Abstract
A telemetry device is provided which communicates over a phone line to a central host station. The telemetry device includes a plurality of meter ports. In one embodiment, the host station transmits a data activating signal to the telemetry device. The data activating signal instructs the telemetry device to read consumption information from a designated one of the meter ports. The consumption information is then transmitted back to the host station. In another embodiment, one of a plurality of host stations transmits a data signal to the telemetry device. The data signal instructs the telemetry device as to which one of the plurality of host stations to call to provide an on-demand reading of a meter port.
