Foreword
This European Telecommunication Standard (ETS) has been produced by the Transmission and
MuItiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS specifies the physical and electrical characteristics of hierarchical interfaces based on CCITT
Recommendation G.703 [2] but it does not intend to preclude the use of interfaces covered in other
standards.
The aim of this ETS is to provide inter-vendor and inter-operator compatibility.
The conformance testing requirements corresponding to the specifications contained in this ETS are to be
specified in a different ETS.
Physical parameters for optical interfaces for the Synchronous Digital Hierarchy (SDH) are to be specified
in a different standard which is under development.

1 Scope
This ETS describes the requirements for the physical and electrical parameters of interfaces based on
CCITT Recommendations G.702 [1], G.703 [2] and G.707 [3] for interconnection of digital network
elements:
- in-station (i.e. for distances below a few hundred metres);
- using metallic (symmetrical or coaxial) pairs;
- at 64, 2 048, 8 448, 34 368 and 139 264 kbit/s hierarchical levels of the Plesiochronous Digital
Hierarchy (PDH) and at the first level of the Synchronous Digital Hierarchy (SDH) (STM-1 at
155 520 kbit/s).
This ETS also describes the requirements for the physical and electrical parameters of the 2 048 kHz
synchronisation interface.
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 amendment or revision. For undated references the latest
edition of the publication referred to applies.
