Overview
SIST EN 300 356-31 V3.0.3:2005 is an international standard developed by the Slovenski inštitut za standardizacijo (SIST), harmonized with ETSI EN 300 356-31. This standard addresses the Integrated Services Digital Network (ISDN) and, more specifically, the Signalling System No.7 (SS7); ISDN User Part (ISUP) version 3 for the international interface. Part 31 details the Protocol Implementation Conformance Statement (PICS) proforma specification for basic services.
The main purpose of this standard is to define the conformance criteria for ISUP version 3 implementations, ensuring interoperability and validation of network nodes supporting basic ISDN services. By using the PICS proforma, vendors and operators can document and evaluate which capabilities have been implemented and to what extent they conform to the relevant ISUP protocol specifications.
Keywords: ISDN, Signalling System No.7, ISUP, PICS, protocol conformance, SS7, interoperability, basic services, telecommunications, standardization
Key Topics
Protocol Implementation Conformance Statement (PICS):
- Provides a standardized template for suppliers to declare protocol capabilities supported by their ISUP implementations.
- Facilitates comparison and validation during procurement and interoperability testing.
ISUP Version 3 Conformance:
- Focuses on the basic services as specified in ISUP version 3, forming the basis for call control and signalling functionality at the international interface.
- Ensures the minimum required interoperability for essential call setup, management, and teardown procedures across different exchanges.
Interoperability and Validation:
- Detailed roles and capabilities tables allow vendors and operators to identify areas of compatibility and potential issues.
- Supports validation testing for all exchange types implementing ISUP version 3, streamlining troubleshooting and integration.
Standardized Documentation:
- The proforma ensures consistent, complete, and clear documentation of implementation details, supporting both internal quality assurance and regulatory compliance in the telecommunications sector.
Applications
Network Equipment Supplier Evaluation:
- Enables service providers and telecommunication operators to assess vendor compliance with ISUP version 3 standards before deployment.
- Assists in RFP responses and technical due diligence by providing an objective, standardized checklist for protocol support.
Interoperability Testing:
- Essential tool for test labs and integration projects involving multiple vendors or cross-border ISDN services.
- Reduces risk of interoperability failures by highlighting optional, mandatory, and conditional protocol features and capabilities.
Regulatory and Standards Compliance:
- Facilitates documentation required for regulatory audits and certifications relevant to ISDN and SS7 implementations.
- Guarantees adherence to European and international telecommunications standards.
Product Development and Quality Assurance:
- Guides software and hardware development teams in implementing compliant ISUP stacks.
- Assists QA teams in verifying that products meet mandatory requirements for ISUP basic services.
