TCP/IP Autocalls

Novell IPX Autocalls

302976-A Rev.00
The bridge starts a connection to a remote bridge when it receives
a TCP/IP ARP request packet for an IP address which has to be
defined in the Autocall Table. Once the connection has been set
up, the ARP packet will be sent.
Normally the destination responds with its MAC address which is
returned to the ARP originator, who does not know that a dial-up
connection has been made to carry out the request. If the address
has already been resolved, but the ISDN line has been dropped
(for example, if there was not traffic for 2 minutes), a subsequent
IP packet will make the line active again.
To set this up, add an entry to the ISDN Autocall table of the
Marlin Bridge for an IP address (specific host destination), an IP
subnet (group of hosts), or an inverse subnet (i.e. any host which
is not in the local subnet). Each entry should contain the IP
address of the destination and the ISDN number (or name ) of the
destination Marlin Bridge. The subnet mask is specified by
adding the number of significant bits to the IP address:
1.1.1.78/32 is a specific host 1.1.1.78
1.1.1.0/24 is a class 'C; subnet 1.1.1.
1.0.0.0./8 is a class 'A' subnet 1
!1.1.0.0./16 is for any address not in class 'B' subnet 1.1
Allows ISDN-only connected IPX network devices to
communicate. This is most useful for remote client workstations
wanting access to central site LAN-based servers on a part-time
basis, but any IPX-based server networks can be linked in this
way.
