Once the router joins the PAN, it can communicate with other devices on the PAN and allow new
devices to join to it.

3.1.3. Joining an End Device

When an end device first comes up, it must also locate and join a PAN. End devices follow the
same process as a router to join a PAN. Once the end device has successfully joined a PAN, it can
communicate with other devices on the PAN. However, since end devices cannot route data, they
must always communicate directly with their parent and allow the parent to route data in its
behalf.
