PHANTOM | 4 |
| 20110051593 | PHANTOM USE IN DSL SYSTEM - Superimposing phantom-mode signals reinforces existing differentially driven DSL downstream signals in a vectored binder of DSLs or reinforces upstream vectored signals in a binder of differentially excited twisted pairs, thus expanding the extra transmission modes of the previous GDSL multi-wire two-sided-excitation invention to the case where coordination can only occur on one-side of the binder. Each pair is treated as a common-mode antenna with respect to earth ground, with some pairs selectively excited at the transformer center tap at the transmit end with respect to a common (earth or chassis) ground reference. Corresponding receivers on other non-excited pairs sense the signals between their center taps and a ground at the opposite ends of the lines to the exciting transmitters. A dual use with hybrid circuits allows the receiving circuit to also have an upstream transmitter and an upstream-sensing receiver on the center tap of the opposite side of an adjacent wire. | 03-03-2011 |
| 20120188865 | Intelligent Patching Systems and Methods Using Phantom Mode Control Signals and Related Communications Connectors - Communications connectors are provided that include a plurality of input ports, a plurality of output ports and a plurality of conductive paths. Each of the conductive paths connects a respective one of the input ports to a respective one of the output ports. The conductive paths are arranged as a plurality of differential pairs of conductive paths that are each configured to carry a differential signal. These connectors further include a control signal input circuit that is configured to capacitively couple a phantom mode control signal onto at least a first and a second of the differential pairs of conductive paths. | 07-26-2012 |
| 20130315048 | TELEPHONE COMMUNICATION SYSTEM AND METHOD OVER LOCAL AREA NETWORK WIRING - A device for enabling a local area network wiring structure to simultaneously carry digital data and analog telephone signals on the same transmission medium. It is particularly applicable to a network in star topology, in which remote data units (e.g. personal computers) are each connected to a hub through a cable comprising at least two pairs of conductors, providing a data communication path in each direction. Modules at each end of the cable provide a phantom path for telephony (voice band) signals between a telephone near the data set and a PBX, through both conductor pairs in a phantom circuit arrangement. All such communication paths function simultaneously and without mutual interference. The modules comprise simple and inexpensive passive circuit components. | 11-28-2013 |
| 20140036653 | COMBINATION DEVICE FOR DSL PHANTOM MODE SIGNALS IN A TELECOMMUNICATION SYSTEM - The combination device includes a first pair of series coupled first and second magnetically coupled coils, to which a first DSL line and a first DSL transmission line are electrically coupled, and a second pair of series coupled first and second magnetically coupled coils, to which a second DSL line and a second DSL transmission line are electrically coupled. A third DSL line is coupled to a first coupling element between the first and the second coils of the first pair, and to a second coupling element between the first and the second coils of the second pair. The combination device is located in a phantom injection module provided with at least five terminals respectively associated to the first DSL line, the second DSL line, the third DSL line, the first DSL transmission line and the second DSL transmission line. | 02-06-2014 |

| 20120026863 | LINK THROUGHPUT ENHANCER - A communication method comprises communicating information on a standardized link compliant with a published standard and communicating information on a private link capable of operation at a throughput higher than maximum throughput of the published standard. The method further comprises monitoring private link performance and increasing information throughput on the private link above the maximum standard throughput by an amount determined by the monitored private link performance. | 02-02-2012 |
| 20120230177 | CONGESTION ABATEMENT IN A NETWORK INTERCONNECT - A method and system for detecting congestion in a network of nodes, abating the network congestion, and identifying the cause of the network congestion is provided. A congestion detection system may comprise a detection system, an abatement system, and a causation system. The detection system monitors the performance of network components such as the network interface controllers and tiles of routers to determine whether the network is congested such that a delay in delivering packets becomes unacceptable. Upon detecting that the network is congested, an abatement system abates the congestion by limiting the rate at which packets are injected into the network from the nodes. Upon detecting that the network is congested, a causation system may identify the job that is executing on a node that is the cause of the network congestion. | 09-13-2012 |
| 20150029832 | TIME DOMAIN SYMBOLS ENCODER AND DECODER - A multidimensional symbol encoder is coupled to a transmitter. Multidimensional symbols are encoded by concatenating two or more partial symbols, wherein individual intervals of up and down sections of the two or more partial symbols are independently controlled as to duration. A multidimensional symbol decoder is coupled to a receiver. Multidimensional symbols are decoded by measuring duration of individual intervals i) that are independently controlled as to duration and ii) that are up and down sections of two or more concatenated partial symbols. | 01-29-2015 |

In one embodiment, heterogeneous domains of nodes share a common control plane via routing and signaling adjacencies established through a network layer control channel. For example, in one embodiment, one or more Internet Protocol (IP) compliant routers, one or more Time Domain Multiplexing (TDM) switches, and one or more Wave Division Multiplexing (WDM) optical cross connects (OXC) run a common instance of an Interior Gateway Protocol (IGP). | 01-15-2009 |
