Manual telephone switchboard from the thirties of the last century. This typology required the intervention of an operator for its operation by means of the physical connection of the wiring coming from both the external network and the local network. It allowed both incoming and outgoing calls. Connections were made by means of cords, jacks and switching keys. When any of the telephones were picked up, they were identified in the switchboard by the illumination of a specific lamp.
