Foreword

This European Telecommunication Standard (ETS) was produced by the Transmission and Multiplexing

(TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).

This ETS aims to meet urgent requirements of network operators and equipment manufacturers who are

designing equipment to operate with an Integrated Services Digital Network (ISDN) basic rate access

user-network interface. This ETS shall replace CEPT Recommendation T/L 03-07 (November 1987).

This ETS takes into account the special requirements from ECMA Standard 103: "Physical layer at the

basic access interface between data processing equipment and private switching networks" (1987, 2nd

Edition) in Annex B.

1 Scope

This European Telecommunication Standard (ETS) specifies requirements and test principles for the ISDN

basic rate user-network interface including the physical, electrical and functional characteristics and the

information exchange with higher layers. This ensures that interface implementations in an ISDN equipment

for use with ISDN basic access is portable within Europe with regard to layer 1 interface aspects and
