Within the Switching Operator Service Definition document, the Central Switching Service (CSS) Provider (DCC) is required to provide 10 Working Days’ (WDs) notice of planned system outages. However, within the CSS Provider’s processes and the Switching Operator Change Management Process Category 3 document,

an 8 WD lead time is set out. This change seeks to address this discrepancy and align the code documentation.

The approved Solution that has been agreed under the REC is Solution Option 1, which seeks to amend the notice period from 10WD to 8WD within the Switching Operator Service Definition document.

As a result of this, the CDSP, as a Switching Data Service Provider, needs to amend processes surrounding interactions with the CSS Provider to ensure this is reflected.

Note: This will be implemented in line with the Feb 23 release
