Chapter 1 Introduction
Getting to Know the Modem
This section contains a quick description of the Modem’s lights, ports, etc.
The Modem has several indicator lights (LEDs) on its front panel and a series of
ports on its rear panel.
Front Panel
The front panel of the Modem features five lights (LEDs): Power, DSL, Internet,
Ethernet, and USB.
Power Light
The Power light displays the Modem’s current status. If the Power light glows
steadily green, the Modem is receiving power and fully operational. When the
Power light is rapidly flashing, the Modem is initializing. If the Power LED glows
red when the Power cord is connected to a known working outlet power, the
Modem has failed to initialize; contact Technical Support.
DSL Light
When the Modem connects to the DSL service, the DSL light will glow solid
green. If the DSL light blinks rapidly, the Modem is in training mode. If the DSL
light blinks slowly, DSL service has been lost; contact the ISP.

DSL Settings
To access DSL Settings, select DSL Settings from the “Advanced Setup” screen. The
Modem’s VPI, VCI, Mode, and QoS (Quality of Service) settings can be changed
from this screen, we recommend not changing these values without first consulting the ISP.
DHCP Settings
Selecting DHCP Settings in the “Advanced Setup” screen generates the “DHCP
Settings” screen. The Modem has a built-in DHCP (Dynamic Host Configuration
Protocol) server that automatically assigns a different IP address to each computer
on the network, eliminating IP address conflicts.
The factory default setting is On. To disable the DHCP Server, select Off, then
click Apply.
20
Chapter 4 Configuring Advanced Settings
We strongly recommend leaving the DHCP Server option On. If the DHCP Server
option is Off, ensure the IP addresses of the networked computers are on the same
subnet as the IP address of the Modem. For more information, see “DHCP Server
Configuration.”
DHCP Server Configuration
Clicking in the check box labeled “I would like to adjust the DHCP server settings”
activates the text boxes at the bottom of the DHCP Settings screen. Change the IP
address range and DNS server information in these text boxes.
Beginning IP Address
This is the IP address at which the DHCP server starts assigning IP addresses. We
recommend keeping the factory default setting (192.168.1.64).
Ending IP Address
This is the IP address at which the DHCP server stops assigning IP addresses. We
recommend keeping the factory default settings (192.168.1.254).
The beginning and ending IP addresses define the IP address range of the
Modem. If the default values are left intact, the Modem supplies a unique IP
address between 192.168.1.64 and 192.168.1.254 to each computer on the network. Note that the first three groups of numbers of the addresses are identical;
this means they are on the same subnet. The IP address of the Modem must
be on the same subnet as the IP address range it generates. For instance, if the
Modem’s IP address is changed to 10.33.222.1, set the beginning IP address to
10.33.222.2, and the ending IP address to 10.33.222.254.
Subnet Mask
Enter the IP address of the DHCP server’s subnet mask here.
Lease Time
This value represents the amount of time (in seconds) the DHCP server holds
onto a specific IP address.

Chapter 4 Configuring Advanced Settings
The “WAN IP Address” screen appears.
DSL Modem User Manual
WAN IP Address allows manual set up of the IP address of the Modem. To do this:
Note: Some DSL providers use PPPoE to establish communication
☞
with an end user. Other types of broadband Internet connections
may use either DHCP or static IP address. If unsure which connec-
tion is present, check with Verizon before continuing.
1. Select “DHCP” or “PPPoE,” depending on the type of connection the ISP uses.
If PPP Auto Connect is being used, click in the appropriate check box.
2. If PPPoE was selected in step 1, enter the user name and password in the
appropriate text boxes.
3. Select the IP type. If “Single Static IP Address” was selected, enter the IP
address in the “Single Static IP” text box. If “Multiple Static IP Addresses” was
selected, enter the designated gateway IP address and subnet mask address in
the “Gateway Address” and “Subnet Mask” text boxes respectively.
24
Chapter 4 Configuring Advanced Settings
4. Enable Public/Private IP Addressing. This feature is used in conjunction with
Multiple Static IP Addresses. When selected, the Modem uses NAT for private
IP addressing for the LAN, allowing both public and private IP addressing to be
configured to the LAN simultaneously, while the DHCP server is reserved for
private IP addressing. All computers using public IP addresses must have the
public IP addresses statically assigned.
5. Select the DNS type. If static DNS address was selected, enter the primary DNS
address and, optionally, the secondary DNS address in the appropriate text
boxes.
6. Select Dialout on-demand (optional). To have the Modem automatically
connect to the Internet whenever needed (when a Web browser is opened,
for example), activate “Dialout on-demand” by clicking in the appropriate
check box. When Dialout on-demand is activated, the user can also set the
Modem to disconnect from the Internet after a certain amount of idle time
(no Internet activity). To do this, enter the number of idle time minutes
(minimum 2 minutes) before disconnection occurs in the text box before
“Minutes.”
7. Adjust MTU settings (optional). Enter the maximum transmission unit (MTU)
value (in bytes) in this text box. This value corresponds to the largest physical
packet size the network is allowed to transmit. Packets larger than this size are
divided into smaller packets. It is recommended to leave this value set at the
default (1492).
When finished in this screen, click Apply to activate any changes made.
