Abstract: An automated meter reading system and communications network. The system comprises a multi-tiered network for obtaining information from utility meters and communicating the information to a central database. A plurality of terminal units are each operatively connected to a utility meter to sense operational data of the utility meter and transmit the data through the network when polled. A plurality of primary units are each operatively connected to a utility meter to sense operational data of the utility meter and transmit the data through the network. The primary units also request data from one or more of the terminal units by polling the terminal units, and transmit that data through the network. Data collection units receive data from the primary units and transmit the data to a central host computer. The network is configurable so that status information or requests can be transmitted from the terminal units to the host computer or from the host computer to any of the terminal units.
