ABSTRACT:
A virtual tributary (VT) or tributary unit (TU) of a selected size is multiplexed with transport overhead and further multiplexed with framing bandwidth of an underlying transport technology for providing a virtual tributary/tributary unit plus transport link overhead plus transport framing for transport on a selected transport technology. This enables individual virtual tributaries/tributary units to be transported with defined line overhead and using existing transport technology framing. Several examples of underlying transport technologies used in conjunction with selected transport formats for VT-1.5 and VT-2 superframes are shown.
