ABSTRACT:
A method for the transmission of data in a synchronous digital hierarchy (SDH) network comprising the steps of transmitting to a node of the network a form of data signal from outside the network, converting the signal into a to a virtually concatenated information structure and transporting the signal through the network in the virtually concatenated information structure; means for carrying out the method and tributary cards arranged and configured to process signals received in contiguously concatenated form to convert them into virtually concatenated form for transfer across the network; thus providing for data transmitted in high-bandwidth, contiguously concatenated signals (ie VC-4-4c) to be transported across a SDH network, not itself capable of carrying contiguously concatenated signals.
