Chapter 1 INTRODUCTION

The Data Modem you have purchased represents the latest state of the art in data

communication; its comprehensive facilities provide all you will need for professional

data transfer purposes. Due to the limitation this equipment allows you to receive data

with up to 54kbps from your Internet Service Provider (ISP). The maximum

transmission speed is 33.6kbps. Fax transmission and reception is working up to

14.4kbps.

What is a Modem?

The word “Modem” is derived from the terms “MOD-ulator” and “DE-modulator”.

Putting it more simply, it is a device which modulates digital information into an

analogue carrier signal (tones) and demodulates the carrier signals which it receives,

changing them back into digital data. This permits the transmission of data along

wires, between data terminal equipment (computers, terminals, etc…).

About this Modem

This modem operates as a full duplex, voice-band modem, where signal transmissions

are made in both directions simultaneously and the analogue signals which are

transmitted are in the voice-band of the telephone network.

Data transmission between modem and terminal unit is in serial form - in other words,

the individual data bits are sent, one after another, along a single transmission or

receiving line. At this stage, a word of explanation regarding synchronous and

asynchronous data transmission. In the synchronous mode, additional synchronization

signals are required, to synchronize the transmission and reception signals. In the

asynchronous mode synchronization is by means of “start-bits” and “stop-bits” which

mark the beginning and end of each data word. The modem can dial by itself and also

react automatically to incoming calls. The information it needs in order to dial a

telephone number, together with the various configuration commands, are provided by

the respective data terminal equipment via the same serial interface which is used to

send the data. In this mode, the system operates with the so-called “AT” command set.

INTRODUCTION 1-1

The 56K Technology

The V.90 modem represents the latest V.90 technology. This allows receive data rates

of up to 57.333 kbps over PSTN (public switched telephone network) only in

connection with equipment-compatible ISPs (Internet Service Provider): however, due

to the limited power levels of the PSTN the receive speed is limited to 54 kbps.

1-2 INTRODUCTION

Auto-Answering

With the delivered Software you can use your Modem like an answering machine.

Voicemail can be recorded over the soundcard. To replay recorded voice or messages

you can use a soundcard.

Installation Instructions

1. Use the interface cable supplied to connect the modem to a free COM inter-face

on the computer

2. Use the telephone cable supplied to connect the modem to a Telephone jack

3. This device must only be connected to computers or other device that are in

accordance to EN 60950 regulation and fulfill the respective EMC and safety

standards.

4. When the “POWER” LED is lit, the modem is ready for operation and will

provide data communication, using the factory settings which have been installed

Windows 95/98

Windows 9x will recognize the modem after a reboot of your PC. Put in the CD with

the driver when Windows 9x asks for it and follow the instructions on the screen.

Please read the instructions for the installation of new hardware in your Windows-

Manual.

=> Now you can configure and use the modem with the communications-, fax- and

Voiceprograms.

Installation with Windows NT4.0

Open the option modem with Start – Settings – Control Panel– Modem. The modem

installation window will be opened. In this window press the button: Choose modem

(no automatic recognition) and the button Next. Press the button Diskette. Put in the

CD which has been delivered with the modem and select the CD drive. A list will be

shown with all the modem-drivers. Choose your modem and press the button Next. In

this window choose the com port to which the modem shall be connected, for example

com4, and press the button Next. The configuration of your modem will be started.

Press the button Finish to finish the installation. Please read the instructions for the

installation of new hardware in your Windows-Manual.

Factory settings

To make it easier for you to use your modem, two basic settings have been made at the

factory, which are suitable for most of the connections. These settings can be activated

with the “&F” command. In the fax mode or voice mode, the relevant software will

carry out control of modem settings for you.

 For Data Transmissions select AT&F0. In this condition, the modem will

attempt to create an error-corrected connection with data compression, depending

on the capability of the remote side.

Chapter 2 AT COMMANDS:

DATA MODEM

Guidelines for Using AT Commands

The modem is programmed with AT commands from the data terminal equipment

(computer, PC or terminal) and thus also receives instructions to cover automatic

dialing. The communications or fax software will carry out most of these operations

for you, so that in general circumstances you do not need to have a detailed

understanding of the commands which are described below.

The modem must be in Command mode before it can accept commands. In this

condition, all the characters sent from the computer are interpreted as commands and,

where appropriate, confirmed by a modem message on the screen. When a connection

is set up to a remote modem, the modem will switch to data mode and transfer all the

characters it receives to the other party.

The modem can be switched from an existing connection, back into the command

mode, by using the Esc Sequence (+++), without breaking off the connection to the

remote modem. In this status, any commands which are entered will not be transferred

to the remote modem.

The modem is activated by AT commands, the subsequent value of which will modify

the form of the command. Modem messages provide information on the form of the

commands.

In the Hayes Command Set, commands are entered by the character sequence AT (at)

and can also be entered as a list of commands with or without spaces between the

individual commands. The “Backspace” key is used for deleting. Commands can be

entered in upper-case or lower-case, but all characters for a given command must use

the same case. In the command mode, the modem automatically recognizes data

frames and data speed.

=> AT commands can be transferred to the modem at the following data speeds:

115 200, 57600, 38400, 19200, 9600, 4800, 2400, and 1200 bps

Examples of Command Syntax:

ATX3<CR>

ATQ0<CR>

ATDT12345<CR>

Individual commands ending with the <CR> Enter key, can be entered in a different

manner with the same effect, by inserting as many spaces as you need, to make the

command easier to visualize

ATX3QODT12345<CR> or:

AT X3 Q0 DT 12345<CR>
