It's all over their website telling you. Just hover over any "I" symbol

.
If you click the "I" you may get a fuller listing as well, particularly on the line rental page where you get to see all the optional extras. Such as caller display, which is the only one I have.
I see doing that on the ADSLx page that the top one is Annex M.
