Technicial and Process Documents

We’ve identified a set of essential documents called ‘mandatory’ that everyone involved in the OTS process must become familiar with. Additionally, we have a collection of advisory documents, thoughtfully created by industry participants with TOTSCo’s facilitation to offer industry guidance. It’s crucial to note that these documents do not serve as legal or regulatory advice, nor do they bear the endorsement of Ofcom, ICO, or TOTSCo. As a result, they will consistently undergo updates and enhancements to evolve and better cater to the industry’s requirements.
