+.Sh SYNOPSIS
+.Cd device \&"i4bcapi\&"
+.Sh DESCRIPTION
+.Nm
+is a CAPI driver for the 
+.Em isdn4bsd
+package. It sits between layer 4 of isdn4bsd and a driver for an active 
+ISDN card; currently only the
+.Xr iavc 4
+driver for the AVM B1 and T1 family of active cards is supported.
+.Sh STANDARDS
+CAPI 2.0 (http://www.capi.org/)
+.Sh SEE ALSO
+.Xr iavc 4
+.Sh AUTHORS
+The
+.Nm
+device driver was written by 
+.An Juha-Matti Liukkonen (Cubical Solutions Ltd, Finnland) Aq jml@cubical.fi .
+This manpage was written by
