Sydney–Melbourne Co-axial Cable
The Sydney–Melbourne co-axial cable was a major telecommunications engineering and construction project in south-eastern Australia in the early 1960s, designed to significantly increase telecommunications transmission capacity between Sydney and Melbourne and other centres, along its route including Canberra. The cable's route was approximately and roughly followed the Hume Highway as it existed at that time. Key points along the route were Sydney, Liverpool, New South Wales, Liverpool, Campbelltown, New South Wales, Campbelltown, Bowral, Goulburn, Canberra, Yass, New South Wales, Yass, Gundagai, Wagga Wagga, Culcairn, Albury, Wangaratta, Benalla, Euroa, Seymour, Victoria, Seymour and Melbourne. It was five years in the making and cost £6.89 million to complete. Its prime purpose was to boost the capacity for telecommunications between the two major cities. The cable was made up of three pairs of tubes, each pair capable of carrying 1,260 simultaneous telephone connections. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Repeater Station, Sydney - Melbourne Coaxial Cable, South Of Jugiong, NSW, May 2012
In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. Some types of repeaters broadcast an identical signal, but alter its method of transmission, for example, on another frequency or baud rate. There are several different types of repeaters; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in an optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal. A broadcast relay station is a repeater used in broadcast radio and television. Overview When an information-bearing signal passes through a communication channel, it is progressively degraded due to loss of power. For example, when a telephone call passes through a wire telephone line, some of the power ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subscriber Trunk Dialling
Subscriber trunk dialling (STD), also known as subscriber toll dialing, is a telephone numbering plan feature and telecommunications technology in the United Kingdom and various Commonwealth countries for the dialling of trunk calls by telephone subscribers without the assistance of switchboard operators. Switching systems to enable automatic dialling of long distance calls by subscribers were introduced in the United Kingdom on 5 December 1958. The system used area codes that were based on the letters in a town's name. A ceremonial first call was made by Queen Elizabeth II from Bristol to Edinburgh. A similar service, built on crossbar equipment, using regionally structured numbering, rather than alphanumeric codes, was experimentally introduced by P&T in Ireland in 1957, with the first services being in Athlone. A full service was rolled out in 1958, initially to exchanges in Cork and then Dublin and its hinterland, and gradually to all areas with automatic exchanges. The ...

Coaxial Cable
Coaxial cable, or coax (pronounced ), is a type of electrical cable consisting of an inner Electrical conductor, conductor surrounded by a concentric conducting Electromagnetic shielding, shield, with the two separated by a dielectric (Insulator (electricity), insulating material); many coaxial cables also have a protective outer sheath or jacket. The term ''coaxial'' refers to the inner conductor and the outer shield sharing a geometric axis. Coaxial cable is a type of transmission line, used to carry high-frequency Signal, electrical signals with low losses. It is used in such applications as telephone trunk lines, Internet access, broadband internet networking cables, high-speed computer bus (computing), data buses, cable television signals, and connecting Transmitter, radio transmitters and Radio receiver, receivers to their Antenna (radio), antennas.
