摘要： A method for determining the performance of decoding in a telecommunication system having a decoder and a testing apparatus for supplying test data to the decoder includes generating test data having signalling data in a signalling frame format, mapping the test data into two consecutive frames and transmitting the test data from the testing apparatus to the decoder for decoding. The signalling data is decoded from the received two test data frames and transmitted back to the testing apparatus encoded in one frame. The performance of decoding is determined by comparing the transmitted signalling data and the received signalling data in the test apparatus.

摘要： The invention concerns methods for testing a connection either between a central controller of a communication network and a terminal of the network, or between two terminals of the network. In both cases, a terminal sends test pattern data which is to be echoed back by another device over the connection to be tested. In certain circumstances, a terminal may register twice with the central controller, in order to be able to establish the required test connection without disturbing existing connections.
The invention also concerns devices for implementing the methods. The invention can be used in a Hiperlan 2 network.

摘要： The present invention relates to a method for synchronisation of at least one first device or apparatus (6) with at least one second device or apparatus(7), comprising respectively a first (8) and a second (10) counter modulus n, and which are designed to exchange data by means of a galvanic connection. The method according to the invention comprises the following steps:- generation by the second device or apparatus (7) of a clock signal, which acts as a counting basis for the second counter (10);- transmission of this clock signal to the first device or apparatus (8); and- transmission of the data of the second device or apparatus (7) to the first device or apparatus (6), at instants which are separated by at least two cycles of the clock signal, and, each time the second counter (10) is re-initialised, transmission to the first device or apparatus (6) of a synchronisation signal comprising two successive time slots of the clock signal.

摘要： The present invention provides a method and apparatus for improving the performance of splitterless ADSL systems. The present invention provides a uniform technique for adapting an ADSL system to any of these situations. The invention provides a graduated approach to handling anomalies that may be caused by incompatible telephone equipment. One embodiment of the invention attempts to correct anomalous situations without having to interrupt the data communication. If more information is needed, a very brief channel echo measurement is conducted. Only if the problem cannot be resolved at this point is retraining of the modem performed. This approach greatly minimizes interruption of data communication and reduction of bandwidth. Another embodiment of the invention reduces the transmitted signal level to its lowest practical value to minimize interference with telephone equipment. Multiple levels of signal reduction are available, and user input may be obtained to optimize the transmit signal level.

摘要： A data transmission system includes first data terminal equipment (2A), a first modem (1A), a transmission line (3), a second modem (1B) and second data terminal equipment (2B), connected in series. In order to send a control command to the second modem (1B), the first modem (1A) interrupts a path of transmission data from the first data terminal equipment (2A) to the transmission line (3). Then, the first modem (1A) sends the control command to the second modem (1B). When the second modem (1B) detects the control commands, it interrupts a path of receiving data from the transmission line (3) to the second data terminal equipment (2B) to avoid a dead-lock of the data transmission system.

摘要： In packet-based networks (10), it is often desired to test communications between two specific stations (11, 12). This can generally be effected from a first one of the stations (11) by requesting the other station (12) to 'loop-back' a test packet sent from the first station. The first station (11), on receiving back the test packet, can thereby ascertain that not only is communication with the other station (12) possible, but it can also measure the round trip time. However, more complex characteristics of the transmission path between the stations (11, 12) are not ascertainable in this manner. The transmission of a predetermined sequence of packets permits such characteristics to be determined by observing the effect of the network (10) on the sequence considered as a whole. Thus by varying packet size in a sequence, characteristics such as bandwidth, propagation delay, queuing delay and the network's internal packet size can be derived. The use of bursts of packets enables buffer size and re-sequencing characteristics to be determined.
