ABSTRACT:
A digital cross-connect switching system that has a single-stage architecture, a scalable bandwidth, and reduced connection memory storage requirements. The scalable bandwidth digital cross-connect switching system includes a plurality of digital cross-connect building blocks. Each digital cross-connect building block includes at least one cross-connect having a plurality of input ports and a plurality of output ports, at least one connection memory communicatively coupled to the cross-connect, and at least one OR gate. Bandwidth is scaled in the digital cross-connect switching system by interconnecting predetermined numbers of the digital cross-connect building blocks. In general, the size of the digital cross-connect switching system increases as the square of the bandwidth requirement.
