Technical requirements for the handover interfaces for the execution of telecommunications surveillance

1 Scope of application

This technical specifications document describes the technical requirements and options for the handover interfaces between the equipment of the Communication Service Providers (CSPs) and the equipment of the Post and Telecommunications Surveillance Service (PTSS) for the provision of information requests, real-time interception, historical data (retroactive interception) and emergency paging. It specifies how the respective ETSI technical specifications apply to the different administrative and technical handover interfaces in Switzerland.

Some of the administrative and technical handover interfaces are not standardised by ETSI and are therefore specified in a proprietary manner in this document.
