Foreword
This European Telecommunication Standard (ETS) has been produced by the Transmission and
Multiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI)
in order to provide inter-vendor and inter-operator compatibility of Synchronous Digital Hierarchy (SDH)
equipments.
Transposition dates
Date of adoption of this ETS: 6 March 1998
Date of latest announcement of this ETS (doa): 30 June 1998
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 December 1998
Date of withdrawal of any conflicting National Standard (dow): 31 December 1998
This ETS consists of 8 parts as follows:
Part 1: "Generic processes and performance" (ETS 300 417-1-1 [8]).
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 [10]).
Part 5: "PDH path layer functions" (ETS 300 417-5-1).
Part 6: "Synchronization distribution layer functions" (ETS 300 417-6-1 [11]).
Part 7: "Auxiliary layer functions" (ETS 300 417-7-1).
Part 8: "Compound and major compound functions" (ETS 300 417-8-1).
Introduction
The atomic PDH path layer functions are defined below used in plesiochronous and synchronous
operation. They describe the functionality of PDH multiplex equipments described in the ITU-T
Recommendations G.751 [6] and G.742 [5] for signal hierarchies P4e, P31e and P22e. In addition they
describe the functionality of synchronous PDH equipment described in ETS 300 167 [2] for P12s layer
signals, and ETS 300 337 [9] for P31s and P4s signals.

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 a digital transmission equipment. The library
comprises the functional building blocks needed to completely specify the generic functional structure of
the European digital transmission hierarchy. Equipment which is compliant with this ETS can be described
as an interconnection of a subset of these functional blocks contained within this ETS. The
interconnections of these blocks should obey the combination rules given. The generic functionality is
described in the ETS 300 417-1-1 [8].
