Die Systemzuverlässigkeit sollte als Ganzes betrachtet werden, wobei jeder Aspekt des Systemdesigns berücksichtigt werden muss. Besonders anfällige Bereiche sind Datenverbindungen zwischen Schlüsselkomponenten eines Systems. Diese Datenverbindungen können in Form von Rückwandleitungen, Punkt-zu-Punkt-Kabelverbindungen und Punkt-zu-Mehrpunkt-Datenverbindungen über Kupferleitungen vorliegen. Dies sind nur einige Beispiele für die Arten von Datenverbindungen, die in Kommunikationssystemen verwendet werden. Oft identifizieren Entwickler kritische Datenpfade in ihren Systemen, für die redundante Leitungen benötigt werden, falls die Hauptdatenleitung nicht mehr funktionsfähig ist. Diese ausfallsicheren Leitungen ermöglichen es den Entwicklern, die Firmware des Systems so vorzuprogrammieren, dass sie bei einer nicht mehr funktionsfähigen primären Datenleitung auf redundante Leitungen umschaltet. Würden die Entwickler für die Realisierung der primären Datenleitung die parallele Nachrichtenübertragung nutzen, wäre zur Schaffung einer redundanten Sicherheitsverbindung dieselbe Anzahl von Datenverbindungen nötig. Bei der Realisierung einer 2,5-GBit/s-Verbindung mit 32 Datenleitungen (Vollduplex) bei LVTT-Nachrichtenübermittlung müssen zusätzlich zu den Takt- und Steuersignalen, die möglicherweise benötigt werden, weitere 32 Datenleitungen für die redundante Verbindung realisiert werden. Wenn die Datenverbindung jedoch mittels SerDes erfolgt, muss zum Hinzufügen einer redundanten Verbindung lediglich eine weitere SerDes-Verbindung ergänzt werden, die (bei Vollduplexbetrieb) nur zwei weitere differenzielle Leitungen benötigt.

STMicroelectronics Inc. surged to the No.-3 ranking in 2007, up from fifth in 2006, due to a 14.4 percent rise in revenue, according to the rankings.

Phoenixville, Pa. — SEH has introduced the PS56 print server, a new WLAN interface card, for connecting HP printers to wireless LANs supporting WPA and WPA2 encryption standards. The PS56 is an IPv6-enabled print server connecting all HP output devices that have an EIO port to a wireless 54-Mbit network (802.11g), using the highly-secure WPA and WPA2 WLAN encryption standards.

    Instrumentation is being embedded in chips, on circuit boards and in systems for design validation, test and debug. A new standard–IEEE P1687 Internal JTAG (IJTAG)–is currently being developed to control, manage, schedule, analyze and access the instrumentation that is being embedded at the core level of chips. The IJTAG standard will rely on the boundary-scan embedded infrastructure in chips and on boards.
