 \begin{enumerate}
-    \item An \textit{ADSL modem} modulates and demodulates the data using DMT and creates downstream and upstream channels.
-    \item A \textit{DSL access multiplier} does the same at the ISP side.
-    \item The typical range is $12000ft = 3657.6m$.
-    \item The router assigns the IP address from the \textit{BRAS} to the customer using the \textit{PPP} protocol.
-    \item ADSL uses $26 - 108 \kHz$ for upstream and $138 - 1104 \kHz$ for downstream.\\ Cable uses $5 - 42 \mHz$ for upstream, $54 - 450 \mHz$ for video and $550 - 750 \mHz$ for downstream.
-    \item The data from separate coaxial cables are multiplexed on a single shared medium.
-    \item Capacity sharing is realized with \textit{frequency division multiplexing} and with \textit{statistical time division multiplexing}.
-    \item No, the cable modem receives all encrypted data broadcasted by the CMTS. The CM however only extract the data from the cable which is addressed to itself.
-    \item Multiple CM fight for a minislot, CMTS assigns these minislots to the competing CMs. The CMs uses the assigned minislot for data transmission to the CMTS.
-    \item The cable modem on the customer premise is configured and controlled by the CMTS using DOCSIS and layer 1 and 2 protocols.
+    \item For DSL there is a \emph{splitter} for splitting Voice from Data and an \textit{ADSL modem} modulates and demodulates the data using DMT and creates downstream and upstream channels.\\
+    For cable we need a \emph{cable modem}.
+    \item A \textit{DSL access multiplier} in combination with a \emph{splitter} does the same at the ISP side.\\
+    For cable it is the \emph{Head end}.
+    \item The range for ADSL is up to $\sim 5km$ (bandwidth decreasing). For DOCSIS (cable) the range is up to $\sim 170 km$ (good bandwidth for higher ranges but also decreasing).
+    \item The IP is assigned via PPP by the BRAS and Router.\\
+    For cable the CMTS provides the IP via DHCP.
+    \item ADSL uses $26 - 108 \kHz$ for upstream and $138 - 1104 \kHz$ for downstream (values from lecture). With Annex B it is upstream: $138 -276 kHz$, downstream: $276-1104 / - 2208$ \footnote{according to \url{https://en.wikipedia.org/wiki/G.992.3\#/media/File:ADSL_annex_overview.svg}}\\ Cable uses $5 - 42 MHz$ for upstream, $54 - 450 MHz$ for video and $550 - 750 MHz$ for downstream.
+    \item Both (cable and DSL) are built hierarchically, on higher levels shaded media are used (e.g. common coaxial cable for neighbourhood for cable)
+    \item Capacity sharing is realized with \textit{frequency division multiplexing (FDM)} (DSL) and with \textit{statistical time division multiplexing} (cable).
+    \item For DSL yes, the signal is demultiplexed before it reaches the consumer.\\
+    For cable no, the cable modem receives all encrypted data broadcasted by the CMTS. The CM however only extract the data from the cable which is addressed to itself.
+    \item Multiple CM fight for a minislot, CMTS assigns these minislots to the competing CMs. The CMs uses the assigned minislot for data transmission to the CMTS.\\
+    In DSL the data are just multiplexed (FDM).
+    \item The cable modem on the customer premise is configured and controlled by the CMTS using DOCSIS and layer 1 and 2 protocols.\\
+    For DSL the BRAS is the corresponding instance.
