  #dlight server index is unknown
  Angaza index is X*
    get_dlight_server_latest_token_data -> unit number exists on dlight server?
  unit number exists on dlight server?
    yes? -> dlight latest token index is X minus 1 or None?
    no? -> Raise error require ticket to add unit on dlight side
  dlight latest token index is X minus 1 or None?
    yes? -> dlight_create_token_with_id_x
    no? -> is dlight server index and token value equal to Angaza index and requested value?
