THE

ARRICADE

4-22

ATM PVC

To configure your Internet Connection settings, select ATM PVC, then

VC1. Click the VC to set the detailed parameters.

Note: The Barricade can support up to 8 Virtual Circuits (VC's).

Multiple VC's, in general, are only used in the case of Triple Play

(Internet/Voice/Video) services. Example: VC1 = Internet,

VC2 = Voice, VC3 = Video. Unless stated by your ISP, you will

use a single VC. In this case "VC1"should be used.

Parameter Description

VC1 to VC8 Click on the desired VC to configure the connection parameters.

VPI/VCI Displays the Virtual Path Identifier (VPI) and Virtual Circuit

Identifier (VCI) configured for the corresponding VC.

Encapsulation Displays the Encapsulation configured for the corresponding

VC. 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).

Protocol Displays the Protocol configured for the corresponding VC.
