Knowledge Based Diagnostics (KBD) is a new test & diagnostic tool for CPs developed as a GUI presentation and an XML interface, it employs BT Wholesale's network test capability in a new way with “One Touch” test & diagnostics.
It supports an initial test to identify where the fault is e.g. on the local access or at the IP connectivity layer.
Subsequent tests are highly focused to the line condition and it is supported by new improved diagnostic flows
