Title: Method and system for testing a transmission line in a non-addressable network for continuity
Inventor: ESTES DANIEL L
IPC: H04B3/46
Filed: 1998-11-03
Abstract: A method and system for testing the continuity of a transmission line (118) in a non-addressable network (116). A method and system in a communications service environment are provided, the environment including an addressable network (110) and a non-addressable network, for testing transmission line continuity in the non-addressable network. In an embodiment, a signal generator connected to a first transmission line (113) in the addressable network generates a signal on the first transmission line. The first transmission line is connected to a second transmission line in the non-addressable network by a bridge (100). The bridge transfers the signal from the first transmission line to the second transmission line. The system also includes a signal receiver (108) connected to the second transmission line for receiving the signal over the second transmission line when the second transmission line is continuous. The receipt of the signal over the second transmission line at the signal receiver indicates that the second transmission line is continuous.

Title: Method for digital data transmission with a variable bandwidth
Inventor: WERNER THOMAS
IPC: H04M11/06
Filed: 1999-01-22
Abstract: The invention provides a method for digital data transmission with a variable bandwidth which can be used in a network which has at least one server 3, a user terminal 6 and a network management system (TMN) 4. In this case, firstly a connection is established between the user terminal 6 and the server 3 via an ADSL connection 12. Bandwidth selection data are then transmitted from the user terminal 6 to the network management system assigned to the server 3. Information data are then transmitted from the server 3 to the user terminal 6 via the ADSL connection 12 and/or in the opposite direction with a bandwidth corresponding to the previously transmitted bandwidth selection data. In this case, the bandwidth selection data may be transmitted in particular via the eoc channel 8 of the ADSL connection 12. The network management system 4 transmits billing data to a billing device 5, assigned to the server 3, in a manner dependent on the previously transmitted bandwidth selection data. The invention thus enables the operator of ADSL systems to have diverse possibilities for service differentiation, resulting in greater possible exploitation of the market and therefore increased profitability for the operator.

Abstract: A communication terminal decreases its transmission power only when it receives controls to decrease the transmission power from all the base stations in communicating with the terminal, and does not decrease its transmission power otherwise. The communication terminal stores therein the past transmission power control information from the base stations in communication. If power increase control is continuous, the terminal follows the transmission power control information from another base station; in contrast if the power increase control is discontinuous, it decreases its transmission power when it is under the controls of transmission power decrease from all the base stations in communication with it and it does not when information on transmission power decrease is not all.
