Various of the above parts have previously been published as parts of EN 300 417.
They have been converted to parts of EN 300 417 without technical changes, but some editorial changes have been
necessary (e.g. references). In particular:
- Parts 2-1 and 3-2 have been modified to take account of editorial errors present in edition 1.
- Part 1-1 has had its title change of to align with other parts published at a later date.
Also note that in the meantime parts 8-1, 8-2 and 8-3 have been stopped.

1 Scope
The present document specifies a library of basic building blocks and a set of rules by which they are combined in order
to describe transport functionality of equipment. The library comprises the functional building blocks needed to
completely specify the generic functional structure of the European transmission hierarchies. Equipment which is
compliant with the present document needs to be describable as an interconnection of a subset of these functional
blocks contained within the present document. The interconnections of these blocks need to obey the combination rules
given. The generic functionality is described in the present document.
