Technology
Physically, it has two rows of 23 pins, making 46 pins total. Three drawbacks of AMR are that it eliminates one Peripheral Component Interconnect (PCI) slot, it is not plug and play, and it does not allow for hardware accelerated cards (only software-based).
Technologically, it has been superseded by the Advanced Communications Riser (ACR) and Intel's own Communications and Networking Riser (CNR). However, riser technologies in general never really took off. Modems generally remained as PCI cards while audio interfaces were integrated on to motherboards.
Recently motherboard manufacturer ASRock has resurrected this concept, introducing the High Definition Multimedia Riser (HDMR) slot on most of its motherboards. Little information is available, but drivers on the Asrock website indicate the existence of V.92 modem cards for this standard. It is not clear how HDMR differs from AMR, if indeed at all.

Famous quotes containing the word technology:
“The successor to politics will be propaganda. Propaganda, not in the sense of a message or ideology, but as the impact of the whole technology of the times.”
—Marshall McLuhan (1911–1980)
“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)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
