适用范围
Foreword This amendment to TBR 12 (1993) has been produced by the Business TeleCommunications (BTC) Technical Committee of the European Telecommunications Standards Institute (ETSI). This amendment changes TBR 12 (1993) 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).
