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:
