Abstract
A physical-layer cross connect (PLCC) includes a system-bus interface; a switching circuit having multiple externally accessible data ports, an internal-only PLCC-controller port, and a data bus that is dynamically configurable among the externally accessible data ports and the internal-only PLCC-controller port; transceivers connected to the externally accessible data ports and to a signal bus; data jacks connected to the transceivers; and a PLCC controller interfaced with the system-bus interface, the data bus, the signal bus, and the internal-only PLCC-controller port and configured to: receive path-configuration commands from a communication-path-management controller and responsively configure connections on the data bus; receive mirrored copies of inbound data by selectively configuring connections on the data bus between the internal-only PLCC-controller port and the various externally accessible data ports; analyze the mirrored copies of inbound data to determine at least one informational characteristic; and report the determined informational characteristic(s) to the communication-path-management controller.
