45 driver interfaces the IP subsystem of the operating system with the
46 isdn4bsd package so that a transport of IP packets over an ISDN link
49 The driver is just a glue layer between Serge Vakulenko's sppp
50 backend and the ISDN4BSD package.
52 Beginning with i4b version 0.95 (and only for
56 the sppp subsystem was integrated into the
58 driver to support more i4b/ISDN specific options. As a consequence it is no
59 longer necessary to add a "options sppp" to your kernel
61 file. For configuration of the i4bsppp driver, either the
63 utility is used or it is configured via
69 In case an IP packet for a remote side arrives in the driver and no
70 connection is established yet, the driver communicates with the
72 daemon to establish a connection.
74 The driver has support for interfacing to the
