Connect the RJ-45 to telco clips test leads to the pairs: black to tip(A) and red lead to ring(B)

The line is connected. The modems begin to train on the lines automatically.

You may see both lines sync, drop, and then re-sync again. This is typical for bonded lines. The
modems include a test probe that syncs both pairs, drops, and then re-syncs in bonded mode.
If one of the pairs is not capable of bonding, or the pairs do not bond, a red error message box
appears.
