Technical requirements for the handover interfaces for the execution of telecommunications surveillance
Once the interception order has been activated the CSP sends back the filled-in order form as a signed and encrypted attachement. The CSP shall use the CREATEResponse action in the XML file (see details in section 4.3.3.1.5).
PTSS will acknowledge the reception of the filled in order form to the CSP by sending a simple email response with no content. No signing and encryption is necessary for this step.
