Rui_TNV, I think this is possible, but the events file to create units on all the other additional maps (and among them units that can create teleporters from your starting map to those additional maps) must be massively enlarged. Here you cannot operate with the blanc original extended events file.
Additionally to the secondary maps settings (that was explained to you some posts above), units must be created that can exist on those additional maps, the starting locations for those event created units must be set for each map (the last number in the coordinates signs the map) and among those units there must be units that can perform the construction of teleporters to your starting map and you need at least one of those units on your starting map to construct such a teleporter to each of those additional maps, too.
This said, I never did such a construction using the arrival at AC event. I mostly connected two standard maps (number 6 maps, if remembering well).
