Fax mode In addition to the modem modes, the ELSA MicroLink®modems described
here are equipped with both the SendFax and the ReceiveFax function (see
also section 5.9, page 82). Using the supplied fax software, it is possible to
conveniently send and receive text and image documents at rates between
14,400 and 2400 bps. The support of fax command sets Class 1 and Class 2
make it possible to use any standard fax software (e.g. Delrina WINFAX) and
also the E-mail functions within Windows 95 and Windows for Workgroups.
Polling operation ELSA MicroLink modems support the fax polling mode which, together with
suitable fax software, allows the polling of fax documents and the operation
of a polling system.
Bit rate adaptation The ITU-T V.100 and ITU-T V.8 procedures are used for determining the bit
rate used by the remote modem. This means that MicroLink modems adapt to
the highest possible bit rate common to both devices. The bit rate adaptation
can be disabled.
MNP4 and V.42 The error correction protocols implemented in the MicroLink modems (MNP4
and V.42) allow 100% error-corrected data transmission even with poor
quality telephone connections. ELSA MicroLink®modems with MNP4 or V.42
can establish reliable, error-corrected connections with other similarly
equipped modems.
MNP5 and V.42bis MicroLink 33.6TQV, MicroLink 28.8TQV and MicroLink 14.4TQ also use the
data compression methods MNP5 and V.42bis. Using MNP5, the transfer
rates can be doubled, or even quadrupled in the case of V.42bis. Therefore
MicroLink 33.6TQV, MicroLink 28.8TQV and MicroLink 14.4TQ can achieve
effective transfer rates up to 115,200 bps or 57,600 bps, respectively!
AT command set The "AT command set" is used for communication with MicroLink modems.
This language has become the de-facto standard for dial modems.
Voice function MicroLink 33.6TQV and MicroLink 28.8TQV are equipped with a voice function,
allowing you to use your modem as an answering machine in connection with
the supplied voice software (see section 5.10, page 84).
Password protection The password protection serves to protect your modem from being used or
configured by unauthorized persons. By means of a password (the so-called
supervisor password) certain modem functions can be locked. Up to five
access flags can be used to define which functions are locked.
Automatic callback This feature can used to make your modem call back automatically when it is
called by another modem. Up to 19 callback numbers with corresponding
passwords can be stored using the AT$P command.
Remote configuration The remote configuration allows you to configure your modem from any
location you can call from. This feature can be used directly or in combination
with the automatic callback function. Up to 19 different user passwords can
be stored using the AT$P command.

country.
3.1 BABT Approval (United Kingdom)
This section applies only to the BABT approved British versions of the ELSA MicroLink ®modem.
This apparatus has been approved by the BABT for the use of the following facilities:
n Modem facility
n Fax facility
n Auto calling
n Auto Answer
n Hands-free telephone facility
àATTENTIONàAny other usage will invalidate the approval of the apparatus if as a
result it then ceases to comply with the standards against which
approval was gained.
In addition, as the owner and/or operator of this apparatus you should regard the following points:
n If you want to connect your modem to the British Telecom PSTN, you are required to fill in the
form found on the last page of this manual and send it to your local BT agency in order to have
the appropriate connection socket installed. Please don't forget to enter the approval Number of
your modem. You will find the Approval Number printed on the label placed on the modem
housing.
n The modem can only be connected to direct exchange lines. It cannot be operated in shared
service or 1 + 1 carrier systems. Further, the modem cannot be used as an extension to a
payphone.
n This modem has a Ringer Equivalence Number (REN) of 1, which is the same as the REN of a
standard BT telephone. The REN is used to determine how many devices can be connected to

National Regulations
12 MicroLink 33.6TQV / MicroLink 28.8TQV / MicroLink 14.4TQ Manual © 1997 ELSA GmbH
your telephone line. The sum of the RENs of all devices on any line must not exceed four (4.0).
Attaching too many devices may mean that they do not ring properly. The REN of your modem
can also be found on the label placed on the modem housing.
n Before operating the modem, make sure that it is properly connected to the power supply and
switched on. Refer to chapter 4"Setting up the Modem" for installation instructions.
n The telephone line the modem is connected to must provide loop disconnect signaling (pulse
dialing) or DTMF signaling (tone dialing). The modem supports both dialing methods. Selecting
the appropriate method is described in section 5.5 of this manual, "Description of AT
Commands".
àNOTEàAlthough this equipment can use either loop disconnect signaling (pulse dialing) or
DTMF signaling (tone dialing), only the performance of the DTMF signaling is subject
to regulatory requirements for correct operation. It is therefore strongly
recommended that the equipment is set to use DTMF signaling for access to public
or private emergency services. DTMF signaling also provides a faster dialing
process.
n Within private branch exchange (PABX), dialling an external number may require the user to
insert a PSTN access digit, e.g. a digit 9 (external access code). See section 5.5 of this manual
for details about connection establishment.
n This modem is capable of storing several phone numbers which can be dialed automatically.
Check that all stored numbers are correctly programmed before using the auto-dialing function.
àNOTEàThe V.24/RS-232C interface on the rear side of the modem housing is a connector to
a SELV circuit (Safety Extra-Low Voltage), complying with EN 41003 Clause 4.1.3.
Any part of this connector can be touched without the risk of electric shock.

National Regulations

3.2 HDTP Approval (the Netherlands)
This section applies only to the Netherlands versions of the ELSA MicroLink ®modem approved by the
Hoofddirectie Telecommunicatie en Post (HDTP). This modem model may not yet be HDTP approved at
this time.
n The Connection Factor (aansluitfactor), which can be found on the HDTP approval label on the
housing of your modem, provides a guide as to the maximum number of pieces of equipment
(both in the idle state and for call detection) that can be connected in parallel to a single
telephone line. The sum of the connection factors for all the devices connected to the telephone
line must be less than five (5.0).
n Some telephone exchanges in the Netherlands still provide a dial tone in the frequency range
between 100 and 200 Hz which will not be recognized by MicroLink. It is therefore possible that
the modem will not function properly at all public telephone exchanges. Dial tones in the
frequency range between 340 and 550 Hz are properly recognized. Information concerning the
different types of exchanges can be obtained from the PTT-Netwerkbedrijf.
3.2.1 Voor Uw Veiligheid
Met betrekking tot uw veiligheid, het goede functioneren van uw nieuwe ELSA MicroLink ®modem en
uw computer, dient u de volgende regels in acht te nemen.
nOm kontakt met gevaarlijke spanning van de telefoonlijn en/of schade aan het modem te ver-
mijden, dient het telefoonsnoer en de voedingskabel van het modem te worden verwijderd voor-
dat u de behuizing van het modem opent. Normaliter dient de modem behuizing overigens niet
geopend te worden.
nEen telefoon verbinding maakt gebruik van gelijk- en wisselstromen om bel-signalen te kunnen
genereren. Het telefoonlijn circuit (TNV) kan onder gevaarlijke spanning staan. Elk lichamelijk
kontakt dient hiermee te worden vermeden.
nOm veiligheidsredenen dient uitsluitend de originele externe voeding, welke bij uw modem
wordt geleverd, te worden gebruikt. Een geopende voeding of een mechanisch beschadigde
voeding mag niet langer gebruikt worden want als de primaire wisselspanning (230 volt) met de
hand of metalen delen wordt aangeraakt kan dit leiden tot een electrische schok welke dodelijk
kan zijn.
nDe V.24/RS-232C verbinding op de achterzijde van uw ELSA MicroLink®modem, is de verbinding
met een z.g. VELV circuit (Veligheids Extra Lage Spanning) welke overeenkomt met de norm EN
41003, clausule 4.1.3. Elk gedeelte van deze connector kan worden aangeraakt zonder risico van
een electrische schok.
nRaak de pennen van de modem connector niet aan, want de kleinste hoeveelheid vuil of
electrostatische ontlading, kan leiden tot slecht functioneren of zelfs defect raken van uw
modem.

4 Setting up the Modem
4.1 For Your Safety
In the interests of your safety and the correct operation of your new ELSA MicroLink®modem with
your computer system, please observe the guidelines listed below.
àIMPORTANTàSee chapter 3 ("National Regulations") for specific safety
instructions!
n In order to avoid contact with hazardous voltage of the telephone line circuit or damage of the
modem, be sure that you have unplugged both the power supply and the telephone line from the
modem before opening the housing! It is not normally necessary to open your modem at all.
n A telephone line uses direct current and alternating current for ring signals. The telephone line
circuit (TNV) can have hazardous voltage and must not be touched.
n For reasons of safety, use only the original external power supply shipped with your modem.
A power supply that has been opened or mechanically damaged should no longer be operated;
touching the primary voltage (Europe: 230 V, USA: 120 V) with the hand or with metal parts
results in an electric shock which can be deadly.
n The 9 VAC power input of the modem is a low voltage circuit; touching this circuit with the hand
or with metal parts does not normally cause an electric shock.
The V.24/RS-232C interface on the rear side of the modem housing is a connector to a SELV
circuit (Safety Extra-Low Voltage), complying with EN 41003 Clause 4.1.3. Any part of this
connector can be touched without the risk of electric shock.
n Please do not touch the metal pins of the modem connectors. Even slight dirt or electrostatic
discharge may cause malfunctions or, in extreme cases, damage to the modem.

4.3 Hardware Installation
The installation of your modem is performed as follows:
1. Power connection Make sure that the voltage of the power line matches the voltage of the
supplied AC adapter. Then connect the modem to the power line using the
AC adapter.
àATTENTIONàFor your safety, use only the original power supply shipped with your modem!
2. Connecting to Select the appropriate serial asynchronous communication interface (COM
the computer port) by referring to the operating instructions of your computer or terminal
and connect the modem to this interface using the supplied RS-232C cable
and adapter if required.
It is highly recommended that the selected serial port should be equipped with
a UART chip (Universal Asynchronous Receiver/Transmitter) with a FIFO buffer
(type 16550). Without such a UART, error-free transmission across the serial
interface at rates over 9600 bps cannot be guaranteed.
The supplied diagnostic program MODEMTST.EXE can be used to check which
UART type is used on the selected interface. If it is not a 16550 UART, we
recommend you to upgrade or replace your serial interface board.
àELSATIPàFor example, ELSA offers the COMFAST ®serial interface board, featuring
two freely configurable serial ports, each equipped with a 16550 UART.
When selecting the serial interface, be aware of the corresponding IRQ
settings, especially for COM3 and COM4. Make sure that each IRQ is only
used by one device, otherwise hardware conflicts and PC malfunctions may
occur. For example, it is common for COM3 to share IRQ4 with COM1, and
COM4 to share IRQ3 with COM2, which could lead to a conflict.
Changing an interrupt is normally performed by changing a DIP switch or a
jumper on the serial interface board. Please refer to the manual for your serial
interface board for instructions.
à
NOTE
à
If your computer only has a 9-pin connection socket, you will need an
appropriate adapter, which has all nine lines connected. If some of the lines
are not connected, malfunctions (e.g. transmission errors) may occur.
3. Connection Connect your modem to the telephone network by connecting one end of
to telephone the supplied connection cable (RJ11 plug) to the line connector on the rear
network panel of the modem (see illustration on page 18) and the other end to the
appropriate connection socket installed by the respective national telecom-
munications service.
4. Switching the Switch the modem on using the switch on the rear panel of the modem.
