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.
DSL Modem User Manual Internet Light The Internet light glows green when connected to the ISP. It may blink while sending or receiving data. Ethernet Light The Ethernet light illuminates when the Modem is connected to a computer via its yellow Ethernet port, using an Ethernet cable. USB Light The USB light illuminates when the Modem is connected to a computer via its USB port, using a USB cable.
Chapter 1 Introduction Ethernet Port The Ethernet port is used to connect computers to the Modem via Ethernet cable. The Ethernet port is a 10/100 Mbps auto-sensing port, and either a straightthrough or crossover Ethernet cable can be used when connecting to the port. ☞ Note: Use a crossover Ethernet cable to connect the Modem only if connecting to a hub/switch that lacks an uplink port. Reset Switch Depressing the Reset switch restores the Modem’s factory default settings.

Configuring Advanced Settings # 4 This chapter explains how to configure the Modem’s advanced settings, such as remote management, DHCP settings, and Quality of Service (QoS). Accessing Advanced Setup Screens To access the Advanced Setup screens, follow these instructions: 1. Open a Web browser. In the “Address” text box, type: http://192.168.1.1 then press Enter on the keyboard.
DSL Modem User Manual 2. The “Home” screen appears. Click Advanced Setup. 3. A login window appears. Enter the user name and password in the appropriate text boxes, then click OK.
Chapter 4 Configuring Advanced Settings Internet Explorer: ☞ Note: The default user name is “admin.” The default password is “password.” 4. The “Advanced Setup” screen appears. To modify a specific configuration, click on its name in the menu bar on the left, or from the list in the middle of the screen.
DSL Modem User Manual 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.
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.
DSL Modem User Manual Domain Name This is the domain name provided by Verizon. If Verizon provided domain name information, enter it here. If not, leave the text box intact. DNS (Dynamic or Static) This is the type of DNS server provided by Verizon. If Verizon provided DNS server information, select the type here. If not, leave as is. DNS Server 1 This is the primary DNS server provided by Verizon. If Verizon provided DNS server information, enter it here. If not, leave the text box intact.
Chapter 4 Configuring Advanced Settings The values in the “Modem IP Address” and “Modem Subnet Mask” text boxes are the IP and subnet mask address of the Modem as seen on the network. These values can be modified for your LAN network, but we recommend keeping the default factory settings (IP address 192.168.1.1; subnet mask address 255.255.255.0). the Modem’s Address is modified, verify the ☞ Note: IfServer range is within the same subnet. For more inforLAN IP DHCP mation, see “DHCP Server Configuration.
DSL Modem User Manual The “WAN IP Address” screen appears. WAN IP Address allows manual set up of the IP address of the Modem. To do this: Some providers use o to establish communication ☞ Note: with an end user. Other types of broadband Internet connections DSL PPP E may use either DHCP or static IP address. If unsure which connection is present, check with Verizon before continuing. 1. Select “DHCP” or “PPPoE,” depending on the type of connection the ISP uses.
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.
DSL Modem User Manual QoS Settings Upstream Selecting QoS Settings Upstream from the “Advanced Setup” screen causes the “QoS Upstream Settings” screen to appear. QoS (Quality of Service) allows the prioritization of certain types of data traffic (such as VoIP traffic) over other types of traffic (such as standard data). Both upstream (data coming into the network) and downstream (data going out of the network) traffic can be prioritzed using QoS.
Chapter 4 Configuring Advanced Settings Total Available Bandwidth Displays the total amount of available bandwidth (in kilobits per second). High Priority Bandwidth Enter the amount of high priority bandwidth to be used by the prioritized traffic type (cannot exceed total available bandwidth).

Computer Security C The Internet is a giant network of computers located all over the world. When a computer is connected to the Internet, it can exchange information with any other computer on the Internet. This allows a computer user to send e-mail, surf the World Wide Web, download files, and buy products and services online, but it also makes the computer vulnerable to attack from persons intent on doing malicious mischief, or worse.
DSL Modem User Manual Modem Security If connecting to the ISP through Point-to-Point Protocol (PPP), be sure to provide the Modem an administrative password. If a password is not set, someone on the Internet can access the Modem and change its configuration or steal your PPP login name and password. For instructions on setting the password, see the “Advanced Setup chapter. If connecting to the ISP through bridging mode, the Modem should be safe from unwarranted and illegal intrusion.
Appendix C Computer Security Network Applications Network applications (such as software programs) that allow remote access to the computer also make the computer vulnerable to access from other people on the Internet. If using a network application that allows remote access, consider installing a firewall. Electronic Security Here are two methods to secure your computer electronically.
