Usage of CBT of the head financial organisation in the divided mode (Shared Connection) or connection through the Service bureau. Scheme of Shared Connection is developed by SWIFT for connection of affiliated organisations by parent organisation though it can be used by the foreign financial organisations. This is an effective decision which allows to focus financial streams. It leads to simplification of an operational environment of work of the organisation and cuts expenses on the maintenance of two various technical infrastructures. Connection to SWIFTNet FIN opens a way to use of advantages of other possibilities: such for example as control facilities of a network SLA and the improved support services. FIN is basic service SWIFT for message transfer. Over 7 500 financial institutions more than in 200 countries use FIN for the protected exchange of the financial information reliable and economically effective. In this case the connecting organisation bears full responsibility before SWIFT for the organisation of safe work of the connected User. The Service bureau has no right to send and receive SWIFT-message on behalf of its own so that excludes a competition with the financial organisations.
