<p>A system, method, and node for efficiently packing payload of variable or arbitrary frame lengths into a TDM telecommunications system transmission. A transmitting unit transmits a plurality of frames w hose concatenation does not precisely fit into the interval between TDM framing synchronisation patterns to a receiving unit An offset value is determined, which specifies the consequent delay in transmission of a TDM framing synchronization pattern. The offset value is then sent to the receiving unit in conjunction with the TDM framing signal. The receiving unit receives the plurality of frames and the offset value and reconstructs a precise reference instant derived front the offset value By reconstructing the precise interval boundary, the receiving unit remains synchronised with the transmitting unit.</p> |
