Overview

SIST ETS 300 256 E2:2005 is a European Telecommunication Standard that defines the specification, functional models, and information flows for diversion supplementary services in Private Integrated Services Networks (PISN). Developed by the Slovenski inštitut za standardizacijo (SIST) and harmonized with ISO/IEC 13872, this standard supports key functionalities such as Call Forwarding Unconditional (SS-CFU), Call Forwarding Busy (SS-CFB), Call Forwarding No Reply (SS-CFNR), and Call Deflection (SS-CD). These services are vital for enhancing call handling flexibility and continuity within private telecommunication networks, streamlining business communication processes and improving response efficiency.

Key Topics

• Diversion Supplementary Services: The standard details four core diversion services for PISN environments:

  • Call Forwarding Unconditional (CFU): Routes all incoming calls to a predefined destination regardless of the current line status.
  • Call Forwarding Busy (CFB): Redirects calls to another number when the intended recipient’s line is busy.
  • Call Forwarding No Reply (CFNR): Transfers calls if there is no answer after a specified time.
  • Call Deflection (CD): Enables a called user to direct an incoming call to an alternate destination during the call setup.

• Functional Models: SIST ETS 300 256 E2:2005 uses functional models to outline how supplementary services are integrated and managed within PISN, ensuring interoperability and efficient service delivery.

• Information Flows: The standard specifies information exchanges necessary to support diversion services, ensuring clear procedures between network components and user devices.

• Conformance with International Standards: This standard adopts and modifies ISO/IEC 13872, ensuring alignment with global best practices in telecommunication network services.

Applications

The implementation of SIST ETS 300 256 E2:2005 brings several practical benefits in private telecommunication environments, particularly in enterprise and campus settings:

• Enhanced Call Management: Organizations can manage incoming calls more flexibly, ensuring critical communications are always answered or correctly redirected.
• Business Continuity: With robust call forwarding and redirection options, companies can maintain communication flow during peak times, staff absence, or network disruptions.
• User Mobility: Employees can reroute calls to alternate devices or locations, supporting remote working and seamless communication across multi-site operations.
• Customer Service Improvement: Fast, reliable call diversion ensures customer queries are addressed without unnecessary delays, increasing satisfaction.

Related Standards

For comprehensive PISN implementation and optimal supplementary service performance, the following standards are relevant:

• ETS 300 171: Defines control aspects for circuit mode basic services in private telecommunication networks.
• ETS 300 189: Covers addressing mechanisms in Private Telecommunication Networks (PTN).
• ETS 300 237: Specifies name identification supplementary services for PISN.
• ETS 300 387: Provides methods for the specification of basic and supplementary network services.
• ETS 300 475-1: Outlines reference configurations for PTN exchanges.
• ISO/IEC 13872: The international standard for diversion supplementary services, which this document aligns with and adapts for the European context.

SIST ETS 300 256 E2:2005 serves as a key resource for telecom engineers, network administrators, and anyone involved in designing or maintaining PISN infrastructures, ensuring reliable and standardized call management capabilities.

Page 2ETS 300 256: May 1996ForewordThis second edition European Telecommunication Standard (ETS) has been produced by theCommunication, Networks, and Systems Interconnection Technical Committee (TC32) of ECMA on behalfof 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 PrivateIntegrated 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 SystemsInterconnection (OSI) as defined by ISO/IEC.This particular ETS specifies the Diversion supplementary services. The Diversion supplementaryservices are:-Call Forwarding Unconditional (SS-CFU);-Call Forwarding Busy (SS-CFB);-Call Forwarding No Reply (SS-CFNR); and-Call Deflection (SS-CD).The previous (first) edition of this ETS contained a "standalone" specification of these supplementaryservices. This edition endorses an International Standard, ISO/IEC 13872, published since the publicationof the first edition of this ETS.Transposition datesDate of adoption of this ETS (doa):31 May 1996Date of latest announcement of this ETS (doa):31 August 1996Date of latest publication of new National Standardor endorsement of this ETS (dop/e):28 February 1997Date of withdrawal of any conflicting National Standard (dow):28 February 1997Endorsement noticeThe text of International Standard ISO/IEC 13872 (1995) was approved by ETSI as an ETS with agreedmodifications as given below.NOTE:New or modified text is indicated using sidebars.
