2.4 Hardware Configuration (Plug and Play)
Your modem is configured using the Plug and
Play (PnP) capabilities of your computer. Plug and
Play is a set of specifications that define the ability for
the computer hardware and operating system to automatically configure all compliant devices that are installed, relieving the user of the need to determine
which addresses and interrupts to use for each device.
Consult your PC's owner's manual to determine if it is
PnP Revision 1.0a compliant. You most likely have a
Plug and Play Revision 1.0a compliant system if it was
purchased after June 1994 or if the BIOS is dated after
June 1994.
Proceed to one of the following sections, depending on your system's configuration:
• Section 2.4.1 if you are running Windows
95 (with or without a Plug and Play PC)
• Section 2.4.2 if you are running Windows
3.1x or DOS on a PnP-compliant PC.
2.4.1Configuring in Windows 95
The version of Windows 95 you have will determine which set of dialog boxes is presented to you
when installing the modem in Windows 95. Proceed to
one of the following sections, depending on your
Windows 95's diaglog box:
• Section 2.4.1.1 when Windows 95 starts for
the first time after card installation, it
detects the modem and it displays the New
Hardware Found dialog box
• Section 2.4.1.2 when Windows 95 starts for
the first time after card installation, it
detects the modem and it displays the
Update Device Driver Wizard.
3
2.4.1.1 Windows 95 Release 4.00.950
When Windows 95 starts for the first time after
card installation, it detects the modem and displays the
New Hardware Found dialog box.
Under New Hardware Found, when asked to
“Select which driver you want to install for your new
hardware,” click on “Driver from disk provided by
hardware manufacturer.” Click “OK.”
The Install From Disk dialog box now instructs
you to “Insert the manufacturer's installation disk into
the drive selected, and then click OK.” Insert the
modem's driver diskette into the disk drive and type A:\
(or B:\ if inserted in drive B) in the “Copy manufacturer's
files from:” box. Click “OK.”
Windows 95 may request its own installation
disks or CD-ROM for some files. Insert the Windows
95 disks or CD-ROM as required. When all necessary
files are copied, the modem is configured. Windows 95
will assign the modem a COM port and IRQ line.
Proceed to Section 2.5.
2.4.1.2 Windows 95 Release 4.00.950 B
When Windows 95 starts for the first time after
card installation, it detects the modem and displays the
Update Device Driver Wizard.
Insert the driver disk into the disk drive and click
“Next.” Windows will find the driver on the driver disk.
Click “Finish. Windows 95 may request its own installation disks or CD for some files. Insert the Windows 95
disks or CD as required.
Windows will now find a second device on the
modem. Make sure that the driver disk is still in the disk
drive and click “Next.” Windows will find the second
driver. Click “Finish” to complete the installation.
When all necessary files are copied, the modem
is configured. Windows 95 will assign the modem a
COM port and IRQ line. Proceed to Section 2.5.

2.4.2Configuring in a Plug and Play System with-
out Windows 95
When this modem is installed in a Plug and Play
system without Windows 95, the computer's BIOS will
assign a COM port and IRQ line to the modem.
Proceed to Section 2.5, Software Installation/
Configuration.
2.5 Software Installation and Configuration
You are now ready to install and configure the
communication software. Refer to your software manual
for installation procedures.
We suggest the following communication parameters when you first use your data communication
software. Consult the software manual for information
on using these and other parameters/features.
57,600 bps; 8 data bits; no parity; 1 stop bit;
RTS/CTS flow control set to “on;” initialization
string: AT&F
We suggest that a “Generic Class 1” or “Generic Class 2” modem type should be selected in your
fax software, and a “Lucent” modem type should be
selected in your Voice software.
Note that your software must be configured to
communicate with the modem on the same COM port
and IRQ line used by the modem.
2.6 Using the Fax, Voice, SVD, and
Speakerphone Capabilities of the
Modem
Your modem has built-in advanced FAX, Voice,
SVD, and Full Duplex Speakerphone functions. Please
consult your FAX/Voice/SVD/Speakerphone software
manual about procedures on using these features.
Speakerphone functions require a correctly configured sound card with attached microphone and
speaker.
Voice functions include recording and playback
of voice prompts (files). You may record or playback
voice with your modem by attaching a telephone to the
5
RJ-11 jack marked “PHONE” or by attaching a microphone to the MIC jack and a speaker to the SPK jack
of your sound card. Follow instructions in the FAX/
Voice/Speakerphone software on recording and playback of voice prompts.
2.7 Testing Your Modem After Installation
In order to test your modem you should be
familiar with your communication software. Load and
set up your communication software and enter into
“terminal mode.” Make sure that the COM Port and
IRQ settings of the modem match the software. Type
AT on your terminal screen and press ENTER. You
may see “AT”, “AATT” or nothing on the screen. In any
case, the modem should respond with an OK or 0. If it
does not, either the modem may not have been installed properly or the software has not been properly
configured. Review Sections 2.2-2.5 and be certain
that the modem and the software have been properly
installed. If required, refer to Section 6 for additional
troubleshooting information.
2.8 Using Your Modem
The communication software included with your
modem product provides a user friendly interface to
access the fax, voice and data functions of your
modem.
your communication needs
when you need to access the modem manually via
modem commands. Read Section 3 for a summary
description of the modem command set before manually accessing the modem. You may want to read the
software manual first, however, as the software may
already provide a user friendly method of accessing
the functions you need (i.e. dialing or answering calls).
This software should be sufficient for all of
. There may be times
2.9 Where To Go From Here
You should familiarize yourself with the functions
available from the included software by reading its
manual. You will be accessing most, if not all, of the
modem's functions from this software. You may also
use any other commercially available communication
software with the modem. Read Section 3 only if you
6
are interested in accessing the modem manually, and
not through the included software. Section 4 and 5
contain reference material, and can be skipped. If you
have difficulties getting your modem to work, read
Section 6 - Troubleshooting to find answers to commonly asked questions and problems.
Section Three - AT Command Set
3.1 Executing Commands
Commands are accepted by the modem while it
is in Command Mode. Your modem is automatically in
Command Mode until you dial a number and establish
a connection. Commands may be sent to your modem
from a PC running communication software or any
other terminal devices.
Your modem is capable of data communication
at rates of: 300, 1200, 2400, 4800, 9600, 14400,
19200, 28800, 38400, 57600, and 115200 bps. Make
sure your COM port baud rate settings in your communications software is set to one of the above speeds.
3.2 Command Structure
All commands sent to the modem must begin
with AT and end with ENTER. All commands may be
typed in either upper or lower case, but not mixed. To
make the command line more readable, spaces may
be inserted between commands. If you omit a parameter from a command that requires one, it is just like
specifying a parameter of 0. Example:
ATH [ENTER]
This command causes your modem to hang up.
3.3 Basic AT Commands

Section Four - S Registers
Your modem has 28 registers, designated S0
through S92. Table 4-1 shows the registers, their
functions, and their default values. Some registers can
have their values changed by commands. If you use a
command to change a register value, the command
remains in effect until you turn off or reset your modem.
Your modem then reverts to the operating characteristics specified in its non-volatile memory. Refer to
Section 3 for information on how to use the AT commands to manipulate the S registers.

Section Six - Troubleshooting
This section describes some of the common
problems you may encounter while using your modem.
If you can not resolve your difficulty after reading this
chapter, contact your dealer or vendor for assistance.
Modem does not respond to commands.
1. Make sure the communication software is configured
15
to “talk” to the modem on the correct COM port and IRQ setting (same COM port and IRQ setting as the modem). Your communication software must know which address your modem is using in the system in order to pass data to it. Similarly, IRQ settings must be set correctly to receive data from the modem.
2.Make sure that your modem is initialized correctly. Your modem may have been initialized to not display responses. You may factory-reset the modem by issuing AT&F and press ENTER. The factory default allows the modem to display responses after a command has been executed.
Modem does not dial.
1.Make sure the modem is connected to a working phone line. Replace the modem with a working phone to ensure that the phone line is working.
2.Make sure the phone line is connected to the jack marked “LINE.” Incorrect connection prevents the modem from operating properly. Refer to Section 2.3 for modem connection instructions.
Modem dials but does not connect.
1.Make sure the IRQ setting is identical on both the modem and the software. Modem and software must be configured identically.
2.Make sure the phone line is working properly. Replace the modem with a regular phone and dial the number. If the line sounds noisy, you may have difficulty connecting to the remote device.
Modem makes a connection but no data appears on your screen.
1.Make sure the correct data format (data bits, stop bits, and parity bits) and flow control (RTS/CTS) are being used.
2.Make sure the correct terminal emulation mode is being used (see communication software manual).
High pitch tone is heard whenever you answer the phone.
1.Make sure Auto-Answer is turned off. Your modem is factory configured to NOT auto-answer. Issue AT&F to factory reset your modem.
Modem experiences errors while communicating with a remote modem.
1.Make sure the DTE speed is the same as the modem connection speed when in Direct Mode.
2.Make sure the remote system and your modem use the same communication parameters (speed, parity, etc.).
3.Make sure RTS/CTS hardware flow control is enabled and XON/XOFF software flow control is disabled in the communication software.
4.Make sure the data speed is not faster than your computer's capability. Most IBM compatibles are capable of 19,200 bps under DOS and Windows 3.X. Operating at higher speeds under Windows requires a 486 or faster CPU or Windows 95.
Modem experiences bursts of errors or suddenly disconnects while communicating with a remote modem.
1.Make sure Call Waiting is turned off.
2. Make sure the phone line does not exhibit excess
noise.
