Abstract
Abstract A cable management system which provides routing of wired services between service lines (16) and user lines (18). Each service line enters the cable system at a service termination unit circuit card (22) which also holds a portion of a crosspoint switch matrix (126). Each user line enters the system at a line termination unit circuit card (20). The service termination unit circuit cards are all mounted to connectors (36) on a first side of a centerplane board (24) and the line termination unit circuit cards are mounted to connectors (36) on the other side of the centerplane board. Pins (37) extending through the centerplane board interconnect the connectors so that any service line can be connected to any user line. A system controller card (26) mounted to the centerplane board communicates with the circuit cards via a bus (38) on the centerplane board. Each of the peripheral devices connected to the user lines is provided with an identification device (208) which stores a unique identification code and information characterizing the device. The identification devices are connected to otherwise redundant wires within the cable containing the associated user line. The controller card polls all the identification devices to generate a "map" of all the "assets" of the system.
