ABSTRACT:
The present invention provides systems and methods to effectively combine layer one and layer two cross-connects in a hierarchical fashion. The present invention combines layer one and layer two cross-connects between a layer one (L1) line card and a layer two (L2) line card in a transport and aggregation platform. Advantageously, the present invention provides network operators increased flexibility and capability in transport and aggregation networks. Particularly, transport networks tend to contain only layer one capabilities. The present invention makes the introduction of layer two functionality into transport networks practical because an entire physical connection need not be dedicated to all layer one cross-connects or all layer two cross-connects.
