Foreword
This amendment to ETS 300 290 (1994) has been produced by the Business TeleCommunications (BTC)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
This amendment changes ETS 300 290 (1994) as described below:
The connector type specified, conforming to ISO/IEC 10173 (1991), cannot be manufactured. Since a
standardized connector is not available, the terminal equipment is required to provide either a point for
connection of solid conductors, or solid conductors themselves. In order to allow connection to be made
using other methods, the TE is permitted to be supplied with other connection schemes (e.g. connectors).
A note is added to subclause 5.2.1.3 on output timing stating that additional sources of timing are allowed.

Date of latest publication or endorsement of this amendment (dop/e): 31 July 1996
Date of withdrawal of any conflicting National Standard (dow): 31 July 1996

"5.1 Physical characteristics
Currently no standardized connector is readily available. Consequently, the only method of connection that
can be specified in this ETS is the use of solid conductors of 0,4 to 0,6 mm. This ETS requires the TE to
be capable of presenting either a point for the attachment of unterminated solid conductors, or solid
conductors themselves (see subclause 5.1.1). It is a
