.Sh NAME

.Nm i4bing
|
|
.Nd isdn4bsd NetGraph ISDN B-channel interface driver
|
|
.Sh SYNOPSIS
|
|
.Cd pseudo-device \&"i4bing\&" Op count
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver interfaces the FreeBSD NetGraph subsystem with the
|
|
isdn4bsd package.
|
|
.Pp
|
|
The driver just packs packets received from the NetGraph subsystem without
|
|
anything appended or prepended into raw HDLC packets on the B channel and
|
|
transfers them to a remote site.
|
|
Packets received from the remote site are queued into the NetGraph
|
|
subsystem
|
|
.Pp
|
|
The format of the resulting packet on the B channel is:
|
|
.Pp
|
|
.Dl (HDLC opening flag) (Packet) (CRC) (HDLC closing flag)
|
|
.Pp
|
|
In the case where a Packet for a remote site arrives in the driver and no
|
|
connection has been established yet, the driver communicates with the
|
|
.Xr isdnd 8
|
|
daemon to establish a connection.
