PPPoA LLC. Point to Point Protocol over ATM Logical Link Control allows multiple protocols running over one virtual circuit (slightly more overhead).

1483 Bridged IP LLC (Logical Link Control) provides indirect access to the Internet by flooding, forwarding or filtering bridged protocols through each relevant virtual circuit.

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 the common LAN without compromising performance. Bridged data is encapsulated using the RFC1483 protocol to enable data transport.

1483 Routed IP LLC (Logical Link Control). The barricade looks up the network address for each packet seen on the LAN port. If the address is listed in the routing table as local, it is filtered. If the address is listed under the ADSL port, it is forwarded. Or if the address is not found, then it is automatically forwarded to the default router (i.e., the ADSL router at the head end).

Routing is often contrasted with bridging. The primary difference between the two is that bridging occurs at Layer 2 (the link layer) of the OSI reference model, whereas routing occurs at Layer 3 (the network layer).

1483 Bridged IP VC-Mux. Bridged IP Virtual Circuit Multiplexer (null encapsulation) allows only one protocol running per virtual circuit with less overhead.

1483 Routed IP VC-Mux. Routed IP Virtual Circuit Multiplexer (null encapsulation) allows only one protocol running per virtual circuit with less overhead.

Classical IP over ATM provides a direct replacement for IP links between routers, using IP to ATM address mapping.

Native ATM. Asynchronous Transfer Mode. International standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media.
