Check “Enable Automatic Time Server Maintenance” to automatically maintain the Belgacom b-

box’s system time by synchronizing with a public time server over the Internet. Then configure

two different time servers by selecting the options in the Primary Server and Secondary Server

fields.

Password Settings

Use this page to restrict access based on a password. By default, there is no password.

For security you should assign one before exposing the Belgacom b-box to the Internet.

Passwords can contain from 3 to12 alphanumeric characters and are not case sensitive.

Note:

If your password is lost, or you cannot gain access to the user interface, press the reset

button (colored blue) on the rear panel (holding it down for at least five seconds) to

restore the factory defaults. (By default there is no password.)

Enter a maximum Idle Time Out (in minutes) to define a maximum period of time an inactive login

session will be maintained. If the connection is inactive for longer than the maximum idle time, it

will be logged out, and you will have to login to the web management system again. (Default: 10

minutes)

Remote Management

By default, management access is only available to users on your local network. However,

you can also manage the Belgacom b-box from a remote host by entering the IP address of

a remote computer on this screen. Check the Enabled check box, and enter the IP address

of the Host Address and click “SAVE SETTINGS.”

31

Note:

If you check “Enabled” and specify an IP address of 0.0.0.0, any host can manage the

Belgacom b-box.

For remote management via WAN IP address you need to connect using port 8080. Simply enter

WAN IP address followed by :8080 in the address field of your web browser, for example,

212.120.68.20:8080.

DNS

32

Domain Name Servers are used to map a domain name (e.g., www.somesite.com) to the

equivalent numerical IP address (e.g., 64.147.25.20). Your ISP should provide the IP address of

one or more Domain Name Servers. Enter those addresses on this page.

WAN

Specify the WAN connection parameters provided by your Internet Service Provider

(ISP).

The Belgacom b-box can be connected to your ISP in one of the following ways:

ATM PVC

The Belgacom b-box uses ATM as its WAN interface. Click on each ATM VC for WAN

configuration.

See the table below for a description of the parameters.

Parameter Description

Description Click on the VC to set the values for the connection.

VPI/VCI Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI).

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).

33

Protocol Protocol used for the connection.

ATM Interface

Clicking on the ATM VC brings up the following screen. The Belgacom b-box uses ATM as

its WAN interface. Protocols including 1483 Routing, 1483 Bridging, MAC Encapsulated

Routing (MER), PPPoA and PPPoE with LLC-SNAP and VC-Mux encapsulations are

supported for each ATM PVC.

When you have finished entering your connection parameters, click “SAVE SETINGS.” You can

verify that you have established an ADSL connection by clicking Status at the bottom of the left-

hand menu. See “Status” on page 4-86.

See the table below for a description of the parameters.

Parameter Description

Protocol

±

Disable: Disables the connection.

±

1483 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 Protocol over ATM is a method of encapsulating data for

transmission to a far point.

±

1483 Routing: 1483 Routing allows a simple, low-cost connection to the Internet via a

standard Ethernet port. The router 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 Belgacom b-box at the head

end).

34

±

PPPoE: Point-to-Point over Ethernet is a common connection method used for xDSL.

±

MAC Encapsulated Routing: If your ADSL service is a Bridged mode service and you

want to share the connection to multiple PC’s, please select MAC Encapsulated Routing.

MER is a protocol that allows you do IP routing with NAT enabled.

VPI/VCI See Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI). Data flows are

broken up into fixed length cells, each of which contains a Virtual Path Identifier (VPI) that

identifies the path between two nodes, and a Virtual Circuit Identifier (VCI) that identifies the

data channel within that virtual path. Each virtual circuit maintains a constant flow of cells

between the two end points. When there is no data to transmit, empty cells are sent. When data

needs to be transmitted, it is immediately inserted into the cell flows.

Parameter Description

Encapsulation Shows the packet encapsulation type.

Packet 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 allows multiple protocols

running over one virtual circuit (using slightly more overhead).

QoS Class ATM QoS classes including CBR, UBR and VBR.

PCR/SCR/MBS QoS Parameters - PCR (Peak Cell Rate), SCR (Sustainable Cell Rate) and MBS

(Maximum Burst Size) are configurable.
