Abstract
Presently disclosed are systems and methods for identifying interconnections among physical-layer cross-connect switches. One embodiment takes the form of a method of discovering external connections among a plurality of interconnected physical-layer cross connects (PLCCs). The method includes maintaining external-link mapping data for the plurality of PLCCs, which each include a plurality of ports. The method further includes determining that a first data sequence that was transmitted outbound via a first port of a first PLCC matches a second data sequence that was received inbound via a second port of the second PLCC, and responsively updating the external-link mapping data to indicate an external connection between the first port of the first PLCC and the second port of the second PLCC.
