Synchronous Digital Hierarchy (SDH) customers require complex connections, and cross-connect manufacturers attempt to design switching architectures and algorithms - referred henceforth as cross-connect systems - that will meet these needs; however, the designs are constrained by physical and economic considerations. Thus, the manufacturers are forced to restrict the capabilities of their designs. Such design decisions impact the customers' abilities to transmit and receive certain combinations of traffic. Simulations may be executed to evaluate the impact of the design compromises on the performance of the SDH digital cross-connect. Realistic SDH traffic, which may be utilized as inputs to these SDH switching simulations, is the desired result of this research. This paper summarizes and analyzes an algorithm that produces such connection requests.
