	For the downlink of variant  $\boldsymbol{\rm A}$  with  $R_{\rm B} = 2 \ \rm Mbit/s$  thus results with  $l = l_{\rm max} = 3.5 \ \rm km$:		For the downlink of variant  $\boldsymbol{\rm A}$  with  $R_{\rm B} = 2 \ \rm Mbit/s$  thus results with  $l = l_{\rm max} = 3.5 \ \rm km$:
	:$$\alpha_{\rm K}(f = {\rm 1\,MHz}) = \left [ 5.1 + 14.3 \right ] {\rm dB}/{\rm km} = 19.4\,{\rm dB}/{\rm km}\hspace{0.3cm}		:$$\alpha_{\rm K}(f = {\rm 1\,MHz}) = \left [ 5.1 + 14.3 \right ] {\rm dB}/{\rm km} = 19.4\,{\rm dB}/{\rm km}\hspace{0.3cm}\Rightarrow \hspace{0.3cm} {\rm a}_{\rm \star} = 19.4\,{\rm dB}/{\rm km} \cdot 3.5\,{\rm km} = 67.9\,{\rm dB}\hspace{0.05cm}.$$
	\Rightarrow \hspace{0.3cm} {\rm a}_{\rm \star} = 19.4\,{\rm dB}/{\rm km} \cdot 3.5\,{\rm km} = 67.9\,{\rm dB}\hspace{0.05cm}.$$

	The values for the other system variants are to be determined in subtask '''(4)'''.		The values for the other system variants are to be determined in subtask '''(4)'''.

	The development of xDSL technology began in 1995 with the first standard for $\rm ADSL$  (''Asymmetric Digital Subscriber Line''). From 2006, the faster  $\rm VDSL$  (''Very High Data Rate Digital Subscriber Line'') also came into use in Germany.
