  • programming the data corresponding to a plurality of subscribers into the database, the data comprising a plurality of parameters for each of the plurality of subscribers;

    selectively defining ones of the plurality of parameters to belong to parameter groups identified by parameter group identifiers;

    generating, by the input controller in response to receiving the message, a request for the data corresponding to one of the plurality of subscribers from the database, the request further indicating a desired one of the parameter groups;

    returning, from the home controller, the desired one of the parameter groups corresponding to the one of the plurality of subscribers, in response to the request; and

    storing the data retrieved in a memory of the input controller for a predetermined time, thereby creating a temporary database.
