<p>The present invention relates to an arrangement (10), for connecting high speed digital subscriber lines, comprising a digital subscriber line access multiplexer (1) which is adapted to be in communication with a distribution arrangement (6) interconnecting external trunk lines and internal subscriber lines. The distribution arrangement (6) is adapted to comprise or communicate with a detecting arrangement (11) adapted to detect presence of a high frequency digital signal and a connector arrangement (7) which in a second state is adapted to connect, or enable connection, of subscriber lines and a high frequency signal interface. In a first state it is adapted to disable/disconnect subscriber lines from a high frequency signal interface. The distribution arrangement (6) comprises switching or activating means for activating the second state of the connector arrangement (7) at detecting the presence of a high frequency signal.</p> |
