2. LIMITATIONS OF USE
As the mobile phones are designed for the maximum efficiency of speech conveyance,
the data compression feature which is used in them brings about distortions in the
transmitted audio signals, which may make difficult or even impossible sending modem
signals through a simulated telephone line (downloading, monitoring).
3. DESCRIPTION OF THE MODULE
MODULE TERMINALS:
+12V – power supply input (12 V DC ±15%)
GND – ground (0 V)
FLT – alarm output, SIM300CZ telephone failure or insufficient range (OC; 50 mA)
R-1, T-1 – extension telephone line (connection to the alarm control panel or to a telephone
set)
The FLT output is a generalized fault indicator. It gets active if connection with the base
station is not confirmed by the module within 10 minutes. It may be caused by a telephone
trouble, antenna failure (antenna cable damage), or loss of range due to other reasons.
The fault alarm stops maximum 30 seconds after the alarm causes ceased to exist.

User Manual GSM LT-1S

Figure 2. View of the GSM LT-1S module board.
In its active state, the FLT output is shorted to the ground. The FLT output may be connected
to the alarm control panel input, or it can directly control the relay operation (its maximum
current-carrying capacity is 50 mA).
LEDs:
The module indicates its status to the user by means of 4 LED indicators. The mode of
lighting of the STAT and SIG LEDs depends on the module status and provides
the information described below. The lighting cycle of these LEDs is 4 seconds, repeated
after a 1-second pause.
STAT – indicates the module status by a corresponding number of flashes with specified
duration. Shown symbolically below are single cycles of various LED lighting
modes with their meaning described. The shaded fields meaning the LED "on" and
the blank fields – the LED "off":
– (LED off) module power off
– no PIN code
– wrong PIN code
– PUK code required
– no communication with SIM300CZ telephone
– active connection
– normal operation of module
– module restart on switching power on
– PH-SIM PIN code required
– no SIM card
– SIM card damaged
– SIM card busy

The SIM300CZ cellular telephone is fitted with a special cable, terminated with connector for
external antenna (see: Fig. 2).
4. OPERATING THE SIM300CZ TELEPHONE
As any other cellular telephone, the SIM300CZ industrial telephone requires a SIM
activation card to operate. The user of the GSM LT-1S module and the SIM300CZ
telephone has to obtain such a card on his own. The SIM card should be inserted into
a special recess provided on the right-hand side of the printed circuit board. The PIN code,
if necessary, is to be entered into the module memory by means of a telephone connected to
terminals R-1 and T-1, or by means of a computer and the DLOAD10 program.
NOTE! The change of PIN code stored in the SIM card, or entering the PUK code is possible
after putting the SIM card into an ordinary cellular telephone.
5. INSTALLATION
It should be borne in mind during installation that the GSM LT-1S module must not be located
in the vicinity of electrical installations, since this may involve a risk of malfunctioning. Pay
special attention to how the cable is laid between the module and the telephone terminals of
the alarm control panel.
Never turn on power supply of the module and SIM300CZ telephone without
external antenna connected.
The installation must be carried out in a strict compliance with the following activation
procedure:
1. Make a complete wiring.
2. Turn on the module power supply without SIM card inserted.
3. Using a DTMF telephone set or the DLOAD10 computer program, specify the module
working parameters (including the PIN code).
4. Turn off power supply.
5. Insert SIM card into the socket (see: Fig. 3).
6. Turn on power supply.
A non-configured GSM LT-1S module will wait 10 minutes after power-up for entering the PIN
code of the SIM card. If this does not happen, the device will automatically deenergize the
telephone line and generate the trouble signal (i.e. it will short the FLT output to common
ground), thus making further programming from the telephone impossible (programming from

User Manual GSM LT-1S
6
the computer by means of the DLOAD10 program will still be possible). If this is the case,
turn the module power off and on, so that the module can re-enter the programming mode.
Figure 3. Entering the SIM card into its socket.
The module power supply should have a sufficient current capacity. The recommended
power supply unit (e.g. APS-15; APS-30 manufactured by SATEL) should be equipped with
its own battery.
It is suggested that the power supply be located within 3 m from the module.
If the supply voltage is lower than 9.8 V, restart of the module will follow. Therefore, be
careful that the module supply voltage never drops during operation below 9.8 V at the
maximum current consumption.
6. OPERATION OF THE MODULE WITH ALARM CONTROL PANEL AND STATIONARY
TELEPHONE
As shown in Figure 1, the module is to be directly connected to the control panel’s public
telephone line terminals.
It maintains impedance and voltage across the R-1 and T-1 terminals as necessary for
correct operation of the telephone set. The terminals can be automatically deenergized in
case of a loss of communication with the base station (which is accompanied by operation of
the FLT trouble indicator – see: programming function No. 17).
When the control panel goes „off-hook”, or when a user lifts the handset of a telephone
connected to the terminals T-1 and R-1, the module will generate the continuous dialing tone
and receive the tone or pulse dialing signals (similarly as the telephone exchange).
The telephone number can include digits and special characters: # *+. The phone number
should be dialed just like from a cellular phone, as required by the operator of the network
into which the telephone is logged. It is recommended that the number begin with the „+”
character and country code prefix (48 for Poland). Sometimes you can dial just the mobile
phone number, or the area code and stationary telephone number..
Examples:
[
*][0][4][8][5][0][1][1][2][3][4][5][6] – connection to mobile phone (with prefix „+48”)
[5][0][1][1][2][3][4][5][6] – connection to mobile phone (number without prefix)
[5][8] [1][2][3][4][5][6][7] – connection to stationary telephone, (in this
example, 58 is location area code)

GSM LT-1S SATEL 7
If the first four digits of the dialed number correspond to the pre-programmed „pager station
number”, the module goes to the procedure of receiving the alphanumeric message and
sending it as an SMS text message (see section „Sending SMS messages”). Checking of
the first four digits is always performed.
When connection is established by the cellular telephone, the module will transmit LF audio
signals between the extension line T-1, R-1 terminals and the cellular telephone. After the
handset is lifted by the subscriber the connection is established with, the module changes the
direct voltage polarization across the extension line terminals T-1 and R-1. This function
makes it possible to keep individual tariffication of phone calls.
An option is provided for calling the phone number of the module SIM card. The incoming
calls to the SIM300CZ cellular telephone are directed to the extension line terminals R-1 and
T-1, which generates the ringing tone, in much the same way as with operation of the cable
telephone line. It is then possible to answer the incoming calls by means of a stationary
telephone set connected to that telephone line.
7. GSM LT-1S WITH MONITORING STATION
Figure 4.
The GSM LT-1S module permits site monitoring by means of SMS short text messages. This
function is offered by the STAM-1 monitoring station program, version 4.07 and STAM-2,
manufactured by SATEL. The example of module connection to station is shown in Fig. 4.
Connect the GSM LT-1S module to the computer serial port (COM1 or COM2), by means of
the typical cable for programming the GSM module as well as CA-10, CA-64 or INTEGRA
control panels (see: Fig. 6).
To make the module interface with the monitoring station, you must enter during setup
the communication code, by default 111111. The contents of SMS-messages and the

User Manual GSM LT-1S
8
corresponding codes are to be defined in the STAM-1/STAM-2 program when editing the
client.
8. SENDING SMS MESSAGES
If the control panel has the function of messaging to the pager system, it can be used for
sending SMS messages.
To enable sending the SMS messages, program in the GSM-LT module the telephone
number of Short Message Service Center (function 02 and 10) and telephone number of
pager station (function 06), and in the alarm control panel the telephone number of pager
station, as required, and enter into the control panel memory the appropriate text to be sent.
The telephone number to be programmed in the control panel must consist of:
1. The "pager station number" pre-programmed in the GSM LT-1S module.
2. The cellular phone number to which the SMS message is to be sent (with the country code
prefix, but without the „+” character).
Note: Parts of the number may not be separated from each other by any time interval
(pause); the digits must be sent by the control panel as one sequence in DTMF or
pulse mode. In case the module has any trouble with receiving the „pager” station
number in the tone mode, it is necessary to set the pulse dialing mode in the control
panel.
8.1 PROCEDURE FOR CONVERTING PAGER MESSAGES INTO SMS MESSAGES
When the alarm control panel is "off hook" and after dialing the number – the module checks
the first four digits of that number. If these digits agree with the programmed "Pager tel. No."
in the module, the module receives next digits up to the pause (telephone number to which
SMS message will be sent); then the module sends hand shake signal (similar as pager
station) and receives the message sent by the control panel. Next, this message is
transmitted via the SIM300CZ cellular telephone as SMS text message.
Note: The programmed “Pager station number” must be unique and must not coincide with
the beginning of other telephone numbers.
The SMS sending systems may require adding a prefix with the country code (48 for
Poland). The prefix (without „+”) is to be programmed together with the cellular phone
number.
To enable the transmission of SMS messages, the “SMS center No.”, must be loaded into
the module, depending on the GSM network where the telephone is activated. It must be
preceded by the „+” character and the country code suitable for the operated network.
Parameters of the pager system signal should be programmed at the alarm control panel
(or the DT-1 telephone set) as follows:
control panel 1 C 2 2 0 A 0 E 7 0 8 A
DT-1 C 1 2 2 A 0 E 0 0 7 A 8
8.2 SENDING SMS MESSAGES FROM A STATIONARY TELEPHONE SET
The GSM LT-1S module user has an option to send SMS messages form a stationary
telephone set which generates DTMF signals and is connected to the terminals R-1 and T-1.
This operation is done in much the same way as sending SMS messages in the PAGER
system.

GSM LT-1S SATEL 9
Figure 5. Assignment of
alphanumeric characters to
telephone keypad.
In order to send an SMS you should:
1. Lift the handset of the telephone.
2. Dial in one sequence the "PAGER station
number" and the phone number to which the
SMS is to be sent. The number should be
entered rather quickly, without any time intervals
between consecutive digits (the country prefix
must be entered before the cellular phone
number).
3. The properly received number is acknowledged
in the handset by two beeps generated by the
module. Lack of acknowledgement or a busy
signal means a dialing error and then the
procedure must be started anew (to facilitate it,
you can use the REDIAL option).
4. Enter the text of message following the
instructions below (the time of module waiting for
subsequent characters is not limited):
After calling the function, the module will accept characters in the numeric mode. Pressing
each key of the telephone adds a corresponding digit to the message.
By pressing the [*]key twice you will enter the text mode. In the text mode, each numeric
key (from 1 to 9) has three letters assigned to it (see: figure 5). Pressing a key means
selection of the middle letter. By pressing in turn the key and [*] you will select the left-
hand letter on the given key. The right-hand letter is accessible by pressing the given key
and [#]. In order to reach the space, press the [0] key. To reach the dash, press [0][*], the
point – press [1]. In order to change between the text mode and the numeric mode, press
the keys [0] and [#]. Pressing the [#] key when the module is in the numeric mode results
in ending the programming and sending the message.
The GSM LT-1S can store in its memory 62 alphanumeric characters to be sent as an SMS
message. At an attempt to enter a longer message, the excessive portion of the text will be
omitted. There is no possibility to check the content of entered message. If you hang up the
handset when entering the text, the function will be interrupted without sending any SMS.
9. TEST TRANSMISSION
The test transmission makes use of the calling number presentation function (CLIP) and may
be used to confirm that the GSM LT-1S module is in good working order. This type of
messaging consists in dialing a programmed telephone number by the SIM300CZ telephone
and then breaking the connection after approx. 20 seconds. The message recipient can read
information on the number of the telephone from which the connection was initiated (cellular
phone, ISDN, etc.). If the number is busy, the module will repeat the call. The module will
consider the messaging completed, if it does not receive the busy signal within approx. 10
seconds from dialing the number. The cellular phone user has an option to early „reject”
the connection, but if he carries out this action too early, the module will repeat the call.
Answering the call, either by the user or automatically by the „voice mail”, is recognized by
the module as completion of messaging. The module will use this function to complete the
test transmission by calling in turn each of the preprogrammed numbers. The phone numbers
to be notified should be programmed by means of functions 21 to 24.
The first test transmission is carried out approx. 30 seconds after completion of the module
programming; the second one: after the programmed test transmission period, or randomly
(after a period not exceeding 20 hrs, unless duration of the programmed transmission period

User Manual GSM LT-1S
10
is shorter). Subsequent transmissions are made in accordance with the programmed
parameter. Use function 19 or 25 for programming the duration of intervals between the test
transmissions.
When programming the test transmission data, remember to set the „test transmission
priority” (function 20), as appropriate.
Checking the current module status is also possible (function 99). You should just dial the
SIM300CZ telephone number and hang up after a few call signals. A moment later the
module will answer with a CLIP (one-time, not requiring acknowledgement).
9.1 TEST TRANSMISSION WITH ACKNOWLEDGEMENT
For each of the 4 telephone numbers programmed to be CLIP notified (functions 21–24), you
can select a separate option of sending SMS if there is no acknowledgement of receiving the
CLIP information (functions 36–39). The transmission acknowledgement consists in the
telephone user rejecting or receiving the connection set up by the GSM LT-1S module.
The acknowledgement can only take place within 10 to 20 seconds of the connection set-up.
In addition, the number of attempts (1–15) to make the transmission (functions 32 to 35) can
be programmed individually for each telephone number. Having detected the
acknowledgement of CLIP transmission, the module will finish dialing the given telephone
number. The module will call in turn each of the programmed numbers, starting from the
telephone no. 1. If the module fails to detect such an acknowledgement after making a preset
number of attempts, then it will send an SMS to the given telephone number, provided that
the messaging mode with acknowledgement and SMS send is selected. The message
contents can be standard - „CLIP failed” or programmed. The function 40 makes it possible to
delete the message contents or to enter a default text, while using the computer and
DLOAD10 program you can type in any text.
9.2 TEST TRANSMISSION WITHOUT ACKNOWLEDGEMENT
In the „without acknowledgement” transmission mode, the module will dial the given
telephone number once (provided the number is not busy), irrespective of the programmed
number of test transmission attempts (functions 32–35).
Notes:
•If the cellular phone of the message addressee is OFF or outside the network range, and
the voice mail service is inactive, then an automatic message on the existing situation is
generated in the receiver and no busy signal is sent back. In such a case, the messaging
is considered by the module as completed, while the user loses information on completion
thereof.
•If the voice mail service is active, the user, after getting access to the network, may be
notified, depending on the operator (e.g. by means of an SMS) of the telephone
connection with the module number, without leaving any voice message.
9.3 SMS CONTROL
The telephone numbers to be notified and the test transmission period can be remotely
changed by sending SMS messages to the module. Such messages must contain the proper
password and the programmable parameter (functions 27–31). The module can inform the
user that a change has been made, by sending a return SMS to the telephone number
programmed with function 26. The SMS which is then sent contains information on the
current settings (transmission period and 4 telephone numbers to be notified, also for test
transmission purpose). For the module to return the SMS, the SMS centre number must be
programmed (function 02).

GSM LT-1S SATEL 11
Note: The message sent to the module may contain just the SMS password, but it can also
be longer than the password (the password can be part of a longer word). It is
important that the password be inserted in the initial part of the message text (among
the first 32 characters). This feature makes it possible to load a verbal description of
the performed operation into the memory of the telephone from which the SMS will
be sent. Thus the user does not need to remember the passwords and their
corresponding functions. Only one control password can be sent in one message.
Sending an SMS without any password will cause no reaction of the module.
The received message will be deleted, and the telephone will be ready for reception
of a next text message.
10.MODULE PROGRAMMING
For the module to operate properly, corresponding parameters must be programmed.
The programming is possible by means of a stationary telephone capable of generating
DTMF signals, or by using a PC computer and the DLOAD10 program (version 1.00.17 or
later).
10.1 DLOAD10 PROGRAM
The GSM LT-1S module is delivered together with the DLOAD10 program which enables the
module to be programmed from a computer.
The program is designed for IBM PC/AT compatible computers. It works in any computer
hardware configuration in the WINDOWS (9x/ME/2000/XP) environment. It is recommended
that the program be installed on the computer hard disk.
The GSM LT-1S module communicates with the computer via the RS-232 interface.
To connect the ports, use the cable made as shown on Fig. 6 (the cable symbol acc. to
pricelist: DB9F/RJ-KPL).
For installation of the program run the setup.exe program from a floppy disk delivered with
the module.

10.2 PROGRAMMING BY MEANS OF A TELEPHONE SET (DTMF)
The stationary telephone set makes it possible to program all the module operating
parameters by means of DTMF signals, as well as enables the module status and antenna
signal level to be checked.
In order to change the settings or check the status you should first enter the GSM LT-1S
module programming mode. This operation requires entering a six-digit access code.
By default, this code is [1][2][3][4][5][6] and can be changed. In case you have forgotten the
code after the change, you can only view it or restore it by means of the computer and the
DLOAD10 program.
In the process of programming, the module communicates with the user by means of beeps
that can be heard in the telephone handset. These beeps (tones) are symbolically denoted in
the function description by means of capital letters:
S– short beep
L– long beep
Calling the GSM LT-1S module programming mode:
•Lift the handset of the telephone connected to the module terminals R-1 and T-1
(the telephone must support the DTMF tone system).
•Select the following key sequence on the keypad:
[*][*][*][*][*][*][?][?][?][?][?][?][*][*][*][*][*][*][#]
(6 x asterisk; access code; 6 x asterisk; #)
•The module will confirm entering the programming mode with four short and one long
beeps (SSSSL) hearable in the telephone handset and will wait for individual functions to
be called to program the settings. It will remain in the programming mode until the handset
is hanged up.
Note: The module accepts the call of programming mode irrespective of the signals it
generates in the handset (e.g. the line busy signal can be heard, if there is no SIM
card inserted).
During the process of programming, the module is communicating with the user by means of
beeps hearable in the telephone receiver. These beeps (tones) are symbolically represented
in the function description by uppercase letters:
S– short beep
L – long beep
Programming the module settings
In order to call the programming function, select the function number (two digits), press the
[*][*] asterisk key twice, enter the parameter suitable for the given function and press the [#]
key.
The parameter keys are described by means of the [?] question marks. The number of
question marks is equal to that of the digits of the parameter to be entered in the given
function. Where the number of digits is not precisely defined, then such a parameter is
described with the [?...] symbol (e.g. telephone number).
The numbers of telephones/PAGER stations may contain special characters: #, *, +. In order
to program such a character from the telephone keypad, call the programming function and
press successively the two keys:
[*][1] = #
[*][*] = *
[*][0] = +

GSM LT-1S SATEL 15
Entering a correct command is signaled in the handset by three short beeps (SSS), while
commands which are incomprehensible or have an incorrect number of characters are
signaled by two long beeps (LL).
The function completed, the module returns to the programming mode. If you hang up, the
module will quit the programming mode and return to the normal operating mode.
10.2.1Function list
[0][1][*][*][?][?][?][?][#] – SIM card PIN code (4 digits). The code saved in module memory
does not change the code stored on the SIM card. The [0][1][*][*][#] sequence deletes the
PIN code from module memory.
[0][2][*][*][?...][#] – SMS center number - the telephone number necessary for sending text
messages. The number of its digits must be within the range of 1...16. The entered number
depends on the GSM network, where the telephone is activated. It must be preceded by
the country code suitable for the operated network.
The [0][2][*][*][#] sequence deletes the previously saved SMS center number.
[0][3][*][*][?][?][?][?][?][?][#] – SMS password (6 characters) required for a remote
change of the modem format. Sending to the module of an SMS containing the
[?][?][?][?][?][?]=NN sequence will change the modem operating format available in the
SIM300CZ telephone. The two NN digits define the format as described in the function 08.
Using DTMF signals it is possible to program a password comprised of digits only (0...9),
while using the DLOAD10 program you can program a password comprised of both letters
and digits. The [0][3][*][*][#] sequence deletes the previously programmed password.
[0][4][*][*][?][?][?][?][?][?][#] – SMS password (6 characters) which calls the SERV
modem command. The function applies to interaction between the module and the
CA-64/INTEGRA alarm control panel. Sending to the module of an SMS containing the
programmed password makes the control panel call back to the number saved in its memory
as the "Dload64 telephone"/”DLOADX telephone” in order to start the downloading function.
If the control panel is to call back to another number, the number should be put into the SMC
content as follows: [?][?][?][?][?][?]=dddd. (password, equality sign, telephone number, point).
Using DTMF signals it is possible to program a password comprised of digits only (0...9),
while using the DLOAD10 program you can program a password comprised of both letters
and digits. The [0][4][*][*][#] sequence deletes the previously programmed password.
[0][5][*][*][?][?][?][?][?][?][#] – SMS password (6 characters) which calls the USER
modem command. The function applies to interaction between the module and the
CA-64/INTEGRA alarm control panel. Sending to the module of an SMS containing the
programmed password makes the control panel call back to the number saved in its memory
as the "Guard64 telephone”/”Guard64 telephone” in order to start the remote communication
with the GUARD64/GUARDX program. If the control panel is to call back to another number,
the number should be put into the SMS content as follows: [?][?][?][?][?][?]=gggg. (password,
equality sign, telephone number, point). Using DTMF signals it is possible to program
a password comprised of digits only (0...9), while using the DLOAD10 program you can
program a password comprised of both letters and digits. The [0][5][*][*][#] sequence deletes
the previously programmed password.
[0][6][*][*][?][?][?][?][#] – PAGER station number (4 digits). If the module detects these
digits at the beginning of the dialed number, it will handle the further part of the number as
the number of cellular phone to which it is necessary to send the SMS. The SMS contents
should be transmitted by the alarm control panel in the "pager" system form. The [0][6][*][*][#]
sequence will delete the number.
[0][7][*][*][?][?][?][?][#] – CA-64 station number (4 digits). This function is not used. It
applies to interaction with the CA-64 control panel. The [0][7][*][*][#] sequence will delete the
number.

75 14400 V.110/X.31
[0]9][*][*][?][#] – RS-232 port speed. Parameter defining the rate of data transfer between
the module and the control panel/computer. You should enter a digit to define one of the
following rates:
0 – 4800 bps
1 – 9600 bps
2 – 19200 bps
[1][0][*][*][?][#] – SMS center international number. The option indicates whether the
programmed SMS center number is a full international number.
0 – no (for local networks)
1 – yes (recommended)
[1][1][*][*][?][#] – Fax/Modem. Option indicating whether the user permits a modem
transmission to be carried out by the module. You should program one of the following
values:
0 – transmission disabled
1 – transmission enabled
[1][2][*][*][?][?][?][?][?][?][#] – access code (6 digits) for programming the module by
means of a telephone set. The [1][2][*][*][#] sequence will delete the code i.e. deny the
access to programming. When you delete the code and quit the programming mode, you will
only be able to change the settings and restore the code by using a PC computer and the
DLOAD10 program.
[1][3][*][*][1][2][3][4][#] – restore default settings – the default access code for module
programming is 123456.
[1][4][*][*][#] – check antenna signal strength. The module, by means of handset beeps,
informs the user about the level of received antenna signal. The signaling is same as that of
the SIG LED. The following answer beeps are possible:
two long (LL) – antenna signal strength = 0
one short (S) – antenna signal strength = 1

GSM LT-1S SATEL 17
two short (SS) – antenna signal strength = 2
three short (SSS) – antenna signal strength = 3
four short (SSSS) – antenna signal strength = 4 (maximum)
[1][5][*][*][#] – check telephone status. The module informs the user about its status.
The signaling is same as that of the STAT LED. The following answer beeps are possible:
four short (SSSS) – no SIM PIN code
three short (SSS) – wrong SIM PIN code
short and long (SL) – SIM PUK code required
two short (SS) – no communication with SIM300CZ module
one short (S) – module operation OK
two long (LL) – module restart after power-up
two short and one long (SSL) – PH-SIM PIN code required
eight short (SSSSSSSS) – no SIM card
three long (LLL) – SIM card damaged
four beeps of diminishing length (LlSs) – SIM card busy
long, short, long, short (LSLS) – incorrect SIM card
three short and one long (SSSL) – SIM PIN2 code required
four short and one long (SSSSL) – SIM PUK2 code required
one long, three short and one long (LSSSL) – other error
[1][6][*][*][?][?][?][?][?][?][?][?][#] – enter PUK code (8 digits) into the SIM card. This
function can only be performed when the module status indicates (by LED or beeps) that the
PUK code is required. This code is not stored anywhere, but after entry it is transferred to the
SIM. When the PUK is entered and the telephone is unblocked, the PIN code currently
programmed in the module settings will be loaded into the SIM memory.
NOTE! After entering the PUK code, the SIM card will get unlocked and its PIN code will be
changed to that currently programmed in the module memory. In order to avoid such
a situation, the PIN code entered by user into the module memory must be identical
to that saved on the SIM card. The DLOAD program enables viewing the PIN code
currently programmed in the module, to prevent the card from being blocked.
Entry of a correct PUK code will be confirmed by three short beeps (SSS) – this confirmation
will appear after a few seconds' delay because of the data processing in the SIM300CZ
telephone. If the PIN code is not entered into the module, the function will not be executed
and the device will generate two long beeps (LL).
[1][7][*][*][?][#] – deenergizing the telephone line together with signaling fault at the FLT
output:
0 – do not switch off voltage on telephone line terminals,
1 – switch off voltage on telephone line if FLT is active
(programming mode – if it was turned on before activating FLT, it will be operative, but only
until hang-up).
[1][8][*][*][?][#] – generating the routing signal (sound signal for setting up connection):
0 – routing signal OFF,
1 – routing signal ON.
[1][9][*][*][?][#] – test transmission. The function enters the period of CLIP test
transmission in a simplified way. The following values can be entered:
0 – no test transmission,
1 – test transmission period 2h58min,
2 – test transmission period 5h57min,
3 – test transmission period 11h56min,
4 – test transmission period 23h55min,
5 – test transmission period 2d23h53min,
6 – test transmission period 6d23h30min.

If the function is called by entering [1][9][*][*][?][?][#], the second "?” character will
determine whether the test function is to be random or not:
0 – no,
1 – yes
By default, the random transmission is disabled.
[2][0][*][*][?][#] – test transmission priority. This option determines whether the test
transmission will override the call being just carried out by the module. If yes, the current
connection will be terminated whenever there is a need for the test transmission. If no, the
test transmission will be carried out on completion of the call by the control panel/user:
0 – no,
1 – yes.
[2][1][*][*][?...][#] – telephone number 1 for the test transmission. The number of digits
must be within the range of 1...16. The number should be programmed with „+” at the
beginning, followed by the country code. The [2][1][*][*][#] sequence will erase the previously
saved telephone number.
[2][2][*][*][?...][#] – telephone number 2 for the test transmission. The same settings as
for telephone no. 1.
[2][3][*][*][?...][#] – telephone number 3 for the test transmission. The same settings as
for telephone no. 1.
[2][4][*][*][?...][#] – telephone number 4 for the test transmission. The same settings as
for telephone no. 1.
[2][5][*][*][?][?][?][?][?][?][#] – test transmission period (6 digits: ddhhmm). As distinct
from function 19, this function enables any transmission period to be entered.
The programmed digits have the following meaning:
dd – number of days (max. 31),
hh – number of hours (max. 23),
mm – number of minutes (max. 59).
If the function is called by entering [2][5][*][*][?][?][?][?][?][?][?][#], the seventh "?”
character will determine whether the second test transmission is to be random or not:
0 – no,
1 – yes.
By default, the random transmission is disabled. Programming zeros only will reset the test
transmission.
[2][6][*][*][?...][#] – telephone number to confirm SMS control. The number to which the
module will send an SMS to inform about the current settings, provided that the user has
changed the settings by means of an SMS. The telephone number must be preceded by the
„+” character and country code, corresponding to the currently used GSM network.
The [2][6][*][*][#] sequence will erase the previously saved telephone number.
[2][7][*][*][?][?][?][?][?][?][#] – SMS password (6 characters) makes it possible to remotely
change the test transmission period. Sending to the module an SMS with the
[?][?][?][?][?][?]=P sequence, where P is a parameter corresponding to the description
contained in function 19, will save the new parameter, programmed with function 19, in the
module memory. Using the DTMF signals, you can program passwords composed from digits
only (0...9), whereas the DLOAD10 program makes it possible to program passwords
composed from letters and digits. The [2][7][*][*][#] sequence will erase the previously
programmed password.
[2][8][*][*][?][?][?][?][?][?][#] – SMS password (6 characters) makes it possible to remotely
change the telephone number 1 for test transmission. Sending to the module an SMS
with the [?][?][?][?][?][?]=nnnn. sequence (password, equality sign, telephone number, dot),
where nnnn is the new telephone number 1 for test transmission,will change the parameter
programmed with function 21. The new telephone number must be identical in form to that
