Voc� n�o tem muito com o que concordar e/ou discordar. Segundo o google: (ADSL - Asymmetric Digital Subscriber Line) -- A method for moving data over regular phone lines. An ADSL circuit is much faster than a regular phone connection, and the wires coming into the subscriber's premises are the same (copper) wires used for regular phone service. An ADSL circuit must be configured to connect two specific locations, similar to a leased line. A commonly discussed configuration of ADSL would allow a subscriber to receive data (download) at speeds of up to 1.544 Megabits per second, and to send (upload) data at speeds of 128 kilobits per second. Thus the 'Asymmetric' part of the acronym. Another commonly discussed configuration would be symmetrical: 384 kilobits per second in both directions. In theory ADSL allows download speeds of up to 9 megabits per second and upload speeds of up to 640 kilobits per second. ADSL is often discussed as an alternative to ISDN, allowing higher speeds in cases where the connection is always to the same place. See Also: bit , bps , ISDN (SDSL - Symmetric Digital Subscriber Line) -This technology provides the same bandwidth in both directions, upstream and downstream. That means whether you're uploading or downloading information, you have the same high-quality performance. SDSL provides transmission speeds within a T1/E1 range, of up to 1.5 Mbps at a maximum range of 12,000 to 18,000 feet from a central office, over a single-pair copper wire. This option is ideal for small- and medium-sized businesses that have an equal need to download and upload data over the Internet. Portanto voc� pode ter o que voc� quiser, basta pagar o pre�o. O que provalevmente acontece, � que por falta e/ou baixa procura, as operadoras n�o oferecem o SDSL, ou se o fazem, fazem por um pre�o que � proibitivo. O ADSL foi concebido para ser usado por usu�rios dom�sticos, que realmente fazem muito mais downloads que uploads. Mas por causa do pre�o, v�rias empresas est�o utilizando o ADSL como op��o, mas tem-se que lembrar sempre que o ADSL, em principio, n�o foi feito para isso.
