Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document specifies the physical and electrical characteristics of hierarchical interfaces based on IUT-T Recommendation G.707 [1] but it does not intend to preclude the use of interfaces covered in other standards. The aim of the present document is to provide inter-vendor and inter-operator compatibility. The conformance testing requirements corresponding to the specifications contained in the present document are to be specified in a different EN. Physical parameters for optical interfaces for the Synchronous Digital Hierarchy (SDH) are to be specified in a different standard which is under development.

ETSI ETSI EN 300 147 V1.4.1 (2001-09)5 1 Scope The present document specifies the hierarchical bit rates, the multiplexing structure and the mapping schemes to be used in the transmission networks based on the Synchronous Digital Hierarchy (SDH). 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-speci²fic reference, the latest version applies. [1] ITU-T Recommendation G.707 (2000): "Network node interface for the synchronous digital hierarchy (SDH)". NOTE: ITU-T Recommendation G.707 (2000) [1] contains some errors which were identified in the ITU. A corrigendum to the Recommendation [G.707 Corr.1p] [2] has been published by the ITU. Refer to annex A. [2] ITU-T Recommendation G.707 Corrigendum 1 (2001). [3] ITU-T Recommendation G.702: "Digital hierarchy bit rates". 3 Definitions, abbreviations and conventions 3.1 Definitions For the purposes of the present document, the definitions given in clause 3 of ITU-T Recommendation G.707 [1] apply. NOTE: In ITU-T Recommendation G.707 [1], clause 3.15, the number of the information bits k is wrongly defined. Refer to annex A. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: AIS Alarm Indication Signal APS Automatic Protection Switching ATM Asynchronous Transfer Mode AU-n Administrative Unit-n AUG Administrative Unit Group BIP-X Bit Interleaved Parity-X CRC-N Cyclic Redundancy Check-N DCC Data Communication Channel DQDB Distributed Queue Dual Bus FDDI Fibre Distributed Data Interface FEC Forward Error Correction HDLC High-level Data Link Control MS-RDI Multiplex Section Remote Defect Indication MS-REI Multiplex Section Remote Error Indication MSF-AIS Multiplex Section FEC Alarm Indication Signal SIST EN 300 147 V1.4.1:2003

Within each byte, the most significant bit is transmitted first. The most significant bit (bit 1) is illustrated at the left in all diagrams. In clauses 4 to 10, the status of each requirement is given with reference to ITU-T Recommendation G.707 [1] with the following conventions: Normative (N): Requirements with which it is necessary to comply in order to be able to claim compliance with the present document. Not Relevant (N/R): Clause (of ITU-T Recommendation G.707 [1]) is not relevant to the present document. The present document is not an equipment specification. The fact that a requirement is defined as normative does not imply that the associated function has to be implemented but means that, if implemented, the function shall be implemented in accordance with this requirement.
