-          ISDN ("Integrated Services Digital Networks", called RNIS in France)
-          is a special type of fully digital telephone service; it's mostly
-          used to connect to your Internet service provider (with SLIP or
-          PPP).  The main advantage is that the speed is higher than ordinary
-          modem/telephone connections, and that you can have voice
-          conversations while downloading stuff.  It only works if your
-          computer is equipped with an ISDN card and both you and your service
-          provider purchased an ISDN line from the phone company.  For
-          details, read <http://www.alumni.caltech.edu/~dank/isdn/> on the WWW.
+          ISDN ("Integrated Services Digital Network", called RNIS in France)
+          is a fully digital telephone service that can be used for voice and
+          data connections.  If your computer is equipped with an ISDN
+          adapter you can use it to connect to your Internet service provider
+          (with SLIP or PPP) faster than via a conventional telephone modem
+          (though still much slower than with DSL) or to make and accept
+          voice calls (eg. turning your PC into a software answering machine
+          or PABX).
 
           Select this option if you want your kernel to support ISDN.
