Connections between device connection points are planned in the connection pre-planning phase. Here you create, edit, and manage connections between device connection points, without first placing the devices and / or connections on a page. In connection pre-planning, you plan a connection between a device source and a device target. You can also plan cables that have not yet been placed on a page.
