Patent

CA 2164218

The present invention is a dial in-bound MIU (100) capable of deriving its operating current from a telephone line (120). The MIU is coupled to the telephone line using conventional practices. The MIU has the capacity to initiate data transmission at a predetermined time or upon demand by the customer or the utility company. The MIU includes a microprocessor (u22) which serves as the command processing center for the MIU. The microprocessor also manages all time-dependent functions for the MIU. When the microprocessor determined that data transmission is required, the MIU dials up a central computer using a modem (150) built into the MIU circuitry.

La présente invention a pour objet une UIC (100) intégrée au clavier qui peut tirer son courant de fonctionnement d'une ligne téléphonique (120). L'UIC est couplée à la ligne téléphonique par des procédés conventionnels. L'UIC peut commencer la transmission de données à un moment prédéterminé ou à la demande du client ou de la société d'exploitation du réseau. L'UIC comprend un microprocesseur (u22) qui sert de centre de traitement des instructions pour l'UIC. Le microprocesseur gère également toutes les fonctions de l'UIC dépendant du temps. Lorsque le microprocesseur détermine que la transmission de données doit avoir lieu, l'UIC appelle un ordinateur central à l'aide d'un modem (150) intégré dans le circuit de l'UIC.
