Overview
SIST EN 301 487-2 V1.1.1:2005 specifies the Protocol Implementation Conformance Statement (PICS) proforma for the Broadband Integrated Services Digital Network (B-ISDN) Digital Subscriber Signalling System No two (DSS2) protocol at the user-network interface, focusing on layer 3 specification for switched virtual path capability. This part of the standard builds on the protocol specification defined in EN 301 487-1 and provides a standardized method for suppliers to declare conformance to these requirements.
A PICS proforma is essential for ensuring interoperability and compliance in telecommunications systems. By using this document, manufacturers and suppliers can comprehensively declare which features and options of the DSS2 protocol have been implemented, as required for B-ISDN user-network interfaces with switched virtual paths.
Key Topics
- B-ISDN Conformance: Outlines the implementation conformance requirements for switched virtual path capability using DSS2.
- PICS Proforma Structure: Provides a structured, tabular format based on ISO/IEC 9646-7 guidelines for conformance statements.
- Identification Data: Details the required information to identify the implementation, including supplier and product specifics.
- Capability Support: Enables implementers to specify support for mandatory, optional, and prohibited protocol features.
- User and Network Roles: Contains distinct sections in the proforma for both “user” and “network” protocol entities at the user-network interface.
- Reference Integrity: Ensures correlation with relevant international references (e.g., ITU-T Q.2934, ISO/IEC standards).
- Instructions for Completion: Includes guidance for correctly filling out and interpreting the PICS tables, aimed at accurate and reproducible conformance declarations.
Applications
The PICS proforma found in SIST EN 301 487-2 V1.1.1:2005 has broad utility across the telecommunications sector:
- Product Conformance Assessment: Suppliers complete the proforma to document and demonstrate their product’s adherence to EN 301 487-1 requirements, streamlining verification by network operators and procurement bodies.
- Interoperability Testing: Provides an essential reference for test laboratories validating B-ISDN equipment for DSS2 protocol support, reducing ambiguity during multi-vendor network integration.
- Regulatory Compliance: Facilitates compliance with European and international requirements, ensuring products satisfy recognized B-ISDN user-network interface standards.
- Technical Documentation: Serves as a reference document in technical files and product literature, clarifying which protocol options are implemented or omitted.
Related Standards
SIST EN 301 487-2 V1.1.1:2005 is closely related to a range of standards and recommendations in the field of broadband ISDN and protocol conformance:
- EN 301 487-1: Protocol specification for DSS2 switched virtual path capability.
- ITU-T Q.2934: International base specification on which the European adaptation is built.
- ISO/IEC 9646-7: Guidelines for Implementation Conformance Statement proforma structures.
- EN 301 487-3 to 487-6: Documents outlining test suite structures, test purposes, and further guidance for both users and networks.
- Other related ITU-T and ISO/IEC standards relevant to ISDN data link and network layers (e.g., ITU-T Q.921, ISO/IEC 9646-1).
Practical Value
Using SIST EN 301 487-2 V1.1.1:2005 ensures that protocol implementation claims for B-ISDN DSS2 are clear, uniform, and verifiable, supporting efficient conformance testing and market access. It enables both vendors and customers in the telecommunications industry to streamline the product certification and integration process, ultimately enhancing reliability and interoperability in broadband networks.
