The DATA LINK START command can be received for either automatically or
manually set data links. An error will occur if manually set data links are spec-
ified and yet data link tables do not exist.

The node that receives this command and starts the data links will become
the data link startup node. For automatically set data links, the data links will
be executed according to the settings at the startup node.
