How can I create a BRI loop testing cable.

[silvakizir]

I've managed to create a PRI loop for testing purposes of the interface in a RJ45 Jack Plug by connecting a wire from PIN 1 to PIN 4 and a wire from PIN 2 to PIN 5 and it works perfectly.

Does anyone know how to make a testing BRI loop cable?

I've connected a wire from PIN 3 to PIN 4 and Wire from PIN 5 to PIN 6 with no success.

I've also tried a connection with a wire from PIN 3 to PIN 5 and from PIN 4 to PIN 6 also with no success.
