   it's connected to our comcast 'gateway' gizmo.

   Be aware that FAX and DUN (dialup networking), will   
   have trouble with the bandwidth implementation of the   
   VOIP. On FAX machines, the normal 14400 Fine must   
   be switched down to 9600 and tried again. I do not know   
   what the max DUN is with an old modem. It's not likely   
   to be 43K (middle of road value, for mild impairment).   
      
   What would I practice with ? Even the FreeNet has bailed   
   on DUN, and is "selling" their own ADSL.   
      
   As long as your modem standard is not known for the   
   "spiral of death", the modem will auto-adjust to conditions.   
   I assume, when you talk of testing this stuff, you have   
   a *working* combo of branded modem and dialup pool at the destinations.   
   There were combinations of modem and front end that did not work.   
   The word "Livingston" for the front end, seemed to figure in   
   some of those pronouncements. The odds of Google allowing you   
   to find some of the old DUN help pages, why, that's equal to zero.   
      
   And as Google fouls up search, so does Bing. How ARE those   
   two coupled together ???
