# About the U.S. Robotics USB ADSL Modem

The U.S. Robotics USB ADSL modem is compatible with any PC equipped with a USB port. As a Plug and Play device, Windows 98 First Edition (FE), 98 Second Edition (SE), 2000, and Millennium (Me) will automatically recognize the U.S. Robotics USB ADSL modem and initiate the installation process.

## FEATURES

### Packaging Checklist

U.S. Robotics USB ADSL package includes:

- One U.S. Robotics USB ADSL Modem (Model #USR8500-USB)
- One USB cable, modem-to-computer (Type B to Type A)
- Standard RJ-11 telephone cable
- One Installation CD-ROM with manual and drivers inside
- One Quick Installation Guide
- One registration card (complete and return to U.S. Robotics)

Inform your dealer if there are any incorrect, missing, or damaged parts.

### LED Functions

The U.S. Robotics USB ADSL Modem contains two LEDs on the top panel. The upper LED is marked "PWR" and the lower LED is marked "Data." The operational status of the modem is indicated by the LED conditions listed below.

LED | Status | Description
Data | Flashing Green | Indicates the modem is synchronizing its ADSL/ATM link with the DSLAM.
On Green | Indicates an ADSL/ATM link has been established with the DSLAM.
PWR | On Green | Power is being supplied to the modem via the USB bus.

### Power Requirements

USB devices can be either self-powered or bus-powered. A device with no power connector is bus-powered and derives its operating power from the USB connection directly. The U.S. Robotics USB ADSL Modem is bus-powered - all you need to do is plug it into a host PC.

### Prerequisite Information

The following information may be required, depending on the driver you install. Contact your DSL service provider before proceeding with software installation.

- IP Address Settings - the software installation process allows the server to dynamically assign IP Address settings. If your application requires a static setting for specific address information you will need to know the following:
  - IP Address
  - Subnet Mask
  - Default Gateway
- Name Server Information - the modem software installation process allows the server to dynamically assign Name Server Address settings. If your application requires a static setting for specific address information you will need to know:
  - Primary DNS Address
  - Secondary DNS Address
- Virtual Path Identifier (VPI)*
- Virtual Circuit Identifier (VCI)*
- Encapsulation type*
- Modulation type*
- User Name (for PPP applications only)
- Password (for PPP applications only)

*These items are only required if you are not using default values.

# Troubleshooting

My computer did not recognize the modem.

Possible Solution:

- Make sure that the USB cable is connected to the USB port located in the back of your PC.
- If a second USB port in the back of your PC is available, connect the USB cable into this USB port.
- Make sure the USB cable is securely plugged into the modem.
- Check the computer provider's documentation if the USB devices are not recognized.

The drivers are installed, the power LED is ON, the phone line is connected, but the data light is off or keeps flashing.

Possible Solution:

- Make sure that the phone line is securely attached at both ends of the modem and the wall jack.
- Insure there is NO phone line filter between the modem and the wall jack.
- Insure that microfilters are placed between the wall adapter and any telephones, fax machines, answering machines, or any other non-DSL telephone equipment. (Microfilters are usually supplied by your DSL Internet Service Provider)
- Unplug the USB cable from the modem for 2-3 minutes but leave the phone line connected. Plug the USB cable back into the modem. This should cause the modem to reconnect.

After configuring the TCP/IP settings, the modem does not establish a connection to the Internet.

Possible Solution:

- Double-check the ATM settings of the modem. Click the DSL icon in your Windows system tray located in the right, lower corner of the screen near the clock, or go to the Control Panel by clicking Start, Settings, and Control Panel. Double-click U.S. Robotics USB ADSL Modem.
- In the U.S. Robotics Application, click the Configuration tab and verify that the VPI, VCI numbers and the Encapsulation settings match what your DSL Internet Service Provider has provided. If they are not correct, refer to the documentation and/or CD-ROM provided by your DSL Internet Service Provider.

The installation failed.

Solution:

You will need to uninstall the failed installation.

1. Click Windows Start, select Settings followed by Control Panel.
2. Click Add/Remove Programs.
3. Locate the U.S. Robotics USB ADSL Modem and double-click U.S. Robotics USB ADSL Modem. You may have to scroll down to locate this program.

# Glossary

ADSL (Asymmetric Digital Subscriber Line) - Transports information to and from customers and networks.

ATM (Asynchronous Transfer Mode) - This is a protocol that packs digital information into 53-byte cells which are switched throughout a network over virtual circuits.

Bandwidth - This is the amount of data that can be transmitted over a given time period.

DSLAM (Digital Subscriber Line Access Multiplexer) - This is a network device that receives signals from multiple customer Digital Subscriber Line connections and places them on higher speed lines with multiplexing techniques for the fastest phone line technology available.

DHCP (Dynamic Host Configuration Protocol) - This is a protocol for automatic TCP/IP configurations providing static and dynamic address allocation and management.

DNS (Domain Naming System) - This is a mechanism used in the Internet for translating names of host computers into addresses.

Encryption Type - This is the mathematical process whereby encoding information is created for the purposes of ciphering data.

Filter - This is an operating parameter used in LAN bridges and routers that when set, will cause these devices to block the transfer of packets from one LAN to another.

G.lite - Officially known as G.992.2, it is now a standard way to install Asymmetric Digital Subscriber Line service. G.lite makes it possible to have Internet connections to home and business computers at up to 1.5 Mbps over regular phone lines.

G.dmt - This refers to the ADSL standard approved by the International Telecommunications Union (ITU). G.dmt indicates full rate ADSL which provides standards for higher speed ADLS than G.lite. G.dmt provides maximum data rates of 8 Mbps downstream to the subscriber and 1.5 Mbps upstream from the subscriber.

Gateway - This is an entrance and an exit to a communications network.
IP (Internal Protocol) - This allows a packet of information to travel through many networks and LANs.

LAN (Local Area Network) - This is a network base covering a local geographic area.
Modulation Type - A modulation is the process of varying characteristic elements of the electrical carrier waves.

POTS (Plain Old Telephone Service) - This is a basic voice service available in residences throughout the United States.

RAM (Random Access Memory) - The primary memory in a computer, this is memory that can be overwritten with new information. The random access part of its name comes from the fact that the next bit of information in RAM can be located - no matter where it is - in an equal amount of time.

RJ-11 - This is a six-conductor modular telephone jack wired for up to four wires. The most common telephone jack in the world, the RJ-11 is typically used for connecting telephone instruments, modems and fax machines to a female RJ-11 jack on the wall or in the floor.

Subnet Mask - This is a portion of a network and is distinguished from other portions by the use of a mask or subnet number.

Splitter - This is an analogue voice transmitted at baseband frequencies and combined with the passband data transmission via a low-pass filter.

TCP/IP (Transmission Control Protocol/Internet Protocol) - This is a set of protocols designed to link dissimilar computers using a variety of networks and LANs.

Topology - The geometric physical or electrical configuration describing a local communication network. The most common distribution system topologies are the bus, ring, and star.
USB (Universal Serial Bus) - This is a new external bus standard that supports data transfer rates of 12 Mbps.

VCI (Virtual Channel Identifier) - This is the address of a virtual circuit.

VPI (Virtual Path Identifier) - This is the address of a virtual path corresponding to a connection on an ATM Network.

WAN (Wide Area Network) - This is a network base covering a large geographic area.

WINS (Windows Internet Name Service) - This is a service transposing Windows networking names into useable addresses for routing purposes.
