4.4.1ATM PVC

Enter ATM (Asynchronous Transfer 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

MAC Encapsulated Routing

 

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).
