Availability and schedules of the customer simulation
The CBF customer simulation environment (IMS23) is connected to the T2S Pre-Production environment (UTEST). The comprehensive processing of test cases demands the availability of both test environments. Additionally, the test schedule that is applicable for a desired test day (that is, either T2S Synchronised Standard Day, T2S Change Request Test Day or T2S Release Day) must be considered for a successful execution.
The below graphic provides a forecast for the different customer simulation periods until January 2020.
- During the CBF Free Simulation customers can execute test cases on their demand.
- For CBF Main Releases a Guided Simulation will be offered, if the scope of the new service requires dedicated test cases.
Based on the CBF maintenance schedule for the simulation environments, IMS23 will be closed for customer testing from 17 June to 12 July 2019 in order to reduce securities master data. Any ISIN supported in IMS23 having a maturity date prior to July 2018 will be removed. This activity will be conducted in IMS23 and UTEST. Customers that are permanently connected to the testing environment might receive messages related to these maintenance activities.
Based on the CBF implementation schedule, IMS23 will be closed for deployment activities of the CBF Release November 2019 and T2S Release 3.2 from 27 September to 25 October 2019.
Additional downtimes might become necessary due to deployment activities by T2S and/or CBF. According to the current schedule defined by T2S (UTEST) or CBF (IMS23), one of the two environments will therefore be additionally closed on the following days:
- 9 August 2019;
- 3 September 2019;
- 12 September 2019;
- 17 September 2019;
- 26 November 2019;
- 17 January 2020.

Instructions can be entered or transmitted depending on the customer’s connectivity mode. Customers acting in ICP mode provide their instructions via CASCADE Online functionality (HOST / PC) or use an automated connectivity channel (SWIFT, MQ, File Transfer) to IMS23. Customers acting in DCP mode transmit their instructions towards UTEST. Instructions are processed according to the T2S test schedules. Based on the test or infrastructure requirements T2S will run the processing day using the
T2S Synchronised Standard Day, that is, the general applicable daily test schedule;
T2S Change Request Test Day, which is required for T2S dedicated test cases;
T2S foresees the usage of this schedule on 10 September 2019.
T2S Release Day, which is defined for installation procedures required by the T2S Actors;
In the week prior the deployment of a major release, the recycling period will be set to one T2S Settlement Day for matched and unmatched instructions. The reset to the standard values (five T2S Settlement Days for unmatched instructions and 63 days for matched instructions ) will take place after the successful deployment in UTEST.
