Abstract: A frame enclosure for use with electrical communication devices includes joined front and rear cabinets. Patch connectors are mounted in the front cabinet on a divider wall separating the front cabinet into separately accessible first and second compartments, each accessible through a separate, lockable door. External conductors pass through one side of the front cabinet and are terminated on one side of the electrical connectors in a patch field mounted on the divider wall. Conductors from electrical devices in the rear cabinet are engagable with the opposite end of the connectors in the other front compartment after passing through aligned apertures in the cabinet. Industry standard rack mounts are provided in the front and rear cabinets for mounting the electrical connectors and the electrical components in a vertically extending orientation to minimize overall cabinet depth. The rear cabinet has pivotal doors on opposite ends allowing access to the front and rear ends of each electrical device.

Abstract: A communications cabinet for use with copper/fiberoptic converters has electrical connections between power, copper and fiberoptic conductors and the converters preformed as conductive traces on a printed circuit board mountable in a housing. Electrical connections between power, copper and fiberoptic conductors passing through apertures in the housing and corresponding connections to the converters are made through a patch field formed of connectors mounted in the housing, each receiving terminal connectors on the conductors and converter terminations. Seal members are mounted in the housing adjacent apertures through one wall of the housing for sealingly encompassing the copper, fiberoptic and/or the power conductors passing through the apertures in the housing. The printed circuit board receives the converters in a plug-in mount without separate fasteners. An extension cabinet is fixed to the housing and receives power conductor and cables.

Abstract: A method and apparatus is disclosed for selectively connecting network devices 22, 24 to a local area network 26. The apparatus and methodology of this invention 10, enables the devices 22, 24 to be connected to controllers 12, each of which have an output to a uniquely associated multi-station access units 14 and which allows the devices 22, 24 to be individually and selectively connected to the access unit 14. More particularly, the method and apparatus of the invention includes two computers 18, 12 which use voltage signals to selectively connect devices 22, 24 to access unit 14.
