Overview
SIST ETS 300 166 E1:2003 is an international standard specifying the physical and electrical characteristics of hierarchical digital interfaces for telecommunication equipment utilizing the 2 048 kbit/s-based plesiochronous or synchronous digital hierarchies. Developed by the Slovenian Institute for Standardization (SIST) and aligned with ETSI standards, it is based primarily on the internationally recognized CCITT (now ITU-T) recommendations G.702, G.703, and G.707.
The standard defines requirements for hierarchical interfaces at bit rates of 64 kbit/s, 2 048 kbit/s, 8 448 kbit/s, 34 368 kbit/s, 139 264 kbit/s, and 155 520 kbit/s, as well as the 2 048 kHz synchronization interface. It aims to ensure interoperability between equipment from different vendors and operators, supporting reliable digital transmission and multiplexing across telecommunication networks.
Key Topics
Physical and Electrical Interface Characteristics
Specifies electrical requirements such as tolerable longitudinal voltage, output signal balance, and minimum output return loss for hierarchical digital interfaces.Hierarchy Levels and Transmission Rates

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.
