The following documents explain the functional changes and upgrades we’ve made with each release, and how they affect the way our system interacts with yours. They’re aimed at your technical teams who design and build interfaces into the Openreach B2B gateway.
When we’re going to make a change, we’ll create a new document which we’ll publish before testing or release. We’ll then update this if we need to, based on our findings. So keep checking back for updates.
(We reserve the right to change functionality as part of a release, and to add a new document to reflect this.)
You can now find Functional Specification, and B2B/XML Release Documentation on iPublish, which can be found within the 'Your tools' section on your Dashboard.
