I4BING(4) BSD Kernel Interfaces Manual I4BING(4)NAMEi4bing — isdn4bsd NetGraph ISDN B-channel interface driver
SYNOPSIS
pseudo-device "i4bing" [count]
DESCRIPTION
The i4bing driver interfaces the DragonFly NetGraph subsystem with the
isdn4bsd package.
The driver just packs packets received from the NetGraph subsystem with‐
out 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
The format of the resulting packet on the B channel is:
(HDLC opening flag) (Packet) (CRC) (HDLC closing flag)
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
isdnd(8) daemon to establish a connection.
