there used to be an entry on the Ameritech web site that would respond
with ISDN avail and type of switch given a specific NXX/NPA - 
The site now has more of a customer focus with some good info,
but they no longer respond with the switch type & location - 
Is this info avail anywhere else, or in some page I missed.
