I found a circuit and instructons of type J and it seems there is some different way of making and clearing a call in CB mode.

Yes, you may have several telephones on the line.

In CB mode the telephone has a capacitor in series to block DC in on hook mode, and in off hook mode something to carry dc, often a coil.
Moast field telephones use batteries even in cb mode.
