Important Information about V.92 Modems
With V.92, as with the earlier V.90 standard, your connection speed
depends 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.
Your V.92 modem includes the following capabilities.
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 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:
1.
Contact your ISP and get the phone number of a V.92 connection to the ISP.
2.
Check our web site for news of any V.92 updates. If an update is
available, follow the directions below for upgrading your modem.
Note:
12 USB Modem Installation Guide
If you want to manually change the way your modem connects, please consult the AT command tables beginning on
page 25 in the
Troubleshooting
section.
Modem Upgrades
Your modem’s software, or “ firmware,” can be easily upgraded. This
is useful for code updates and feature enhancements. To upgrade
your modem’s firmware, you simply download the new firmware files
from our Web site and then run a program we provide. Before calling
your first V.92 site, we strongly suggest that you download the latest
firmware.
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 modem.
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 modem 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 included
with your modem package, which contains 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 recog-
nize your new modem; refer to the

section, page
Making the Most of the Fax Features
Your faxmodem includes software on the enclosed CD that enables
you to send, receive, and schedule faxes. The software will also let
you set up fax-back, sometimes called fax-on-demand, and issue fax
broadcasts.
If you use your faxmodem for receiving faxes, keep in mind the following:
Communicating with your Faxmodem 15
•
Your computer must be running, and the communications soft-
ware must be active.
•
If you want to connect to your online service or ISP, you must exit
the communication software first. While you are on line, you cannot receive calls or faxes.
•
Some computers have a power saving option that stops the hard
drive from spinning after a period of inactivity. If a call comes in,
it may fail to connect while the hard drive restarts and activates
the software. If this happens, you should deactivate the feature
of your power saving option that stops the hard drive. See your
computer's documentation for details.
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:
If you are asked to select the “ modem type” from a menu, and you
don’t see this modem listed by name, select the most descriptive
name such as

In the dialing directory, set all entries to the highest possible baud
rate, if your software and serial port support these speeds (do not go
over 115,200 bps). All communications between the computer and
the faxmodem take place at this higher speed, independent of the
modem-to-modem speed.

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 AT command strings for all commands sent
to the modem. This is transparent to you—the software does this in
the background without you being aware of it.
It is sometimes necessary, however, to add other AT commands to
initialization strings. You can find a table of AT commands on the
World W ide Web at
AT Command Sets
on
www.modems.com
.
If your software suggests an initialization string for this modem, you
should use it. If your software does not list this modem and no initialization string is suggested, use the following:
Your telephone service may include Call Waiting that you can temporarily suspend by using your phone to dial a special code. (For example, in the U.S., you can disable call waiting by adding *70 to your
dialing prefix; please check with your local phone company for the
correct code for your area.) You can include that code, followed by a
comma, in the dial string or dial prefix in your software.
. Click
AT &F
Reference
.
and then
If your software does not handle AT commands automatically, it
should provide a place to enter AT commands in its setup menus.
However, in some cases you may need to enter AT commands directly to the faxmodem. You must do so from a data program’s terminal mode.
Refer to the
Troubleshooting
section for more tips about AT com-
mands.
Using Terminal Mode to Enter AT Commands
Start your data communications program.

Change to terminal mode (also called command, local, direct, or
dumb mode). Check your software documentation for additional instructions.
Type AT plus the command you need and press
Enter
. You will see
an OK response.
When you finish, you can return to the data communications program’s standard user interface. See the software program’s documentation if you need help.
To return to the factory default settings for the modem, in terminal
mode, type
AT &F
and press
Enter
.
Using Video
Your faxmodem supports video applications through the V.80 standard protocol so that it can be used for high-quality modem-tomodem videoconferencing. The modem is compatible with H.324
point-to-point and H.323 Internet video conferencing standards. To
send videos, you need a camera and video software.

Other Troubleshooting Tips
Problem:Your modem seems to install under Windows, but
Windows cannot find it later.
Solution
:
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.
Problem: The software cannot find the modem and the modem
does not respond to AT commands. (The following
comment applies to many other problems as well.)
Solution
:
The most common problem 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. Make sure
that the software’s COM port setting matches the modem’s COM port setting. From the Windows Toolbar, go

to

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 soundcard.
:
Problem
You type an AT command line in a terminal application and press Enter, but your modem fails to execute the command line. Or there was no response after executing a command.
Solution
22 USB Modem Installation Guide
:
Be sure you type AT at the beginning of the command
line.
Make sure the communications software is configured
for the same COM port as your modem.
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
ATE1Q0
and press
Enter
.
Problem
Solution:
:
The modem speaker volume is too low or too high.
Your modem has a small speaker on board that provides
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, make
sure the speaker is enabled and set to a comfortable
volume.
If the software does not have speaker settings, add one
of the AT commands listed below to the initialization
string:
L1
for low volume
L2
for medium volume
L3
for highest volume
M0
to turn the speaker off entirely
For example, if you want the volume low and the software uses the initialization string
AT &F
, change it to
AT &F L1
.
Troubleshooting 23
Problem:The modem does not automatically dial a call when
you send a Dial command.
Solution
Problem
Solution
:
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
terminal mode.
:
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.

lecting it as a prefix, in the software’s dialing directory.
Depending on your service, you may not be able to disable Call Waiting for incoming calls. If your incoming
data calls are frequently disrupted by Call Waiting, you
should consider dropping the service or installing a separate phone line without Call Waiting.
Troubleshooting 27
Problem: Your modem does not make a connection.
Solution:
If your modem places calls but never connects, make
sure you are dialing the right number and that the remote
modem is turned on.
Problem: You receive bursts of errors occasionally, but oth-
erwise data quality is good.
Solution:
The connection may have been established on poorquality or noisy telephone lines. Hang up and place the
call again to try to obtain a better connection.
Someone may be picking up an extension connected to
the line that your modem is using. If your modem is
sharing a telephone line with other telephones, inform
the other users when you will be making a data call, or
install a separate line dedicated to data calls.
Your telephone line may have a Call Waiting feature and
a call is being received. See the Call Waiting discussion
above.
Problem: Random errors occur or data is missing in transmit-
ted data.
Solution:
Use the MNP or V.42 protocol if the remote modem supports one of these protocols. See the table on page 26
for more information.
Select a lower baud rate in your communications software and place the call again.
28 USB Modem Installation Guide
If both modems are using the MNP or V.42 protocol, the
only way this can occur is if your modem and communications software are not using the appropriate flow control. Configure your communications software for
RTS/CTS
(hardware) flow control. Your computer will
now pause for the transmission to be stored.
Problem: Modem performance seems sluggish.
Solution:
If you are connected to the Internet, there may be a lot of
“ traffic” at the W eb sites you are visiting. Other possible
causes are lack of sufficient memory in your computer
(16 megabytes of RAM required) or a slow processor
(you need a Pentium® 133 or faster, or equivalent).
Problem: Data appears garbled on the screen.
Solution:
Your communications software character set-up (start
bit, data bits, stop bits, and parity bit) does not match
that of the remote system. Check your settings against
those used by the remote system and make sure they
match. Pay particular attention to the parity setting, as
this is the most common difference among systems. You
should normally use 8 data bits, NO parity, and 1 stop bit
8, NONE, 1
(
bits, EVEN parity, and 1 stop bit (
or
8N1
). Another common setting is 7 data
7, EVEN, 1
or
7E1
).
Problem: You encounter communications problems with your
modem.
Solution:
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.
