  • Patent number: 6522669
    Abstract: The present invention relates to a telecommunications system, nodes, device boards and methods in such telecommunications systems, where a node comprises a first device board, which includes a receiving section (25) having at least one input port (29, 31, 33), to which an input buffer (30, 32, 34, 36, 38, 40) is connected for receiving TDM-channels in TDM-frames, and having at least one transmitting buffer (42, 44, 45). A second device board includes a transmitting section (27) having a receiving buffer (48, 50, 51) for every other device board, at least one output port (59, 61, 63) and at least one output buffer (52, 54, 56, 58, 60, 62) for every output port. All TDM-channels received in input buffers intended for the transmitting section are copied to a corresponding transmitting buffer and the content of the transmitting buffer reaches the transmitting section through sending of at least one transport module solely containing all TDM-channels intended for said second device board.

  • Patent number: 6285668
    Abstract: The present invention provides an enhanced method for initiating the selection of frames arriving from multiple base stations in a mobile communications system during a soft handoff condition. The method includes the steps of determining a number of base stations in an active set; receiving and storing a plurality of frames from those base stations in the active set where each frame is associated with a frame sequence. The method further includes the step of initiating selection of one of a plurality of received frames of a sequence upon satisfaction of at least one of a plurality of selection criteria which are based upon the active set and the received frames.
