41 driver interfaces the IP subsystem of the operating system with the
42 isdn4bsd package so that a transport of IP packets over an ISDN link
45 The driver is just a glue layer between the
47 backend and the ISDN4BSD package and needs the
49 driver configured into the kernel.
51 The network interfaces provided by this driver are named
53 where <n> is a number between 0 and count-1 from the kernel config line.
55 For configuration of the i4bsppp driver, either the
57 utility is used or the driver can be configured via
63 In case an IP packet for a remote side arrives in the driver and no
64 connection is established yet, the driver communicates with the
66 daemon to establish a connection.
