(2) The coordinator sends a connection to request the
LAN after obtaining LAN information, apply to join the
LAN. The MAC transmits is an acknowledgment to the
nodes in the request state frame layer LAN coordinator, and
it primitives to the upper transmission at the same time
connection request, which identifies the node connection

instructions. According to their specific circumstances, it
decides whether or not to approve the connection in the long
a Response Wait Time symbol period , if approved, then the
coordinator to request device is assigned a short address,
and sent to the node contains a new address and connection
state of the connection response command in non-beacon
mode, and a node must wait for the a Response Wait Time
