Extent: E+W+S+N.I.

Pursuant to Article 4(1)(c) of the SIS II legal instruments SIRENE Bureaux shall use an encrypted virtual network dedicated to SIS II data and the exchange of data between SIRENE Bureaux for their communication. Only if this channel is not available, another adequately secured, and given the circumstances, the most appropriate means of communication may be used. The ability to choose the channel means that it shall be determined on a case by case basis, according to technical possibilities and the security and quality requirements that the communications have to meet.
Written messages shall be divided into two categories: free text and standard forms. The latter shall be set out as in Annex 3.
In order to achieve the utmost efficiency in bilateral communication between SIRENE staff, a language familiar to both parties shall be used.
The SIRENE Bureau shall answer all requests for information made by the other Member States via their SIRENE Bureaux as soon as possible. In any event a response shall be given within 12 hours.
Priorities in daily work shall be based on the category of alert and the importance of the case.
In addition, the SIRENE Bureau shall use a dedicated and secure e-mail for the exchange of all information not exchanged via forms.
