Already relatively
early there were public public telephone boxes, which were still rather
simply developed however at the beginning: One removed the receiver and
turned at the crank. Thereupon "Ms of the office" announced itself
and requested to throw a coin into the apparatus. The coin fell now in the
free case into the housing and met at the end of its flight a metal bell. In
the switching center one knew now that the participant had paid.
So
similarly also the apparatus illustrated above functioned. The different
coins fell on different bells, which produced appropriate tones. (only with
long-distance calls.) Thus it looked from the inside:

coin phones are threatened from becoming extinct, map and mobile telephones
make for them life hard.
