<p>The method involves connecting two symmetric high-speed digital subscriber line (SHDSL) transceiver units by the lines. A transceiver (11) in each unit is connected with a framer mapper (12) over a user interface. A summation signal is formed from the user data, in the framer mapper, where an additional bit is provided in the user data. A frame is formed by the insertion of the additional bit in the fixed time period, where the frame includes a quality criterion.</p> |
