4. The Instrument Room

Most of the equipment on display here is operational and the sequence of events describing how a message is sent through the cable network to its destination can be demonstrated. 'Regeneration' was the automatic process that enabled messages to be received and transmitted onwards from one cable to another without loss or impairment to the signal nor the need to manually translate and then resend the messages. The instrument room also has examples of other equipment which preceded the automated relay stations, however, including the keyboard perforator and the siphon recorder. The message is finally printed onto paper slip and trimmed and mounted onto the telegram form.
