17.2 ATM
ATM (Asynchronous Transfer Mode) is a data transmission procedure that was originally
designed for broadband ISDN.
ATM is currently used in high-speed networks. You will need ATM, for example, if you want
high-speed access to the Internet via the integrated ADSL or SHDSL modem.
In an ATM network, different applications such as speech, video and data, can be transmit-
ted side-by-side in the asynchronous time multiplex procedure. Each transmitter is provided
with time sections for transmitting data. With asynchronous transmission, unused time sec-
tions of a transmitter are used by another transmitter.
With ATM, the packet switching procedure is connected-based. A virtual connection is used
for data transmission that negotiates between the transmitter and recipient or is configured
on both sides. This determines the route that the data should take, for example. Multiple
virtual connections can be set up over a single physical interface.
