Abstract: A power line communication system communicating over a medium voltage power line including a VoIP endpoint that transmits voice data and requests to establish a voice connection to a medium voltage (MV) access device is provided. The medium voltage access device may determine a response to the request, allocate voice data packets a higher priority than general data packets, and transmit the data packets over the MV power line according to their priority. The MV access device may provide one or more voice over internet protocol (VoIP) switch functions and, in response to the requests, grant or deny the requests based, for example, on the number of established voice connections.

Abstract: The invention includes a device and a method for testing a communication network that includes an Internet Protocol (VoIP) network. The inventive device includes a user interface for communicating results of a test, a transceiver for allowing the test device to communicate with a telecommunications network, and a digital signal processor for reformatting a communication signal to be tested by the device. The digital signal processor may include at least one coder/decoder that uses various compression protocols including wherein the digital signal processor uses at least one of the following data compression techniques: G.711a-law, G711?-law, G.720, G.723.1, G.726, G.728, G.729, G.729A, and G.729AB2. The transceiver also may be a power line modem. The inventive device may include a processor, random access memory, read only memory, a user interface, and a network interface.

Abstract: A power line communications system that facilitates the provision of differentiated data services is provided. One embodiment of the present invention may include tagging downstream data at an ingress point, such as a point of presence or aggregation point. The tagging of data packets may allow the power line communication network elements such as backhaul points, bypass devices, and repeaters to determine the data type and class of service of each data packet and may allow the network elements to prioritize, queue and transmit the data packets accordingly. Such queuing may employ the use of multiple queues with some queues having different sizes and different weight factors from other queues.

Abstract: A system, device and method for providing communications to a plurality of customer premises via one or more external low voltage power lines is provided. One embodiment of the system includes a power line communication device comprising a first modem configured to communicate over the one or more external low voltage power lines. The system further includes a plurality of wireless interface devices, each located at, and external to, a respective one of the plurality of customer premises. Each wireless interface device may includes a first communication module configured to communicate with the power line communication device via the external low voltage power line; and a second communication module in communication with the first communication module and configured to provide wireless communications for one or more remote devices within the respective customer premises.

Abstract: The repeater of the present invention communicates data signals over power lines. The repeater of one embodiment includes at least one modem that receives a data packet and attempts to decrypt the data packet with a first and/or second encryption key. If the packet is successfully decrypted using the first encryption key, the packet is encrypted using the second encryption and transmitted over the power line. If the packet is successfully decrypted using the second encryption key, the packet is encrypted using the first encryption and transmitted over the power line.
