Abstract: A connector assembly includes a substrate assembly and a receptacle. The substrate assembly includes a first substrate layer having a conductive trace that is accessible for direct electrical interconnection with a first conductor associated with another device. A second substrate layer on the assembly includes an electrical contact for electrical interconnection with a second conductor associated with the other device. The electrical contact on the second substrate layer is disposed such that when the substrate assembly is inserted into the receptacle, the electrical contact is electrically connected with the second conductor, a direct electrical interconnection between the conductive trace and the first conductor is maintained. The arrangement is advantageous in that the connector assembly is capable of transmitting low frequency signals through electrical connections that also serve to maintain a high frequency direct electrical interconnection.

Abstract: A line circuit includes tip and ring voltage amplifiers each having an output resistively connected via tip and ring feed resistors to tip and ring leads in a telephone line. The tip and ring feed resistors have closely matched ohmic values, and are part of a resistance network which also includes first and second voltage dividers. The first voltage divider is connected in series between the output of the tip voltage amplifier and an end of the ring feed resistor remote from the output of the ring voltage amplifier, and includes a first voltage tap. The second voltage divider is connected in series between the output of the ring voltage amplifier and an end of the tip feed resistor remote from the output of the tip voltage amplifier, and includes a second voltage tap. A control circuit includes a differential input connected across the first and second voltage taps. In operation the control circuit causes the tip and ring voltage amplifiers to provide energizing direct current for the telephone line. Tip and ring feedback networks, connected across the respective tip and ring feed resistors, provide feedback signals to the tip and ring voltage amplifiers such that in operation common mode rejection of longitudinally induced a.c. signals on the telephone line is enhanced.

Abstract: A protection arrangement for a telephone subscriber line interface circuit is disclosed. The arrangement is particularly useful for protecting an electronic telephone set from over-voltage and over-current fault conditions. The arrangement provides a FET that operates in saturation mode to connect an office battery to the subscriber line under normal operation. The FET also provides isolation capabilities for protecting the line circuit from an over-current condition on the subscriber line. Over-voltage protection is provided by way of an isolation relay between the line circuit and the subscriber line. Both the FET and isolation relay are operated by a controller that uses timers in the methods of over-voltage and over-current protection that it performs. A further capability of the arrangement is that it resets itself after the fault condition has ended. This feature is particularly useful in the case of fault conditions of short duration.

Abstract: An interconnection device has a substrate that includes a conductive trace having an exposed portion at an edge of the substrate. The exposed portion is tapered toward the edge of the substrate. The exposed portion is provided for direct physical contact with a second conductive trace exposed at an edge of a second substrate. A high frequency direct electrical interconnection is thereby provided that reduces the disadvantageous effects of lateral, longitudinal, and co-planar misalignment between the conductive traces.

Abstract: A network device includes optical modules with both electrical and optical connections facing an end of the optical module configured to be plugged into the network device. The optical modules may extend through a faceplate of the network device or may be retained behind the faceplate. Utilizing optical modules with both electrical and optical connections facing one end of the optical module enables optical fiber management may take place within the network device and independent of the electrical connections. This facilitates replacement of non-functional or obsolete optical modules. The optical modules may be parallel to or approximately parallel to the connector plane when connected to the connector plane.
