摘要:
A mounting system for the installation of communication termination blocks and communication boxes ("system blocks") on a backplane substantially reduces space requirements for a communications center. The system includes a system block that quickly and removably mounts to a slot in a track. A locking slide either automatically or manually engages the block to hold it securely in place, both mechanically and electrically. Lifting the locking slide releases the block. The block includes an elongated hook that provides lateral support for the block during installation and removal to ensure proper mating of electrical conductors.

A wall or room partition mountable modular rail rack component mounting system. The system includes wall racks shaped for interlocking engagement with each other at their opposite ends and cross stiffener members for placement between the wall rails to hold them in rigid space apart relationship. The wall rails each having a shaped opening at one end and a mating element at the other end thereof. The shaped opening and the mating element interlock with each other. The dimensions and spacings of openings and elements on the wall rails and rail racks for mounting thereon provide for rail racks mounted in vertically aligned closely space relationship that gives uninterrupted rail rack placement.

An EMI/RFI shielded printed circuit board housing of compact design suitable for computer system products (such as, e.g., bridges and repeaters) permits such products to be used on office work surfaces or in a wall-mounted, high density storage system within an office environment. The housing has a five-sided printed-circuit-board container with a back wall defining at least on window for exposing an electrical connector that requires access from the exterior of the container, a removable front cover, a removable trough-shaped rear cover for covering the container back wall and protecting the exposed connector located thereat. The back wall is equipped with support features for permitting the housing to be supported in the high density storage system during use. The container and front cover have a plurality of interior surfaces coated with an EMI/RFI shielding material. In other aspects of the invention, the housing has printed-circuit-board-support features for precisely positioning and supporting the printed-circuit-board within the housing in such a way as to avoid contact between the printed circuit board circuitry and the EMI/RFI-shielding material. In addition, the housing has a connector-access button defining a recessed interior volume into which extends a male electrical connector mounted on the printed circuit board.

A card cage formed of mating, identical halves provides parallel slots for circuit boards carrying snap-on retainer clips with integral pawl-like clasps which lock over ridges on the exterior of the card cage. The clip is released from the cage by squeezing the clasps with one hand before withdrawing the circuit board. Slotted side brackets capture mating ribs on the card cage halves to assemble and mount the card cge to a wiring clost panel.

A method and apparatus for processing electronic data are provided. The method comprises the steps of receiving an out of band data transmission and processing the out of band data transmission to retrieve a Connection Context Information key in substantially real time. Thereafter, an in band data transmission is received and processed employing the encryption key in substantially real time.
摘要:
A faceplate system that removably mounts interchangeable connector mounting inserts. The system uses a faceplate frame having mounting rails with access notches and rectangular connector mounting inserts that have corner legs and spacer walls at their ends. The legs have ledge surfaces slidingly engage the under sides of the mounting rails, and the spacer walls slidingly engage the upper sides of the mounting rails. The legs gain access to the under sides of the rails through the rail notches.
