Abstract: Methods, techniques, computer program products, apparatus, devices, etc., used in connection with DSL Management Interfaces, significantly improve the management capabilities of a DSL network and/or improve testing relating to DSL equipment and services by permitting better control and operation of a DSL system, including implementation of timestamping for more accurate measurement, monitoring and control of a system. Timestamping further allows customized data collection techniques, where a DSL line can be measured or monitored at intervals whose frequency depends on the line's stability. Moreover, data parameter read and control parameter write operations are presented in conjunction with the use of timestamping. Also, control and operation of a DSL system is enhanced by implementing bit-loading that minimizes, eliminates or otherwise mitigates the amount by which the SNR margin per tone exceeds a maximum SNR margin quantity, where such bit-loading can be selected through an appropriate interface.

Abstract: Described is a method for estimating throughput between first and second communication devices, the method comprising: determining maximum bottleneck throughput of a communication link between the first communication device and a third communication device, wherein the communication link between the first and third communication devices applies a common access network as between a communication link between the first and second communication devices; determining Round Trip Time (RTT) between the first and second communication devices; transmitting packet by applying User Datagram Protocol (UDP) from the third communication device to the first communication device; measuring packet loss rate associated with the transmitted packet by monitoring sequence number of the packet; and translating measured packet loss rate to Transmission Control Protocol (TCP) throughput according to maximum bottleneck throughput and RTT.

Abstract: The transmit power level of a transceiver coupled to a digital subscriber line (DSL) line is reduced from a first transmit power level sufficient for the transceiver to continuously transmit data on the DSL line at a first bit rate to a second transmit power level below the first transmit power level sufficient for the transceiver to continuously transmit data on the DSL line at a second bit rate that is lower than the first bit rate. The reduction in transmit power is limited so that the change does not induce time-varying crosstalk sufficient to destabilize a nearby DSL line. While the transmit power level of the transceiver is reduced to the second transmit power level, the transceiver is suspended from transmitting data on the DSL line for repeated periods of time. Suspending the data transmission is controlled to avoid further time-varying crosstalk sufficient to destabilize the nearby DSL line.

Abstract: An apparatus comprises at least one vectoring engine and a cross-connect coupled to the vectoring engine. The cross-connect is to couple with each of a plurality of customer premises equipment (CPE) devices via a respective DSL loop. An interface is to receive instructions for the cross-connect to couple the vectoring engine to a nonoverlapping subset of the CPE devices via the respective DSL loops. The interface is further to receive instructions for the vectoring engine to apply vectoring to the DSL loop via which to couple one of the CPE devices to the cross-connect.
