Welcome

Welcome to the Intel® PRO/DSL Modem Help. Here you can find answers to the most common questions you may have about your new DSL adapter. You will also find troubleshooting information to help with any problems that may arise.

Click "Help Topics" to see available information and troubleshooting tips.


What are the Minimum System Requirements?

Generally, your Intel® PRO/DSL Modem will work with whatever the minimum hardware requirements are for the operating system you are using. Windows* 95, Windows 98, Windows Millennium Edition (Windows ME), Windows NT, Windows 2000, and Windows XP are all supported operating systems for this product.

You will need at least 10Mb of free space on your hard drive and an available bus mastering PCI slot in your computer.

You must also have a mouse or other pointing device on your computer.


What Version of Microsoft's Dial-Up Networking is Required?

The Intel® PRO/DSL Modem software requires that Dial-Up Networking version 1.3 (DUN 1.3) be installed. The modem Setup program will check for this software. If it is not installed, the Setup program will offer to install it for you. If you have an older version of DUN, or if you have the correct version of DUN but it is not enabled, the Setup program will give you the opportunity to upgrade or enable DUN.


What if Setup does not detect my modem?

If the Setup Wizard doesn’t start or your modem is not detected, choose one or more of the possible reasons below to troubleshoot:

The modem is not installed

The modem is not seated correctly

The driver did not get loaded

The modem is not in a bus mastering slot


Why doesn't my modem show up in Device Manager as a modem?

The Intel® PRO/DSL Modem is actually a network adapter. DSL adapters are typically called "modems", even though they do not MOdulate/DEModulate. You will find the modem listed in the Networking Adapters section. It will also appear as an adapter under Control Panel > Networking.


How do I install the Modem with Windows NT?

You will not use the Intel Setup program on the CD to install the Intel PRO/DSL Modem with Windows NT. Instead, please follow the instructions below to install and configure your modem.

The first step you must take to install your modem is to make sure you have received all necessary information from your ISP. You’ll need to know whether your connection is RFC 1483 (Bridged Ethernet) or Point-to-Point Protocol over ATM (PPPoA). You may need to know the VPI and VCI numbers (the DSL "phone numbers"). If you will have a static connection to the Internet, you will need to know your IP address and Subnet Mask numbers.

Initial steps:

1	Turn off your computer.

2	Install the Intel PRO/DSL Modem in an available PCI slot.

3	Power up the system.

4	Open the Network Control Panel (Start > Settings > Control Panel > Network). Select the Adapters tab and click Add. If NT networking has not been installed, a wizard will start. Skip to step 6 if you run the wizard.

5	Ensure that the PRO/DSL Modem CD is in your CD drive, then select "Have Disk".

6	Enter the drive letter of your CD drive followed by "NT4" (for example, d:\NT4), and click OK.

7	In the "Select OEM Option" dialog box, select the appropriate driver. If you are not sure whether to choose the 1483 or PPPoA driver, contact your ISP to obtain this information. Click OK once you have selected the driver.

8	If you selected the 1483 driver, proceed to step 15. If you selected the PPPoA driver, proceed to step 9.

9	If you selected the PPPoA driver, Windows NT displays a message that the system has successfully set up the Intel® PRO/DSL Modem, and that you must now configure Remote Access Service (RAS). Click OK.

10	In the Remote Access Setup dialog, click Add. (This may happen automatically if you don’t have any RAS devices already installed.)

11	In the Add RAS Device dialog, select "ADSL1 ¯ ProDsl21" from the list of RAS capable devices. Click OK.

12	Click Continue.

13	You may see a warning message about reinstalling your service pack. Click OK.

14	Click Close to finish installing the driver.

15	If you are installing the 1483 driver, refer to the file NT1483.wri in the \NT4 folder on the Intel PRO/DSL Modem CD for instructions on how to configure TCP/IP.

16	Restart Windows NT when prompted.

17	After restarting, ensure that Service Pack 4 or greater is installed. If not, install the latest Windows NT 4 service pack at this time. It is important that you upgrade to the latest service pack AFTER you install the driver. (Installing the service pack first, then installing the modem driver, can actually nullify some of the service pack’s changes.)

Configure the Driver:

There are separate instructions for each of the two protocols supported by the PRO/DSL Modem. The instructions are in WordPad files located in the \NT4 folder on the Intel CD.

•	For instructions for the Point-to-Point Protocol over ATM (PPPoA) driver, refer to NTPPP.wri.

•	For instructions for the Bridged Ethernet (RFC 1483) protocol, refer to NT1483.wri.


What does the LED on the back of the adapter indicate?

The LED is an external indicator showing you the state of your modem and connection. It can show these states:

Solid Green: Indicates a link with the telephone company equipment. (Your modem is trained.)

Flashing Green: Indicates the modem is passing traffic.

Amber: Indicates that the modem is establishing a link with the telephone company. (Your modem is training.)


How do I uninstall the modem software?

To uninstall the modem software, choose the link below that is appropriate for the operating system you are using.

Windows 95

Windows 98/ME

Windows NT

Windows 2000/XP

The uninstall process will completely remove the installed modem software. It will not remove any update to TCP/IP or Dial-Up Networking, even if either of these were installed during Setup. Use Add/Remove Programs from the Windows* Control Panel to uninstall these options.

NOTE:   After uninstalling the modem software, the next restart of the computer will re-detect the hardware and the Setup program will run again. If you do not want the system to detect the hardware again, please remove the Intel PRO/DSL Modem from the computer.

Baud

An attenuation variable. The telephone company’s Central Office (CO) determines the baud rate based on the service that you have purchased. The default baud rate should be set to the highest value. You can intentionally limit the baud rate for the adapter by setting a lower baud parameter.

Default VCI

The default VCI value for the PPPoA driver. VCI is also the VCI value that will be used by the 1483 (Bridged Ethernet) connection. It is a value between 0 and 63. In a PPPoA connection, the VCI value specified in the Dial-Up Networking connectoid takes precedence over a value entered in Advanced Properties.

Default VPI

The default VPI value for the PPPoA driver. VPI is also the VIP value that will be used for the 1483 connection. It is a value that can range between 0 and 3. In a PPPoA connection, the VPI value specified in the Dial-Up Networking connectoid takes precedence over a value entered in Advanced Properties.

Transmit Power

A control that allows you to adjust the amount of power transmitted from the CPE. Normally, this value is set to FULL. However, you may need to lower the transmit power value if you are very close to the telephone company’s Central Office. Only change this value when instructed by technical support.


My Modem Can't Connect

There are different reasons why your modem may not be able to form a connection to your ISP.

My modem is not training. (What is training ?)

My modem trains but will not log on or pass traffic.

My modem trains but drops the connection.


What are the numbers in my Dial-Up Networking phone number?

DSL does not use a conventional phone number. Instead, it uses a combination of two numbers to direct its route to the telephone company. This number is called VPI/VCI (Virtual Path Identifier/Virtual Channel Identifier). An example of a VPI/VCI number is 1,1.

These numbers show up as the phone number when using a PPPoA connection type. Any other format will be ignored. Your telephone company generally assigns these numbers, although your ISP may also be able to provide them to you. Area codes or call waiting override codes are unnecessary and will be ignored.


I have two phone lines. Which one has DSL?

On the DSL modem you will find two RJ-11 (phone jack) connectors. One is for your DSL line and one is an optional jack where you can attach a voice phone. The modem has a built-in microfilter that filters all DSL signals going to the phone attached to the modem’s other phone connector.

To verify which line your DSL service is on, connect a telephone to the second connector on the modem. Make a phone call to the number that you think hosts the DSL service. If that phone rings, that is the line that the DSL service is on. If it doesn’t ring, try the other number.

Did the correct number ring through to the telephone? If not, contact your telephone company to ensure that they have connected DSL to the number that you specified.


What do the green lights represent in Connection Manager?

Connection Manager provides a set of three green lights as indicators. All lights MUST be green before you can browse the Internet. If any one of the lights is not lit, your DSL connection is not functioning properly. View the Help file on the Connection Manager ¯  General Tab for troubleshooting information about your connection.


How can I check my connection speed?

You can check the speed of your connection by launching the Intel® PRO/DSL Connection Manager. Your connection speed appears on the Statistics tab. In most DSL installations, it is quite typical for the downstream speed to far exceed the upstream speed.


How do I open Connection Manager?

To view Connection Manager, double-click the PRO/DSL Connection Manager icon located in the Windows* system tray. (The tray is usually located in the bottom right-hand corner of your screen.)


How can I check my connection status?

You can check your connection status by launching the Intel® PRO/DSL Connection Manager. The three green lights give you a quick glance at the status of your connection; if any of the three is unlit, your DSL services are not functioning properly.

Other connection status information is available on the Statistics tab. If you need to contact your ISP or the telephone company for technical support, having Connection Manager available during the call will be very helpful.


How do I check my line quality?

To check your line quality, start Connection Manager and select the Statistics tab.

If you have an Intel PRO/DSL 2100 Modem (CAP encoding), look at the Line Quality statistic.

If this number is between 15 and 18, you may have in-home wiring that does not meet the minimum cabling requirements. If the number is less than 15, you may not even be able to train. (Maximum dB in this field is 45.)

If you have an Intel PRO/DSL 2200 Modem (DMT encoding), look at the SNR Margin statistic.

If this number is below 6, you may have in-home wiring that does not meet the minimum cabling requirements.

See "In-Home wiring does not meet minimum requirements"  for information about fixing wiring problems.

After checking your home wiring, you may need to call the telephone company technical support for additional assistance. They may need to verify that the wiring problem is inside your house, and not on the lines between your house and the CO.


How do I check or change my IP address settings?

About IP addresses

DSL and the Internet use TCP/IP as the protocol to transport data across the World Wide Web. Your IP address is how your system is identified on the Internet. You must have an IP address to be on the Internet.

To verify that you have an IP address, launch Connection Manager and select the ISP Info Tab. There must be a valid IP address displayed. If the IP address field reads N/A or 0.0.0.0, you do not have your connection set up correctly.

Types of IP Addresses

There are two methods used to assign IP addresses to computers ¯ Server Assigned (Dynamic) and Static (Permanent).

Server Assigned (Dynamic) IP addresses are assigned randomly to you each time you connect to your ISP. These numbers are assigned from a pool of IP addresses that the ISP owns. The ISP uses a technology called DHCP to dynamically assign addresses.

Static (Permanent) IP addresses are also assigned to you by your ISP from their pool of available IP addresses. However, unlike dynamic addresses, if you are given a static address, it will be your machine’s permanent address. (This is the preferred option if you are hosting a web server.)

When you ran the Intel® Setup program, you were asked to select which method your ISP uses to give you an IP address. If you selected the incorrect method or input the wrong static IP address or subnet mask, you will not be able to pass traffic on the Internet.

To verify your IP settings for Bridged Ethernet (1483) in Windows 95, 98, or ME:

1	Right click on the Network Neighborhood icon (Remember ¯ The Intel® PRO/DSL Modem is actually a network adapter)

2	Select Properties

3	Select TCP/IP > Intel PRO/DSL Modem

4	Select Properties

5	Verify that the settings are correct according to your ISP’s instructions.

To verify your IP settings for Point-to-Point Protocol over ATM (PPPoA)  in Windows 95, 98, or ME:

1	Double-click on My Computer

2	Double-click on Dial-Up Networking

3	Right-click on the icon for your DSL service provider

4	Select Properties

5	Select the Server Types tab

6	Click TCP/IP Settings

7	Verify or change your settings to match those given to you by your ISP.

To verify your IP settings with Windows NT:

1	Open the Network control panel. (Start > Settings > Control Panels > Network)

2	Click the Protocols tab.

3	Highlight TCP/IP Protocol, and click Properties.

4	Select the Intel PRO/DSL Modem from the drop-down menu.

5	Verify or change your IP address settings to match those given to you by your ISP.

6	If you need to configure static addresses, after entering the IP addresses, click Advanced… .

7	On the Advanced IP Addressing window, click Edit to change your Subnet Mask value. Add any gateways identified by your ISP in the second box. Click OK. Close all control panel windows.

To verify your IP settings with Windows 2000 or Windows XP:

1	Right-click on My Network Places and select Properties.

2	Double-click on Local Area Connection. (NOTE: If you also have an Ethernet or other connection, your DSL connection may be Local Area Connection 2.)

3	You will see the Local Area Connection Properties window. In the Connect using: box, the Intel PRO/DSL Modem should be listed.

4	Highlight Internet Protocol (TCP/IP), and click Properties.

5	View the Internet Protocol (TCP/IP) window, and verify that the correct settings are in the fields for obtaining an IP address and obtaining DNS services.


My connection to the Internet seems slow

Connections to and across the Internet can take several paths. Each path can have several potential points where traffic can back up and create a slow connection. Check the following to troubleshoot slow Internet traffic:

•	What is your connection speed? Launch Connection Manager and evaluate your Upstream and Downstream rates. Do they match the rate your telephone company says it is providing to you? For example, if your subscribed rate is for 640K downstream transfers, but you are only training at 256K downstream, there is likely a problem with your DSL service. Contact your telephone company technical support.

•	Have you added any new software to your computer that may be running at the same time as you browse the Web? If so, it may be taxing your processor and not leaving enough processing capacity for the browser.

•	Is there a specific Web site that seems to have the most noticeable slowdown? Try viewing a few other sites. It may be that the particular site is experiencing heavy traffic or is having difficulty with its connection to the Internet. Try a few different sites to see if some produce faster results than others.


My connection to the Internet was broken

Different problems might cause your connection to be dropped after successfully training and connecting to your ISP.

If the solutions here do not solve your problem, contact your ISP or telephone company technical support. When you call, have Connection Manager available. Information in these tabs can often assist support personnel as they troubleshoot your problem.


My telephone conversations are noisy

Choose from the following list of possible reasons for noisy telephone calls:

Microfilters are not installed on phones (or are incorrectly installed)

•	What are Microfilters?

Bad telephones


What are Microfilters?

One feature of DSL technology is that it allows Internet traffic to share existing telephone lines simultaneously with other voice or data traffic. "Phone lines" can carry many different types of signals at different frequencies. Voice traffic uses only a small range along the lines. Other technology (including home networking, security systems, and DSL) use different frequencies, and can therefore coexist on the lines.

However, "noise" from one technology’s signal can sometimes cross into another frequency area, and interfere with that signal. Microfilters are small fixtures that attach to your telephone lines to allow only certain types of traffic to pass through, filtering out the rest. With DSL, microfilters filter DSL noise from lines leading to telephones, fax machines, and security systems. Those devices are then able to function properly, free of unwanted static or signal interruptions.


How do I get more microfilters?

Microfilters are available in two styles: wall-mount filters for hanging wall telephones, and in-line microfilters for desk or table telephones. Identify the number of each style of microfilter that you need, and then contact your telephone company to place an order for them.

NOTE: Do not install more than 5 microfilters (combined styles) on any single telephone line. More than five microfilters on a single phone line (phone number) can create a condition called "signal attenuation", where the signals that indicate an incoming call can be weakened to the point that your telephones no longer ring.


How do I install the modem with Windows 2000 or Windows XP?

The first step in installing your modem is to make sure you have received all necessary information from your ISP. You’ll need to know whether your connection is RFC 1483 (Bridged Ethernet) or Point-to-Point Protocol over ATM (PPPoA). You may need to know the VPI and VCI numbers (the DSL "phone numbers"). If you will have a static connection to the Internet, you will need to know your IP address and Subnet Mask numbers.

Initial steps:

1	Turn off your computer.

2	Install the Intel PRO/DSL Modem in an available PCI slot.

3	Power up the system, and place your Intel PRO/DSL Modem CD in your computer’s CD-ROM drive. Windows will automatically detect the new device, and the Found New Hardware wizard will run.

4	Click Next. The device should appear as an ATM Network Controller. Choose the option to let Windows Search for a suitable driver for the device. Click Next.

5	In the next window, click the checkbox to have Windows search your CD-ROM drive for the driver.  Click Next.

6	Windows will locate the Modem Installation driver (net21w2k.inf). Click Next to install this driver.

7	On the next screen, select the type of connection required by your Internet Service Provider (Point-to-Point Protocol over ATM, or Bridged Ethernet/RFC 1483).

8	Windows will install the driver you selected. Click Finish when prompted to do so.

IP Address Configuration:

Your computer will be configured with a default DHCP (dynamic IP address) setting. If your ISP supports DHCP, simply double-click the Connection Manager connectoid in your system tray, then click the Connect button. You will be able to open your browser and pass traffic on the Internet.

To configure a static IP address with the 1483 connection protocol, follow these steps:

1	Open My Network Places, and click Network and Dial-Up Connections.

2	Double-click on the icon for your connection. (NOTE: If you created a shortcut to this connectoid in step 13 above, you may double-click the shortcut instead.)

3	Click Properties, and then select the Networking tab.

4	Verify that Internet Protocol (TCP/IP) is checked and highlighted, and click Properties.

5	Click the option button next to the field where an IP address can be entered. Enter the IP address your ISP gave you in this box.

6	Enter the DNS address(es) given to you by your ISP in the appropriate boxes.

Click OK. Your static IP address is in place and will be used during your next connection to the Internet.

Point-to-Point Protocol over ATM (PPPoA) software installation:

1	Open My Network Places, then open Network and Dial-Up Connections. Double-click on Make New Connection to start the Network Connection wizard. Click Next.

2	Select Dial-Up to the Internet, then click Next. The Internet Connection wizard will run.

6	Enter the user name and password for your account with your ISP. Click Next.

7	Enter a name for this connection. You may want to use your ISP’s name, or "DSL" to indicate that this is your DSL connection. This name will appear on an icon in your Networking and Dial-Up Connections folder. Click Next.

8	If your ISP has provided you with information about your e-mail account, you may select Yes to follow the wizard to configure that account. Otherwise, choose No, and click Next. (You can always configure e-mail accounts without going through the entire software installation process.)

9	Click Finish. An icon for this connection will appear in your Networking and Dial-Up Connections folder. Create a shortcut to this icon to your desktop for easy access.

10	Double-click the icon to bring up a connection window. Click Connect to connect to the Internet.


How do I install the microfilters?

A microfilter should be installed on each phone in your home. Use in-line microfilters to install microfilters on phones that sit on a desk or table. Use a wall-mount microfilter to install a microfilter on a wall phone.

NOTE: Do not install a microfilter on the modem line between your DSL modem and the wall jack.

To install a microfilter for a desk or table phone:

1	Refer to the Microfilter Installation Sheet that was in the box with your supplied microfilters.

2	Connect the WALL side of the in-line microfilter to the existing phone jack using one of the supplied phone cables. Connect the PHONE side of the microfilter to your phone using your existing phone cable. The installation direction does matter ¯ make sure you have each side of the microfilter pointing in the correct direction.

3	Install an in-line microfilter to phone lines connected to a fax machine, security alarm system, or other devices that connect to your phone line.

To install a microfilter on a wall-mounted phone:

1	Refer to the Microfilter Installation Sheet that was in the box with your supplied microfilters.

2	Replace your existing jack with a wall-mount microfilter, and then attach your hanging wall phone to this microfilter. The wall-mount microfilter looks like a standard wall jack, but it contains a special circuit board to eliminate noise from the DSL modem.

NOTE: Do not connect your DSL modem to the supplied wall filter, or place an in-line microfilter between your DSL modem and the wall jack. This will filter any DSL signals and your modem will not work.


How do I filter DSL if it's on a second phone number?

DSL service shares the same pair of wires as your voice telephone service. Microfilters are required to keep these signals from interfering with each other. (See "What are Microfilters?") Inside most phone cable, there are two pairs of wires. Each phone number uses only one pair, leaving the other pair available for an additional phone line. Current microfilters will only filter the first pair of wires.

If you have DSL service running over the second pair of wires (a second phone number), you may need to purchase a two-way splitter from your local electronics store. This two-way splitter will allow phones on your second line to be shielded by microfilters as well.


I installed microfilters, but still hear "noise" on my line.

Make sure that your microfilters are installed in the proper direction. If you examine the microfilter closely, you will notice that one side is labeled WALL, and the other side is labeled PHONE. Verify that you have them installed in the proper direction, with WALL closest to the wall jack, and PHONE closest to your telephone.

Other devices in your home use phone connections. These other devices need to be fitted with microfilters as well. These devices include:

•	Security systems (You may need to contact your security company.)

•	Digital TV, some cable TV, DSS and other satellite systems.

•	Analog modems

•	Fax machines


Can I choose which web browser to use?

Your Intel PRO/DSL Modem works regardless of the web browser you choose to use. You may use Microsoft Internet Explorer*, Netscape Navigator*,  or any other browser.


Is there a browser provided on the Intel CD?

The Intel CD comes with a recent version of Microsoft’s Internet Explorer*. If you don’t have a browser or if you want to upgrade to a new version, you can install the included browser from the Intel CD.

To install the browser:

1	Insert the Intel CD into your CD-ROM drive.

2	Start Windows Explorer and to go the \Updates\IE5 folder on the CD.

3	Run Ie5setup.exe.

4	Follow the prompts to complete the installation.

This software is provided for your convenience. Our customer support does not support this application. You may wish to contact your ISP or the manufacturer of the browser for support issues.


How do I configure my browser settings?

Many Web browsers will automatically detect your DSL connection when they are started. However, your ISP may give you specific instructions on how to set up your browser, depending on the browser type and version.

If you have a PPPoA connection, your browser uses Dial-Up Networking and should be configured to connect to the Internet via a modem. When you launch your browser, Dial-Up Networking will prompt you for a user name and a password.

If you have a 1483 connection (Bridged Ethernet), your browser should be configured to connect to the Internet via a Local Area Network (LAN).

Refer to your ISP for detailed instructions on establishing your browser settings. The online instructions for your browser or help files that are included with the software may also assist you with this process.


Uninstalling the Modem

Modem driver is not loaded

If the driver for the Intel® PRO/DSL Modem did not load properly during Setup, you will not be able to connect to your ISP.

Check the Windows* Device Manager to verify that your modem is installed and functioning correctly. Remember, DSL modems are actually network adapters, and will appear in Device Manager as network adapters, not as modems. Do not look for the Intel PRO/DSL Modem in the Modem session of Device Manager.

To view Windows Device Manager (Windows 95, Windows 98, and Windows ME):

1	Select Start > Settings > Control Panel.

2	Double click on the System Icon.

3	Click on the Device Manager button.

To view Windows Device Manager (Windows 2000):

1	Select Start > Settings > Control Panel.

2	Double click on the System Icon.

3	Click the Hardware Tab.

4	Click on the Device Manager button.

To view Windows Device Manager (Windows XP):

1	Select Start.

2	Right click on My Computer.

3	Select Manage.

4	Select Device Manager.

If Device Manager shows a red X or a yellow ! next to the modem, the modem is not functioning properly. Highlight the device and click the Remove button. Place the Intel PRO/DSL Modem CD in your CD drive and restart your computer. This will cause your system to detect the adapter and reinstall it. After installation, verify in Device Manager that the modem is functioning properly.

If the Intel PRO/DSL Modem does not appear under Network Adapters, look for it under Other Devices. If the modem is listed here, highlight it and click Remove. Restart your computer and reinstall the modem.


DSL Service Not Yet Activated

In some cases, you may receive your DSL modem and installation software before the telephone company and your ISP have finished setting up your account.

Look at the service installation date that was provided by your telephone company and verify that the date has passed. If it is after the date on which your service is supposed to be activated, contact your phone company for assistance.


My modem is not training

If your modem will not train, use the list of possible reasons below to isolate the problem and find a solution.

Modem driver is not loaded

DSL service not yet activated

Modem cable is not attached

Microfilter is installed on modem line

Modem cable plugged into wrong socket

Line quality does not meet minimum requirements

Bad telephones


What is "training"?

When you dial a conventional analog modem, you generally hear a lot of noise as the connection is being established. DSL modems, similar to your analog modem, will negotiate (without the nose) with the phone company equipment to establish a set of rules by which both will communicate. This is called training. Your connection data transfer rates are established during training. Training needs to happen anytime you lose connection with the telephone company’s equipment, such as when you restart your computer.

Training is a separate process from logging in to your ISP. However, they are often viewed as the same as they happen consecutively. You might be able train without being able to log in to your ISP. You will never be able to log in to your ISP without the modem first being trained.


ISP server is down

If you have previously successfully trained, connected, and passed traffic on the Internet, but now can’ t train, consider the possibility that your ISP’s server may be off-line or inaccessible. Wait a few minutes and then try again. If you are still unable to connect, contact your ISP to verify their server’s status.


Modem cable is not attached

Be sure that the supplied modem cable is firmly attached to the modem on one end, and to the phone outlet at the wall on the other end.


Microfilter is installed on modem line

Microfilters filter out all DSL traffic. If you have a microfilter installed on the same phone cable that is going to the DSL modem, you have filtered out the DSL signals and your modem will not operate. Remove the microfilter from the DSL cable, then plug the cable securely into the modem and wall outlet.

What are Microfilters?


Modem cable plugged into wrong socket

Your Intel PRO/DSL Modem has two RJ-11 sockets into which phone cables can be plugged. One socket is for the cable connecting the modem to the wall jack. This socket is labeled WALL. The second socket is a passthrough with a built-in microfilter, for you to use to plug in a telephone, fax modem, or other appliance. This socket is labeled PHONE.

If you have inadvertently plugged the cable from the wall jack into the PHONE socket, your DSL modem will not operate. Unplug the cable from the PHONE socket and plug it in to the WALL socket.


Line quality does not meet minimum requirements

Signal quality that does not meet minimum requirements may interfere with your modem’s ability to train. In some cases, you may be able to train and even pass traffic, but you may be disconnected from time to time due to poor line quality.

To check your line quality, launch Connection Manager and select the Statistics tab.

Depending on your modem type (Intel PRO/DSL 2100 Modem or Intel PRO/DSL 2200 Modem), you will see either a statistic for Line Quality, or a statistic for SNR Margin. This value will give you information about your line quality.

If you have an Intel PRO/DSL 2100 Modem, with a Line Quality statistic listed:

Look at the number for Line Quality (dB). If this number is less than 15, you may not be able to train. If it is between 15 and 18, you may be able to train, but not consistently, and you are unlikely to be able to pass traffic reliably.

If you have an Intel PRO/DSL 2200 Modem, with a SNR Margin statistic listed:

Look at the number for SNR Margin (dB). If this number is less than 6, you may not be able to train. Numbers higher than 6 are generally of no consequence unless they are very high (80-100). If you have either a very low SNR Margin number or a very high number, you probably have line quality problems.

Bad line quality may have several causes. You might be too far from the telephone company central office, or there might be "bridge taps" between you and the central office. These are problems that the telephone company must assess. Your in-home wiring may be an issue as well. Read the following tip to see if your in-home wiring might be a problem:

•	In-home wiring does not meet minimum standards

After checking your home wiring, you may need to contact the telephone company’s technical support for additional assistance. They can often verify if the bad lines are inside or outside your home, and may need to correct the problem if the bad lines are between your home and the central office.


Bad telephones

DSL shares the same set of copper wires that carry telephone calls into your home. In some cases, old or low-quality telephones can sometimes cause traffic to be generated on the copper lines, interfering with your DSL service.

If you suspect you may have such a phone, disconnect each telephone in your house one by one until the bad telephone is isolated. Replace this bad telephone.


In-home wiring does not meet standards
In-home wiring does not meet minimum standards

DSL shares the same phone lines with your existing voice calls. In many older homes, phone cables have been wired and rewired, often with different gauge wires, and often in ways that are not compatible with current standards. In many cases, the phone wires are just old or weathered. In those cases, high-frequency DSL signals are simply unable to be transmitted efficiently over the lines.

Check all of your telephone connections and junctions to ensure that they are all secure and tightly wired. Call the telephone company or a certified technician for assistance.

If you rewire, use 24-gauge wire.


My modem trains but will not log on or pass traffic

If your modem is able to train, but you cannot log on to your ISP or pass traffic on the Internet, examine the possible solutions below.

Wrong driver is installed

VPI/VCI numbers are incorrect (PPPoA)

TCP/IP settings are incorrect

Line quality does not meet minimum requirements

User name or password is incorrect (PPPoA)


Wrong driver is installed

The Intel® PRO/DSL Modem supports two methods of operation, each with its own driver. You may have a Bridged Ethernet (RFC 1483) connection, or a Point-to-Point Protocol over ATM (PPPoA) connection. The equipment your ISP has and the account type you selected when you ordered DSL service may both affect the driver type you need to use. Refer to your ISP Information Worksheet for the correct setting to choose.

To verify the type of driver you have installed, launch Connection Manager and click on the ISP Info tab. What does the Driver Type indicate? If this is not the driver type you should have, you will need to uninstall and reinstall the software.

How do I uninstall the modem or its software?


User name or password is incorrect

If you are using a PPPoA (Point-to-Point Protocol over ATM) connection to your ISP, you will be asked for a user name and a password. Both must be correct in order for you to be authenticated by your ISP so you can pass traffic on the Internet.

Verify the user name and password when you type them in the Dial-Up Networking Connection. Most user names and passwords are case-sensitive; make sure you’re using capital and lower-case characters correctly. If you are sure you are typing the user name and password correctly, contact your ISP.

NOTE: Bridged Ethernet (RFC 1483) does not require a user name or password.


VPI/VCI numbers are incorrect

Instead of using a familiar seven-digit phone number, as dial-up service to an ISP uses, DSL uses VCI/VPI (Virtual Circuit Identifier/Virtual Path Identifier) combinations to route the DSL "call" to the ISP. These numbers show up as the Phone Number when using a PPPoA connection type; for example, 1,1. Your telephone company assigns these numbers, and your ISP may be able to provide them to you as well.

To verify your VPI/VCI numbers, look at the "phone number" in Dial-Up Networking. Make sure the numbers listed are the ones you were given by the telephone company or your ISP. Make sure they are in the correct format (1,1), with no other spaces or characters present. Area codes or call waiting codes are not necessary.


TCP/IP settings are incorrect

The Internet and DSL use TCP/IP as the protocol to transmit data across the World Wide Web. Your IP address identifies your location on the Internet. You must have an IP address and subnet mask to be able to pass traffic on the Internet.

See How do I check or change my IP address settings? for help verifying or changing your IP addresses.

If you selected the wrong method or input the wrong numbers, you will need to change the numbers to the ones provided by your ISP.


My modem trains, but drops the connection

In some instances, you may be able to train, and even pass traffic on the Internet, but without warning your connection will be dropped. Consider the possible reasons for this situation below.

Connection drops when phone is picked up

Line quality does not meet minimum requirements

Bad telephones


Connection drops when phone is picked up

If your connection drops when your telephone rings or is picked up, one or more of the following issues may be responsible. Explore each possibility to troubleshoot the problem.

Bad telephones

Microfilters are not installed correctly, or at all


Modem is not in a bus mastering slot

The Intel® PRO/DSL Modem must be in a bus mastering PCI slot. Some older computers have PCI slots that are not bus mastering, or bus mastering may have been disabled via the computer’s BIOS.

Try putting the modem in a different PCI slot and restart your computer.

You may need to check your system’s BIOS and ensure that any bus mastering options are enabled for the PCI slot in which the modem is installed. Consult your computer documentation for information about accessing the BIOS.


Modem is not installed

In order to successfully install the software for your Intel® PRO/DSL modem, the modem card must be installed in your system. Setup will not run unless the card is in place in an available PCI slot. Follow the instructions in the Quick Installation Guide to install the modem in your computer.


The modem is not seated in the PCI slot

If you are following the instructions in the Quick Installation Guide and your modem cannot be detected, check to ensure that it is seated correctly in the PCI slot.

When you insert the modem into the slot, you should hear a snap as the modem seats firmly into the slot.


Uninstalling the Modem - Windows 95 or 98
Uninstalling the Modem - Windows 95, 98, and Millennium Edition (ME)

In Windows, click Start > Programs > Intel® PRO/DSL Modem > Uninstall

The software will be uninstalled.

If you want to completely remove the modem from your system, shut down your computer completely and remove the modem card from the slot. If you do not remove the modem from your machine, Windows will detect it the next time you restart your computer, and the Add New Hardware wizard will run to reinstall the modem.


Glossary
Glossary of DSL Terms

ADSL

Asymmetric Digital Subscriber Line. A high-speed transmission technology using existing twisted pair lines that allow simultaneous phone conversations and Internet access. Downstream rates are usually greater than upstream rates.

ATM

Asynchronous Transfer Mode. A connection-oriented switching technology which uses fixed-length cells. Phone companies commonly use ATM to transfer data around the Internet.

BPS

Bits per second. Indicates the speed at which data bits are transferred.

Bridged Ethernet

Also referred to as RFC 1483, this protocol is used by some ISPs to provide access to their computers and to the Internet. Your will need to find out from your ISP if you will use Bridged Ethernet or PPPoA for your DSL service.

CAP

Carrierless Amplitude & Phase Modulation. A transmission technology used to implement a DSL connection. Another technology commonly used instead of CAP is DMT. CAP and DMT are not compatible with each other.

CLEC

Competitive Local Exchange Carrier. Post-deregulation CO telephone carriers.

CO

Central Office. This is where the telephone company’s infrastructure equipment is located.

CPE

Customer Premises Equipment. Your DSL modem is considered to be CPE. It resides at your premises and connects the customer (you) to the phone company network.

DHCP

Dynamic Host Configuration Protocol. A TCP/IP protocol that generates automatic/dynamic IP addresses. If your computer is configured for DHCP, your ISP will automatically assign you an IP address each time you log on to the network.

DMT

Discrete Multi-Tone. DSL technology that uses DSLs to code information for use in a DSL network. CAP is another technology that performs the same function. CAP and DMT are not compatible with each other.

DNS

Domain Name Server. Servers on the Internet or at the ISP that maintain associations between IP addresses and domain names. DNS allows the user to type in a name (www.intel.com) instead of a numeric IP address to reach Internet resources.

Downstream

Refers to the transmission direction from the CO to the consumer. Usually measured in Kbps.

DSL

Digital Subscriber Line. The high speed local-loop connection between the CO and the CPE. DSL provides concurrent phone use and Internet access over the same pair of wires, using only one telephone line (one phone number).

DSLAM

Digital Subscriber Line Access Multiplexer. This is the equipment installed at the phone company’s CO that allows for ADSL. It splits your regular voice traffic from data traffic. Your CO must have the proper DSLAM for you to get DSL.

DSP

Digital Signal Processor. A microprocessor ("chip") on the modem that handles line signaling.

DUN

Dial-Up Networking. This is a service used to connect to the Internet with a PPPoA connection protocol.

Dynamic IP Address

This is a service provided by your ISP that automatically assigns you a random IP address from its pool of available addresses using DHCP. Your address may change each time you log on to the network. If you are hosting a Web server, you should use a static address rather than a dynamic address.

FAQ

Frequently Asked Questions.

G.Lite

G.Lite is the informal name of a method to deploy DSL services to home and small business users. Also known as Universal ADSL, G.Lite makes it possible to have Internet connections to home and business computers at up to 1.5 Mbps (millions of bits per second) over regular phone lines.

ILEC

Incumbent Local Exchange Carrier. Refers to the primary existing CO carrier. The ILECs were established before deregulation.

IP

Internet Protocol. The networking protocol used as the primary method for transferring data over the Internet. It is also used in many LANs.

ISP

Internet Service Provider. A company that provides you with access to the Internet. In some instances, the ISP is a separate entity from the telephone company. In addition to the phone company’s DSL service, you must also have an account with an ISP that supports DSL.

Kbps

Kilobits per second. One K is 1,024 bits.

Last Mile

Also referred to as "local loop". This is the distance between the CPE and the CO. With current DSL technology, this distance cannot be longer than 18,000 feet. Acceptable distance varies with line conditions.

LAN

Local Area Network. If you are using a Bridged Ethernet connection, your connection to the Internet is via a LAN.

Local Loop

The distance between the CO and the customer’s premises.

Mail Server

Mail servers are located at your ISP and hold and route your e-mail until you access it. There are both incoming and outgoing mail servers at most ISPs. Find out from your ISP how to configure your e-mail software to access their mail servers.

Mbps

Megabits per second. One megabit is 1,048,576 bits.

Microfilter

Microfilters are devices that are connected between your telephone and the phone jack. Because DSL allows voice and data traffic to share the same pair of wires, microfilters are needed to keep the signals from interfering with each other. If you hear excess "noise" on your telephones after DSL service has been activated, make sure that your microfilters are installed. Do NOT install microfilters on the modem cable that extends from your DSL modem to the wall jack. If you do, your DSL service will not work.

Name Server

Name servers translate names from one form into another. For example, the Internet relies on Domain Name Servers (DNS) that translate domain names (for example, www.intel.com) into IP addresses (for example, 255.255.255.0).

News Server

News servers are located at the ISP. They hold and route messages from Internet newsgroups. You can subscribe to newsgroups to read and reply to messages. Contact your ISP for more information about using their news server.

NIC

Network Interface Card. A board that often resides inside the computer that connects that machine to a network. The Intel® PRO/DSL Modem is a NIC.

NID

Network Interface Device. This is the box that attaches to the customer’s house at the point of demarcation (where your phone service enters the house).

PVC

Permanent Virtual Circuit. A PVC is the combination of the VPI/VCI pair. This pair of numbers is used to identify a route through an ATM/ADSL network.

POTS

Plain Old Telephone Service. Refers to the standard telephone service used in most homes.

POTS Splitter

A device that separates the POTS information from the DSL information. Because DSL and POTS share the same line, it is necessary to keep the two signals from interfering with each other. Sometimes a POTS splitter will be used; in most instances, you will use microfilters.

PPPoA

Point-to-Point Protocol over ATM. A protocol that some ISPs will use to give access to their computers and to the Internet. Find out from your ISP if you will be using PPPoA or Bridged Ethernet.

Router

A device that routes LAN traffic through the network.

SNR

Signal-to-Noise Ratio.

Static IP Address

An IP address that has been permanently assigned to you by your ISP. If you are hosting a Web server, you should have a static IP address.

TCP/IP

Transmission Control Protocol/Internet Protocol. The most widely used protocol suite of the World Wide Web, TCP/IP is the basic communications process that directs how and where data is sent.

Train

With DSL, the CPE equipment and CO equipment need to negotiate to establish a connection across which data can be transferred. This negotiation process is called training. When the CPE and CO equipment successfully transmit data to each other, they are considered trained. Your modem must be trained before you can pass any traffic or browse the Internet. Training also establishes your data transfer rate.

Upstream

Refers to the transmission speed from your modem to the CO. Upstream rates are typically slower than downstream rates in ADSL.

VCI

Virtual Channel Identifier. This number is part of the PVC. It establishes your "channel" through the telephone company equipment.

VPI

Virtual Path Identifier. This is part of the PVC. The VPI, combined with the VCI, forms your "channel" through the telephone company equipment.
