Foreword
This European Telecommunication Standard (ETS) has been produced by the Transmission and
Multiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS has been produced in order to provide inter-vendor and inter-operator compatibility for transport
functionality of equipment.
This ETS consists of 8 parts as follows:
Part 1: "Generic processes and performance" (ETS 300 417-1-1);
Part 2: "SDH and PDH physical section layer functions" (ETS 300 417-2-1);
Part 3: "STM-N regenerator and multiplex section layer functions" (ETS 300 417-3-1);
Part 4: "SDH path layer functions" (ETS 300 417-4-1);
Part 5: "PDH path layer functions" (ETS 300 417-5-1);
Part 6: "Synchronization distribution layer functions" (ETS 300 417–6-1);
Part 7: "Auxiliary layer functions" (ETS 300 417-7-1);
Part 8: "Compound and major compound functions" (ETS 300 417-8-1).

1 Scope
This European Telecommunication Standard (ETS) 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 this ETS needs to be
describable as an interconnection of a subset of these functional blocks contained within this ETS. The
interconnections of these blocks need to obey the combination rules given. The generic functionality is
described in the ETS 300 417-1-1 [1].
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references subsequent amendments to, or revisions of, any of these publications
apply to this ETS only when incorporated in it by amendments or revisions. For undated references the
latest edition of the publication referred to applies.
