I have done a lot of work with Krone and the adaptor you mention is not Krone but made by someone else to fit into a Krone type of installation for voice blocks at one end and into the front of a panel at the other,normally with a RJ 45 size plug. It is normally used for testing,the RJ plug to go into a tester.
From the Krone block,you should have wires going to the back of the patch panel or the jack at the workstation.
These adaptors can also be found for 110 blocks.
It seems to me you don't know the nomencalture for the items your describing,so the help you get may be off somewhat.
At first you wrote:
I have 4 cables,
Green
Brown
Yellow
White
Are you talking about cables or pairs? (that is the colors of the wires in the cable(s)?
Then you wrote:Every other RJ11 I look at has,
1. Yellow
2. Green
3. Red
4. Black
These are the colors of the wires inside the jack (or plug) configured for voice applications.
The Krone adaptor you mention has no relation to the others,other than the wires mentioned first,so you may want to match your green to the RJ yellow, the brown to RJ greem,the yellow to RJ red and the white to RJ black.
