== Telecommunication Polymorphism ==
The machines can be retrofitted manually to work with other machines that normally would not be very common or wise. In the case of an emergency, however, it can be a life-saver. You can use a multitool to interface with telecommunication machines, which will allow you to modify some of the machines' properties. You can also link together machines with this interface, which is possibly the most important function.

In order to link two machines, access one of them with your multitool. Select [Add Machine] at the bottom of the window to store this machine in the buffer of the multitool. Now access the other machine with the same multitool. The machine previously buffered should still be in the buffer of the multitool. Select [Link] to add the machine currently buffered to the list of machine links of the machine currently accessed. This will establish a link between these two machines. (Note that it is possible to link a machine to itself; this is both harmless and pointless.)

=== Subspace Receiver ===
You can link Subspace Receivers to either Buses or Hubs. If you want to send signals across z-levels, you'll need to link it to a hub that's linked to a relay. Otherwise, you can link it to a bus with no loss of functionality.

=== Bus Mainframes ===
While it is technically optional, if you do not link the bus to a Processor Unit, signals' readability will suffer substantially. Linking to a processor is all but necessary.

You can link Bus Mainframes to the hub or directly to ''Subspace Broadcasters'' if you are unable to link to a functional server. Note that if you link directly to the broadcaster, relays connected to the hub won't be used and other z-levels won't receive the signal.  Otherwise, this will not have much of an effect besides a very minuscule performance decrease.

=== Processor Units ===
According to the code, you can link Processor Units to ''Telecommunication Servers'' instead of Bus Mainframes. This will naturally have a significant performance cost. However, since processors must be linked to buses to receive the information in the first place, using this feature isn't actually possible.

=== Telecommunication Relay ===
Relays must be connected to a Hub in order to add information to the signal about the Z level it is in, and which will broadcast in. It cannot be linked to any other machine usefully.

=== Telecommunication Hub ===
This machine is essential when creating relays that allow you to send and receive signals to and from different Z-levels. It is ordinarily connected to relays, receivers, buses, servers, and broadcasters. When it receives information from relays it sends it to linked receivers, and those receivers send it to the hub, and then the hub sends it to all linked buses. If the hub receives information from a machine that isn't a receiver (either the bus or a server), it assumes it's ready-to-transmit data and then sends it to all linked relays and broadcasters. 

=== Telecommunication Servers ===
These can either be linked directly to a broadcaster or to a hub. They must be linked to the hub in order to broadcast information to relays on other z-levels, but otherwise there's no benefit. Servers are only needed to store logs and maintain sane bookkeeping.

=== Subspace Broadcasters === 
Broadcasters are the output, there is nothing you can do with these in terms of polymorphism.
