The publication of DB4 marks the close of the Detailed Level Specification (DLS) phase of the Switching Programme. This is a major milestone in the delivery of the Switching Programme.
This letter describes the suite of published products included within DB4 which are available on our website. In summary, DB4 includes:
- Centralised Switching Service (CSS) Design and Delivery products: These products focus on how the CSS will operate, service management and plans for delivery.
- End to End (E2E) Design products: These products describe how the new switching arrangements will operate for all market participants once implemented.
- E2E Delivery products: These products describe the delivery plans for the new arrangements and the roles and requirements of market participants.
- E2E and CSS Security Products: These products describe the information security and data privacy measures of the new switching arrangements. We are not currently making these publically available. We will consider further whether publishing parts of these documents would be of value.
These products will be of particular interest to those industry actors who are actively involved in the current switching processes or are considering entering the market.
