SECMP0007 implementation approach

The SEC changes and Data Services Provider (DSP) elements for SECMP0007 will be implemented on 4 November 2021 (November 2021 SEC Release). The Communication Services Provider (CSP) changes will be delivered via a Communications Hub firmware release, targeted for the June 2022 SEC Release.

Note, Prepayment Meter Interface Devices (PPMIDs) and Home Area Network (HAN) Connected Auxiliary Load Control Switches (HCALCSs) can only be updated over-the-air (OTA) once the Communications Hub Release has been implemented. This is due to take place from June 2022.
