摘要： The present disclosure generally pertains to systems and methods for cancelling crosstalk in satellite access devices, such as DSLAMs. In one exemplary embodiment, a satellite DSLAM is configured to employ a vectored DSL modulation format, such as vectored VDSL, on both a customer premises (CP) side of the DSLAM and a network side of the DSLAM. For at least one tone communicated by the DSLAM, the DSLAM is configured to maintain a set of coefficients indicative of crosstalk contributions from interferers on both sides of the DSLAM. Based on such coefficients, the DSLAM is configured to cancel crosstalk that couples from one side of the DSLAM to the other.

摘要： A correlation system, such as a correlation optical time domain reflectometer (OTDR) system, transmits a correlation sequence, such as an M-sequence, and measures the returns of the correlation sequence over time. The system correlates the transmitted sequence with the returns to provide correlation measurement values that respectively correspond to different distances from the point of transmission. A correlation error compensation element adjusts each correlation measurement value in order to cancel the contribution of the correlation error floor from the measurements to provide compensated measurement values that are substantially free of the effects of the correlation error floor.

摘要： A communication system adaptively cancels noise and/or interference from signals communicated through a communication channel, such as signals communicated by a telecommunication network. The system, based on a common mode signal of a received signal, generates an estimate of noise or interference within a differential mode signal of the received signal. The system then subtracts the estimate from the differential mode signal in an effort to remove noise from the differential mode signal thereby providing a differential mode signal that is substantially free of the estimated noise or interference.

摘要： A system and method detects within an IP network an offending network device that has been adversely affecting the IP network performance. A discovery protocol frame is propagated to successive network switches and is formed as a field having a query for inquiring within each network switch to which the frame is propagated whether the network switch has a database entry regarding the MAC address and switch port for the offending network device to locate the offending network device. This discovery protocol frame includes a command for any network switch that has the offending network device connected thereto to disable the switch port to which the offending network device is connected or block all data traffic from the MAC address of the offending network device.

摘要： Improved digital driver with transition time control of an output stage output transistor of the digital driver. A predriver circuit has a resistor that forms an RC time constant with a feedback capacitor of the output transistor. The RC time constant is adjusted to control corner resolution of the output transistor in output switching. The RC time constant can be controlled by a digitally-controlled variable capacitor. Additionally, a delay may be introduced in the turning on of the output transistor as compared with the turn off time to reduce simultaneous conduction or shoot-through current.

摘要： An adaptive power supply span powers devices used in telecommunications. It includes a power circuit and control circuit that receives power and sense signals therefrom and provides a control signal thereto and distinguishes between a first network interface load having a constant voltage input power requirement and a second network interface unit load having a constant current input power requirement. A voltage control circuit and current control circuit are interconnected together and connected to the power circuit. A control signal from the voltage control circuit and current control circuit extends to the power circuit. The control circuit maintains a fixed output voltage for constant voltage regulation for the first network interface unit load, if the output current remains below a threshold current. The circuit limits the output current to a regulated value for constant current regulation below the initial maximum value for powering a second network interface unit if the initial output current is greater than the threshold current for a time greater than a threshold time.

摘要： The present disclosure generally pertains to systems and methods for identifying subscriber lines coupled to transceivers of interest. In one exemplary embodiment, an end of a subscriber line is coupled to and terminated by a transceiver of interest. The other end of the subscriber line is coupled to a speaker. The transceiver is then selectively activated and deactivated causing it to transmit its normal frequency spectrum in a predefined pattern. The frequency spectrum includes frequencies audible to humans. Thus, the speaker produces sound capable of being heard by a human, and the sound exhibits periods of noise followed by periods of silence. Indeed, the periods of noise and silence are in a pattern according to the activation/deactivation pattern of the transceiver. Thus, a user can identify the subscriber line that is coupled to the transceiver by identifying which of the lines is coupled to the speaker when the speaker emits noise and silence according to the predefined pattern.

摘要： A query message-based call routing mechanism for a limited access cooperative telecommunication network initially determines whether the called party is commonly located at the same node as the calling party. If not, the calling party node broadcasts a query message to all other nodes in the network to locate the called party. Only the node having local knowledge of the called extension will reply to the query message. Once the node sourcing the query message has received this reply message, it will place a call to the node servicing the called extension.

摘要： The present disclosure generally pertains to automatic wiring systems and methods for generating wiring layouts for integrated circuits. In one exemplary embodiment, a wiring router ensures that the wiring for multiple device segments is matched. That is, the wiring router defines the wiring paths such that the same or substantially similar localized metal patterns exist around each of the device segments. Thus, when an integrated circuit (IC) chip is manufactured according to the wiring layout, the IC chip should be less susceptible to the effects of process variations.
