Important Information for Owners of V.92 Modems

With V.92, as with the earlier V.90 standard, your connection speed will depend on your phone line and your Internet Service Provider (ISP). To enhance compatibility, this modem automatically detects whether to use V.92, V.90, or a slower mode when it connects to your ISP.

QuickConnect:

• A V.92 modem remembers the line conditions of the last number called, and uses this information to try to reduce connection times.

Modem-on-Hold:

• You have the option of receiving voice calls while online. You can answer the call and put your Internet session on hold if your ISP supports this capability and you have Call Waiting service compatible with the modem.

Faster Upload Speeds:

• Upload speeds may be increased, from 33.6K bps to a maximum of 48K bps. (Actual rates will vary, depending on line conditions.)

V.44 Data Compression:

• The V.44 standard lets you browse the Web and transfer data at higher speeds.

To make the most of your V.92 modem, follow these steps:

Contact your ISP and ask for the phone number of a V.92 connection to the ISP.

Check our web site for news of any V.92 updates. If an update is available, follow the directions below for upgrading your modem.

12 Modem User Guide

Modem Upgrades

Your modem’s software, or “firmware,” can be easily upgraded. This is useful for code updates and feature upgrades. To upgrade your modem’s firmware, you simply download the new firmware files and then run a program we provide. Because V.92 technology is new, you may want to download the latest firmware before calling your first V.92 site. Upgrades are available from our Web site.

We also suggest that you register your modem with us so that we can notify you via e-mail when new firmware releases are available.

Communicating with your Faxmodem

The faxing and communications software that came with your faxmodem sets itself up automatically and takes care of sending any necessary commands to the faxmodem.

You should read this section, however, if you want to learn some general facts about how software works with your faxmodem, or if you intend to use your new faxmodem with other software.

Accessing the Internet

To access the Internet and the World Wide Web, you need an online service such as America Online (AOL) or CompuServe, or an Internet Service Provider (ISP). The best place to start is the CD(s) included with your modem package, which contains Internet and online services for you to try.

Online services provide installation software that makes signing up almost automatic. ISPs typically supply or suggest the browser software needed to access their service. They also provide additional instructions and software for setting up your account.

Note:

You may need to redirect your application software to recognize your new modem; refer to the page 19, if you need assistance.

Communication Setup Options

If you run into configuration difficulties with your communication software, it may be helpful to read the following section.

In setting up some older software programs, you may be asked to enter certain information. Most programs have default settings that are correct for use with this modem, and there is no need to change them. However you should be aware of the following items:

Initialization Strings and AT Commands

An initialization string is a group of AT command settings that is sent to the faxmodem as soon as you start up the software. The software determines which commands should be included in the initialization string, based on the device you select during installation. The commands remain in effect throughout the communications session, unless the software sends other commands to override them.

The software uses other sent to the modem. This is transparent to you—the software does this in the background without you having to be aware of it.

It is sometimes necessary, however, to add other to initialization strings. You can find a table of the World Wide Web at

Other Troubleshooting Tips

Your modem seems to install under Windows, but Windows cannot find it later…

If your computer has a built-in modem on the motherboard, Windows may reinstall it the next time you start up. Consult your computer’s documentation or call your computer’s manufacturer to get instructions on how to disable the built-in modem.

The software cannot find the modem and the modem does not respond to AT commands…

The most common error with modems is that the communications software is not configured for the same COM port as the modem. Check which COM port the modem is using and ensure

Troubleshooting 21

that the software’s COM port setting matches the modem’s COM port setting.

Another problem is that COM port resources may be in use by another device. Make sure that the COM port resources used by the modem are not being used by any other device, such as a sound card.

In terminal mode, be sure you type AT at the beginning of the command line.

Be sure your modem is not in data mode when you type the command. Use the escape character sequence to switch to terminal mode. (The default escape sequence is to wait at least one second, type

+++

, and wait another second or more.)

If you typed a command but did not receive an OK response from your modem: The E0 and Q1 commands may be in effect, disabling echo and responses. Verify this with the &V command. To enable echo and responses type

AT E1 Q0

and hit

Enter

You encounter communications problems with your modem…

Check that your communications software has been set up properly. Recheck the initialization string and dial string specified in your software manual.

Memory-resident programs can cause a variety of problems. Try starting up your computer without them. Programs that can cause problems include antivirus programs and screen savers.

The modem speaker volume is too low or too high…

Your modem has a small speaker on its board that gives you audible feedback of dial tones and remote connection signals (“handshaking”). This is not the same as the speaker that you may have connected to your sound card.

If the software allows you to control the volume of the on-board speaker, make sure the speaker is enabled and set to a comfortable volume.

If the software does not have speaker settings, add one of the

commands listed below to the initialization string:

22 Modem User Guide

L1 L2 L3 M0 M1

for low volume for medium volume

for highest volume to turn the speaker off completely to turn the speaker back on

For example, if you want the volume low and the software uses the initialization string

AT &F

, change it to

AT &F L1

The modem does not automatically dial a call when you send a Dial command…

Make sure the modem speaker is turned on in your software so that you can hear dialing sounds. Also make sure that the phone line is plugged in.

Make sure that you are dialing a valid phone number, including any required dial prefixes.

If you are using tone dialing on a line that requires pulse dialing, the line may not be able to accept tone-dialed calls. Select Pulse dialing in your software or make sure software dialing prefix is

ATDP

(for pulse dialing).

Make sure your communications software and modem are configured for the same COM port.

Make sure your modem has hung up from the previous call. Select

Hang Up

in your software; or type

ATH

in terminal mode.

Your modem disconnects while communicating with a remote system…

The remote system has hung up. You need to reconnect. The telephone line disrupted your call. If your telephone service

includes Call Waiting, turn it off if possible before making modem calls.

Depending on your service, you may not be able to disable Call Waiting for incoming calls. If your modem often receives data calls and communications are frequently disrupted by Call Waiting, you should consider dropping the service or installing a separate phone line without Call Waiting.

Troubleshooting 23

Someone may be picking up an extension connected to the line that your modem is using. If the modem is sharing a telephone line with other telephones, inform the other users when you will be making a data call.

Your modem does not make a connection…

If your modem places calls but never makes a connection, make sure you are dialing the right number. The remote modem may be turned off.

The modem can connect to some modems, but not to others…

A remote modem does not respond because of the extended negotiation process by which modems determine the best common connection between them. If this is the case, you may have to disable part or all of the negotiation process. In the following table, “protocol” means error correction and data compression.

Notes:

Some software allows these commands to be added to

the list of dial prefixes or the initialization string.

When the protocol is forced, the modem will not attempt

to connect at other protocols if it cannot connect at the

forced protocol. It will try to connect at the fastest speed

available within the forced protocol.

There are other configurations that can be forced as well. If you need to select a particular configuration, use the AT command strings shown below. You can always return to the modem’s default configuration by typing
