(2) Screen Requirement The system screen will be designed by the CBM-NET Phase 2 application vendor and will be confirmed by CBM in the external design phase. (3) Form Requirement The STP function does not have form requirements to be considered. (4) Data and Information Requirement System-related data and information will be designed by the CBM-NET Phase 2 application vendor and will be confirmed by CBM in the external design phase. (5) External Interface Requirement The message protocol to transfer data between GW14 of FIs and GW of CBM will be SOAP/XML. There are other options such as MQ15 or FTP16 which are also used broadly. Since STP will process urgent transaction such as RTGS, SOAP/XML protocols on web service is more suitable from the viewpoint of real time capability.
