-	  This driver allows you to use an ISDN adapter for networking

-	  channel-bundling, callback and caller-authentication without having
-	  a daemon running.  A reduced T.70 protocol is supported with tty's
-	  suitable for German BTX.  On D-Channel, the protocols EDSS1

-	  ISDN support in the linux kernel is moving towards a new API,
-	  called CAPI (Common ISDN Application Programming Interface).
-	  Therefore the old ISDN4Linux layer will eventually become obsolete.
-	  It is still available, though, for use with adapters that are not
-	  supported by the new CAPI subsystem yet.

-	  This provides CAPI (the Common ISDN Application Programming
-	  Interface) Version 2.0, a standard making it easy for programs to
-	  access ISDN hardware in a device independent way. (For details see
-	  <http://www.capi.org/>.)  CAPI supports making and accepting voice
-	  and data connections, controlling call options and protocols,
-	  as well as ISDN supplementary services like call forwarding or
-	  three-party conferences (if supported by the specific hardware
-	  driver).
-
-	  Select this option and the appropriate hardware driver below if
-	  you have an ISDN adapter supported by the CAPI subsystem.
