Abstract: The present invention relates to communication, in particular to communication involving analogue-like signals that are multiplexed together. There is provided a method of communicating with a plurality of devices, each of which of which provides a signal whose amplitude varies in an analogue fashion, the method including the steps of: temporally interleaving the signals from the devices so as to form a multiplexed signal having a plurality of sequential pulses, which pulses can, in an analogue fashion, each have an amplitude within a continuous range, each pulse originating from a respective device, and each pulse having a plurality of temporal portions; and, forming a synchronisation signal within the multiplexed signal for demultiplexing the multiplexed signal, the synchronisation signal being formed by reducing the amplitude within a temporal portion of at least some of the pulses.

Abstract: Following a transmission comprising a plurality of symbols, an error measurement is generated for each symbol, so that one may distinguish between symbols having a relatively low error and symbols having a relatively high error. A bit rate to be used for subsequent transmission is determined as a function of error measurements of those symbols that have relatively low error and as a function also of the proportion of symbols having a relatively high error, such that the bit rate reduces as the proportion increases. Measurement of the error rate and/or the durations of high and low error conditions may also be used to set other transmission parameters such as error-correcting code and interleaver settings.

Abstract: A digital subscriber loop modem arrangement is arranged to respond to a fault condition so as to provide at least a voice lifeline service over DSL service on a digital subscriber line in which data and voice traffic are transported on a plurality of carriers. On detection of a power loss at the subscriber end of the line, the number of carriers is reduced so as to maintaining transmission only of those carriers transporting the voice traffic. This reduces the power demand which can now be met from the remote end of the line. A method of operating a digital subscriber loop modem arrangement under a fault condition so as to provide at least a voice over DSL service on a digital subscriber line in which data and voice traffic are transported on a plurality of carriers, the method comprising the steps of: replacing the data with random data, disabling those data carriers on which the random data is transported, and maintaining transmission of those carriers transporting the voice traffic.

Abstract: A method of and apparatus for capacity determination in a telecommunications system, in the presence of Gaussian and non-Gaussian noise. The ratio of Gaussian to non-Gaussian noise is determined utilising a statistical metric. Preferably the metric is Kurtosis or the 3rd Cumulant of the Probability Density of the signal at each frequency. The determination of the ratio of Gaussian to non-Gaussian noise enables a more accurate determination of Noise, which in turn allows greater utilisation of actual available capacity in the system.

Abstract: A method, apparatus, and software for providing lifeline service during power failure affecting Customer Premises Equipment (CPE) in a Digital Subscriber Loop (DSL) arranged to carry voice traffic in band rather than on a separate analogue POTS band. The arrangement provides a reduced service, capable of supporting at least one voice call, to operate during such power failure and, where a single call is in progress during power failure, that call may be maintained during the transition from DSL to analogue POTS lifeline service. Where a call is in progress upon power restoration, the lifeline POTS service may be maintained until completion of the call so as not to interrupt a potential lifeline call.
