Abstract
A signal is received from a first portion of a power line via a connection to the power line and at least a portion of the signal is converted to a non-electrically conducting signal. The non-electrically conducting signal may be communicated to a non-electrically conductive communication path. In this manner, the non-electrically conducting signal may have properties that do not provide imminent danger from human contact.

58. A device for communicating over a power line having a voltage greater than one thousand volts, the power line forming part of a power distribution system that supplies power to one or more customer premises and wherein each of the one or more customer premises receives power via a low voltage power line that is electrically connected to a distribution transformer, the device comprising:
-
a capacitive coupler configured to couple data to and from the power line; a first modem configured to communicate data over the power line via said coupler; a downstream interface communicatively coupled to said first modem and configured to communicate with one or more utility devices configured to communicate measured utility data; and wherein said coupler, said first modem, and said downstream interface are configured to provide at least part of a data path between the power line and one or more utility devices at one or more customer residences to thereby bypass the distribution transformer. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80)

81. A device for communicating over a power line having a voltage greater than one thousand volts, the power line forming part of a power distribution system that supplies power to a plurality of customer premises and wherein each of the plurality customer premises receives power via a low voltage power line that is electrically connected to a distribution transformer, the system comprising:
-
a capacitive coupler configured to couple data to and from the power line; a first modem configured to communicate data over the power line via said coupler; a second modem configured to communicate with one or more utility devices configured to communicate measured utility data of one or more associated customer premises; a routing device communicatively coupled to said first modem and said second modem; and wherein said coupler, said first modem, and said second modem are configured to provide at least part of a data path between the power line and one or more utility devices associated with one or more customer premises to thereby bypass the distribution transformer. - View Dependent Claims (82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102)

103. A method of communicating over a power line having a voltage greater than one thousand volts, the power line forming part of a power distribution system that supplies power to a plurality of customer premises and wherein each of the plurality customer premises receives power via a low voltage power line that is electrically connected to a distribution transformer, the method comprising:
-
capacitively receiving first data in a first data signal from the power line, wherein the first data signal comprises a wideband signal; demodulating the first data signal to provide a first data packet; matching the first data packet with a destination; modulating one or more carriers with the first data to provide a second data signal; transmitting the second data signal to a first remote utility device disposed at a customer premises; receiving second data from a remote utility device; modulating one or more carriers with the second data to form a third data signal; and capacitively coupling the third data signal to the power line. - View Dependent Claims (104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120)
