Conﬁgure VPI and VCI

Follow the instructions below to conﬁgure the virtual connection.

To conﬁgure the virtual connection, follow these steps:

1.

Enter the values for the

VPI

and

VCI

given to you by your service provider.

2. Select

Enable

from the

Virtual Circuit

pull-down menu to make the connection

active. If you prefer to leave the connection inactive leave this as

Disable

, and

activate it when it is needed.

3.

Choose the type of connection used for the virtual connection and conﬁgure the

settings according to the instructions of your service provider.

4. Click the

Save Settings

button to save the conﬁguration. If you want to establish

the connection now, click the

Connect

button.

VPI

- The Virtual Path Identiﬁer is used with the VCI to deﬁne a dedicated circuit on the ATM network portion of the connection to the Internet and WAN. Most users

will not need to change this setting.

VCI

- The Virtual Channel Identiﬁer is used with the VPI to deﬁne a dedicated circuit on the ATM network portion of the connection to the Internet and WAN. Most

users will not need to change this setting.

Virtual Circuit

- Use this to enable or disable the PVC you are currently conﬁguring. By default, the PVC0 is set to

Enable

.

ATM Trafﬁc Shaping

Settings used for ATM trafﬁc shaping are located beneath the VPI/VCI conﬁguration menu. These settings allow the user to adjust ATM Quality of Service (QoS) or

trafﬁc parameters to suit speciﬁc trafﬁc requirements. For applications or circumstances where packet loss or packet delay is a concern, ATM QoS can be adjusted to

minimize problems. For most accounts, it will not be necessary to change these settings. Altering QoS settings can adversely affect performance of some commonly

used Internet applications.

If you plan to change QoS or trafﬁc parameters, contact your ISP or network services provider for information on what types of adjustment are available or possible

for your account. Your ISP may not support the class of service you want to use.

To adjust ATM QoS parameters, select one of the Service Categories listed here and type in the PCR value in the entry ﬁeld below. For the VBR service category,

an additional parameter (SCR) must also be deﬁned.

UBR

– Unspeciﬁed Bit Rate, this is the default category used for general-purpose Internet trafﬁc where normal levels of packet loss and delay are acceptable. For

some applications or for multiple connection accounts, it may be desirable to specify the PCR.

CBR

– Constant Bit Rate, usually used in circumstances where very low packet loss and very low Cell Delay Variable (CDV) are desirable.

VBR-r

t – Real-time Variable Bit Rate. This models bursty trafﬁc with speciﬁed peak and sustainable rates. Please note that when VBR-rt is speciﬁed, both PCR and

SCR are required (by ATM standards).

VBR-nrt

– Non-real-time Variable Bit Rate, usually used when network trafﬁc is characterized by bursts of packets at variable intervals, and some moderate packet

loss and delay is acceptable. This category is typically used for audio and video applications such as teleconferencing. The network must support QoS Class 2 to

use VBR-nrt.

Depending on which

Service Category

is selected, it will be necessary to change one or more of the following parameters:

PCR

- Peak Cell Rate – The PCR is inversely related to the time interval between ATM cells. It is speciﬁed for all three service categories (UBR, CBR and VBR) in Kbps.

SCR

- Sustainable Cell Rate – The SCR is deﬁned for the VBR service category. This is the rate that can be sustained for “bursty”, on-off trafﬁc sources. It is a function

of Maximum Burst Size (

MBS

) and the time interval (between cells).

Wireless Setup

The Router’s basic wireless and wireless network security settings are conﬁgured in the

Wireless Settings

conﬁguration menu. To access this menu, click on the

Wireless Setup

link in the left panel of the

Setup

menu directory. It is the ﬁrst page that appears when you successfully access the Web manager.

The

Wireless Settings

menu presents three options for conﬁguration. Choose from

one of the three following conﬁguration procedures:

1. Launch the

Wireless Network Setup Wizard

to conﬁgure the Network Name

(SSID) and WPA wireless network security. Click the

Wireless Network Setup

Wizard

button to begin. This option is recommended for most users.

Note

: The Wireless Network Setup Wizard uses WPA wireless network

security. If you wish to conﬁgure WEP wireless network security, use Manual

Wireless Network Setup.

2. Use the

WPS (Wi-Fi Protected Setup) Wizard

to add individual wireless clients.

Click the

Add Wireless Device with WPS

button to use begin conﬁguration

with WPS.

Note

: Wireless clients added to using this method must support WPS.

3.

Conﬁgure the SSID, channel and wireless network security settings manually.

Click the

Manual Wireless Network Setup

button to go to the general wireless

network settings menu.

Wireless Network Setup Wizard

Click on the

Wireless Network Setup Wizard

button in the

Wireless Settings

menu to begin conﬁguration of basic wireless network settings and WPA wireless

network security.

In the ﬁrst Wireless Setup Wizard menu, enter the name used for the wireless

network in the

Network Name (SSID)

entry ﬁeld. The

SSID

or Service Set Identiﬁer

is the name used for the wireless network or a part of the wireless network. Wireless

clients must use this SSID in order to access the wireless network and use the

Router.

To conﬁgure WPA wireless network security, the Wizard menu offers two options. The

easiest and recommended method will conﬁgure WPA network key automatically.

To automatically conﬁgure WPA network security, choose the option

Automatically

assign a network key

and click on the

conﬁguration. The new

Pre-Shared Key

and WPA wireless security settings are

displayed in the

menu. For later reference, be sure to print this

menu; or copy the new automatically created Pre-Shared Key and paste it into a

document to be saved. Click on the

Save

button to save the new wireless settings.

The automatically created pre-shared key is randomly generated.

Note

: For future reference, print out the
