Asymmetric Digital Subscriber Line

(ADSL) technology provides high-

speed data access over regular

phone lines. ADSL service is able to

co-exist on the same line with your

telephone service.

The ADSL has an unbalanced

connection speed.

It means that you have a connection

where data are received at the

maximum speed of 8Mbps and sent at the maximum speed of 1Mbps. The unbalance allows

to carry out connections with top performance in Internet access or remote access applications.

Asymmetric operation is ideal for home and small office use where files and information are

downloaded more frequently than uploaded.

ADSL modems employ ATM (Asynchronous Transfer Mode) framing. ATM is a protocol that

divides packets into small fixed sized cells for rapid transmission over high-speed networks.

Several different protocols are used over ATM. Michelangelo configuration depends on the

equipment used by your service provider:

Point to Point Protocol Over ATM (PPPoA)

Bridged/Routed Ethernet/IP over ATM (PPPoE)

1.1.
