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.
IP Address:
If your IP address is assigned by the ISP each time you
connect, leave this field all zeros. Otherwise, enter your ISP supplied
static IP address here.
Subnet Mask:
If your subnet mask is assigned by the ISP each time
you connect, leave this field all zeros. Otherwise, enter your subnet
mask here.
Connect Type
Sets connection mode to always connected, automatic or manual
connection.
Idle Time: Enter the maximum idle time for the Internet connection.
(in minutes) After this time has been exceeded the connection will be
terminated.
Username:
Enter user name
Password:
Enter password
Confirm Password:
Confirm password
MTU
Leave the Maximum Transmission Unit (MTU) at the default value
(1500) unless you have a particular reason to change it.
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.
Please note that setting the router to bridged mode
disables all advanced features such as VoIP, Firewall, and QoS etc.
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 VoIP Router at the head
end).
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
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.

LAN
Use the LAN menu to configure the LAN IP address and to enable the
DHCP server for dynamic client address allocation.
Parameter Description
LAN IP
IP Address:
The IP address of the VoIP Router.
IP Subnet Mask:
The subnet mask of the VoIP Router.
DHCP Server:
To dynamically assign an IP address to client PCs, enable the DHCP
(Dynamic Host Configuration Protocol) Server.
VLAN Binding
In this section you can assign VLAN’s that you have created in the
VLAN page to certain ports such as LAN port 1, 2, 3 or 4 and the
Clone MAC Address
Clicking on the Clone MAC Address brings up the following screen.
Some ISPs may require that you register your MAC address with
them. If this is the case, the MAC address of the VoIP Router must be
changed manually to the MAC address that you have registered with
your ISP.

VLAN
VLAN Table:
In this table you can click on the ADD VLAN button to add a VLAN
binding or click on EDIT to edit an existing binding, or click on
DELETE to remove a Binding.
VLAN Profile:
This screen will appear if you click on “ADD VLAN” or “EDIT” from the
VLAN page.
WLAN connection. For instance if you have created a VLAN Binding
called “Test”, and you want anything connected to the wireless to be
on that VLAN, then you would change the WLAN setting on this page
from “Default” to the one you created called “Test”.
Parameter Description
DHCP SERVER
DHCP Option 60 Vendor ID:
If you wish you can specify the Name of your DHCP Server (Optional)
Lease Time:
Specify the length of time that the DHCP will assign an IP address to
a computer for.
IP Address Pool
Start IP:
Specify the start IP address of the DHCP pool. Do not include the
gateway address of the VoIP Router in the client address pool. (See
“TCP/IP Configuration”). If you attempt to include the VoIP Router
gateway address (10.1.1.1 by default) in the DHCP pool, an error
dialog box will appear. If you change the pool range, make sure the
first three octets match the gateway’s IP address, i.e. 10.1.1.xxx.
End IP:
Specify the end IP address of the DHCP pool.
Domain Name:
If your network uses a domain name, enter it here. Otherwise, leave
this field blank.

IGMP Querier:
Enable/disable IGMP querying to the VLAN virtual interface. The
option is to control whether to behave as an IGMP querier on the
VLAN bridging network. If IGMP Querier option is disabled, the router
will act as an IP multicast compliant host and send IGMP reports for
its own joined IP multicast groups. No IGMP query messages will be
sent to the specific VLAN.
VLAN Access Control:
In this table you can enable or disable the communication between
the VLAN bindings by ticking (enable) or un-ticking (disable) the
corresponding name in the table.
DHCP Client List
The DHCP Clients List displays the IP Address, Host Name and MAC
Address of each client that has requested an IP address since the
last reboot of the Router. Check the FIX box to have the IP address
and the MAC address linked so that the IP address will always be
assigned as it is on this screen.
Description:
Detail description of the VLAN.
IP Address:
IP address of the VLAN virtual interface on the gateway.
Subnet Mask:
Subnet mask of the VLAN virtual interface.
NAT Domain:
NAT addressing domain to define the NAPT operation of the VLAN
virtual interface. Public means that this VLAN will be visible to the
Internet. Private means NAT is enabled to protect the subnet from
visibility to the Internet.
IGMP Snooping:
Enable/disable the feature to block unnecessary IP multicast
traffic flooding among VLAN ports without the specific multicast
membership. This feature is working based on snooping IGMP
Join/Leave messages among the VLAN ports to update the bridging
forwarding database. IGMP Snooping is extremely useful in saving
bandwidth of low-speed interfaces (ex. WLAN) to improve the network
utilization.

to communicate with each other. This channel must be the same on
the VoIP Router and all of its wireless clients. (Default: 6)
Note:
If you experience poor performance, you may be encountering
interference from another wireless device. Try changing the channel,
as this may eliminate interference and increase performance.
Wireless
The VoIP Router also operates as a wireless access point, allowing
wireless computers to communicate with each other. To configure this
function, you need to enable the wireless function, and you may also
setup the security options if needed.
Wireless Settings
Check Enable or Disable and click “SAVE SETTINGS”. This will turn
the wireless function on or off and enable or disable wireless clients
to connect to the modem.
Channel and SSID
These settings should be left as default unless you have a reason
to change them. You can change the Service Set ID (SSID) and a
common radio channel to be used by the VoIP Router and all of
its wireless clients. Be sure you configure all of its clients to the
same values. The SSID is case-sensitive and can consist of up to
32 alphanumeric characters. Functioning as an access point, the
Gateway can be configured for roaming clients by setting the SSID
and wireless channel.
