Features
The VECTOR Plus GSM interface is used, toghether with an approved telephone set or dialler,
to send and receive telephone calls through the GSM network, when PSTN line is missing.
The interface continuously monitors the PSTN line; when a fault condition is detected VECTOR
Plus switches the telephone equipment connected to its terminals to an internal telephone line
simulation circuit, able to manage calling procedures eventually started by the telephone
equipment, including dial tone and busy tone generation, dialling sequence recognition and
ringng signal generation. Thus VECTOR Plus can be used in a bidirectional way: to send
and/or receive GSM telephone calls.
Additionally, VECTOR Plus can send technical and alarm SMS messages to a maximum of 50
telephone numbers.
VECTOR Plus has also the possibility to send a periodic SMS message (autotest) within a
programmable time interval.
Operation
In normal installations, VECTOR Plus is connected to PSTN line, to alarm telephone dialler and
to telephone handsets of the premise. When the PSTN line voltage (normally 48V) goes below
about 35V, VECTOR Plus starts monitoring the line looking for the dial tone frequency (425Hz
typical). If that signal is not detected within 30 seconds, the interface switches automaticly to
"GSM mode", bringing the alarm dialler to the internal telephone line simulation circuit, whereas
the telephone sets are bypassed directly to the PSTN line.
In this condition, if the dialler attempts to execute a telephone call, VECTOR Plus generates the
dial tone signal like the normal telephone line, and waits the dialling sequence from the external
device (only DTMF dialling is accepted). After the dialling sequence is completed the call is
routed through the GSM unit and VECTOR Plus generates the ringing tone and/or busy tone.
Once the GSM connection is established the voice channel stays open allowing data and voice
signals transfer between the dialler and the called party. At the end of the call, as the dialler
realeases the simulated PSTN line, the GSM connection is interrupted. When terminal "GSM -"
is open, VECTOR Plus waits 60 seconds, after a call through the GSM channel, before
switching back to "PSTN line mode" (normal mode), provided that PSTN line voltage has
returned to its normal value (aprox. 48V).
When the "GSM" terminal is closed to negative or in case of permanent fault of PSTN line,
VECTOR Plus interface allows receiving calls through the GSM channel, since, when an
incoming call is detected by the GSM unit, a valid RING signal is generated at the simulated line
terminals of VECTOR Plus, causing the ring detector of the dialler or the ringing bell of a
telephone to be activated.

Other display indications
As stated before, at power up an initialization procedure of about 1 minute takes place, during
which the equipment configures itself according to programming parameters stored in the SIM
card. The 7-segments display shows some default characters to indicate the advancement of
this process:
at the beginning, a line shifts on the display from bottom to top. Then an A character flashes
for about 30 - 40 seconds. Finally, a C character shows till the end of the initialization, when the
led bar will start to indicate the signal strength.
Additional messages on the display:
: An horizontal line shifting from bottom to top is displayed when sending an SMS message.
C : The C character is displayed when executing the periodic autotest with SMS sending.
F (flashing) : This character indicates PSTN line fault condition.
8 (blinking) : Indicates an incoming call through the GSM.
Trouble and Fault messages:
0 = VECTOR Plus is not able to turn on the GSM unit.
1 = Wrong or missing serial comunication between VECTOR Plus and GSM unit.
2 = Wrong PIN security code on the SIM card.
(correct value 0000)
3 = No GSM service available
4 = Poor signal level
5 = Battery problem (only when using standard cell phone)
6 = Unknown general problem
Testing VECTOR Plus
In order to verify the efficiency and the signal quality of the GSM channel, we suggest the
following test: connect a normal telephone set to terminals Ac - Bc of the interface and close to
negative the terminal "GSM". Power up the unit and wait the initialization process is completed
(see display). Execute some telephone calls and evaluate the signal and audio quality of the GSM
connection.

SMS functions
The phone numbers to which SMS messages are going to be sent and the SMS messages
text, must be stored into the SIM card. To execute this operation use a normal cell phone.
Before programming the SIM card, please erase completely the existing contents that could be
stored into it. Note that the first three (3) SMS messages stored into the SIM card are used for
technical purposes, and are sent automaticly by VECTOR Plus when the respective monitoring
functions are enabled. This messages are:
SMS nr. 1: PSTN line fault.
SMS nr. 2: PSTN line restore
SMS nr. 3: Autotest
NOTE: if one or more of the above technical messages is NOT required, it is possible to store a different
message in the corresponding SIM card space to be sent "by command" as will be described in the
following chapters.
To enable/disable the functions that send technical SMS messages automaticly, two special
numbers must be stored into the SIM card phonebook, that are used to configure the system.
This two numbers has to be associated to the names "1" and "2"
(instead of "Smith" or "Johnson").
The digits included in the number under name "1" determine wheather the three types of
technical SMS messages are to be sent or not, and wheather the technical messages are to be
sent to all the telephone numbers present in the phonebook
(max. 50) or only to the first one. The
number stored under name "2" indicates the autotest repetition intervall (in hours: from 0 to 255).
All the telephone numbers to which the SMS messages will be sent must be stored into the SIM
card phone book, keeping in mind that the first number stored has a priority over the rest of the
numbers, because it is the one which technical SMS messages are sent to by default, otherwise
differently specified in configuration parameter "1".
Apart from the technical SMS, that are automaticly sent by VECTOR Plus once they has been
enabled through the configuration numbers, the remaining SMS stored into the SIM card by the
installer to communicate any kind of alarm or status information, can be sent through the
VECTOR Plus interface only in "by command" mode, issuing special DTMF sequences at
terminals Ac - Bc like executing a normal telephone call. Note that, for alarm or status SMS
messages to be sent, it is necessary that VECTOR Plus interface is operating in "GSM mode",
therefore, it is suggested to use an output from the telephone dialler or control panel to force
VECTOR Plus into GSM mode through terminal "GSM", before issuing the proper DTMF
sequence to send the SMS. This is not necessary if the equipment is already functionning in
permanent GSM mode, with terminal "GSM" always connected to negative.
Parameters programming (automatic SMS)
SIM card phonebook .Parameter "1": the values stored under this name into the phonebook determine wheather
technical SMS messges must be sent or not.
Including the digit 1 in the number enables sending the "PSTN line fault" SMS messages.
Including the digit 2 in the number enables sending the "PSTN line restore" SMS message.
Including the digit 3 in the number enables sending the "Autotest" SMS message.
Including the digit 8 in the number, technical SMS messages are sent to all telephone numbers
present in the phonebook
(max. 50), otherwise they are sent only to the first telephone number of
the phonebook.
Parameter "2": the value stored under this name into the phonebook represents the repetition
intervall
(in hours), of the autotest SMS message. This value should be between 0 and 255.

Numero: 12
Parameters programming (SMS by command)
It is possible to send SMS messages stored into the SIM card using a standard touchtone
telephone set connected to terminals Ac - Bc. If the PSTN line is present, to send SMS
messages "by command", it is necessary to close to negative by a few seconds the terminal
"GSM" of the unit, to force it into GSM mode. In contrast, if the PSTN line is not available,
VECTOR Plus is supposed to be already operating in GSM mode.
Sending an SMS message "by command" is like dialling a normal telephone number. The
sequence of DTMF digits to be sent is the following: 0000nnTT, where;
0000: is a prefix that informs VECTOR Plus that the sequence is not a normal telephone call but
an SMS message request. (NOTE: although VECTOR Plus were connected through an internal PABX
and were configured with DIP3 in ON position, which causes elimination of the first digit of the number
when calling through GSM, IT IS NOT NECESSARY TO ADD A"0" digit to the prefix to activate SMS
function. The prefix must always be 0000)
nn: is the number corresponding to the SMS message that has to be sent, and depends on the
order messages were stored into the SIM card when programmed. Remember that, as explained
before in this document, the first three SMS messages are used for specific technical
communications and their content shall be wrote according to their function, however, if some of
this technical messages are not required, they can be filled up with a different text to be sent "by
command" when needed.
TT: is the position into the SIM card phonebook of the telephone number to which the SMS
message has to be sent. Like for the text messages, the position of telephone numbers also
depends on the order they were stored into the SIM card when programmed. Issuing "99" as the
value of TT, the selected SMS message will be sent to all telephone numbers (max. 50) contained
in the SIM card phonebook.
Example 1:
Dialling: 00000712
VECTOR Plus will send the SMS message stored in position 7 of the SIM card to the telephone
number stored in position 12 of the internal phonebook.
Example 2:
Dialling: 00000599
VECTOR Plus will send the SMS message stored in position 5 of the SIM card to all telephone
numbers in the phonebook.
NOTE 1: to enable sending an SMS by command when VECTOR Plus is not operating in GSM mode, simply
shortcircuit to negative for a few seconds the "GSM" terminal of the equipment, while dialling the DTMF
sequence for SMS activation. Once the SMS message has been sent, the operation will return to normal
mode and successive telephone calls will go on over PSTN line.
NOTE 2: after issuing the SMS activation sequence, the dialling equipment must wait the initiation of SMS
sending procedure, indicated by a "shifting line" in the display (see Display indications chapter), before
releasing the simulated line at Ac - Bc terminals, otherwise, the SMS procedure is aborted.

Dialler programming to send "by command" SMS messages
To make a telephone dialler connected to VECTOR Plus activate SMS messages "by
command", the following steps are required:
1: program one of the telephone numbers of the dialler with the proper digits sequence
(0000nnTT) as explained hereon.
2: associate to that telephone number some default communication protocol.
3: program the dialler to make one single calling attempt to that telephone number. If there are
repetitions, the SMS message will be sent many times.
4: program an output from the dialler or control panel to activate by a few seconds bringing to
negative "-" the "GSM" input terminal of the interface, while the telephone number is being
dialled.
NOTE 1: using AVS ELECTRONICS diallers or control panels, setting to "0" the number of attempts of
telephone calls will cause the dialler to make one single calling attempt.
NOTE 2: if the telephone number for SMS activation is not the first number "called" by the dialler, once the
"GSM" input terminal of VECTOR Plus has received the pulse to negative, all telephone calls previous to
the SMS activation number will be executed through the GSM channel, while successive ones will occur
over PSTN line.
Example:
Tel. numb 1: alarm telephone call
Tel. numb 2: alarm telephone call
Tel. numb 3: alarm telephone call
Tel. numb 4: SMS activation command
Tel. numb 5: alarm telephone call
Tel. numb 6: alarm telephone call
