Abstract
A power meter or other electrical device is provided having two independent and communicatively isolated Ethernet ports. The first Ethernet port is addressable by a first unique identifier and is configured for enabling full access to the power meter via an internal LAN. This enables a LAN operator to remotely access the power meter via the internal LAN for performing metering functions, such as full telemetry, control and programming. The second Ethernet port is addressable by a second unique identifier and is configured for being connected to the Internet. Since the second Ethernet port is communicatively isolated from the first Ethernet port, a user can access the power meter via the Internet, but cannot access the internal LAN by connecting to the power meter via the Internet.

12. A method for communicating with at least one electrical metering device comprising the steps of:
-
providing the at least one electrical metering device with a first Ethernet port having a first unique identifier and a second Ethernet port having a second unique identifier; connecting said first Ethernet port of the at least one electrical metering device to a first network via a first Ethernet port-first network connection; and connecting said second Ethernet port of the at least one electrical metering device to a second network via a second Ethernet port-second network connection, wherein said first and second Ethernet ports are communicatively isolated from each other. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method for communicating with a metering device adapted for monitoring at least one parameter of an electrical utility, comprising:
-
accessing operational functions of the metering device via a first communication port adapted for coupling to a Local Area Network (LAN), said operational functions including programming or re-programming the metering device; and accessing instantaneous or historic information stored in the metering device via a second communication port adapted for coupling to the Internet; and communicatively isolating the first communication port and the second communication port from each other. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)
