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 service and line termination unit circuit cards is provided with a unique identification code corresponding to the connector in which it is installed, in addition to 'as built' information characterizing the card. The controller card polls all the service and line termination unit circuit cards to generate a 'map' of all the 'assets' of the system. Further, each line termination unit circuit card provides a predetermined voltage to all of the service termination unit circuit cards. The service termination unit circuit cards respond to the absence of that predetermined voltage from a connector on the second side of the centerplane board by opening all connections to that connector.
