And with MAXg, your network is protected with a maximum security suite of capabilities, including Wi-Fi Protected Access (WPA), WPA2/802.11i (AES Encryption), MAC address authentication, and more. In addition to providing state-of-the-art wireless connectivity, your MAXg gateway includes an integrated print server, allowing you to share your USB printer with other computers on your network and a 4-Port Ethernet switch for connecting Ethernet devices. Firewall - Stateful Inspection The U.S. Robotics Wireless MAXg ADSL Gateway provides firewall stateful inspection for intrusion detection. The gateway tracks all packets originating from the LAN and records each connection's address pair and the TCP/UDP port pairs. When receiving TCP/UDP packets from the Internet, the IP addresses and port numbers must match the tracking records. Otherwise, the gateway drops the packet. For ICMP packets, only outgoing ICMP request packets originating from the LAN are forwarded to the Internet, and its related incoming ICMP reply packets from the WAN side are allowed to come into the LAN. For example, you can ping any device on the Internet from a computer on the LAN, but you cannot ping the gateway or any LAN device from the Internet. Also, the gateway does not let ICMP redirect packets in, since they could be used to reroute traffic through attacking machines. The only exception to the above firewall rules occurs when remote technical support access is explicitly allowed by the local user. The gateway then responds to ping request packets and allows remote access to the gateway's Web User Interface (WUI). The gateway firewall also prevents LAND attacks and SYN floods:

SYN floods: the gateway firewall drops all unsolicited TCP SYN requests received from the Internet.

Land attacks: this type of attack forces a victim machine into an unending loop. The gateway firewall can prevent such attacks by disallowing any packets with the same source and destination address. Security - Remote and Local Access Accounts

The U.S. Robotics Wireless MAXg ADSL Gateway WUI provides a local admin account, a local non-administrative user account, and a remote technical support account, all with password protection. The support account allows the local administrative user to file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX60.547\featu... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 2 2 explicitly let a remote technician access the gateway's WUI.

The user account can view the configuration parameters but not change them.

The support account does not work in bridge mode since there is no public IP address assigned to the gateway.

The remote technical support user can read/write the configuration but cannot change security settings. When remote access security is enabled by a local administrator, the remote user can access the modem via telnet or a browser from the Internet, but not from the LAN.

The maximum length for user names and passwords is 15 characters. DHCP Server The gateway provides DHCP server service over the LAN interface when the network operating mode is set to PPPoE, PPPoA, MER or IPoA mode. When enabled, the DHCP server responds to DHCP request packets from LAN devices and assigns:

An unused IP address within the start-end IP address range configured by the user to the LAN device.

The gateway's LAN interface IP address as the primary DNS server address to the LAN device. The ADSL gateway performs DNS relay between the LAN device and the real DNS server at the remote service provider site.

The gateway's LAN interface IP address as the default gateway to the LAN device. DHCP Client The gateway provides DHCP client service for each Internet interface operating in the MER network operating mode. If enabled, the DHCP client requests the WAN interface IP address, primary and secondary DNS server addresses, and default gateway from the DHCP server at the service provider site. If the DHCP client function is disabled, the user must manually configure the WAN IP address, DNS server addresses and default gateway. DNS Relay The gateway provides DNS Relay service only when the NAPT function is enabled. It forwards he DNS inquiry packets received from the LAN devices to the primary DNS server at the remote site and vice versa. The DNS response packets received from the remote DNS server are relayed back to the LAN device.

Do not install a microfilter on the cable that connects your ADSL gateway to the telephone jack unless your microfilter has a connection for both the gateway and the phone. Step 2. Connect the Antenna and Cables To configure the gateway, you will initially use the supplied yellow Ethernet cable to connect it to the computer. You can set up a wireless connection later in the installation process, once the gateway is communicating with the Internet. This diagram shows you how the devices will be connected when the installation is complete:

To make the needed connections, follow these steps:

A. Attach the antenna to the back of the gateway. B. Connect one end of the telephone cable to the telephone port on the back of your gateway

(labeled ADSL). Connect the other end to the telephone wall jack. C. Connect the yellow Ethernet cable. Although you can connect up to four systems this way, you should connect additional devices only after the initial setup is complete. Insert one end of the Ethernet cable into one of the ports on the back of the gateway (labeled 1, 2, 3, and 4). Connect the other end to the Ethernet port on your computers network interface card. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX48.000\insta... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 3 7 D.

Enable log Description Click on one of these options to disable or enable the recording of log data. Log Level allows you to configure which types of events are logged. There are several levels of log events:

Emergency = system is unusable (these appear in red in the log)

Alert = action must be taken immediately (pale red)

Critical = critical conditions (orange)

Error = error conditions (yellow) Log level

Warning = warning conditions (green)

Notice = normal but significant conditions (blue)

Informational = information events (white)

Debugging = debug-level messages (dark grey on cream) The gateway records all log events at the chosen level and above. For instance, if you set the log level to Critical, all critical, alert, and emergency events are logged, but none of the others are recorded. This lets you choose the event level to display in the previous System Log page. This item uses the same event level ranking as Log Level above, but it applies to what events are displayed in the WUI rather than recorded. This lets you specify whether log events should be stored in the gateway's local memory, be sent to a remote log server, or both simultaneously. If you choose Remote, the system log will not show the events saved on the remote server. The remote server would be a syslog device, which you would need to set up. When you select either Remote mode or Both mode, this is the Internet address of the remote log server. When you select either Remote mode or Both mode, this is the communication port of the remote log server, to which the gateway will send log data. By convention, port number 514 is often used, but you can enter any port number you like. Display level Mode Server IP address Server UDP port 3.

It is recommended that you leave the Authentication method in Automatic, however, you may select PAP or CHAP if necessary. The default value for MTU (Maximum Transmission Unit) is 1500 for PPPoA and 1492 for PPPoE. Do not change these values unless your ISP asks you to. The gateway can be configured to disconnect if there is no activity for a specific period of time by selecting the Dial on demand check box and entering the Inactivity timeout. The entered value must be between 1 minute to 4320 minutes. The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specifically requires this setup, do not select it. If you need to select it, the PPP IP Extension supports the following conditions:

It allows only one computer on the LAN.

The public IP address assigned by the remote using the PPP/IPCP protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the computer's LAN interface through DHCP. Only one system on the LAN can be connected to the remote, since the DHCP server within the ADSL gateway has only a single IP address to assign to a LAN device.

NAPT and firewall are disabled when this option is selected.

The gateway becomes the default gateway and DNS server to the computer through DHCP using the LAN interface IP address.

The gateway extends the IP subnet at the remote service provider to the LAN computer. That is, the PC becomes a host belonging to the same IP subnet.

The ADSL gateway bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the gateway's LAN IP address. 3. After entering your settings, click Next. The following page appears:

Universal Plug-n-Play 802.1d spanning tree protocol Description This is the IP address that other devices on your local network will use to connect to the gateway. This defines the size of your network. The default is 255.255.255.0. The DHCP server assigns an IP addresses from a pre-set pool of addresses upon request from DHCP client (e.g. your computer). Do not disable the DHCP server unless you wish to let another device handle IP address issuance on the local network. This is the beginning and ending range for the DHCP server addresses. The amount of time before the IP address is refreshed by the DHCP server. Use this feature to create a public network on your local LAN, accessible from the Internet. By assigning an address to this interface and then statically setting your LAN clients to the same network, the LAN clients are accessible from the public network (e.g. FTP or HTTP servers). Universal Plug and Play is a Microsoft standard for devices to identify themselves to a Windows system for automatic installation and configuration. This resolves multiple bridged paths in a network. Only advanced users should enable this feature. DHCP server relay Inform the gateway of another DHCP server on your LAN. To do this, disable the DHCP server on the gateway. Then input the IP address of the current DHCP server. Click Apply and restart the gateway. Video Interfaces Use this page to re-direct ATM traffic to a specific Ethernet or wireless port, or a group of ports. An application such as multicast streaming of video data to set-top boxes requires this interface. Do not create a bridge group without dedicated ATM service from your Internet file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX03.015\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 3 8 Service Provider. Click on Add to create a new bridge group. Routing - Routing Table The routing table shows the IP addresses or address routes for the computers connected to the gateway to reach different destinations, such as the local network, the gateway, or the outside world beyond the gateway (i.e., the Internet). Here is an example of how it might look:

This table describes each row in the above example. Row Description 1 2 3 This row shows how the gateway gets to the ISP's gateway, using the pppoa_0_36_1 interface. This shows how the gateway communicates with the LAN interface, using the br0 interface. This data shows how the gateway accesses the Internet, using the pppoa_0_36_1 interface and the ISP's gateway at address 192.168.0.254. Routing - Static Route This page lets you set up static routes to connect machines not on the gateway's local network. A system is not on this local network if the third number in its IP address does not match the third number in the gateway's IP address (for example, if you haven't changed the file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX03.015\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 4 8 gateway's IP address from 192.168.1.x, a machine whose address does not have 1 as the third number is not on the local network). The page looks like this when no static routes have been defined:

To define a static route, click Add. Another page opens:

Specify settings and click Apply when done. This returns you to the previous page, which now shows the new static route data. Routing - RIP If you connect another router or gateway to your Wireless MAXg ADSL Gateway, the RIP feature helps the two devices share their routing tables. The gateway supports RIP versions 1 and 2. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX03.015\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 5 8 Under Operation, Active means that this gateway sends its routing table data to other gateways and routers, and Passive means that it receives this data from other devices but does not send it. Routing - ARP Table The ARP table shows the IP and MAC addresses for all computers that have transferred data to the gateway. Note: This table is not saved when you restart the gateway. DHCP Clients The DHCP client page shows the system name, MAC address, IP address, and the amount of time until session expiration for all computers connected to the gateway. The lease time is a maximum session length assigned by the gateway's DHCP server whenever a system logs on to it. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX03.015\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 6 8 Quality of Service The Quality of Service feature is useful when some of the traffic handled by the gateway has higher importance than other data being handled at the same time. For example, you might set up your computer to make telephone calls over the Internet. If you have a voice conversation while your computer is also downloading a file, you would want the voice conversation to take precedence over the file download, since delays in transmitting voice messages would cause signal dropouts and poor sound quality. How QoS works The QoS feature would help you if all of the following conditions are met:

The PVC is not in bridge mode (that is, the WAN protocol can be in PPPoA, PPPoE, IPoA or MER)

The PVC is set to one of the following ATM service categories:

UBR-with-PCR

UBR-without-PCR

Non-realtime-VBR

There are enough ATM TX queues left in the system. QoS classifies traffic according to classification rules you define. Each rule may contain a combination of the following conditions: protocol (TCP/UDP/ICMP), source IP address/subnet mask, destination IP address/subnet mask, source port (one or range), destination port (one or range). Any session that matches a classification rule receives a certain priority (high, medium, low) and a type of service (normal service, minimum cost, maximum reliability, maximum throughput, or minimum delay). The priority of the matching rule determines which ATM TX queue to send over the PVC if the packet is routed to this PVC. ATM picks packets to process according to these priorities:

1. ATM service categorizes from the highest to lowest order: CBR, rt-VBR, rrt-VBR, UBR. 2. For the same service category: Priority level from high, medium, to low. 3. For the same priority level: round robin. QoS only works for QoS-enabled PVCs. If data is routed to a regular QoS-disabled PVC, it will receive the same priority level as the low priority of a QoS-enabled PVC in the same ATM service category. Enabling QoS To enable the QoS feature, follow this procedure:

1. Go to the Internet menu and select WAN Setup. 2. From there, click either Add or Edit. 3. In the resulting page, click Enable Quality of Service. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX03.015\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 7 8 Configuring QoS To set up QoS, you define one or more classes of data traffic.

Field AP isolation Band Channel Rate Multicast rate Basic rate Fragmentation threshold RTS threshold Description Enable this item if you do not want your wireless machines to be able to communicate with each other. This is the range of frequencies the gateway will use to communicate with your wireless devices. Drop-down menu that allows selection of specific channel. This drop-down list lets you specify the wireless communication rate, which can be Auto (uses the highest rate when possible, or else a lower rate) or a fixed rate between 1 and 54 Mbps. This drop-down list lets you specify the wireless communication rate for multicast packets, which are sent to more than one destination at a time. The value can be Auto (uses the highest rate when possible, or else a lower rate) or a fixed rate between 1 and 54 Mbps. You have the option of supporting all rates listed in Rate above or using the 1-, 2-Mbps rates, which support only older 802.11b implementations. A threshold, specified in bytes, that determines whether packets will be fragmented and at what size. On an 802.11 connection, packets that are larger the fragmentation threshold are split into smaller units suitable for the circuit size. Packets smaller than the specified fragmentation threshold value are not fragmented. Enter a value between 256 and 2346. If you experience a high packet error rate, try to increase this value slightly. Setting the fragmentation threshold too low may result in poor performance. This is number of bytes in the packet size beyond which the gateway invokes its RTS/CTS (request to send, clear to send) mechanism. Packets larger than this threshold trigger the RTS/CTS mechanism, while the gateway transmits smaller packets without using RTS/CTS. The default setting of 2347, which is the maximum, disables the RTS threshold mechanism. A delivery traffic indication message (DTIM), also known as a beacon, is a countdown informing wireless clients of the next window for listening to broadcast and multicast messages. When the file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX06.125\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 5 5 DTIM interval Beacon interval Acceleration MAC address 54g mode 54g protection WMM (Wi-Fi multimedia) WMM no-

The clients hear the beacons and awaken as needed to receive the broadcast and multicast messages. The amount of time (in milliseconds) between beacon transmissions, each of which identifies the presence of an access point. By default, wireless clients passively scan all radio channels, listening for beacons coming from access points. Before a client enters power-save mode, it needs the beacon interval to determine when to wake up for the next beacon

(and learn whether the access point has any messages for it). You can enter any value between 1 and 65535, but the recommended range is 1 - 1000. MAXg is a feature in which two U.S. Robotics MAXg devices can communicate with each other at twice the normal rate. 54g+ is a technology that achieves higher throughput with frame-bursting. With 54g+ enabled, aggregate throughput (the sum of the individual throughput of each network client) improves by up to 25% in 802.11g-only networks, and up to 75% in mixed networks containing both 802.11g and 802.11b equipment. In this item, you can select either None, 54g+

(Xpress?, or MAXg (125 Mbps). If you are in Bridge mode, MAXg (125 Mbps) is not supported. This is the gateway's WLAN MAC address. Set this 54g+ mode to 54g Auto for the widest compatibility, or to 54g Performance for the fastest performance with 54g-certified equipment. The 802.11g standards provide a protection method so 802.11g and 802.11b devices can co-exist in the same network without speaking at the same time. Do not disable 54g protection if there is a possibility that a 802.11b device will use your wireless network. In Auto mode, the wireless devices use RTS/CTS to improve 802.11g performance in mixed 802.11g/802.11b networks. Turn protection off to maximize 802.11g throughput under most conditions. This item enables or disables Quality of Service

(QoS) processing of multimedia packets. In QoS, some types of packets are given a higher priority than others. No-acknowledgement refers to the acknowledge policy used at the MAC level. Enabling no-

acknowledge can result in more efficient throughput but high error rates.

WEP open and WEP shared WEP is an encryption scheme that is used to protect your wireless data communications. WEP uses a combination of 64-bit keys or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each wireless client on the network must use an identical 64-bit or 128-bit key. WEP is an older wireless encryption method that is not as hard to break as the more-recent WPA.

802.1x In 802.1x (also known as RADIUS), a separate machine called an authentication server receives a user ID and password. It grants or denies access based on whether the ID and password match any entries in its account list. You can optionally enable WEP encryption with this option. Because it requires a separate machine acting as the authentication server, 802.1x is most often used in business enviroments.

WPA with 802.1x (RADIUS) WPA is a more recent encryption method that addresses many of the weaknesses in WEP. Any client capable of WPA encryption should use it instead of WEP. This option uses WPA and an authentication server.

WPA (PSK) This is WPA encryption combined with a pre-shared key (PSK), which is a text string known only to the gateway and authorized wireless clients. The gateway rejects the login if the client's PSK does not match.

WPA2 with 802.1x (RADIUS) WPA2 is a more advanced encryption method than WPA. Because it is a more recent standard, some of your wireless devices might not be able to use it. This option specifies WPA2 encryption and an authentication server.

WPA2 (PSK) This option uses WPA2 with a pre-shared key.

WPA2 and WPA with 802.1x (RADIUS) This option supports an authentication server and WPA2/WPA encryption for devices capable of one or the other standard. The gateway automatically detects whether a particular device can use WPA2 or WPA.

WPA2 AND WPA (PSK) This has WPA2 or WPA encryption based on client abilities, as well as a pre-shared key. After making changes, click Apply to save. MAC Filter All network interface cards are built with a unique 48-bit MAC address. When MAC address file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 3 10 filtering is enabled, you can restrict the wireless devices that are allowed to connect to your gateway by their respective MAC addresses. You could also grant access to any wireless device whose MAC address is on its "allow" list. These are the values for the MAC restrict mode:

Allow all Allow any wireless device to access your local network, which amounts to turning off MAC filtering.

Allow these Let only the devices with the MAC addresses in the MAC filter list have access to your wireless network.

Deny these Exclude only the devices with the MAC addresses in the MAC filter list from accessing your wireless network. Allow access to any other MAC addresses. Below the MAC restrict mode is a table showing all MAC addresses that the restrict mode applies to. You can add up to 60 addresses to the list. For an example of adding MAC addresses to the list and otherwise configuring MAC filtering, please see the Tutorials section of this User Guide. If you wish to delete an entry from the list, select the appropriate MAC restrict mode, select the Remove checkbox for the entry you want to delete, and click the Remove button. Device Login You can use this page to change the password for the admin, support and user accounts.

(Their default passwords are admin, support, and user respectively.) Simply select an account in the User name drop-down list, then enter the current and new passwords for the account. Enter the new password a second time to confirm it. Then click Apply to save the new password. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 4 10 Internet Access Control You can use the Internet Access Control page to create a parental control rule that keeps certain network devices off the Internet for specific time periods. The rules can block access for a defined time period on certain days of the week. Note: If you want to use this feature, you must configure the gateway to synchronize its time with at least one Internet time-of-day server. See Time synchronization for more information. This is the Internet Access Control page when there are no filters defined:

Click Add to define an Internet access filter, and enter its settings in the following page. In addition to the rule name, each rule you define has the MAC address of the machine to block, the time period to block it for, and a list of days that the time-period block is enforced. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 5 10 Caution: If you want to set up access control for a machine other than the one you're currently using, select Other network device and enter that device's MAC address. After configuring the Internet access filter, click Save to save it. Here's what it might look like if you wanted to keep children off the Internet during after-school study hours:

IP Filtering - Outbound Filters The gateway's firewall can block internal users or applications from accessing the Internet. There are two ways to accomplish this:

Using the TCP/UDP port numbers to block internal users or applications (a technique called port filtering). file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 6 10

Using a combination of the source or destination port, protocol or source/destination IP address to block a specific machine from accessing the Internet. This is also known as address filtering. The outbound filter page allows you to block outgoing packet types using either TCP, UDP, or a combination of both from specific ports. For a tutorial on how to use the outbound filter page to keep a computer from accessing the Internet, please click here. This is the outbound filtering page before adding a filter:

To remove an existing filter definition from the outbound filter table (the first screen shown above), check the Remove checkbox for the filter and click the Remove button. The following page appears after you click Add. When you are done entering values for your filter, click Apply to save the filter. These are the fields on the second page above (the page labeled Add IP Filter and Outgoing), where you define a filter that specifies a set of conditions for which to block access for one or more local machines. Description Item Filter name Enter a name for the filter here. Protocol Select TCP, UDP, a combination of TPC & UDP, or ICMP. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 7 10 Enter the subnet mask for the source IP address. Enter the IP address that you do not want to let access the Internet or the destination address. Source IP address Source subnet mask Source port Enter the source port number, or range of ports, for which you want to block access. Destination Enter the IP address you do not want the source IP address IP address to have access to. Destination subnet mask Enter the subnet mask for the destination IP address. Destination port Enter the destination port number, or range of port numbers, you want to block access. IP Filtering - Inbound Filters This page allows incoming packets to reach their intended destinations by specifying rules for unblocking certain incoming packets. You could use it any time you want to allow restricted access to a machine, or you could configure unlimited access to a particular system (for example if one of your local machines is a Web server). Click on Add to create a new inbound filter. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 8 10 This table describes the fields in this Add IP Filter page:

Description Field Filter name Enter a name for your inbound filter here. Protocol Source IP address Selects TCP, UDP, or a combination of TCP/UDP. Enter the external IP address you want to allow access to your internal address that appears in the Destination IP address field. Source subnet mask Enter a subnet mask for the source IP address. Source port Enter a source port number, or a range of port numbers. Destination IP address Destination subnet mask Enter a subnet mask for the destination IP address. Destination Enter the destination port number, or range of port port numbers, you want to allow access (for the destination IP). Enter the internal IP address you want to provide access to. After setting up your filter, click Apply to save it. Virtual Servers A virtual server allows you to direct incoming traffic from the Internet (identified by protocol and external port) to an internal server with a private IP address on the LAN. If you need to convert an external port you need to enter an internal port. Click here to go to a tutorial showing you how to set up a virtual server. If you want to delete a virtual server, check the Remove checkbox for the appropriate line in the table and click Remove. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 9 10 Note: If you set up a DMZ host, all packets for addresses other than those specified in this page go to a designated DMZ machine. Port Triggering Port triggering is similar to a virtual server, except that it creates a dynamic or temporary hole in the firewall. Port triggering is more secure than a virtual server, but it does not support simultaneous use of the same ports by multiple systems. It allows remote systems access through the gateway's firewall. Click Add to set up port triggering for an Internet application. In the next page (shown below), select the application name, which fills in the settings in the table below. If the application you want is not in the list, select Custom application and fill in the table parameters below. (See the application's documentation to find out what the settings should be.) Click Apply to save the port trigger. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 10 10 Note: A port trigger is available to a single active session. It cannot simultaneously support same-port triggers to multiple clients. DMZ Host The de-militarized zone (DMZ) option is for forwarding IP packets from the Internet that are not meant for any of the applications configured in the virtual server table. These packets are forwarded to a designated DMZ host computer. While a virtual server can only forward

(redirect) a limited number of services (ports), DMZ hosting allows all the services (ports) running on the DMZ host to be accessible externally. This is the DMZ Host page. To configure the DMZ, simply enter the IP address of the computer that will function as the DMZ host. Click Apply to save the DMZ address. To deactivate the DMZ feature, clear DMZ host IP address and click Apply. 2004-2005 U.S. Robotics Corporation. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX25.500\wui_... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 1 8 Wireless MAXg ADSL Gateway User Guide Home Installation Configuration Help Login Status Internet LAN Wireless Security Device Appendix Device settings These are the options available in the Device menu:

For the printer_name part, use the name you entered in Printer name on the Print Server page shown above. This name is case-

sensitive, and it must exactly match the Printer name on the Print Server page. 5. You will be prompted to choose the brand and model of your printer. You can either select them from the list or click Have Disk, then insert the CD-ROM that came with your printer, and navigate to your CD-ROM drive to locate the drivers. When you are finished, click Next. 6. When prompted, select Yes or No to set this printer as your default printer. If prompted, you can print a test page. 7. You will be shown the information regarding your printer. Click Finish to complete the setup process. 4. To verify the printer connection, print a page from this computer. If this prints correctly, your printer setup is complete. If not, make sure the printer is turned on and that the USB cable is firmly connected to both the printer and to the gateway. If the page still does not print correctly, repeat the setup procedure and make sure you enter all the correct information. Back Up Settings To save your gateway configuration settings, click Back Up and specify a file location on your hard drive. Note: If you are using Internet Explorer 5.5 or earlier, the WUI will display the settings on the screen rather than save them to a file.

This means that only a single unique IP address represents an entire group of devices to the outside world. Implementing dynamic NAPT automatically creates a firewall between your internal network and the Internet. NAPT only allows connections that originate inside the internal network. Essentially, this means that a computer on an external network cannot connect to your computer unless your computer has initiated the contact. Nobody from the outside can latch onto your IP address and use it to connect to a port on your computer. Under NAPT, all internal network computers are inaccessible from the outside. However, if you need to use public services such as Web, FTP, or e-mail servers from your private network, you can set up a virtual server to permit secured access. In this method, a connection with the outside is redirected to a host (the virtual server) running the services on the private network. (IP forwarding is another term for this.) The Virtual Servers setup page allows you to add, remove, and save virtual server settings.

The problem is that some of these applications set the Web browser to use a proxy server to listen to incoming connection requests. 1. In your Web browser, go to the user connection preferences and enable Using proxy. Set the type to SOCKS 4. 2. Disconnect and reconnect. 3. Set the type back to Not using proxy and change settings to use the ports you specify. You should now be able to make a functioning connection. Be sure to disconnect/reconnect after you make every change. 4.

The gateway's quality of service (QoS) feature is executed in its IP software. It classifies traffic according to the classification rules. Each rule may contain a combination of the following conditions: protocol (TCP/UDP/ICMP), source IP address/subnet mask, destination IP address/subnet mask, source port (one or range), destination port (one or range). The result of matching a classification rule is to produce a priority (high, medium, low) and a type of service (normal service, minimum cost, maximum reliability, maximum throughput, minimum delay). Example: Suppose your company hosts an Internet radio station. Lately, the quality of the radio stream has not been very good since many people at the company are browsing the Internet and using up the company's bandwidth. A good solution would be to set high priority for the radio broadcast, and low priority on Web traffic. Here is how you could do it. 1. Access the gateway's Web user interface (WUI) by opening an Internet browser and entering http://192.168.1.1 NOTE: If the browser does not open successfully, please go to the Troubleshooting section. 2. Enter your user name and password. The default user name is admin, as is the default password. Click OK or press ENTER. The WUI then opens. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX08.359\tutor... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 2 3 3. In the LAN menu, select Quality of Service. 4. The Quality of Service page appears:

5. Click Add. 6. The first QoS entry will be for the HTTP Web traffic. In the page shown below, type the name of the service in the field labeled Traffic class name. Next, set the Priority, IP precedence, and IP type of service. In this example we are setting the priority to Low because we are trying to improve the quality of the radio stream by limiting Web traffic. Lastly, type in the Source port and Destination port. It should look like this when you're done:

Confirm that you are using the AC power adapter that came with your gateway and that it is connected to the gateway and to an active wall outlet. Make sure the Power switch is switched to the on position. The LED should be lighted. 2. Confirm that you have securely connected the telephone cable to the telephone wall jack and to the gateway. The correctly configured DSL. LED should be lighted if you have ordered and 3. If you are using a wired connection from the computer to the gateway, confirm that you have secured the Ethernet cable(s) to the computers network interface card and to the Ethernet port(s) on the gateway (labelled 1, 2, 3, or 4). The corresponding LED should be lighted on the front of the gateway. For more information on the LEDs, see the Status LEDs section earler in this document. Opening the Web user interface The Web user interface will be your main tool for configuring, troubleshooting and monitoring the gateway. Follow this procedure to access it. 1. Start a Web browser. 2. Open the page http://192.168.1.1 (If youve modified the gateways LAN IP address, you must use the new one.) 3. A login window should appear:

The default user name and password are already filled in. Click OK. 4. The Web user interface opens with a status page. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX16.109\troub... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 2 5 If you cannot access the Internet... A number of devices have to work together for your computer to access the Internet. NOTE: For completeness, the following drawing shows both wired and wireless connections between your computer and your U.S. Robotics Wireless MAXg ADSL Gateway. Youll normally use only one type of connection on each computer. A. Your computer connects to your Wireless MAXg ADSL Gateway via a wireless or wired connection. B. The gateway connects to your Internet Service Provider (ISP) via ADSL over the phone network. The first step in solving the problem is to diagnose the cause. There are a number of places where the connection from your computer to the Internet might fail. Windows users: You can check your connections automatically with the included utility program. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX16.109\troub... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 3 5 1. Use Windows Explorer to navigate to the Troubleshooting folder on your U.S. Robotics installation CD-ROM (for example, D:\Troubleshooting, if your CD drive is labeled D:). 2. Double-click on Troubleshoot_Connection. This utility program tests your connections and, if there is a problem, tells you where it is. Step 1: Can your computer connect to your Wireless MAXg ADSL Gateway?

Open a Web browser to the gateways address: http://192.168.1.1 (Please note that if youve modified the gateways LAN IP address, you must use the new one.) If the gateways Web user interface appears, go to Step 3. Otherwise, the gateway may need to be restarted:

1. With a thin tool such as a paper clip, briefly press the Reset button on the back of the gateway. 2. Wait one or two minutes as the gateway restarts. If you use a wired connection:

If you use a cable connection between your computer and the gateway, ensure that one end of the Ethernet cable is connected to your computers LAN port and the other end is connected to one of the Ethernet ports on the gateway. Also check that the corresponding LED is lighted. In the unlikely event that your computer is using a static IP address, either re-configure your computer to use a dynamic IP address or ensure that its static IP address is in the same network as the ADSL gateway. (That means that the IP address has the format 192.168.1.x where x can be any number between 2 and 254, inclusive.) Now, please restart your computer. It will attempt to connect to the gateway. Proceed to Step 2. If you use a wireless connection:

1. Ensure that your computer is close enough to your gateway to receive a wireless signal and that there is nothing interfering with the signal, such as a microwave oven or a concrete wall. If your gateway broadcasts its network name, you can use your computers wireless utility to scan for it. (This is typically called a site survey.) If the utility cannot detect the gateway, it may be a signal problem. 2. Ensure that the computers wireless utility is using the correct network name and security settings for your gateway. Settings such as network name, security method (WPA, WEP, etc.), and security keys must all match. So if your gateway is using WPA encryption, each wireless card or adapter must support WPA encryption. If you are using a wireless PC card, PCI adapter, or USB adapter that does not support WPA encryption, you will not be able to connect to the gateway unless you use WEP encryption instead. Please click here for information on changing the security settings. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX16.109\troub... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 4 5 3. If you have enabled MAC filtering on the gateway, is this computer permitted to connect to your gateway?

Please note that MAC filtering refers to specific wireless adapters. If you use MAC filtering and have added a new wireless adapter to the network, you must add the MAC address of the new wireless adapter to the gateway. NOTE: If you need to modify the ADSL gateways settings, youll need a computer with a wired connection to the gateway in order to access it. If these steps fail to establish a wireless connection, please try a wired connection between your computer and your gateway. Connect the yellow Ethernet cable to your computers LAN port and to a LAN port on the gateway. Then ensure that the corresponding LAN port LED is lighted. Then please restart your computer. Step 2: Is your Wireless MAXg ADSL Gateway responding?

Open your Web browser to the gateways address: http://192.168.1.1 NOTE: If you can open the gateways Web user interface with a wired connection but not with a wireless connection, the problem is with the wireless connection. Please see the documentation for your wireless adapter. If the gateways Web user interface appears, please go to Step 3. If the gateways Web user interface doesnt appear, the gateway may need to be restored to the default factory settings. (Please note that you will lose all of your gateways custom settings and will need to set it up again as if you were installing it for the first time. If youve made a backup of the settings, you will be able to restore them. Please click here for more information.) 1. With a thin tool, such as a paper clip, press the Reset button on the back of the gateway for at least five seconds. 2. Wait about one or two minutes as the gateway restarts. 3. Please restart your computer so that it will connect to the gateway. 4. Try to access the gateways Web address at http://192.168.1.1 If the gateway's Web user interface still does not appear, the firmware and/or default factory settings may have been corrupted. To find out, follow these steps:

1. Press and hold down the Reset button on the back of the gateway for more than 30 seconds. 2. Assign a static IP address to your computer, in the same subnet as your gateway's management IP address. (For example, the default management IP address for your gateway is 192.168.1.1. The computer IP address can be 192.168.1.5, subnet mask 255.255.255.0, and gateway IP address 192.168.1.1.) 3. Open a browser and try to open the http://192.168.1.1 address again. If anything opens, follow the on-screen instructions to re-load the firmware. You will need to get a new firmware file from your Internet Service Provider or from the www.usr.com Web site. 4. Close the Web browser and return your computer to a dynamic IP address. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX16.109\troub... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 5 5 If the gateways Web user interface still does not appear, the gateway may have failed. Please contact U.S. Robotics Customer Support. See the contact information in the Help section of this guide. If the gateways Web user interface appears, please continue to Step 3. Step 3: Can your Wireless MAXg ADSL Gateway connect to the Internet?

ADSL employs different upstream and downstream data rates. The asymmetric name refers to these differing rates. AH (Authentication Header) RFC2402 defines AH. AH provides integrity and authentication through the shared key hashing algorithms (HMAC-MD5, HMAC-SHA1). AH provides authentication for as much of the IP header as possible. AH also authenticates upper level protocol data. AM (Amplitude Modulation) Modulation method used by modems, radio, and DSL equipment. The signal modulates or alters the amplitude or intensity of the carrier. In regular AM, the carrier is a sinewave. The amplitude of the modulated carrier changes in proportion to signal amplitude. AM creates two identical sidebands on either side of the carrier. These sidebands contain the signal data. Either sideband can be attenuated or suppressed without harming the signal data. With an equivalent signal, AM tends to require less bandwidth than FM does. AM's disadvantage is that it's more subject to impulse noise and static than FM is. Application Level Gateway (ALG) - Some applications embed IP addresses within the IP payload. The U.S. Robotics Wireless MAXg ADSL Gateway supports several ALGs, each addressing a special application. The ALG replaces the private IP Address embedded within a particular application payload. ATM(Asynchronous Transfer Mode) - Protocol that packs digital information into 53-byte cells. The cells switch throughout a network over virtual circuits. Average Cell Rate - Maximum sustainable or average rate (cells/second) for sending cells to the network. Average Cell Rate specifies bandwidth utilization. This value must always be less than or equal to Peak Cell Rate. B Bandwidth - Amount of data that can be transmitted over a given time period. BPDU (Bridge Protocol Data Unit) - Data messages exchanged across switches in an extended LAN with a spanning tree protocol topology. BPDU packets assure that data arrives at the intended destination. These packets contain information on addresses, costs, ports, and priorities. Network loop detection involves exchanging BPDU messages across bridges. Loop deletion entails placing redundant switch ports in a backup (blocked) state and shutting down selected bridge interfaces. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX57.500\gloss... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 2 9 Bridge A device that connects two LAN segments together. These LAN segments may be of similar or dissimilar types, such as Ethernet and Token Ring. Inserting a bridge into a network segments the network. The bridge improves performance by keeping traffic contained within bridge segments. Bridge Loop - Path that links one network segment to another. The spanning tree protocol avoids bridge loops. Bridge Priority - Determines which bridge becomes the root bridge. Burst Size (Cells) - Maximum number of cells that the user can send at peak rate in a burst. We measure burst size from within a sustainable rate. C CAP (Carrierless Amplitude and Phase Modulation) Modulation method used by modems and DSL equipment. Based on QAM. Signals modulate two wideband signals using passband modulation. CAP permits two to nine bits per frequency cycle. Carrier wave - Periodic waveform. A carrier may be modulated or unmodulated. It may also be continuous or switched. Typically, modems modulate the carrier wave with a data signal. Modulation represents the data signal by impressing a variation on some characteristic of the carrier wave. For instance, a circuit may represent the signal as a proportional shift in carrier amplitude, frequency, or phase. Demodulation (detection) eliminates the carrier wave and reproduces the signal. The carrier frequency must be significantly greater than the signal frequency. A modem may simultaneously apply more than one signal and more than one modulation method to the same carrier. The modulation method may suppress the carrier before transmission. In that case, the receiver must reinsert the carrier before demodulation can occur. CBR (Constant Bit Rate) - Service type that supports real-time applications with a fixed bandwidth. These applications, such as a video stream, produce data at regular intervals. The user can specify how much bandwidth that he wishes to reserve. CDVT (Cells) - Parameter that constrains the number of cells that the user can send to the network at the maximum line rate. Cycle - One half of a periodic wave. For instance, a sinewave includes one positive and one negative cycle. D DHCP (Dynamic Host Configuration Protocol) - Protocol for automatic TCP/IP configurations. DHCP provides static and dynamic address allocation and management. DHCP Relay - Suppose that a Dynamic Host Configuration Protocol (DHCP) server resides on a different LAN than the node broadcasting for DHCP service. Then the DHCP broadcast request must be forwarded across the gateway/WAN to a subnet where a DHCP server resides. To assure receipt of an IP address that corresponds to this subnet, the gateway must use a DHCP relay. The gateway needs to know the IP address of the DHCP server. With this address, the gateway can direct the request to the appropriate DHCP server. DMT (Discrete Multitone) - Most common DSL modulation method. DMT creates 256 channels across the usable frequency spectrum. Each channel measures 4.3125KHz wide. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX57.500\gloss... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 3 9 Dividing the spectrum into channels allows DMT to function well in spite of nearby AM radio transmitters. The DMT modulator and demodulator is the FFT (Fast Fourier Transform) algorithm. Inside each channel, the modulation technique is QAM. Within each channel, the number of bits per symbol may be independently selected. Independent selection allows a DMT modem to be rate adaptive. Both G.DMT and G.Lite use DMT. DNS (Domain Naming System) - Mechanism used in the Internet for translating names of host computers into IP addresses. DNS Relay - DNS requests that the gateway forwards from a LAN node to a known DNS server. The gateway uses a DNS relay when the gateway functions as a NAPT (Network Address Port Translation) device. The requests arrive at a DNS server over the WAN link. To function as a NAPT, the gateway requires DNS relay settings. DSLAM (Digital Subscriber Line Access Multiplexer) - Network device that receives signals from multiple customer Digital Subscriber Line connections. DSLAM places signals on high speed lines with multiplexing techniques for the fastest phone line technology available. E ESP (Encapsulating Security Payload) ESP provides confidentiality. Optionally, ESP also provides integrity, authentication, anti-replay service, and limited traffic flow confidentiality. Options selected at the time of Security Association establishment determine provided services. For confidentiality, shared ESP supports shared key encryption algorithms, such as DES and Triple DES. F Filter - Operating parameter used in LAN bridges and gateways. When set, the filter causes bridges and gateways to block transfer of packets between LANs. The term "filter" also applies to a hardware device, such as a microfilter. When installed, this device reduces interference between DSL signals and telephone signals. Forward Delay Time - Timeout value employed by all bridges in the bridged LAN. The root sets the forward delay value. FM (Frequency Modulation) Modulation method used by modems, radio, and DSL equipment. The signal modulates or alters the frequency or pitch of the carrier. In regular FM, the carrier is a sinewave. The frequency of the modulated carrier changes in proportion to signal amplitude. FM creates an infinite number of sidebands. These sidebands contain the signal data. With an equivalent signal, FM tends to require more bandwidth than AM does. FM's advantage is that it's less subject to impulse noise and static than AM is. Frame - Variable length information unit that contains packets. Also refers to a transmission frame, a fixed-length unit that carries bits across a physical link. A transmission frame is a framed transport component. DSL technologies use frames. Also refers to a frame of video, one image in a video sequence G Gateway - Entrance to and exit from a communications network. G.DMT - The ADSL standard approved by the International Telecommunications Union (ITU). G.DMT indicates full-rate ADSL, which provides standards for higher speed ADSL than G.Lite. G.DMT provides maximum data rates of 8 Mbps downstream from the subscriber and 1.5 file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX57.500\gloss... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 4 9 Mbps upstream from the subscriber. G.lite - Standard way to install Asymmetric Digital Subscriber Line service. Over regular phone lines, G.Lite makes possible Internet connections to home and business computers at up to 1.5 Mbps. Officially known as G.992.2. H Hello Time - Time interval between generations of configuration BPDUs. The root bridge generates configuration BPDUs. I-J-K ICMP - (Internet Control Message Protocol) - A TCP/IP protocol for sending error and control messages. For example, a gateway uses ICMP to notify the sender that the gateway's destination node is unavailable. A ping utility sends ICMP echo requests to verify the existence of an IP address. Internet Assigned Numbers Authority (IANA) - Internet Assigned Numbers Authority

(IANA) uses three blocks of IP address space, namely 10.0.0.0/8 (class-A) 172.16.0.0/ 12

(class-B), and 192.168.0.0/16 (class-C) for private internets. Interface Name - Gateway interface that will be configured. IP (Internet Protocol) - Protocol that allows a packet of information to travel through many networks and LANs. IP Address - IP addresses deliver packets of data across a network. These addresses differentiate the source and destination IP address and keep them constant. When a gateway port detects a packet, the gateway checks the routing table. The port attempts to match the network number of the destination IP address with its routing table entry. If the port finds a match, it forwards the packet to the destination network. With no match, the port forwards the packet to a gateway defined as the default gateway. L LAN (Local Area Network) - Network base covering a local geographic area. A LAN connects computers in the same building or area. Link Cost - Cost associated with the interface. Based on this cost, the bridge decides which link to forward data over. M MAC Address (Local Area Network) - Unique serial number burned into Ethernet adapters. Distinguishes the network card from others. Max Age Time Timeout value that all bridged LAN bridges use. The root bridge sets the Max Age value. MAC Filter (Local Area Network) - Method of allowing or rejecting WAN access for specific machines. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX57.500\gloss... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 5 9 Microfilter - Device that separates the ADSL data signal from the telephone signal so that the ADSL data signal does not interfere with the telephone device. Modulation - Varying elements of electrical carrier waves in a manner that represents signal data. Demodulation restores the signal data. A modulated signal requires more bandwidth and an unmodulated signal does. The bandwidth increase results from the creation of sidebands during modulation. The sidebands contain the signal. AM creates two, identical sidebands on either side of the carrier. FM creates an infinite number of sidebands. MTU (Maximum Transmission Unit) - Parameter that limits the size of packets that transmit on an interface. Not all interfaces support the MTU parameter. Some interfaces, like Ethernet, have range restrictions (80 - 1500). N-O NAP (Network Access Point) - Public network exchange facility where ISPs connect while peering. NAP connections determine how the Internet routes traffic. Network Address Port Translation (NAPT) - Network Address Port Translation (NAPT) translates multiple private IP addresses and their LAN side TCP/UDP ports, into a single public IP address on the WAN side and its TCP/UDP ports. This is necessary as private IP addresses are not valid nor routable in the public network. Many homes and small offices have multiple PCs or network devices. Using private IP addresses and NAPT in the U.S. Robotics Wireless MAXg ADSL Gateway, multiple LAN devices can access remote networks or the internet with just one public IP address assigned by their ADSL service provider. When configuring the gateway for PPPoE or PPPoA operating mode, NAPT is always automatically enabled. For MER or IPoA operating mode, there is an option available to enable or disable the NAPT. For any IP packet sent to the WAN, the NAPT function replaces the source private IP address in the IP header with the public IP address of the WAN interface, and replaces the TCP/UDP source port number with a unique port number. Vice versa, it translates the destination public IP address and the destination port number within the IP packet received from the WAN interface back to the originating PC's private IP address and it's original TCP/UDP port number. Next Hop IP - IP address or Gateway used to arrive at the destination address. NRT-VBR (Non Real Time-Variable Bit Rate) - Service type that supports applications that have no constraints on delay and delay variation, but still have variable-rate and burst traffic characteristics. P PAM (Pulse Amplitude Modulation) Modulation method used by modems and DSL equipment. The signal modulates or alters the amplitude or intensity of the carrier. In regular AM, the carrier is a sinewave. In PAM, the carrier is a periodic series of DC pulses. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX57.500\gloss... 2005/7/4 U.S. Robotics Wireless MAXg ADSL Gateway User Guide 6 9 PCM (Pulse Code Modulation) - Digital modulation method for transmitting analog data. PCM signals are binary. These signals can represent any analog data with only two states, logic 0 and logic 1. PDM (Pulse Duration Modulation) Modulation method. Signal modulates or alters the duty cycle of the pulse. In PDM, the carrier is a pulse stream. Also called PWM (Pulse Width Modulation). Peak Cell Rate - Maximum rate (Cells/second) for sending cells to the network. Phase - Position of a periodic waveform. PM (Phase Modulation) Modulation method used by modems, radio, and DSL equipment. The signal modulates or alters the phase or position of carrier waves. In regular PM, the carrier is a sinewave. The phase of the modulated carrier changes in proportion to signal amplitude. Port Priority - Parameter that determines which port becomes the root bridge port. POTS (Plain Old Telephone Service) - Basic voice service available in residences throughout the United States. PP (Point-to-Point Protocol) Communication protocol for dialing up the Internet over a serial link. Such serial links include a POTS and an ISDN line. PPP establishes the session between the user's computer and the ISP. PPP uses the Link Control Protocol (LCP), which also handles authentication (PAP, CHAP, etc.), compression, and encryption.

PVC (Permanent Virtual Circuit) - Virtual connection between two fixed endpoints on the network. Frame relay and ATM networking term. PWM (Pulse Width Modulation) Modulation method. Signal modulates or alters the duty cycle of the pulse. In PWM, the carrier is a pulse stream. Also called PDM (Pulse Duration Modulation). Q QAM (Quadrature Amplitude Modulation) Modulation method used by modems and DSL equipment. Combines two amplitude-modulated (AM) signals into a single channel. The modem inserts the signals 90 degrees (one-quarter cycle) out of phase with each other. Engineers call this 90-degree phase shift "quadrature." QAM modulates both carrier phase and amplitude. Doubles effective bandwidth. R RAM (Random Access Memory) - Primary memory in a computer. The computer can overwrite this type of memory with new data. The "random access" part of RAM derives from the way RAM stores data: The computer can locate any bit of information in RAM in an equal amount of time. This fact applies regardless of where the bit resides. RIP (Routing Information Protocol) - Routing protocol and part of the TCP/IP suite. RIP determines a route based on the smallest hop count between source and destination. RIP determines the smallest hop count by communicating with other gateways within the network. Only use RIP if the target gateway also utilizes RIP. RJ-11 - Six-conductor modular telephone jack wired for up to four wires. The most common telephone jack in the world is the RJ-11. This connects telephone instruments, modems, and fax machines to a female RJ-11 jack. The female jack often mounts to the wall or floor. RJ-45 - Eight-conductor modular telephone jack. Used for 10BaseT, ISDN and other data connections. Router - Device that forwards data packets between local area networks (LANs) or wide area networks (WANs). Referring to routing tables and routing protocols, routers read the network address in each transmitted packet. Routers then decide where to send the packet. A router bases this decision on the best route. When a router port detects a packet, the router checks the routing table. The port attempts to match the network number of the destination IP address with its routing table entry. If the port finds a match, it forwards the packet to the destination network. With no match, the port forwards the packet to a router defined as the default gateway. RT-VBR (Real Time-Variable Bit Rate) - Service type that supports time-sensitive applications such as voice. Varies the rate at which cells arrive.

Modulation of the carrier creates sidebands. The sidebands contain the signal data, but consume bandwidth beyond what the carrier needs. In some cases, circuitry may suppress duplicate sidebands without harming the signal data. For instance, AM becomes single sideband when circuits delete one of two identical AM sidebands. Some single sideband equipment also suppresses the carrier frequency. The carrier must then be restored at the receiver before the signal can be demodulated, that is, recovered. Spanning Tree-Bridging - Particular algorithm or formula. Transparent bridges use the spanning tree algorithm to dynamically determine the best source-to-destination path. This algorithm avoids bridge loops (multiple paths that link one segment to another) within a network. The algorithm determines all redundant paths and makes only one of them active. The spanning tree protocol (STP) is part of IEEE standard 802.1. Splitter - DSL device that accommodates analog telephones, plus digital data access over the Internet. With a splitter, analog voice signals transmit at baseband frequencies. These combine with passband data transmission through a low-pass filter. Static routes - Permanent routes that the gateway stores. The gateway uses these routes when determining where to forward IP packets that it receives. Subnet Mask - Portion of a network. Distinguished from other portions by the use of a mask or subnet number. Subnet masks split one network into a set of mini networks or subnets. Subnetting helps to reduce traffic on each subnet. Subnetting also makes the network more manageable. Each subnet functions as if it were an independent network. SVC (Switched Virtual Circuit) - Virtual connection between two variable endpoints on the network. The switch makes at the beginning of the call, and breaks at the end of the call. A frame relay and ATM networking term. T TCP/IP (Transmission Control Protocol/Internet Protocol) - Set of protocols designed to link dissimilar computers that use various networks and LANs. Topology - Geometric physical or electrical configuration that describes a local communication network. The most common distribution system topologies are the bus, ring, and star. U UDP (User Datagram Protocol) - A protocol within the TCP/IP protocol suite. When reliable delivery is unnecessary, communications may use UDP instead of TCP. UBR (Unspecified Bit Rate) - Best effort service that does not require tightly constrained delay and delay variation. UBR provides no specific quality of service or guaranteed throughput. UPnP (Universal Plug and Play) - With UPnP enabled in the U.S. Robotics Wireless MAXg ADSL Gateway, all UPnP aware applications running in the LAN-devices with UPnP (such as Windows XP) can pass through the NAPT.

USB (Universal Serial Bus) - External bus standard that supports data transfer rates of 12 Mbps. V VCI (Virtual Channel Identifier) - Address of a virtual circuit. An integer that ranges from 0 to 65,535. The integer identifies a virtual channel that cells may traverse. VPI (Virtual Path Identifier) - Address of a virtual path to a connection on an ATM network. An integer that ranges from 0 to 4,095. W WAN (Wide Area Network) - Network base that covers a large geographic area. WINS (Windows Internet Name Service) - Service that transposes Windows networking names into addresses usable for routing purposes. 2004-2005 U.S. Robotics Corporation. file://C:\Documents%20and%20Settings\ivonne\Local%20Settings\Temp\Rar$EX57.500\gloss... 2005/7/4
