WAN Section

This section allows to specify the WAN connection parameters and the ATM

PVC settings provided by your Internet Services Provider (ISP).

The

Figure 1 shows different kind of connections used by the Router to connect

to the network.

FIGURE 1

WAN Main screen

The Router supports the following two modes:

•

ATM PVC

•

Clone MAC

WAN >> ATM PVC

By selecting the first mode (

ATM PVC

), it is necessary to enter the virtual con-

nection parameters (see

Figure 2).

DESCRIPTION

VC1-VC8

Click on the desired VC to set the values for the connection. In most

cases a single VC will be provided. For single VC use VC1

VPI/VCI

It displays Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI)

configured for corresponding VC

Encapsulation

It displays Encapsulation configured for corresponding VC

•

VC-MUX: Point-to-Point Protocol over ATM Virtual Circuit Multi-

plexer (null encapsulation) allows only one protocol running per vir-

tual 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

It displays protocols configured for corresponding VC. Configured proto-

cols can be: 1483 Bridging, PPPoA, 1483 Routing, PPPoE, MAC En-

capsulated Routing.

1483 BRIDGING

When

1483 Bridging

is selected on ATM Interface, a list of parameters is to be

filled (see

Figure 3). Refer to

Table 2 to get information on parameter meaning

and values. When all fields have been properly filled, do select the

SAVE SET-
