Library /sys$common/syshlp/ncphelp.hlb SET, NODE, INBOUND node-type  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Required for nodes when the VERIFICATION INBOUND parameter is
 specified for the DDCMP circuit over which the connection is to be
 made. Specifies the type of the node.  The node-type is checked by the
 executor node if the specified node attempts to form a dynamic
 connection with the executor node.  If VERIFICATION INBOUND is not
 specified for the circuit, the INBOUND parameter for the node is
 ignored.  The two possible node-types are:

 ENDNODE    Allows the remote node to be connected only if it is
            configured as an end node.

 ROUTER     Allows the remote node to be connected whether it is
            configured as an end node or a router.
