I don't know what the letters for 727s stand for, but letters following the type of airplane usually refer to what optional safety equipment that the plane has installed in it. This can be anything from navigational aids to emergency equipment. I believe the letters you said have to do with communication.

If you have never designed an airplane part before, let the real designers do the work!
