Draft of the howto
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 you cable.

'''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 that you got the correct wires. Cut off the other wires we do not need them (yet).

'''Three:'''
Sort your twinax plugs to make sure you build them in the right order. ;)BR
We used heat shrink tube to stabilize our cable around the plugs.
'''Four:'''
Now you can put everything on the first part of the cable and assemble it. Use a soldering-iron to fixate the each of the two pins of the plug with your wires.

'''Five:'''
Repeat step '''three''' and '''five''' to build the second plug.

'''Done.'''
