The Contractor shall provide BRASS Enhancement 1 Engineering Support Services contributing to the preparation, testing, validation, and harmonized implementation of BRASS Enhancement 1 services across NATO Nations.

This includes, but is not limited to, the following:

Technical documentation development:

• Characterization of BLOS AP use cases, in accordance to the BRIPES service delivery concept, and definition of configuration baselines;
• Prepare and maintain technical documentation containing the STANAG 5066 complete protocol stack parameters and configuration required for the implementation of BRASS Enhancement 1 services;
• Interoperability analysis on different implementations of STANAGs, namely STANAG 4538 and 5066, and documentation of discrepancies found in the configuration of different Editions of those STANAGs;
• Optimization of configuration baselines based on identified performance criteria;
• Ensure technical documentation is complete, consistent, traceable, and aligned with applicable NATO standards and NCIA engineering practices;
• Identify configuration dependencies resulting from different STANAG editions, vendor implementation specificities, and national implementation approaches;
• Maintain version control and configuration management of all engineering documentation and technical artefacts.

Testing and validation activities:

• Setup of a testing environment for verification and validation of configuration baselines, including modems back-to-back, usage of HF channel simulators and over-the-air transmission;
• Analysis on interoperability and interfacing challenges between STANAG 5066 and interfacing modules part of the IP over HF architecture. This includes troubleshooting of identified standard interface issues and conformance
  testing;
• Develop testing approaches and validation plans supporting the implementation of BRASS Enhancement 1 services;
• Participation, as requested, in experimentation and demonstration activities in events held within NATO countries. Configure and validate service parameters using NCIA reference systems and laboratory equipment, simulated HF
  environments, and, where required, over-the-air testing capabilities;
• Support the establishment and maintenance of representative testing environments for the verification and validation of BRASS Enhancement 1 service configurations;
• Perform technical testing and interoperability validation of service configurations prior to publication of implementation guidance;
• Analyse test results, identify interoperability issues, configuration inconsistencies, and implementation risks;
• Recommend corrective actions and optimized service configurations where required;
• Document testing activities, validation results, engineering findings, and recommendations.

Service Instructions development:

• Development of Service Instructions for BRIPES, including full protocol stack for the different information services, i.e. formal messaging (ACP 127 and STANAG 4406 Annex E), e-mail, chat and web services;
• Ensure Service Instructions are aligned with the technical documentation, validated configurations, and applicable NATO standards;
• Maintain consistency between Service Instructions, technical documentation, and approved implementation baselines;
• Update Service Instructions following validation activities, stakeholder feedback, or changes to technical requirements.

Engineering analysis and technical support:

• Perform engineering assessments of proposed service configurations and implementation approaches;
• Analyse interoperability impacts associated with differing STANAG 5066 editions, vendor-specific implementations, and national deployment environments;
• Analyse interoperability and interface challenges affecting the BRIPES architecture and provide recommendations to resolve identified issues;
• Provide engineering recommendations supporting harmonized implementation across NATO Nations;
• Support technical coordination with NCIA stakeholders and other NATO organizations involved in BRASS Enhancement 1 implementation;
• Contribute engineering expertise to implementation planning, technical reviews, and working groups as required.

Stakeholder coordination and reporting:

• Liaise with NCIA technical authorities and relevant NATO stakeholders, providing engineering inputs and consolidated technical documentation;
• Prepare technical reports, engineering analyses, implementation guidance, and briefing material;
• Participate in technical meetings, workshops, validation activities, and engineering reviews, technical demonstrations, and experimentation activities as required;
• Report progress, technical risks, issues, and recommendations in accordance with NCIA governance processes.
