integrated Services Digital Network (ISDN):
- Stage 1: is an overall service description, from the user's standpoint;
- Stage 2: identifies the functional capabilities and information flows needed to support the service
described in stage 1; and
- Stage 3: defines the signalling system protocols and switching functions needed to implement the
service described in stage 1.
This ETS details the stage 3 aspects (signalling system protocols and switching functions) needed to
support the Subaddressing (SUB) supplementary service. The stage 1 and stage 2 aspects are detailed in
ETS 300 059 (1991) and ETS 300 060 (1991), respectively.
This reprint includes all previous Corrigenda as shown in the History box at the last page.

1 Scope
This first part of ETS 300 061 specifies the stage three of the Subaddressing (SUB) supplementary
service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public
telecommunications operators at the T reference point or coincident S and T reference point (as defined in
CCITT Recommendation I.411 [1]) by means of the Digital Subscriber Signalling System No. one (DSS1).
Stage 3 identifies the protocol procedures and switching functions needed to support a telecommunications
service (see CCITT Recommendation I.130 [2]).
In addition, this standard specifies the protocol requirements at the T reference point where the service is
provided to the user via a private ISDN.
This standard does not specify the additional protocol requirements where the service is provided to the
user via a telecommunications network that is not an ISDN.
The SUB supplementary service allows the called (served) user to expand his addressing capacity beyond
the one given by the ISDN number.
The SUB supplementary service is applicable to all telecommunication services.
Further parts of this standard specify the method of testing required to identify conformance to this
standard.
This standard is applicable to equipment supporting the SUB supplementary service, to be attached at
either side of a T reference point or coincident S and T reference point when used as an access to the
public ISDN.
