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 second edition of ETS 300 147 (1995) supersedes the first edition of ETS 300 147 (1992).
This ETS provides inter-vendor and inter-operator compatibility and is based on ITU-T Recommendations
G.707 [1], G.708 [2] and G.709 [3].
Transposition dates
Date of latest announcement of this ETS (doa): 30 April 1995
Date of latest publication of new National Standard 31 October 1995
or endorsement of this ETS (dop/e):
Date of withdrawal of any conflicting National Standard (dow): 31 October 1995

1 Scope
This European Telecommunication Standard (ETS) specifies the hierarchical bit rates, the multiplexing
structure and the mapping schemes to be used in the transmission networks based on Synchronous
Digital Hierarchy (SDH).
2 Normative references
This ETS incorporates by dated and 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 amendment or revision. For undated references the latest
edition of the publication referred to applies.
[1] ITU-T Recommendation G.707 (1993): "Synchronous digital hierarchy bit rates".
[2] ITU-T Recommendation G.708 (1993): "Network node interface for the
synchronous digital hierarchy".
[3] ITU-T Recommendation G.709 (1993): "Synchronous multiplexing structure".
3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the definitions given in ITU-T Recommendation G.708 [2] apply.
3.2 Abbreviations
For the purposes of this ETS the following abbreviations apply.
ATM Asynchronous Transfer Mode
AU-n Administrative Unit-n
AUG Administrative Unit Group
N Normative
N/R Not Relevant
POH Path Overhead
SDH Synchronous Digital Hierarchy
SOH Section Overhead
STM-N Synchronous Transport Module-N
TU-n Tributary Unit-n
TUG(-n) Tributary Unit Group (-n)
VC-n Virtual Container-n
4 Hierarchical bit rates
The hierarchical bit rates used in the SDH transmission network shall be according to ITU-T
Recommendation G.707 [1].

5 Basic multiplexing structure
The basic SDH multiplexing structure shall be as described in figure 1.
NOTE 1: This SDH multiplexing structure is a subset of the SDH multiplexing structure defined
in ITU-T Recommendation G.709 [3].
NOTE 2: The order of transmission of information in all diagrams in ITU-T Recommendation
G.709 [3] is first from left to right and then from top to bottom. Within each byte, the
most significant bit is transmitted first. The most significant bit (bit 1) is illustrated at the
left in all diagrams.
6 Multiplexing method and mapping
The multiplexing method and mapping are given in ITU-T Recommendation G.709
