== Howto build your E1<>RJ45 cable == We used a Cat-7 Ethernet cable to build our E1<>RJ45 cable to connect the BTS with the BSC. Things you need: * one Cat-7 Ethernet cable * two twinax plugs (BR2) * some heat shrink tube * soldering-iron * multimeter (optional) * a sharp knife :) === Step-by-step guide === '''One:''' Take your cable and cut off one of the RJ45 connectors. Now use a ruler and make a slice so you can strip around 15 cm from your cable. [[Image(IMG_0960-1.JPG, 15%)]] [[Image(IMG_0960-2.JPG, 15%)]] '''Two:''' Split the wires from your cable. We need pin 1 and 2 for '''RX''' (green white/green) and pin 4 and 5 for '''TX''' (blue white/blue), you can use a multimeter if you are not sure you got the correct wires. Cut off the other wires we do not need them (yet).

Use a soldering-iron to fixate each of the two pins of the plug with your wires. You do not have to worry about the polarity inside the twinax plug.

'''Done.''' [[Image(IMG_0960-19.JPG, 15%)]] '''Done.'''
