Abstract: A system of multiple remote meter interfaces (RMI)s and multiple base stations. Each base station concentrates meter reading information received from several RMIs and passes the concentrated information up through a wide area network to a central office. Each RMI may be field installed to communicate with only one base station. Each base station maintains an identification (ID) list having its own base station ID and the RMI IDs for the RMIs with which the base station is enabled to communicate. To install or reinstall a particular RMI without communicating with the central office, a field installer tool operated by a field installation or repair person establishes communication with the base station using the base station ID, then directs the base station to add the RMI ID for the particular RMI to the ID list.
