In a real installation, TCs and TSs are exchanged between the SCM6/1 and all
the other devices in the transmission system (see the details in the following
paragraphs). In general, TSs and TCs are constituted by dry contacts that are
closed or opened by the generator of the information, and that are energized by
the user of the information.
An example of the set of TCs and TSs exchanged between the SCM6/1 and a
transmitter Is given in figure 4-3.
