  • Patent number: 7953073
    Abstract: A communications module including an electrical interface for operatively connecting the communications module to an electric device is disclosed. The electric interface enables data communication between the communications module and the electric device in either a serial mode or parallel mode. The communications module includes: one or more electrical connectors arranged in the electric interface, a Dual Port RAM is connected to the electrical interface for providing parallel transfer of data through the electrical interface, and a control unit connected to at least one of the one or more electrical connectors, wherein the control unit is adapted to determine the value of one or more signals applied on the at least one of the one or more electrical connectors and enable either serial or parallel data communication through the electrical interface depending on the value of the one or more signals.

  • Patent number: 7792092
    Abstract: The invention is concerned with transmission of speech information over mixed networks, particularly over a segment using packet transmission in an otherwise circuit switched data transmission network. According to the invention, PCM transmission lines are connected with a packet based network such as an IP network in such a way, that data from one or more channels of a first PCM transmission line is collected in the payload part of a data packet. Further, the destination address of the data packet is constructed in such a way, that the packet network entity being connected to the second PCM transmission line can determine based on the destination address of the packet, to which channel or channels of the second PCM transmission line the data should be transmitted.

  • Patent number: 7636355
    Abstract: An arrangement of a network element, which routes communication traffic among different types of communication networks, includes a central processing unit configured to perform routing operations on the basis of a communication protocol, which forms a stack. Also, the arrangement of the network element includes devices configured to handle signal processing related issues and communicating with the central processing unit. The communication protocol stack is divided into a first stack situated in the central processing unit, which performs the routing operations of protocols in the first stack, and into a second stack, each device that handles signal processing related issues performing the operations of protocols in the second stack.

  • Patent number: 7304962
    Abstract: The present invention proposes a method of providing information of the echo path of a speech connection in a Packet Data Network, said method comprising the steps of requesting delay information by means for triggering echo removal, said delay information being obtained by signaling a non-speech measurement data unit to said Packet Data Network by an echo estimation means, and measuring the delay of the echo of said measurement data unit by said echo estimation means; replying the echo delay of said measurement data unit from said echo estimation means; generating delay information including at least said echo delay of said measurement data unit; and adjusting a shift register being related to an echo removing device by the use of said delay information such that the performance of said echo removing device is optimized in view of its echo removing capability.
