SECMP0007 implementation

The Communications Services Provider (CSP) System changes for SECMP0007 will be implemented in the June 2022 SEC Release, with the associated Communications Hub firmware updates being made following this. However, there will be no associated SECMP0007 legal text implemented in the June 2022 SEC Release as the SECMP0007 document changes will be implemented in the November 2021 SEC Release. For information on the implementation approach, please visit our news page here.


SECMP0015 implementation

Only the SECMP0015 document changes for the DCC User Interface Specification (DUIS) and the Message Mapping Catalogue (MMC) will go live in this June 2022 SEC Release. This to align it with other DUIS and MMC changes due to go live in the June 2022 SEC Release and to ensure each of these documents are only uplifted once in 2022 for efficiency. The DCC System impacting changes arising from SECMP0015 and the resulting full functionality will go live in the November 2022 SEC Release.
