ATM

Asynchronous transfer mode (ATM) is a fixed-length, cell-based, packet-switching technology that transmits data across an ATM network. You can reach the ATM network through a direct connection such as digital subscriber line (DSL) or cable modem, or through an ATM on-demand connection. The Routing and Remote Access service supports Point-to-Point Protocol (PPP) connections over switched virtual circuit (SVC) or permanent virtual circuit (PVC) ATM connections.

PPP connections over ATM require an ATM adapter with the appropriate support for the physical connection to the ATM network. Once installed, the ATM adapter appears as a dial-up device. For more information, see Devices and ports.

For more information on ATM and ATM support in the Windows Server 2003 family, see Windows ATM Services.
