Replacing the bridge cable

The standard UHK bridge cable is essentially a telephone handset cord. It features 4P4C jacks on its end. You can make / get made an alternative cable very easily and cheaply. The following criterias apply:

  1. The cable must utilize 4P4C jacks on its end.
  2. The cable must feature 4 wires to connect each of the 4 pins of the jacks.
  3. The wiring of the jacks must be cross-over, not straight-through. This means that the opposite pins of the jacks must be connected. This is easy to tell because the colors of the wires of the jacks are visible, so their order should be the opposite. Please see the following picture:

Telephone handset cords must always satisfy 1 and 2. They generally also satisfy 3 but not necessarily, so it's worth checking. Length shouldn't be an issue. Even several meter long cables should work.
