Abstract
A communication network system includes a solid-state meter, an optical line terminal (“OLT”) based device, and a meter network management device. In one embodiment, the solid-state meter, which can be an electricity meter or a gas meter, provides a measurement, and has a serial communication interface. The OLT based device transfers the information between network devices via a communication network. The meter network management device, which may be an optical network terminal (“ONT”), is capable of communicating with the solid-state meter using the serial communication interface via an RS-232 port.

10. A method for reading a meter, comprising:
-
reading a load measurement by the meter according to a predefined measurement schedule; converting the load measurement at the meter to serial binary single-ended data representing an output of the load measurement; forwarding the serial binary single-ended data from the meter to an optical network terminal (“
ONT”
) via a serial connection cable connected between the meter and the ONT;activating a converter in the ONT to convert the serial binary single-ended data representing the load measurement to optical data; and transmitting the output of the load measurement to an optical line terminal (“
OLT”
) based device via a communications network, wherein transmitting the output of the load measurement to an OLT based device includes organizing the output in accordance with ONT management control interface (“
OMCI”
) protocol; and
sending the output to the OLT base device via an optical communications network. - View Dependent Claims (11, 12, 13, 14, 15)
