Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission
and Multiplexing (TM).
The present document is one of a family of documents that has been produced in order to provide inter-vendor and
inter-operator compatibility of Synchronous Digital Hierarchy (SDH) equipment.
The present document is part 3, sub-part 1 of a multi-part deliverable covering the Generic requirements of transport
functionality of equipment, as identified below:
Part 1-1: "Generic processes and performance";
Part 1-2: "General information about Implementation Conformance Statement (ICS) proforma";
Part 2-1: "Synchronous Digital Hierarchy (SDH) and Plesiochronous Digital Hierarchy (PDH) physical section
layer functions";
Part 2-2: "Synchronous Digital Hierarchy (SDH) and Plesiochronous Digital Hierarchy (PDH) physical section
layer functions; Implementation Conformance Statement (ICS) proforma specification";
Part 3-1: "Synchronous Transport Module-N (STM-N) regenerator and multiplex section layer functions";
Part 3-2: "Synchronous Transport Module-N (STM-N) regenerator and multiplex section layer functions;
Implementation Conformance Statement (ICS) proforma specification";
Part 4-1: "Synchronous Digital Hierarchy (SDH) path layer functions";
Part 4-2: "Synchronous Digital Hierarchy (SDH) path layer functions; Implementation Conformance Statement
(ICS) proforma specification";
Part 5-1: "Plesiochronous Digital Hierarchy (PDH) path layer functions";
Part 5-2: "Plesiochronous Digital Hierarchy (PDH) path layer functions; Implementation Conformance Statement
(ICS) proforma specification";
Part 6-1: "Synchronization layer functions";
Part 6-2: "Synchronization layer functions; Implementation Conformance Statement (ICS) proforma specification";
Part 7-1: "Equipment management and auxiliary layer functions";
Part 9-1: "Synchronous Digital Hierarchy (SDH) concatenated path layer functions; Requirements".
Parts 2 to 7 specify the layers and their atomic functions.
Parts 2 to 7 specify the layers and their atomic functions.
NOTE: The SDH radio equipment functional blocks are addressed by ETSI WG TM4.

Various of the above parts have previously been published as parts of ETS 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 doc
