Configuring a Point-to-Point Node
Configure a Point-to-Point Network Interface
Type Enter DD (direct dial) if you always
want to call the same host over a dial
link. If you choose DD the remote host
does not have to be adjacent and other
nodes can be accessed through the
remote host. Enter SD if you want to
call more than one adjacent remote
node over a dial link without
reconfiguring. If you choose SD, no other
remote nodes can be accessed through
the remote host; it is an end point in
the connection. Enter DC if the link is a
leased line, private line, or other
non-switched link.
