Field
Description
LLC
With
LLC
encapsulation, a link control
header is added to the Ethernet packet that
identifies the protocol type (Ethernet). This
allows multiple protocols to be transmitted
over the ATM VC.
VC
With
VC m
ultiplexing, .no link control header
is needed as the ATM VC is assumed to be
carrying a single protocol.
Username
Your user name for the PPPoA access provided by
your ISP. This field is alphanumeric and the
maximum length is 64 characters. It cannot start
with a number.
Password
Your password for the PPPoA access provided by
your ISP. This field is alphanumeric and the
maximum length is 128 characters. It cannot start
with a number.
Idle Timeout
Specifies that the PPPoA connection should
disconnect if the link has no activity detected for
n
seconds. This field is in conjunction with the
On-
Demand
feature and is enabled only when the
On
Demand
checkbox is checked. To ensure that the
link is always active, enter a
0
in this field. You can
also enter a value larger than
10
(secs).
Keep Alive
When the
On Demand
option is not enabled, this
value specifies the time to wait without being
connected to your provider before terminating the
connection. To ensure that the link is always active,
enter a
0
in this field. You can also enter any
positive integer value in this field.
This defines the authentication protocol for your
ISP.
This is set to
Auto
by default.
Auto
The authentication is automatic.
CHAP
Stands for
Challenge Handshake
Authentication Protocol.
Authentication
PAP
Stands for
Password Authentication
Protocol.
MTU
This is the
Maximum Transmission Unit
that the
DSL connection can transmit. It is a negotiated
value that packets no more than
n
bytes can be
sent to the service provider. The PPPoE interface
default is
1492 (max)
and PPPoA is
1500 (max).
The minimum MTU value is
64
.
On-Demand
If selected, this enables on-demand mode.
The
connection disconnects if no activity is detected
after the specified timeout value.
Default
Gateway
If checked, this WAN connection acts as the default
gateway to the Internet.

Check this checkbox to enable PPP connection
debugging facilities.
PPP
Unnumbered
PPP Unnumbered
is a special feature. It enables
the ISP to designate a block of public IP addresses
to the customer where it is statically assigned on
the LAN side. PPP Unnumbered is essentially like a
bridged connection.
LAN
The
LAN
field is associated with the
PPP
Unnumbered
field. The packets need to go through
a specific LAN group when the
PPP Unnumbered
feature is activated.
The
PVC Settings
are not mandatory except for the
VPI
and
VCI
fields.
VPI
The VPI defines the virtual path settings for the
ADSL connection between you and your ISP. The
VPI value entered here must be based on the
information provided by your ISP.
VCI
The VCI (Virtual Channel Identifier) defines the
virtual channel settings for the ADSL connection
between you and your ISP.
The VCI value entered
here must be based on the information provided by
your ISP.
PVC Settings
QoS
This field defines QoS at the ATM layer.
Three
different Quality Of Service options are available in
the iConnect625W:
UBR, CBR and VBR
(refer to

7.2.3
Static Connection Setup
A Static Connection type is used whenever an ISP provides a Static IP address. Your ISP
should provide the information for the Subnet Mask and the Gateway.
Up to three
Domain Name Server
(DNS) addresses can be identified. These servers would enable
you to have access to other web servers using the host name.
To configure
Static
connection, follow the steps provided below.
Step 1
:
To begin, click the
Setup tab
on the top menu. Click the
New Connection
link.
The default
PPPoE Connection Setup
page appears:
Step 2
:
From the
Type
drop-down list, select
Static.
The following page appears:

Step 3
:
Enter a unique name for your
Static
connection in the
Name
field. The name
must not have spaces and cannot begin with numbers.
Step 4:
The
NAT
and
Firewall
checkboxes are checked by default under the
Options
field.
Leave these in the default mode.
Step 5:
Select the
Encapsulation Type
(LLC or VC) by highlighting the appropriate
radio button. The default is set to
LLC
. If you are unsure about the option, leave
the default setting as it is.
Step 6:
In the
IP Addres
s field, enter your assigned IP address based on the
information provided by your ISP.
Step 7:
In the
Mask
field, enter the Subnet Mask based on the information provided by
your ISP.
Step 8:
In the
Default Gateway
field, enter the
Default Gateway
based on the
information provided by your ISP.
Step 9:
In the
DNS1,
DNS2
and
DNS3
fields, enter the Domain Name Services values
based on the information provided by your ISP.
Step 10:
For the static configuration in the
Mode
option, the default mode is set to
Bridged

Routed
connection, if this is applicable.
Step 11:
In the
PVC Settings
section, the
VPI
and
VCI
are defaulted to

and
35
,
respectively. Make the changes in these fields, as provided by your ISP, if
required.
If you need to use the VPI and VCI values in an existing connection, you will need to open
it and edit the settings. It is not possible to have more than one connection using the
same VPI/VCI values.
Step 12:
Select the
QoS
. Leave the default value if you are unsure or if the ISP did not
provide this information. The PCR, SCR, MBS and CDVT fields are enabled /
disabled based depending on the selection for QoS. Your ISP should provide
