As a result, the core insulation achieves a higher capacity, which in turn gives the cable the higher voltage class. The motor cable with its voltage class of 600/1000V is required if the motor speed is controlled by a frequency converter and voltage peaks occur due to the pulse width modulation. To tap the China traffic, the Americans further laid a cable from Manila to Shanghai. Like the dispute with Time Warner Cable and Hearst Television, these channels were replaced with other cable offerings. Digital signal processing can receive and interpret input from multiple sensors simultaneously (such as the altimeters and the pitot tubes) and adjust the controls in real time. Bosch published several versions of the CAN specification. ISO 11898-3:2006 specifies low-speed, fault-tolerant, medium-dependent interface for setting up an interchange of digital information between electronic control units of road vehicles equipped with the CAN at transmission rates above 40 kbit/s up to 125 kbit/s. The first slot is reserved for a "Start Code" that specifies the type of data in the packet. Concorde was the first production fly-by-wire aircraft with analogue control. In addition, most of the early digital fly-by-wire aircraft also had an analog electrical, mechanical, or hydraulic back-up flight control system.

The Space Shuttle had, in addition to its redundant set of four digital computers running its primary flight-control software, a fifth back-up computer running a separately developed, reduced-function, software flight-control system - one that could be commanded to take over in the event that a fault ever affected all of the computers in the other four. Data Terminal Ready - Computer tells the modem that it is ready to talk. For example, the computer in flight envelope protection mode can try to prevent the aircraft from being handled dangerously by preventing pilots from exceeding preset limits on the aircraft's flight-control envelope, such as those that prevent stalls and spins, and which limit airspeeds and g forces on the airplane. This also enables military aircraft with relaxed stability. In certain designs with limited relaxed stability in the pitch axis, for example the Boeing 777, the flight control system may allow the aircraft to fly at a more aerodynamically efficient angle of attack than a conventionally stable design.

Airbus and Boeing differ in their approaches to implementing fly-by-wire systems in commercial aircraft. Since the Airbus A320, what is control cable Airbus flight-envelope control systems always retain ultimate flight control when flying under normal law and will not permit the pilots to violate aircraft performance limits unless they choose to fly under alternate law. Boeing airliners, such as the Boeing 777, allow the pilots to completely override the computerised flight-control system, permitting the aircraft to be flown outside of its usual flight-control envelope. Modern airliners also commonly feature computerized Full-Authority Digital Engine Control systems (FADECs) that control their jet engines, air inlets, fuel storage and distribution system, in a similar fashion to the way that FBW controls the flight control surfaces. There was another remarkable feature about this line of cables: it became progressively under British control So long as Egypt was in hands other than our own« Egypt was its weak point. World War II revived the 'cable war' of 1914-1918. In 1939, German-owned cables across the Atlantic were cut once again, and, in 1940, Italian cables to South America and Spain were cut in retaliation for Italian action against two of the five British cables linking Gibraltar and Malta.

Two cabling standards have been developed, one for portable DMX512 cables (ANSI E1.27-1 - 2006) and one for permanent installations (draft standard BSR E1.27-2). DMX512 is a bus network no more than 400 metres (1,300 ft) long, with not more than 32 unit loads (individual devices connected) on a single bus. From the beginning of AppleTalk, users wanted to connect the Macintosh to TCP/IP network environments. However, in the event of multiple failures of redundant computers, the A320 does have a mechanical back-up system for its pitch trim and its rudder, the Airbus A340 has a purely electrical (not electronic) back-up rudder control system and beginning with the A380, all flight-control systems have back-up systems that are purely electrical through the use of a "three-axis Backup Control Module" (BCM). The Boeing 787 and Airbus A350 also incorporate electrically powered backup flight controls which remain operational even in the event of a total loss of hydraulic power. This back-up system served to reduce the risk of total flight-control-system failure ever happening because of a general-purpose flight software fault that had escaped notice in the other four computers.
