Abstract
A method and system for interconnecting multiple distributed components in a communication network is provided. The design includes a multiple order cross connection fabric employed to interconnect multiple orders of data with at least one distributed component in the communication network. The design may further include at least one order of path termination and adaptation connection, where the at least one order of path termination and adaptation connection providing an interface between the multiple order cross connection fabric and a data management system. The design may be implemented in a SONET/SDH environment.
Claims41
A cross connect arrangement used to connect a plurality of components in a communication network, comprising:
- a high order termination and adaptation path coupled to transmit and receive high order data and terminate and adapt components of said high order data;
- a low order termination and adaptation path coupled to transmit and receive low order data and terminate and adapt components of said low order data;
- a low order path monitor configured to monitor the low order termination and adaptation path for any absence of appropriate low order data;
- and
- an interconnection with the plurality of components,
- wherein said cross connect arrangement uniformly addresses high order data processing and low order data processing.
