Overview

SIST EN 300 238 V1.3.1:2005 is a European standard adopted by the Slovenian Institute for Standardization (SIST) detailing the inter-exchange signalling protocol for Private Integrated Services Networks (PISN). The document specifically addresses the name identification supplementary service, building upon and modifying ISO/IEC 13868:2003. As part of the larger PSS1 protocol suite (commonly known as QSIG), this standard defines procedures that enable the exchange of user name information between different exchanges within a private network.

This version incorporates:

• UNICODE name coding, ensuring international character set compatibility
• ASN.1 migration, updating data structure definition methodology
• A new procedure for delayed sending of name information, enhancing flexibility in name identification across network nodes

Key Topics

The core areas covered by SIST EN 300 238 V1.3.1:2005 include:

• Name Identification Supplementary Service:

  • Facilitates the presentation of calling and connected party names (CNIP/CONP)
  • Ensures consistent and standardized handling of name information across network exchanges

• Signalling Protocol at the Q Reference Point:

  • Specifies message formats and procedures for transmitting name information
  • Supports seamless interoperability between network exchanges in PISN

• UNICODE Name Coding:

  • Supports transmission of user names in multiple linguistic scripts
  • Aligns with international data exchange requirements

• ASN.1-Based Data Structures:

  • Standardizes representation of protocol messages for efficient parsing, validation, and interoperability

• Procedure for Delayed Name Information:

  • Introduces processes for name data delivery when not immediately available, enhancing network reliability

Applications

This standard offers practical value in various telecommunications environments:

• Enterprise Telephony:

  • Enables comprehensive caller identification in multi-site private networks
  • Supports advanced supplementary services for corporate PBXs and integrated telephony solutions

• Interoperability:

  • Ensures compatibility between different vendors’ PISN equipment via standardized inter-exchange signalling
  • Facilitates integration with ISDN-based and next-generation voice systems

• Enhanced User Experience:

  • Provides end-users with clear, accurate display of caller and connected party names
  • Increases trust and reduces ambiguity in internal and external communications

• Support for Internationalization:

  • Transfers names with special or non-Latin characters, meeting global business and communication needs

• Network Evolution:

  • The standard’s ASN.1 migration and Unicode support prepare networks for future enhancements and broader compatibility

Related Standards

SIST EN 300 238 V1.3.1:2005 is part of a comprehensive suite of PISN and telecommunication standards. Related and referenced standards include:

• EN 300 172: Circuit-mode basic services for PISNs
• EN 300 171: Service description and functional capabilities for circuit-mode bearer services
