Hi Every one
I have been tasked with setting up an office in Brazil and the person that is helping up procure the hardware wrote me back and asked me a question about the WAN card for the 1921 router. I have never dealt with DSL before and I wanted to know if someone can tell me what is the difference between the Annex A,B,and M on the cards and does it really matter which one I pick. Below are the links that she sent me back in the email asking the questions and any help would be greatly appreciated.
