Technology Implications
Having a concentrator near a subscriber's telephone results in very low signal degradation before the analog signal is digitized. This provides reliably good voice quality.
Concentrators are often colocated with a Digital Subscriber Line Access Multiplexer (DSLAM). This can provide access to Asymmetric Digital Subscriber Line (ADSL) Internet service for subscribers who are beyond the normal 4 kilometre signaling limit on a copper wire loop. For example, a fiber optic cable might run up to 30 kilometres without a repeater from the telephone exchange to a concentrator site, and local subscriber wire local loops can extend an additional 4 kilometres beyond the concentrator and its DSLAM. With repeaters in the fiber optic cable the distance from the telephone exchange can be extended much farther.

Famous quotes containing the words technology and/or implications:
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
“When it had long since outgrown his purely medical implications and become a world movement which penetrated into every field of science and every domain of the intellect: literature, the history of art, religion and prehistory; mythology, folklore, pedagogy, and what not.”
—Thomas Mann (1875–1955)
