Abstract
The last portion of the electrical distribution system is used to provide high-speed communications to residential homes. An aggregation point interfaces a medium voltage power line with a point-of-presence, and a power line bridge enables flow of communications signals between the medium voltage power line and a low voltage power line across a distribution transformer.

10. A system for providing communications over a power distribution system having a medium voltage power line, a plurality of low voltage power lines extending to customer residences, and a first transformer coupling the medium voltage power line to the low voltage power lines, the system comprising:
-
an aggregation device having a first modem communicatively coupled to the medium voltage power line, said aggregation device further including a backhaul interface configured to provide communications via a backhaul link;
a first transformer bypass device having a second modem communicatively coupled to the medium voltage power line for communications with said first modem;
said first transformer bypass device further including a third modem configured to communicate with a plurality of communications devices at customer premises;
said first transformer bypass device further including a router in communication with said second modem and said third modem; and
wherein said first transformer bypass device provides a data path between the medium voltage power line and one or more communications devices at customer premises thereby bypassing the first transformer and wherein voltages of the medium voltage power line are not conducted to the plurality of low voltage power line by said first transformer bypass device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of using a communication system to provide communications between a first and second communication device and a point of presence, the system comprising a bypass device in communication with an aggregation device via a medium voltage power line, the method comprising:
-
at the bypass device;
receiving a first data signal from the first communication device;
demodulating the first data signal to provide first data;
receiving a second data signal from the second communication device;
demodulating the second data signal to provide second data;
prioritizing the first and second data to determine transmission data;
modulating a signal with the transmission data to form a transmission signal; and
transmitting the transmission signal over the medium voltage power line; and
at the aggregation device;
receiving the transmission signal from the medium voltage power line;
demodulating the transmission signal to provide transmitted data; and
transmitting the transmitted data to the point of presence. - View Dependent Claims (32, 33, 34, 35, 36, 37)

-
at the aggregation device;
receiving first data transmitted from the point of presence; and
transmitting the first data over the medium voltage power line in a first data signal;
at the bypass device;
receiving the first data signal;
demodulating the first data signal to provide a first data packet;
determining a destination of the first data packet;
modulating a signal with the first data packet to form a transmission signal; and
transmitting the transmission signal over a low voltage power line to the communication device. - View Dependent Claims (39, 40, 41, 42, 43, 44)
