An optical signal carrying an arbitrary mix of concatenated and/or non-concatenated data traffic is split and transported across a network space between a start node (18a) and an end node (18b) through a hyper-concatenated connection (26, 28,30) set up through independent pointer processor state machines (12a, 12b). At the start node, the concatenated optical signal is split into two or more hyper-concatenated data streams (44a-44d). If a split occurs at a frame within a concatenated signal, the start node replaces a concatenation indicator (CI) of the frame with a payload pointer (PP) from a first frame of the concatenated signal and inserts a split indicator (SI) in SS bits of the frame overhead. The hyper-concatenated data streams are transported across the network space using respective ones of a plurality of independent channels. At the end node, the hyper-concatenated data streams are recombined to recover the original concatenated signal. Frames containing split indicators are modified to remove the split indicator and to replace the payload pointer with a concatenation indicator. The advantage is an ability to set up hyper-concatenated connections through a network space containing independent pointer processors, such as legacy cross-connects or ADMs (14a). <IMAGE> |
