Patent number: 7831147Abstract: This invention provides a new architecture for a communication system between head-ends and end-users which expands bandwidth and reliability of the communication system. A mux-node receives communication signals from a head-end and forwards the received communication signals to one or more mini-fiber nodes. The connection to the head-end is via a small number of optical fibers and the connections to each of the mini-fiber nodes may be via one or more optical fibers that may provide full duplex communication. The head-end may communicate with the mux-node using digital or digital and analog signals. The mini-fiber nodes may combine the signals received from the head-end with loop-back signals used for local media access control prior to forwarding the signals to the end-users. Upstream data are received by the mini-fiber nodes and transmitted to the mux-node.Type: GrantFiled: November 10, 2008Date of Patent: November 9, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Charles D. Combs, Thomas Edward Darcie, Bhavesh N. Desai, Alan H. Gnauck, Xiaolin Lu, Esteban Sandino, Oleh J. Sniezko, Anthony G. Werner, Sheryl Leigh Woodward

Patent number: 5793590Abstract: A coaxial drop cable safety device is used for cable television, data and telephony applications. The device is used on buried drop cable where 60 Hz powering voltages applied to the drop cable exceed low voltage safety limits and where the drop cable is buried at depths which is less than the minimum required to meet electrical safety codes. Tap end and premise end units are connected to the drop cable. The tap end unit applies a DC voltage to the center conductor of the drop cable. A monitoring circuit in the tap end unit monitors the center conductor DC voltage to a fault from the center conductor to ground along the drop cable. The tap unit will immediately remove the powering voltage In the event of either an open or faulted condition on the center conductor along the entire length of the drop cable.Type: GrantFiled: June 18, 1997Date of Patent: August 11, 1998Assignee: Norscan Instruments, Ltd.Inventors: David E. Vokey, Kenneth N. Sontag, John C. Chamberlain, Oleh J. Sniezko
