Public Services Network (PSN) technical interoperability documents and obligations for network services

These documents place technical interoperability obligations on the three kinds of PSN network service: GCNSPs, DNSPs and other PSN networks. The obligations create the effect of a single network by defining what happens at the interfaces between different suppliers' networks, and by setting out common classes of service, and some baseline expectations for performance and availability. These documents are part of the November 2015 release of the PSN obligations.
