摘要： A substrate having a conductive plane and a via passing through the conductive plane is provided. The conductive plane contacts the via to electrically interconnect the via and the conductive plane. A gap in the conductive plane separates a surface of the via from the conductive plane to provide an uninterrupted path for electrical current flowing substantially on the surface of the via.

摘要： A system of terminating signals in a telecommunication system is disclosed. In one embodiment a line card comprises functional circuitry, line card connector contacts and a termination resistor. The functional circuitry is used to interface first type ports with second type ports. The line card connector contacts are adapted to be selectively coupled to a backplane of a chassis. The termination resistor is adapted to terminate signal lines when a jumper is coupled across select line card contacts.

摘要： A communication system includes primary and secondary interface cards. A switching circuit allows both of the interface cards to selectively communicate over a medium without inducing reflection. Further, an automatic detection system is provided to allow a management circuit to identify which interface card is coupled as the primary or secondary card.

摘要： A fault warning system controls light sources and a warning signal to provide an indication of fatal and non-fatal faults in a communication system. The circuitry uses a pull-down circuit in electrical communication with light and signal control circuits. The circuit can be operated to activate a first light emitting diode (LED) if an operational status of a monitored circuit is either fatal or non-fatal fault. The circuit can be operated to deactivate a second LED if an operational status of a monitored circuit is fatal, and the second LED remains active if the operational status of the circuit is a non-fatal fault.
摘要翻译：故障预警系统控制光源和警告信号，以提供通信系统中致命和非致命故障的指示。该电路使用与光和信号控制电路进行电气通信的下拉电路。如果所监测的电路的运行状态是致命的或非致命的故障，则该电路可以被操作以激活第一发光二极管（LED）。如果被监控电路的运行状态是致命的，则可以对电路进行操作，以禁用第二个LED，如果电路的运行状态是非致命故障，则第二个LED保持有效。
