[jQuery] ajaxcfc - if ajax call fails - how does it get handled?


I have a page that submits checkboxes as they are checked on the way
down a form.
The click hides the checkbox for a loading gif, submits the ID via
ajax, and on its return changes the loading icon to a tick image.
What I want to know is how to handle a failure of the ajax request.
currently I have the following:
$.AjaxCFC({
         url: "/packages/ajax/primaryInvitee.cfc",
         method: "addInvitee",
         data: options,
         success: function(r) {
            thisCheck = "check_" + r.LOGINID;
            thisLoad = "load_" + r.LOGINID;
            if(r.RESULT > 0){
                $('#'+thisLoad).attr("src","/pics/icon_tick_grey.gif");
            }else{
                $('#'+thisCheck).css("display","");
                $('#'+thisLoad).css("display","none");
            }
            //sDumper(r);
         }
I cant find a failure equivalent to "success:".
What about a timeout? How would I handle this?
Thanks in advance!
