T2S Release 3.1 – Scope

Based on the T2S status reporting in April 2019, with the T2S Release 3.1 the resolution of 13 Problem Tickets is envisaged for a delivery in production. Further three tickets have been prioritised by the T2S Operational Managers Group (OMG) and show the status “Candidate for T2S Release 3.1". These tickets are currently being checked and can be authorised for the deployment.

CBF’s assessment related to these Problem Tickets shows that the fixes will not require software changes in CBF. More details are available in the attached file that provides the latest information about the related PBIs that might have impact on CBF’s customers acting in ICP and / or DCP mode. Customers are recommended to validate these scope elements and check whether operational and / or functional modifications in their procedures are required. Therefore, the file shows from the entire scope elements:

  • Eight PBIs that are already scheduled and will be deployed according to the T2S Service Transition Plan;
  • Two PBIs that are flagged as “Candidate for T2S Release 3.1”.

In urgent cases and if priority is given, further functional updates might be authorised for this deployment date. Since the scope for T2S Release 3.1 is not final yet, CBF intends to publish a latest list of prioritised Problem Tickets in the week before the simulation starts in the T2S Pre-Production environment (UTEST).

T2S Release 3.1 – Transition plan

The Market Infrastructure Board (MIB) will decide on the deployment of T2S Release 3.1 in production once the expected results have been shown during testing. On Tuesday, 10 September 2019, the final decision, known as “Go/No-Go Decision”, is to be made.

The deployment of T2S Release 3.1 into production is foreseen for the business day Monday, 23 September 2019. The implementation of the software will take place during the weekend within the T2S maintenance window. Meaning that currently no changes in the T2S Operational Day are expected; neither for the end of day (“EoD”) procedure on Friday, 20 September 2019, nor for the start of the business day, Monday, 23 September 2019.

The below table provides an overview of the important T2S milestones within the upcoming months:

Customer simulation

The simulation activities will be conducted in a “free simulation mode”. The already established static data for CBF accounts and the related connectivity settings in the CBF customer simulation environment (IMS23) remain unchanged.

Irrespective of whether CBF has to modify its software, CBF will maintain its link to UTEST so that customers can test on their demand. According to the ECB planning, the updated software will be installed on Friday, 9 August 2019 in UTEST.
