Overview

SIST EN 301 257 V1.1.1:2005 is a Slovenian national adoption of the European standard for the Recall supplementary service in Private Integrated Services Networks (PISN). This standard, developed by SIST and aligned with ISO/IEC 15051 (1997), defines the functional models and information flows required to support the recall supplementary service in private telecommunication environments. The document provides both stage 1 (service requirements and user perspective) and stage 2 (architectural and information flow) descriptions, in line with methodologies referenced in ECMA DTR/ECMA-00002 and ENV 41 005.

The Recall supplementary service enables users within a PISN to initiate, manage, and respond to recall requests, providing more flexible call handling in business and enterprise telecommunications infrastructures.

Key Topics

• Recall Supplementary Service
  Details the requirements, interactions, and processes involved in enabling a recall service within a private network. Recall allows users to conveniently re-establish a previously held or disconnected call within the PISN.

• Functional Models
  Describes the logical and architectural models used to support the recall service, ensuring interoperability and standardization across different PISN implementations.

• Information Flows
  Specifies the sequence and nature of information exchanged between network entities for the recall supplementary service, clarifying how signaling and control messages are handled within the network.

• Service Stages

  • Stage 1: Focuses on user-oriented service description and operational scenarios.
  • Stage 2: Provides an analysis of network architecture, identifying the functional entities and their interactions necessary to realize the service.

• References and Modifications
  The standard incorporates and modifies references from international standards, such as EN 300 171, ETS 300 260, and others, to better align with the European and Slovenian context.

Applications

The Recall supplementary service defined in SIST EN 301 257 V1.1.1:2005 is essential for:

• Business Telephony Systems:
  Enhancing internal communications by allowing users to quickly return or recall calls, supporting more efficient workflows.

• Private Networks (PISN):
  Facilitating advanced call control functions in corporate, academic, or government institutions operating private ISDN-based telecommunication environments.

• Vendor Interoperability:
  Providing a consistent framework for manufacturers of PISN equipment and software, ensuring products work seamlessly within multi-vendor environments.

• Network Management:
  Allowing network administrators to implement, monitor, and optimize recall functionalities as part of an organization’s overall telephony service portfolio.

Related Standards

SIST EN 301 257 V1.1.1:2005 references and aligns with several important international and European standards to ensure broad compatibility and interoperability:

• EN 300 171:
  Specification of functional models and information flows for control aspects of circuit-mode basic services within PISN.

• ETS 300 260:
  Specification for call transfer supplementary services in private networks.

• ETS 300 387:
  Methods for specifying both basic and supplementary services for private telecommunication networks.

• ETS 300 475-1:
  Reference configurations for private telecommunication network exchanges (PTNX).

• ISO/IEC 15051 (1997):
  International baseline for Recall supplementary service, with modifications reflected in the European and Slovenian standards.
