NAME

     i4bing - isdn4bsd NetGraph ISDN B-channel interface driver

SYNOPSIS

     device "i4bing" [count]

DESCRIPTION

     The i4bing driver interfaces the FreeBSD NetGraph subsystem with the
     isdn4bsd package.

     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.

     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.
