*IMPORTANT! In accordance with the ITU-T standard for 56K transmissions (V.90), this modem is capable of 56 Kbps downloads. However, the download speeds you experience may lower due to varying line conditions and other factors. Uploads from users to server equipment travel at speeds up to 31.2 Kbps. An analog phone line compatible with the V.90 standard, and an Internet provider or corporate host site compatible with the V.90 standard is necessary for these high-speed downloads.

Use the Modem Installation Assistant! The Modem Installation Assistant is a new software tool that will make the installation of your modem even easier in Windows 95, 98, and 2000. In addition, Windows 95 and 98 users can view a video presentation on installing the modem. In Windows 95 and 98, it will check for the system resources that your modem needs, help you free system resources if none are available, and give you step-by-step instructions or a video presentation on installing your modem.

To use the Modem Installation Assistant, insert the Installation CD included with your modem into your CDROM drive. The Modem Installation Assistant should run automatically. If it does not, click Windows Start and then click Run. In the “Run” dialog box, type D:\setup.exe. If your CD-ROM drive uses a different letter, type that letter in place of “D.”

The Modem Installation Assistant will then go to work. Follow the onscreen instructions to use the Assistant. When the Assistant tells you to shut down your computer, refer to Step One of this Guide to continue the installation process.

Before You Begin

Write the modem’s serial number in the box below. The serial number is located on the white bar code sticker on the modem and on the modem’s box.

your computer. You will need to press the modem in firmly so that it is seated properly in its slot. When the modem is installed correctly, you will no longer see any part of the black edge. See the front of this guide for complete instructions. If your modem still does not work, with your computer off, remove the modem and reinstall it in another slot if possible.

PROBLEM: My computer isn’t recognizing my modem.

Possible solution:

You may be using an IRQ that is already in use. To work properly, your modem needs to be assigned to a free IRQ.

Windows 2000Windows 2000

Windows 2000

If you set your modem’s jumpers to Plug-and-Play mode, Windows should locate a free IRQ, if one exists, for your use by your modem.

If Plug-and-Play fails to install the modem, you need to determine IRQ availability. Right-click the My Computer icon on your desktop. Click Properties, and then the Hardware tab. In the Device Manager section, click Device Manager. From the View menu, select Resources by type. Click Interrupt Request (IRQ). You will now see a listing of your system’s IRQs and the devices to which they are assigned. If an IRQ is not present in this list, it indicates that Windows is not currently using it and the IRQ is considered available.

Locate your modem in the list of devices. If a yellow exclamation point appears over the modem’s description, your modem is in conflict with another device. Either your modem or the other device will have to be reinstalled to another IRQ in order to resolve your conflict.

If a usable, free IRQ does not exist, you may need to remove, disable, or relocate another device. Refer to that device’s documentation for more information about removing, disabling, or relocating it.

If Windows still fails to recognize your modem and it does not have a yellow exclamation point next to its IRQ, or if your modem doesn’t appear in the list, another problem exists, and you may need to call 3Com Technical Support.

Windows 95/98

If Plug-and-Play fails to install the modem, you need to determine IRQ availability. Right-click the My Computer icon on your desktop. Click Properties, and then the Device Manager tab. Double-click the Computer icon at the top of the device list. You will now see a listing of your system’s IRQs and the devices to which they are assigned. If an IRQ is not present in this list, it indicates that Windows is not currently using it, and the IRQ is considered available.

Windows NT

Turn off your computer and physically remove the modem. Restart your computer, and check for an available IRQ by clicking Windows Start, Programs, Administrative T ools, and Windows NT Diagnostics. Click the Resources tab and select IRQ. T ake note of an available IRQ that your modem can use. If there are no IRQs available, you may have to remove, disable, or relocate another device in order to free an IRQ for use by your modem. Refer to that device’s documentation for more information about removing, disabling, or relocating it.

Possible solution:

You may be using a COM port address that is either already in use or not configured correctly. T o work properly , this modem needs to be assigned to a free COM port.

Windows 2000Windows 2000

Windows 2000

Make sure your COM port is not already in use by another modem. Click Windows Start, Settings, and Control Panel, and then double-click Phone and Modem Options. Click the Modems tab. Look for another modem already in the machine. If there is another modem listed, check which COM port it is using. If a previous modem is already using the available COM port, you can either use another COM port or uninstall the previously installed modem. See your previous modem’s manual for uninstallation instructions.

Right-click the My Computer icon on your desktop. Click Properties.

Click the Hardware tab. In the “Device Manager section”, click the Device Manager button. Look under Ports (COM & LPT). If the Communications Ports have yellow exclamation points or red Xs over them, your COM ports may be configured incorrectly. If this is the case, you may need to contact your computer manufacturer. It is also possible that you may be plugging an external modem’s cable into a disabled serial port. Refer to your computer’s manual for information about enabling COM ports. This usually involves altering the BIOS settings and possibly the operating system. You may need to call your computer’s manufacturer to change your BIOS settings if they are incorrect.

Windows 95/98

Make sure your COM port is not already in use by another device. Click Windows Start, Settings, and Control Panel, and then double-click Modems. Look for another modem already installed in your computer. If there is another modem installed, click the Diagnostics tab to find out which COM port it is using. If a previously installed modem is already using the available COM port, you should uninstall that modem. See your previous modem’s manual for uninstallation instructions.

Right-click the My Computer icon on your desktop. Click Properties. Click the Device Manager tab. Double-click Ports. If the Communications Ports have yellow exclamation points or red Xs over them, your COM ports may be configured incorrectly. If this is the case, you may need to contact your computer manufacturer.

Windows NT

Turn off your computer and remove your modem. Restart and click Windows Start, Settings, and then Control Panel. Doubleclick the Ports icon. Your modem must be set to a COM port setting that does not appear in this list.

PROBLEM: My software isn’t recognizing my modem.

Possible solution:

Your communications software may not function properly if you have more than one version of the software installed, you are using an older version, or you have more than one communications application installed on your system. We highly recommend using the communications software provided with your modem on the Installation CD-ROM.

Possible solution:

Your software’s COM port settings may be incorrect. There should be a place in the Setup section of your software that addresses port settings. Make sure the software’s port settings match those for your modem. To check which COM port your modem is using, click Windows Start, Settings, and Control Panel. Double-click Modems, select your modem, and select Properties. Check your communication software’s documentation for instructions on adjusting the port settings in your software.

Possible solution:

You may not have the correct modem type selected in your software or in Windows. Click on Windows Start, Settings, and Control Panel. When Control Panel opens, click Modems. You will see a list of installed modems. You can also add, remove, or view the properties of modems from this window. The 3Com U.S. Robotics modem you have installed should be present in the list of installed modems. If none of the modem descriptions in the list match your 3Com U.S. Robotics modem or no modems are listed, your modem is not installed properly. Try reinst alling your modem.

Possible solution:

If you are using Dial-Up Networking, it may not be configured correctly. Check your configuration and make sure you have the correct modem selected. Double-click My Computer, doubleclick Dial-Up Networking, right-click the connection you are trying to use, and click Properties. Make sure that the description in the modem box matches the description of the modem you are using. If it doesn’t match, select the proper modem description.

PROBLEM: My modem won’t dial out or doesn’t answer incoming calls.

FOR BOTH DIALING AND ANSWERING PROBLEMS:

Possible solution:

You may have a bad phone cord connection to your modem, or your phone cord may be plugged into the wrong jack. The phone cord

should be plugged into the

jack on the modem and into the wall

phone jack. Use the phone cord included in your modem’s box if possible.

Possible solution:

You may have devices between the modem and the phone jack. There should be no line splitters, fax machines, or other devices between the modem and the wall jack.

OFFICE USERS:

Possible solution:

You may have plugged your modem’s phone cord into a digital line. Contact the department responsible for your phone system if you are unsure whether or not your phone line is digital.

If your phone system requires dialing “9” to access an outside line, be sure to add “9” before the number you are dialing.

VOICE MAIL USERS:

Possible solution:

If you have voice mail provided by your local phone company, your dial tone may be altered when messages are waiting. Retrieve your voice mail to restore your normal dial tone.

PROBLEM: My modem sounds like it’s trying to connect to another modem but fails.

Possible solution:

You may have a poor connection. All calls are routed differently, so try placing the call again.

PROBLEM: My modem isn’t achieving a 56K Internet connection.

Note: Due to current FCC regulations, maximum download speed is

limited to 53,333 bps. Our research has shown that the vast majority of telephone lines in

North America can and do support V .90connections. The V.90 protocol allows for connection speeds of up to 56K, but line conditions may affect the actual speeds during a given connection. Due to unusual telephone line configurations, some users will not be able to take full advantage of V.90 technology at this time. In order to achieve a V .90 connection:

• The server you’re dialing in to must support and provide a digital V.90 signal. Your ISP can provide you with a list of dial-up connections and information on what those connections currently support.

• The telephone line between your ISP and your modem must be capable of supporting a 56K connection and contain only one analog-to-digital conversion. The 56K signal from your ISP begins as a digital signal. Somewhere between the ISP and your modem, there will be a digital-to-analog signal conversion so that your modem can receive the data. There must be no more than one analog-todigital signal conversion in the path from your ISP to your modem. If more than one analog-to-digital conversion occurs, your connect speeds will default to V.34 (33.6 Kbps). There may also be impairments on the local lines between your ISP and your modem. These impairments can prevent or limit V.90 connection speeds. All telephone calls are routed differently, so you should try making your 56K connection several times. One way to test this is to dial into a long distance location. Long distance lines are often much clearer than local lines. It is important to note that telephone companies are constantly upgrading their systems. Lines that do not support 56K today may support 56K in the near future.

• Your modem must be connecting to a V .90/56K server . A pair of 56K modems will not connect to each other at V.90/56K speeds.
