 for answering machine support. The driver is part of the isdn4bsd package.
+.Pp
+The lower six bits of the drivers's minor number is used to specify a
+unit number, wheras the upper two bits specify a functionality.
+.Pp
+Functionality zero is the usual telephony data stream i/o driver.
+.Pp
+Functionality one is used to enable commands to dial out and hang up and
+receive responses about the state of the dial out progress and status.
+This commands may change in the future, for details see the file
+.Em i4b_tel_ioctl.h
+and the 
+.Xr isdnphone 1
+utility.
+.Pp
+The telephony data stream comes out of the line in a bit-reversed format,
+so the 
+.Nm
+driver does the bit-reversion process in any case.
+.Pp
+Additionally, the user can specify to do A-law to u-law, u-law to A-law
+or no conversion at all in the i4btel driver by using the
+.Xr isdntelctl 8
+utility.
