4.4.1 ATM PVC

Enter ATM (Asynchronous Trans fer Mode) function parameters here.

Parameter Description
Protocol • Disable Disables the ATM mode.
• 1483 Bridging Bridging: Bridging is a standardized layer 2 technology. It is typically
used in corporate networks to extend the physical reach of a single
LAN segment and increase the number of stations on a LAN without
compromising performance. Bridged data is encapsulated using the
RFC1483 protocol to enable data transport.
• PPPoA: Point-to-Point over ATM
• 1483 Routing Use 1483 Routing protocol.
• PPPoE Point-to-Point over Ethernet.
MAC Encapsulated
Routing
MAC Encapsulated Routing
VPI / VCI Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI).
Each connection must have a unique pair of VPI/VCI settings.
Encapsulation Specifies how to handle multiple protocols at the ATM transport layer.
• VC-MUX Point-to-Point Protocol over ATM Virtual Circuit Multiplexer (null encapsulation)
allows only one protocol running per virtual circuit with less overhead.
• LLC Point-to-Point Protocol over ATM Logical Link Control (LLC) allows multiple
protocols running over one virtual circuit (using slightly more overhead).
