Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Access and Terminals (AT). Introduction The present do
14、cument takes advantage of progress in other areas like: ongoing studies on frequency management on local loop; ongoing studies on measurement method; uploaded information from referenced and other authorities. It facilitates a comparison among the requirements identified. For this purpose parameters
15、 like measurement bandwidth, were identified more precisely. The present version of the document was enhanced with an extended scope. The present document aims to facilitate further developments in standardization for the deployment of xDSL systems. ETSI ETSI TR 101 960 V1.2.2 (2006-01) 5 1 Scope Th
16、e present document describes and enumerates various requirements on metallic (horizontal) out of band spectrum for analogue terminals connected to the PSTN. An attempt to create an envelop of the various requirements is made and a limit for an out of band spectrum requirement protecting xDSL service
17、 is proposed to facilitate the standard convergence in this sector. 2 References For the purposes of this Technical Report (TR), the following references apply: 1 ETSI TBR 021: “Terminal Equipment (TE); Attachment requirements for pan-European approval for connection to the analogue Public Switched
