Abstract: Methods and apparatus for providing local warning of a low battery condition from an optical network terminal to a device in a customer premises are disclosed. An example optical network terminal is coupled to a power supply having a battery. The power supply sends a data signal to the optical network terminal indicating a condition of the battery. The optical network terminal includes a data port to receive the data signal from the power supply. The optical network terminal has a computer data port. A controller is provided to read the data signal and send a warning signal of the battery condition via the computer port to a device in a customer premises serviced by the power supply.

Abstract: A data mining method and system for determining new relevant data from one or more data sources, the data of the data sources comprising pages of data linked together by links is described. The method comprises the steps of visiting the pages of data and obtaining links from the pages to other pages, processing the links in dependence on a predetermined set of rules to eliminate certain types of links, determining from the remaining links, links that existed on a previous visit to the page, eliminating previously existing links and preparing a report including the remaining links as potentially relevant data.

Abstract: A data classification method, data structure and associated systems are described. A number of hierarchical indices are defined and linked to data stored in a database. Data elements are linked to applicable ones of the indices in dependence on characteristics of the data. The link is with the lowest applicable entry in the respective index.
