bis/MNP 5 (Microcom Networking Protocol Class 5). Each mode has its
own unique AT command set. Additionally, the modem provides special
modes of operation for power management.

DATA MODE

In the data mode, the modem allows data to be received at speed up to 56
kbps. Taking advantage of the PSTN, which is primarily digital except for
the central office local loop, this modem is ideal for remote access
applications such as Internet Service Provider, On-line service, or corporate
site. As a client modem, data can be sent at speed up to 31.2 kbps.

As a V.34 data modem, the modem operates at line speeds up to 33.6 kbps.
Error correction and data compression maximize data transfer integrity and
boost average data throughput up to 115.2 kbps.

10

It implements all data rates and modulation schemes for IT-U (formally
CCITT) standards V.34, V.32bis, V.32, V.22bis, V.22, V.21, Bell 212A,
and Bell 103. The INTEL / AMBIENT MD5662 implements a standard
data mode AT command set. This is compatible with any communication
application software that supports the Hayes AT command set.

V.42/MNP 2-4 AND V.42 BIS/MNP5 MODES

The modem supports error correction(V.42/MNP 2-4) and data compression
(V.42 bis/MNP 5). Error correction ensures error-free data transfer. Data
compression substantially increases the modem data throughput over the
basic data rate. Depending on the data stream, MNP 5 may provide up to 2­to-1 compression. Alternately, CCITT V.42 bis may provide up to 4:1
compression.

FAX MODE

In the fax mode, the modem operate at up to 14,400 bps (transmit and
receive) and implement all the data rates and modulation schemes for
CCITT standards V.17, V.29, V.27ter, and V.21 channel 2. The
Cirrus/Ambient chipset implement a standard fax command set compatible
with any communication application software that supports EIA/TIA-578
Fax Class 1 standards.

VOICE/AUDIO MODE

In voice/audio mode, enhanced 2-bit or 4-bit per sample ADPCM coding
and decoding at 7200Hz sample rate allows efficient digital storage of
voice/audio. This mode supports digital telephone answering machine,
voice annotation, and audio recording and playback application.

TELEPHONE-EMULATION MODE

This mode allows a microphone-speaker and modem to be used as a
complete telephone. In Telephone emulation mode, the received data from
the microphone interface is looped back to the SAFE analog transmit pins.
In voice mode, the message record and playback abilities are accessed by the
extended AT command set.

11

VIDEOCONFERENCING (V.80) SUPPORT

The Communicator V.90 supports IT-U V.80 recommendations. This
feature ensures compatibility with host-based H.324 videoconferencing
application software. The INTEL / AMBIENT MD56xx chipsets support
both transparent and framed submodes of the V.80 synchronous access
mode.

POWER MANAGEMENT MODES

The Cirrus/Ambient chipset provide sleep mode to reduce power
consumption when the modem inactive. In operational mode, the modem
chipset is fully powered and is either communicating with the host and/or
another modem or is performing internal processing.

The modem is considered to be in an inactive state when:

1. No internal processing is being performed.

2. No activity occurs between the host and the modem within a specific
time.

3. The modem is on-hook.

The mode exits sleep mode whenever the host writes the modem or when a
ring signal is detected.

CALLER ID

Caller ID is a service that allows the called party know the caller’s
telephone number before the call is answered. The information transmitted
to the called party via Caller ID includes the call date, the call time, and the
call number. This service is not available everywhere due to Central Office
telephone equipment limitations and legal prohibition in some locations.
Subscription for this service is usually available at a small monthly fee.

CHAPTER 4 TROUBLE SHOOTING

Modem Basic

This chapter will address some basic terminology associated with your
modem and with your communications software.

MODEM

Modem is an abbreviation of Modulator and DEModulator. It is use for
computer communication. Modem translates computer data to analog signal
(modulation) that can travels through the telephone network and reaches
the other modem. The remote modem translates the analog signal received
back to data (demodulation) and sends to the receiving end computer.

FAX MODEM

Most modem device designed to have the fax transmitting (or and)
receiving function(s).

VOICE MODEM

Modem with digitized voice capability can digitize the incoming voice
message and the computer can store it as a file. The voice modem can also
playback a recorded digital voice message either locally or to the line as an
announcement.

DTE / DCE

DTE stands for Data Terminal Equipment and DCE stands for Data
Communication Equipment. The Computer or terminal is the DTE and the
modem is the DCE.

DSP

Digital Signal Processor. It performs all digital signal processing functions
for the chipset, such as modulation schemes and modem handshakes.

UART

UART (Universal Asynchronous Receiver Transmitter) is the device used in
DTE or DCE for asynchronous data receiving and transmitting. The normal
UART device used in PC is NS16450. For high-speed serial data receiving

35

(38500 bps and up), the PC may not be fast enough and data may become
lost. In this case, a UART with data buffer is need such as NS16550A.

NVRAM

NVRAM(Non-Volatile RAM) is a device to store the DCE configuration.
Upon powering-up, the modem defaults to the configuration specified in the
NVRAM or to the factory default (if the NVRAM was not installed). DCE
configuration can be changed and stored by DTE in the NVRAM by first
setting up the current configuration and then sending an AT command
&Wn. The active profile will be lost if reset commands were issued or the
modem is not powered.

For examples:
ATZ Resets and then configures the modem to

NVRAM user profile 0.

AT&F S0=1 &W1 &Y1 &F configures the modem to factory default

&S0=1 configure the modem to answer after
one ring
&W1 saves the active configuration to profile 1
&Y1 Configure the modem to use NVRAM user
profile 1 as the power-up defaults.

AT COMMAND SET AND S-REGISTER

The modem (DCE) operates in one of two states: command or on-line. In
each state, data and commands (including DCE response) are both transfer
through the UART. In command state, the host (DTE) communicates to the
modem through AT (stands for attention) commands and S-registers. AT
command set is the industry standard used to control the modem in
command state. S-registers are internal modem registers that DTE can
access. AT command set extended by each modem manufacture for the
control of more modem functions and capabilities. For more information,
please refer to the Chapter 5 AT Commands.

INITIALIZATION STRINGS

An Initialization string is a series of specific commands that prepares a
modem to operate with communications software. Consult with your

36

Communication software manual and AT Command to modify INIT
strings.

XMODEM, YMODEM, ZMODEM

These are file transfer protocols used by the host ( i.e. communication
program in the PC). It does error checking and assures data integrity of the
file transfer. There are some other protocols. ZMODEM is the most
preferred protocol to use.

DATA RATE

The modem recognizes AT commands from the DTE, at any valid data rate
from 300 bps to 115,200 bps. However, the DTE should use the data rate
specified for each mode:

Mode Data Rate

(bps)

Data 300-33,600 Modem-to-modem data rates

Affected Data

37

XON/XOFF

A handshaking, flow control mechanism that communicates that the device
is ready to accept more data. The flow control embedded into the data
stream by using special characters with hence transmit on (XON), or
transmit off (XOFF) often referred to as software flow control.

CTS/RTS

CTS stands for Clear To Send. RTS stands for Request To Send, a
handshake line in which the computer tells the modem it can accept new
data.

DCD

Data Carrier Detect

DSR

Data Set Ready. Supplied by the modem to indicate it has power and is
ready to accept commands.

DTR

Data Terminal Ready. Signal generated by the computer to indicate it can
accept data from the modem.

DUPLEX

A communication system that is capable of communicating in both
directions can be half duplex or full duplex. Half duplex allows
communication in both directions, but only one direction at a time, while
full duplex allows data to transmitted in two directions simultaneously.

OFF-HOOK

Pick-up a telephone receiver. You take the modem off hook to dial or
answer and it remains off hook while you are connected.

ON-HOOK

Hangs up a telephone receiver. You are not connected to Telephone Central
Office when the modem is on hook.

38

DTMF

Dual-Tone-Multi-Frequency. The use of two simultaneous audio band tones
for dialing.

CCITT

Acronym for the International Telegraph and Telephone Consultative
Committee. An international organization that decides upon recommended
communication protocol standards. Also see ITU-T.

ITU-T

International Telecommunication Union-Telecom. Formerly CCITT.

Technical tips

1. Make sure the modem card is fully insert into the expansion slot.

2. Check to make sure that the phone and line cables connected to the
correct jacks on the back of the modem.

Some communications software packages allow you to set the initialization
(INIT), dialing, hang-up, and auto answer command strings. In doing so,
you may encounter problems with the following commands:

E0 The use of this command results in an apparent loss of command

echo from the modem.
Solution: Change the command to E1(Default).

M0 This command disables the monitor speaker, not allowing you to

monitor either the dialing or call progress.
Solution: Change the command to M1(Default).

Q1 When this command set, the modem will not return any result code.

Change the command to Q0(Default).

Sn=x This command is use to directly set an S-register value. Some

registrars were well define (i.e. S0.) Other registrars are bit-mapped
and their operation will vary depending on the modem type and
configuration. Typically, S-registers store parameters set by other AT

39

commands.

V0 This command causes the result codes to issued in numeric

code(which may require for some software packages.) However, if
you want the result codes to appear in English text, you will have to
change the command to V1.

Xn This command determines Result Code Type. For some values of n,

the modem will dial without dial tone or BUSY signal detection. The
modem may not report the connect data rate.
Solution: Change the command to X4.

Problems and solutions:

Problem: Modem would not dial

Solution: Check your phone line and cable connections. Make sure that

the line from the wall connected to the LINE jack of the
modem.

Problem: No dial tone message

Solution: Make sure no other phone extension has picked up on the

same line.

Make sure that the telephone line, coming from the wall

connected to the LINE jack and NOT to the PHONE jack on
your modem.

Check to make sure you are using a standard analog

telephone line and not a digital line.

Problem: Modem does not dial correctly

Solution A: Your phone system may require that you obtain an outside

line before dialing. In this case, place the numeric prefix for
the outside line (usually the number 9) before the phone
number in your dialing string.
9 555 3333 To get out of the office

NOTE: Place a comma immediately after the number 9 in the
dialing string to create a 2 second delay at that point in the
dialing. This prevents the modem from dialing the phone
number before the phone system has had time to connect to

40

an outside line.
9, 555 3333 To get a pause

Solution B: You may be trying to dial into another area code; you must

first

dial a 1 before the phone number in your dialing string.

1 555 555 3333 To get into another area code

The other end could be busy or not answering.
Make sure the number you dialed is correct.
Test the number by dialing it on your telephone - not through
your modem.
If you are using the modem internationally, your modem may
not recognize the dial tone in the local country. Try the
command ATX3DT and the telephone number.

41

Problem: Error message

Solution: Make sure you selected the correct modem in your

communications software.
If you are typing from the command line in terminal mode,
make sure you typed correctly.
Make sure you are issuing the correct AT command.
Note: Not all modems support the same AT Command set.
Check the AT Command set in this manual to assure that you

are using a valid AT Command.

Problem: Modem communication error or modem not found

Solution: Make sure you have selected the correct COM Port in your

communications software setup.
Check all the cable connections and make sure they are
secure.
In fax software, make sure you have selected the correct fax
class.
The Port setting in the Control Panel in Windows may not set
properly.

Problem: Modem would not connect.

Solution: If you have no trouble communicating with any modem except

on one particular line, the problem may be with the modem on
the other end of that line.

Problem: Modem would not fax

Solution: Make sure you have selected Class 1 fax class.

Make sure that you do not have another communication
program open.
Be sure you selected the Fax printer in your word processing
program.

Problem: Fax not found

Solution: Re-install or re-setup Fax software with the modem installed.

The Port setting in the Control Panel in Windows may not set
properly; You may have connected the phone line, coming

42

from the wall, to the Phone jack on the back of the modem.
The phone line, coming from the wall, must connect to the
Line jack.

Problem: Modem does not respond to AT Commands

Solution: Make sure the COM port settings in the software match the
hardware configuration.

Make sure the board seated properly (pushed all the way into

the slot).

CHAPTER 5 AT COMMANDS
Overview

The modem (DCE) operates in two states: command or online. In each
mode, both data and commands (including DCE responses) are transferred
through the UART THR (Transmit Hold register) and the RBR (Receiver
Buffer register).

The modem defaults to the command state. In this command state, the host
(DTE) communicates to the modem through AT commands and S-registers.
S-registers contain modem status and configuration information that DTE
can access. AT commands are character strings that guide modem
operation. Many of AT commands indirectly affect the contents of S­registers.

• An AT command string begins with an AT prefix and ends with a
carriage return character defined in S-Register 3 (default: <↵ Enter>).
The A/ (repeat last command) and +++ Escape sequences are the only
exceptions.

• AT command strings can contain multiple commands in the same
string. These commands are placed after the AT prefix and before the
<↵ Enter>. Spaces may be used to separate commands within the string.

• Each command line may include up to 80 characters and spaces.

• The AT prefix and commands may be in either upper or lower case, but

all characters for the given command must use the same case.

• For commands that contain numeric options you may omit the numeric
value and the modem will assume that the number 0 was entered.

• While the modem is attempting to connect to a remote modem, any
character entered is considered an ABORT command. The modem will
go on-hook and enter the command mode.

V.42/V.42bis MNP AT Commands
Data Error Correction and Compression

Your modem supports two types of error correction (MNP2-4 and V.42)
and data compression (MNP5 and V.42 bis). V.42 error correction uses
LAPM as the primary error-control protocol and uses MNP2-4 as an
alternate. V.42 bis data compression requires V.42 (LAPM only). MNP5
requires MNP2-4. The supported V.42 bis/MNP AT commands are listed

REDUCING WARRANTY CLAIM
REJECTIONS.

To reduce the potential of incurring damages not covered by Manufacturers
warranties, we strongly recommend the following:

• read your manuals before installing peripherals and/or before

making changes to the machine’s configuration;

• ask your dealer if there are any known problems with the

system requirements or installation procedures for any add-on
products that your are purchasing;

• buy industry standard products where compatibility issue are

more likely to surface;

• If you are unsure about installation for a new product, contact

your dealer’s service department.

We believe it is important for you to know and understand what your
warranty coverage provides and what it does not.

We also want you to be aware that most hardware warranties only cover the
functions of the hardware. In most cases, no assurances are given by the
manufacturer that the hardware item will work in conjunction with any
other hardware item. If a computer product is not working because it is not

67

compatible with another product, or because it has not been properly
installed and set-up, the manufacturer does not pay for the service time. To
help avoid these inconveniences, contact a professional consultant that can
help you determine the possibility of incompatibility issue before you
purchase add-on products or accessories.
