    摘要: Modems (1) for coupling network-units (40) to devices (50) and comprising receivers (21) for receiving first data from the network-units (40) and transmitters (22) for transmitting second data to the network-units (40), which first data is destined for the devices (50) and which second data originates from the devices (50), are provided with detectors (31) for detecting parameters (p 1 ) of the first data and adjustors (32) for, in response to detection results, adjusting parameters (p 2 ) of the second data, to reduce the chance on network congestion networks (4). Calculators (33) calculate the parameters (p 2 ) of the second data as a function of the parameter (p 1 ) of the first data. The parameter (p 2 ) of the second data is made substantially equal to the parameter (p 1 ) of the first data between a minimum value (b min ) and a maximum value (b max ). The parameters (p 1 ,p 2 ) comprise a bitrate. The network-unit (40) forms part of an access network (4) and the device (50) forms part of a subscriber network (5).

    摘要: In the course of a reflectometry-based qualification procedure of a local loop, which connects customer premises to a central office of a telecommunication network, and in the event of being unable to identify the loop termination associated with the customer premises, a second reflectometry measurement of the local loop is carried out with a different impedance load at the customer premises. Next, the two reflectograms are compared with each other in the time domain in order to delineate among all the reflections those at the customer premises and to determine therefrom the position of the customer premises in the local loop.
