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 ( ) having at least one input port ( ), to which an input buffer ( ) is connected for receiving TDM-channels in TDM-frames, and having at least one transmitting buffer ( ). A second device board includes a transmitting section ( ) having a receiving buffer ( ) for every other device board, at least one output port ( ) and at least one output buffer ( ) 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. The transport module is received in a corresponding receiving buffer in the transmitting section and all TDM-channels in all receiving buffers to be sent in a frame via an output port are copied to the output buffer corresponding to said port.
