This is the actual network address used for calls routed beyond this node, employing wildcard matching with the * character and treated as ignored entirely when left blank; it's the current, supported replacement for the deprecated cdx6500RoutSVCAddress. An admin only needs a route selection entry here for calls destined outside this node, since calls to local resources like a PAD port or the node's own control port don't require one. For example, setting this to 'BSC*' would match any destination address starting with BSC using the wildcard, routing all such calls per this entry's destination and priority slots.
