This switchboard was manufactured by the Bell Telephone Co. of Canada in Montreal some time between 1886 and 1896, making it one of the oldest surviving switchboards made in this country. It represents the beginning of telephone equipment production in Canada and the key role that telephone operators (generally women) quickly assumed in the efficient functioning of telephone networks. Le standard a été fabrique à Montréal par Bell Téléphone Co. du Canada entre 1886 et 1896. Il est des plus vieux standards aillant survécu au pays. Il représente le tout début de la production de technologie en téléphonie et à jouer un rôle essentiel pour les prépose au téléphone (Très souvent des femmes) ont la tâche de diriger le réseau téléphonique.
Function
Provide a telephone operator with facilities to connect the lines of telephone subscribers on demand and to send and receive signals in support of this. Permet à un prépose au téléphone de connecter les lignes des personnes abonnées et de pouvoir envoyer et recevoir des signaux pour appuyer ces tâches.
Technical
In 1880 Western Electric introduced the Standard board, whose design would set the pattern for decades. The Standard board consists of an array of jacks, each of which is the terminus of a subscriber line. Connections between jacks are made by plugging in patch cords. Above the jack field are annunciator drops, each again connected to a subscriber line. These signal the operator when a subscriber wishes to place a call. All signalling, either by the subscriber or the operator, is accomplished by cranking a magneto, which produces a burst of alternating current capable of tripping a drop and ringing a bell. En 1880 la compagnie Western Electric a introduit la technologie du standard qui a influencé la téléphonie pour les générations qui suivent. Le standard utilise des Jack et fiche pour jumeler des lignes de plusieurs abonnes. L'appelle est émiée par une fiche de connexion quand les annonciateurs sonnent et indiquent à un prépose au téléphone de changer les Jack et fiche aux abonnes désirées. Quand les Jack et fiche sont changées le préposé au téléphone utilisent une manivelle pour produire un courant alternatif à l'aide d'une magnéto. Le courant alternatif enjambe un interrupteur et sonne une cloche qui alerte une abonné de répondre au téléphone.
