| 20 June 2007 On 19 June 2007 communications tests were carried out between the completed technical infrastructure of the SIS on the Polish side and the Central SIS System (C.SIS) in Strasburg. The tests were positive. The task assigned to Poland by the European Commission has been completed. One of important elements of implementing the Schengen acquis is the construction of the tele-informational infrastructure of the Schengen Information System (SIS). Due to delays in the implementation of the SIS II system by the EU, Portugal proposed a temporary solution in the form of SISone4All, which consists in including the new Member States temporarily in the present SIS-NET network. This will make possible the exchange of information within SIS in a very short period of time, which will allow for the abolition of internal border checks within the Schengen area, inter alia, Poland between December 2007 and March 2008.The implementation of SISone4All is a very significant project within the SIS. It consists in integrating the present and 9 new users of the information system and is a difficult project both technically and organisationally. The fundamental task is to prepare and conduct the migration of the SIS1+, SIRENE and VISION systems to the new network in a very short period of time. When taking the decision on implementing SISone4All, the European Commission set the Member States a very ambitious technical task with a high risk of failure due to time considerations and the geographical scope of the project. In Poland the activities related to that process are coordinated by the Implementing Authority for European Programmes – in the area of SIS and VIS, Grzegorz Blizniuk. In the Polish context the task of creating the technical conditions for information exchange within SISone4All was allocated to the specialists from the Department of Teleinformational Infrastructure of the Ministry of Interior and Administration and the Communications and IT Office of the National Headquarters of the Police.
