    Abstract: The measuring method has a voltage (u) applied to the line (1) with periodic measurement of a time derivative of the line current (i) at a defined rate, for provision of a series of voltage values and a corresponding series of differential current values, inserted in a defined set of equations used for calculating the line resistance and line inductance.

    Abstract: The transmission characteristics of the channel are measured and different modulation types are selected adaptively based on the transmission characteristics. At least one of the modulation types is a multi-carrier method in which several modulated carriers are distributed across the frequency range of the channel. The transmission characteristics may be repeatedly measured, and the modulation type automatically selected to match them. The data may be transmitted in messages, each consisting of a preamble and a data part. At least part of the modulation type can be detected from the preamble.

    Abstract: The transmission method involves using interleaving of the data blocks to be transmitted at the transmission side. Coded sub symbol sequences are provided used for modulation of a carrier frequency, with corresponding demodulation and de-interleaving at the reception end. A multi-carrier modulation method is employed for modulation of several channels via parallel sub symbol streams, obtained from the serial data stream to be transmitted.

    Abstract: A device to be configured (DTBC) has elements that are configured in a specific way. Configuration devices reconfigure the device by using received new configuration information. A configuration server (KS) links via a communications network (NW) to a DTBC and has composing devices for writing new configuration information for the DTBC and devices for fixing an up-to-date configuration. An Independent claim is also included for a method for reconfiguring devices in a network of devices and configuration servers.
