The magnitude of the added noise signal is varied, and a function of the signal quality of the data signal is determined in dependence on the added noise signal. Subsequently, a first straight line is approximated to the previously determined function for smaller values of the added noise signal, and a second straight line for larger values of the added noise signal.

| 20080253534 | Method and Device For Checking the Function For Inverting the Polarity on a Subscriber Line Comprising a Plurality of Wires - The invention relates to a method and to a device for testing the function for inverting the polarity on a subscriber connection line (TAL) comprising several wires (a, b), in order to connect at least one subscriber to a subscriber connection line (SLM), which comprises at least one inverting device (RG) and a current measuring device (MG) which is associated with the inverting device (RG). In a first step, the subscriber connection component (SLM) is separated from the inverting device (RG) and forces physical inversion on the wires (a, b) of the subscriber connection line (TAL). In a second step, the inverting function of the inverting device (RG) is activated. In a subsequent third step, the subscriber connection component (SLM) is separated from the device (DC) which forces the physical inversion and is connected to the inverting device (RG). The correct function of inversion is tested during all three steps by measuring the direction of the current flow. | 10-16-2008 |

| 20080247417 | Method and Device for Transmitting Data Via a Transmission Link - The invention relates, inter alia, to a method in which, by reducing the spectral power density in an underfrequency range (UB) of a transmitting/receiving unit, the fact that the underfrequency range (UB) should not be used to send data is indirectly transmitted. This method is particularly suitable for xDSL processes. | 10-09-2008 |
| 20080225833 | Apparatus For Guaranteeing the Availability of Subscribers in Communication Networks Over Network Boundaries - According to prior art, for example, when danger or environmental catastrophe are imminent, the population is warned by information guided via the communication network. This type of warning is however limited when the communication network consists of a plurality of sub-networks and the (warning) information must thus be transmitted over network boundaries to the subscriber The invention solves this problem in that a warning profile is associated with each route/transit switching centre trunk group. The association is carried out during the establishment of the route/transit switching centre trunk group, and is updated as required as changes of the network configuration. Each network transition implicitly thus has one such warning profile. | 09-18-2008 |

| 20080209058 | Method and Communication Device for Transmitting Packet-Oriented Information - A communication network (PKN) fashioned in conformance with at least one transmission protocol is configured such that data packets (BPDU) having first address information (08 address) as protocol-specific address information are processed under the at least one transmission protocol. At least one communication device (PB) is assigned to the communication network (PKN), which communication device is fashioned in such a manner that second address information (00 address) is configured as protocol-specific address information and that data packets (BPDU) having the second address information (00 address) are processed under the at least one transmission protocol. According to the invention, in the case of data packets (PB) incoming at the communication device (PB) and containing first address information (08 address), this is replaced by the second address information (00 address) and the converted data packets (BPDU′) are processed further by the communication device (PB).

| 20080198741 | Method for Providing Alternative Paths as a Rapdid Reaction to the Failure of a Link Between Two Routing Domains - The present disclosure relates to a method for providing substitute routes in rapid response to the failure of a link between two routing domains in a packet-oriented network. After the failure of a link has been identified, substitute routes are provided for routes which have been interrupted by said failure by locally selecting alternative routes and propagating messages along the substitute routes. In order to provide substitute routes, an inter-domain router checks whether the router contains a substitute route. If there is no substitute route, a request message is transmitted to at least one adjacent inter-domain router and the transmission of at least one substitute route is thus requested. If there is a substitute route in the adjacent inter-domain router, the inter-domain router making the enquiries is informed of this in a response message. The present disclosure thus results in the improved provision of substitute routes in response to disruptions in inter-domain routing. | 08-21-2008 |
