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 on the opposed sides of the centerplane board 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. A line test circuit card (50) is mounted to one of the connectors on the first side of the centerplane board. The line test circuit card contains a test unit (54) and a crosspoint switch matrix (146) so that the test unit can be connected to any of the user lines in order to run tests of that user line.
