The Steering Committee Releases NEDU (SR NEDU) made its final decision concerning the new GAT planning on Monday 29 January. You will thus be able to start testing connectivity as of next Monday.
EDSN and the system integrator re-confirmed that they expect the Nexus central hub to be ready on 31 January. As a result, the Functional Acceptance Test (FAT) can be started by the lead group of market parties on 5 February. This will take place once EDSN has completed the FAT.
GAT phase 1
Phase 1 of the User Acceptance Test (GAT) will start on 5 February together with the FAT performed by the lead group of market parties. This will involve market parties testing connectivity with Nexus. This phase has been separated from other phases of the GAT and will last a total of 4 weeks.
Instructions for connection
Market parties have been divided into groups for all phases of the GAT. Grouping and planning can be found on mijnNEDU. You will also find technical instructions needed for connection. Do you require extra assistance? Then use the EDSN support offered via firstname.lastname@example.org. On the day of your group’s GAT, you can also obtain extra connection support from EDSN and the system integrator on-site in Amersfoort.
GAT phases 2, 3 and 4 as of 5 March
The next phases of the GAT will start once the lead group FAT has officially been completed. Communication via Nexus will be tested in phases 2 and 3. Phase 4 will involve checking whether AS4 notifications are passed on to recipients in the correct format. According to the new planning, these phases will start on 5 March and not 12 March, as mentioned in the provisional version of the new GAT planning. A new decision-making moment for the SR NEDU will be scheduled prior to the start of phases 2, 3 and 4.
