Your mission, should you choose to accept it, is to learn how to read with your ears. In addition to listening for the telephone, you are being asked to tune your ears to noise frequencies, to anticoding, to the inflated reserves of random indeterminateness—in a word, you are expected to stay open to the static and interference that will occupy these lines. We have attempted to install a switchboard which, vibrating a continuous current of electricity, also replicates the effects of scrambling.
