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).

CDVT

Cell Delay Variation Tolerance – CDVT is a measure of the cell clumping

phenomenon by which cells are delayed in the network and are

clumped together and arrive at a system at a faster rate than negotiated.

Increasing the CDVT creates greater bucket depth.

MBS

Maximum Burst Size – The MBS is the maximum number of bytes that can

be sent continuously from the source to the destination dropping any

packets. Some ATM providers set the MBS and CDVT very low and adjust

up if problems occur.

ATM VC Settings

ATM VC settings can be configured for all connection types in the WAN configuration window of the

Home

directory.

ATM VC Settings in WAN Settings window

The table below describes the ATM VC settings used to configure a PPPoE or PPPoA connection for an ADSL account.

ATM VC Parameters

Description

PVC

The Router supports using up to eight multiple virtual connections. This

window allows the user to configure WAN settings for all the available

connections (see instructions below on how to set up Multiple Virtual

Connections). Use the PVC drop-down menu to select the connection (Pvc0

to Pvc7) you want to configure. Since most users will use only a single

connection, the default setting

can be used for any changes made to

the WAN settings.

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

As with the PVC setting, this is mainly for use by clients who are configuring

the Router for multiple virtual connections. Use this to enable or disable the

PVC you are currently configuring. By default, the Pvc0 is

and the

remaining PVCs are disabled.

LAN

You can configure the LAN IP address to suit your preference. Many users will find it convenient to use the default

settings together with DHCP service to manage the IP settings for their private network. The IP address of the Router is

the base address used for DHCP. In order to use the Router for DHCP on your LAN, the IP address pool used for DHCP

must be compatible with the IP address of the Router. The IP addresses available in the DHCP IP address pool will

change automatically if you change the IP address of the Router. See the next section for information on DHCP setup.

To access the

Management IP

window, click the

LAN

button in the

Home

directory.

Management IP window

To change the LAN

IP Address

or

Subnet Mask

, type in the desired values and click the

Apply

button. Your web

browser should automatically be redirected to the new IP address. You will asked to login again to the Router’s web

manager.

DHCP

The DHCP server is enabled by default for the Router’s Ethernet LAN interface. DHCP service will supply IP settings

to workstations configured to automatically obtain IP settings that are connected to the Router though the Ethernet port.

When the Router is used for DHCP it becomes the default gateway for DHCP client connected to it. Keep in mind that

if you change the IP address of the Router the range of IP addresses in the pool used for DHCP on the LAN will also be

changed. The IP address pool can be up to 253 IP addresses.
