Overview

SIST ETS 300 365 E2:2005 is a European Telecommunication Standard that defines supplementary services for Call Completion in Private Integrated Services Networks (PISN). The standard, maintained by the Slovenski inštitut za standardizacijo (SIST), aligns with the work of the European Telecommunications Standards Institute (ETSI) and addresses functional models and information flows for enhanced call handling capabilities within private enterprise telecommunication networks.

This edition specifies the supplementary services Call Completion on Busy Subscriber (CCBS) and Call Completion on No Reply (CCNR). Core to private network operation, these services ensure successful call completion even when the originally called party is busy or does not answer, thus improving overall communication efficiency in corporate environments.

Key Topics

• Call Completion Supplementary Services:
  Definition and principles of SS-CCBS (Completion of Calls to Busy Subscribers) and SS-CCNR (Completion of Calls on No Reply), enabling users to request automatic redial and call-back when the intended recipient becomes available.

• Functional Models:
  Specification of the processes and functional interactions required for implementation of the supplementary services across PISN, ensuring interoperability and consistency.

• Information Flows:
  Detailed models of signal and data exchange between network components during the activation and execution of call completion features.

• Integration with Telecommunication Standards:
  Conformance with ISDN concepts as promoted by the ITU-T and adherence to Open Systems Interconnection (OSI) frameworks as stipulated by ISO/IEC standards.

• Interoperability and Reference Modifications:
  Specific instructions regarding application and mapping of related standards such as ISO/IEC 13866, and relevant modifications or references to other European telecommunication standards (e.g., ETS 300 171, ETS 300 387, ETS 300 475-1).

Applications

The standards defined in SIST ETS 300 365 E2:2005 have practical application in the following scenarios:

• Business Telephony:
  Enhanced user experience in private branch exchanges (PBX) and enterprise communication platforms by ensuring important calls are not missed due to call recipient unavailability.

• Customer Service Centers:
  Automated call-back services reduce manual effort and improve response times, supporting higher satisfaction and efficiency.

• Unified Communications Solutions:
  Seamless integration of call completion services contributes to robust unified communications offerings, vital for organizations needing reliable telephony solutions.

• IT and Telecommunication Vendors:
  Equipment manufacturers and software providers can develop products conformant with European and international standards, ensuring compatibility in multi-vendor environments.

Related Standards

For comprehensive implementation and effective integration of call completion supplementary services, reference to these related standards is recommended:

• ISO/IEC 13866:
  International standard upon which this ETS is based, covering specification and information flows for similar supplementary services.

• ETSI ETS 300 171:
  Deals with functional models and specification for circuit mode basic services in Private Telecommunication Networks.

• ETSI ETS 300 387:
  Outlines methods for specification of basic and supplementary services, including terminology and procedure definitions.

• ETSI ETS 300 475-1:
  Defines reference configurations for PTN exchanges, essential for consistent deployment across network infrastructure.

These standards facilitate interoperability, maintain high quality of service, and ensure that innovations in telephony and private networking adhere to internationally recognized benchmarks.

By adopting SIST ETS 300 365 E2:2005, organizations operating Private Integrated Services Networks can assure advanced call completion capabilities, leading to greater efficiency, user satisfaction, and future-proof telecommunication solutions.

Foreword
This draft 2nd edition European Telecommunication Standard (ETS) has been produced by the
Communication, Networks, and Systems Interconnection Technical Committee (TC32) of ECMA on behalf
of its members and those of the European Telecommunications Standards Institute (ETSI).
This ETS is one of a series of standards defining services and signalling protocols applicable to Private
Integrated Services Networks (PISN). The series uses the Integrated Services Digital Network (ISDN)
concepts as developed by ITU-T and conforms to the framework of standards for Open Systems
Interconnection (OSI) as defined by ISO/IEC.
This particular ETS specifies the Call Completion supplementary services. The Call Completion
supplementary services are:
- Completion of Calls to Busy Subscribers (SS-CCBS); and
- Completion of Calls on No Reply (SS-CCNR).
The previous (first) edition of this ETS contained a "standalone" specification of these supplementary
services. This edition endorses an International Standard, ISO/IEC 13866, published since
