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, Campbelltown, Bowral, Goulburn, Canberra, Yass, Gundagai, Wagga Wagga, Culcairn, Albury, Wangaratta, Benalla, Euroa, 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. There was a marker stone commemorating the official opening of the cable at 532 Hume Highway, C ... [...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 powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euroa
Euroa is a town in the Shire of Strathbogie in the north-east of Victoria, Australia. At the 2016 census, Euroa's population was 3,275. The name Euroa comes from an Aboriginal word in the old local dialect meaning 'joyful'. History Major T.L. Mitchell camped on the banks of the Seven Creeks at Euroa during his 1836 " Australia Felix" expedition. The Post Office opened on 1 January 1854 in the old town, as the township was settled. Euroa's claim to fame is that the National Bank was robbed by Ned Kelly in 1878. Much of the region's wealth once came from sheep but now it comes from horse studs. The Euroa Magistrates' Court closed on 1 January 1990. Heritage sites Euroa contains a number of heritage-listed sites, including: * 1 Binney Street: National Bank of Australasia Building * 90 Binney Street: Euroa Post Office * 99 Binney Street: Euroa Court House Facilities Euroa is roughly midway between Melbourne and Albury. The area is geographically very flat, as the town ... [...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 for the dialling of trunk calls by telephone subscribers without the assistance from 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 term 'STD call' was once commonly used in the UK, Irel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Menzies
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto.

Coaxial Cable
Coaxial cable, or coax (pronounced ) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric ( 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 electrical signals with low losses. It is used in such applications as telephone trunk lines, broadband internet networking cables, high-speed computer data busses, cable television signals, and connecting radio transmitters and receivers to their antennas. It differs from other shielded cables because the dimensions of the cable and connectors are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line. Coaxial cable was used in the first (1858) and follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Postmaster-General's Department
The Postmaster-General's Department (PMG) was a department of the Australian federal government, established at Federation in 1901, whose responsibilities included the provision of postal and telegraphic services throughout Australia. It was abolished in December 1975 and replaced by the Postal and Telecommunications Department. Two separate legal entities had been established in July 1975 to take over the department's operations: Telecom Australia (colloquially "Telecom"; later became Telstra) and Australia Post.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
