Abstract: There is disclosed apparatus for routing signals between at least one PCB within a test head and a socket card assembly. In an embodiment, the apparatus may include at least one flexible circuit electrically connecting first and second sides of the PCB and the socket card assembly with one another, and the flexible circuit having a defined shape configured to interface with the socket card assembly and the PCB along substantially perpendicular planes. Methods of routing signals between at least one PCB within a test head and a socket card assembly are disclosed. In one embodiment, a method may include electrically connecting first and second sides of the PCB and the socket card assembly with one another with at least one flexible circuit having a defined shape configured to interface with the socket card assembly and the PCB along substantially perpendicular planes. Other embodiments are also disclosed.

Abstract: A screw-less latching system for securing load boards comprises a frame and a backer plate. The frame includes a loading site for a device under test. The loading site includes a first tee clamp disposed along a first longitudinal axis and a second tee clamp disposed along a second longitudinal axis of the loading site. The loading site further includes a first spring plunger disposed along a first lateral axis of the loading site. The backer plate is configured to attach the device under test. The backer plate includes two lock tabs coupling with the first and second tee clamps. The backer plate further includes a first recess coupling with the first spring plunger.

Abstract: Disclosed are various embodiments of electrical coupling apparatuses and methods. In one embodiment, an electrical coupling apparatus is provided having a first contact array on a card, where the first contact array is located at a first predefined position relative to an insertion edge of the card. The apparatus also includes a flexible printed circuit having a second contact array corresponding to the first contact array, where the second contact array is positioned in alignment with the first contact array. A compliant interposer material is positioned between the first and second contact arrays, the compliant interposer material electrically coupling respective pairs of contacts in the first and second contact arrays. Also, the insertion edge is configured to be inserted into a receptacle, the second contact array being positioned relative to the insertion edge so as to mate with a corresponding contact array in the receptacle when the insertion edge is inserted into the receptacle.

Abstract: A peripheral access module transports voice and data between the common control equipment and the peripheral equipment of a telephone switch. The peripheral access module determines the protocol for transporting the voice and data, and determines the type of medium to effect the transporting. The peripheral access module operatively connects to the peripheral equipment and adaptively reside on a card of the common control equipment.

Abstract: A modular digital telephone system and method featuring a universal telephony shelf adaptable for incremental expansion of legacy telephone switches and as a building block in the construction of new telephony switches. The shelf includes identification and connectors for shelf pairing, and is adapted to receive redundant power supplies, plural line cards, and either a peripheral shelf interface unit or a switch array card which provides both a local shelf interface and three interface units for connection to the peripheral interface units of other shelves. System wide fault displays are provided.
