Status Release
!
By default for incoming calls, TELSAT GPRS is configured for connection of a
telephone to the Phone port, fax machine to the Fax/Modem/Phone port and a
PC for data and SMS to the PC port.
!
The total number of telephones and telecomm equipment connected to the
TELSAT GPRS may not exceed a REN (=Ringer Equivalent Number) of 5. A
standard analogue telephone has the REN of 1.
!
All devices connected to one port of the TELSAT GPRS are switched in parallel.
That means they react in the same way: For example when there are 2 telephone
sets connected to the Phone port and a call comes in, both telephone sets will ring
and you can answer the call using any of them.
!
If you connect a Personal Computer, you have to install the modem driver of the
TELSAT GPRS on the computer.
!
For security reasons, the telephone cables must remain exclusively inside the
house, not go outside the house. The maximum distance between the TELSAT
GPRS and conventional telephone sets or fax machines is 300 meters with 0,4
mm cable assuming a total loop impedance including telephone equal to 500 Ω
maximum. The maximum distance between the TELSAT GPRS and PC should not
exceed 3 meters.
!
If the power supply adapter is disconnected, the TELSAT GPRS is shut down.
Even if the TELSAT GPRS is powered by the internal battery (in case of a mains
failure), the power supply adapter shall be connected to the TELSAT GPRS.

3.4 Enter the PIN number
Before you can use the TELSAT GPRS, enter the PIN (Personal Identification Number).
You will receive the PIN number with the SIM card from your network provider.
!If you have received a TELSAT GPRS with Autopin function read chapter 3.5
before going on.
To enter the PIN use a telephone set connected to the Phone port or the
Fax/Modem/Phone port of the TELSAT GPRS. Use the telephone to enter the PIN (by
sending DTMF codes to the TELSAT GPRS) just as you would dial a number:
When you pick up the handset (go off hook), you will hear a recurrent short beep tone,
that prompts for the PIN. Enter the PIN as shown below, then hang up (place the
handset on hook).
To enter the PIN:
*8 PPPP
It means:
PPPP
Please enter your PIN number here .
Allowed PIN numbers are 0000 to 99999.
means: listen to the confirmation tone:
a high pitched beep signals: OK
a low frequency beep-beep signals: Wrong PIN
You may have to wait 3 seconds before hearing the confirmation tone.
means lift up the handset
means hook on the handset
If you have entered the wrong PIN, the LED will flash rapidly. In this case, try
it once more. If you have entered two times the wrong PIN, you have only one more try
to enter the PIN before the SIM card is locked (see chapter 3.6). This last try is
indicated by a special beep tone.

3.5 Autopin option
Autopin is a special function to prevent against the use of the TELSAT GPRS' SIM card
in another terminal.
Please insert the SIM card as described on page 9 and switch on the TELSAT GPRS.
Enter the PIN of the SIM card. The TELSAT GPRS will automatically change the PIN
number by a secret value. Be careful, you can enter only once a wrong PIN (instead of
twice as in section 3.4).
If the TELSAT GPRS restarts again with this same SIM card, you will no more have to
enter the PIN: the TELSAT GPRS will use its secret value.
TELSAT GPRS with Autopin function can also work with SIM cards with PIN function
deactivated: in this case you will not have to enter the PIN and the TELSAT GPRS will
not change the PIN of the SIM card.
3.6 Enter the PUK number
If you have entered a wrong PIN three times in sequence, the LED will flash
with a significant cadence. In this case you have to enter the PUK (Personal
Unblocking Key) which you should have received from your network provider with your
SIM card. This will unblock the SIM card.
To enter the PIN:
*9 PUK * nPIN * nPIN #
It means:
PUK Please enter your PUK here.
npin
Please enter a new PIN here. Allowed PIN numbers are 0000 to 99999.
3.7 Wall-mounting
The TELSAT GPRS is intended to be mounted on the wall. You can fix it to the wall
with screws.
To mount the device on the wall, first disconnect all the cables. In particular make sure
that the power cable is not connected.
We suggest that you check the reception before finally fixing the mounting.

4 Operation: Making and answering telephone calls
!
Though you can connect many of devices to the TELSAT GPRS only one call -
incoming or outgoing - is possible at a time, because there is only a single
"wireless" line for communication. Other devices will get a busy tone.
!
If a PC data connection (fax, modem or GPRS) is active, you cannot have another
connection in parallel. Incoming calls will not be indicated, although the calling
party may get a ring back tone.
!
You can connect analogue telephone sets either to the Phone port or the
Fax/Modem/Phone port of the TELSAT GPRS. Up to five devices can be
connected to each port but the total number of devices connected to the TELSAT
GPRS shall not exceed five. You can make telephone calls with each telephone set.
Please note that by default incoming voice calls are indicated on the Phone port
only. In order to change this setting please see To select ports for incoming
telephone calls on page 24.
!Please note that the maximum REN (=Ringer Equivalent Number) at the TELSAT
GPRS may not exceed 5. A standard analogue telephone has the REN of 1. All
devices connected to one port of the TELSAT GPRS are switched in parallel and
react in the same way. That means they react in the same way: For example when
there are 2 telephone sets connected to the Phone port and a call comes in, both
telephone sets will ring and you can answer the call using any of them.
!
DTMF dialling as well as pulse (decadic) dialling are supported.
!
Depending on the network, when a number is dialled to make a call, you may need
to enter the local area code, even if it is a local call.

4.1 Call a remote party
To make a call...
, dial....
.... speak...
Lift up the telephone handset and enter the phone number of the
remote party.
You will hear:
!
the common call progress tones, like the dialling tone (before
entering the phone number),
!
the ringing tone (during the time the remote party gets the
RING signal),
!
or a busy signal (if the remote party is busy or the connection
cannot be established).
!If an active connection (GPRS, GSM data, Fax or another
voice connection) has already been established using the
TELSAT GPRS and you try to make a call, you will hear a
busy signal since another device is currently using the only
"wireless" line.
To terminate the
call...
Hang-up the handset.
4.2 Emergency call
You may place an Emergency calls e.g. to your local police or fire department without
a SIM card inside the TELSAT GPRS. Just dial the number.
4.3 To answer an incoming phone call
When the
telephone is
ringing...
... speak...
By default an incoming phone call is indicated by a RING signal of
the telephones connected to the Phone port of the TELSAT
GPRS.
Lift up the handset of the telephone set and speak.
!By default you cannot have two calls at the same time. So if a
call comes in during an active connection (GPRS, GSM data,
Fax or voice connection), this incoming call will not be
signalled to you. And the calling party will get a busy signal,
because the only "wireless" line is used by an other device.
!In some cases you can continue speaking even when you have
hung up and then lifted up the handset within 1 minute. (See
Parameter hang-up delay in the section Advanced
Configuration in the User Manual.)

5 Operation: Send and receive fax with a facsimile device
!You can send and receive G3 fax with a standard analogue facsimile device which
is connected to the Fax/Modem/Phone port of the TELSAT GPRS.
Please install and operate the facsimile device in accordance to its user manual.
!If you want to send or receive a fax with a Personal Computer, which is connected
to the RS-232 port or USB port, you have to configure the TELSAT GPRS
accordingly.
Please note:
The “wireless telephone line” provided by the TELSAT GPRS has special
characteristics you should know:
• Please configure the connected facsimile device so that an incoming call is
answered after the first, second or the third RING signal - not later. Otherwise you
may have problems to receive a fax.
• In case of a faulty fax transmission to a remote party, it might happen
nevertheless that your facsimile will report that the transmission was
successful. So in the case of faulty fax transmission the TELSAT GPRS
will send an error message report to your facsimile device to correct this
problem. Only if you are not receiving such an error message report, you
can be sure, that the fax was transmitted successfully. You can also
activate a mode, that you will receive a transmission report (transmission
successful / not successful) after each fax transmission to a remote
party.
!
• While receiving a fax from a remote party, it might happen that the sending party
already receives the confirmation that the fax has been transmitted to you
successfully even though you did not yet receive it completely for any reason (i.e.
out of paper). In such a case the undelivered part of the fax will be stored inside the
TELSAT GPRS. It will indicate this by both FAX Warning LEDs rapidly flashing (see
The LEDs on the device on page 8). The TELSAT GPRS will do some retries to
deliver the rest of the received facsimile. If it is not successful, it continues to
indicate this by both FAX Warning LEDs rapidly flashing.
You can request the delivery of the partly stored fax by entering a DTMF command
by a connected telephone set (see below In case of a FAX Warning, page 19).
5.1 To receive a Test Fax
To check if your facsimile device can receive a fax from the TELSAT GPRS correctly,
you can make a test:
#*111# A test fax of 1 page will be transmitted from the
TELSAT GPRS to your facsimile device.
means: wait for the confirmation tone (up to 3 sec):
a high pitched beep signals: OK
a low frequency beep-beep signals: Wrong entry.

5.2 In case of a FAX Warning
If both FAX Warning LEDs are rapidly flashing, the TELSAT GPRS is indicating that it
could not transfer a received fax to the connected facsimile device completely (see
above). The part that is not transferred is stored in the TELSAT GPRS. Please check
your facsimile device. Be sure that it is in correct operation mode. Then give the
command to the TELSAT GPRS to transfer the stored fax to your facsimile device. Use
a telephone connected to the Phone port or to the Fax/Modem/Phone port to give the
following command:
Description:
#*222# After you have entered the code, the TELSAT
GPRS will start to send the saved fax part to
your facsimile device.
#*999# This command will delete the partly saved fax
and will reset the FAX Warning.
means: wait for the confirmation tone (up to 3 sec):
a high pitched beep signals: OK
a low frequency beep-beep signals: Wrong entry.
!You can configure the fax function according your needs. See page 31.

6 Operation: Analogue Modem connections
!
With an analogue modem connected to the Fax/Modem/Phone port of the
TELSAT GPRS you can send and receive data to/from a remote modem being
connected to an analogue telephone line or to/from a GSM modem. Please install
and operate the modem in accordance to its user manual and the manual of the
software you run on the computer connected to the modem.
!
Please note that by default incoming data calls are indicated on the PC port. To
change this setting, please see Select Port for Data Calls on page 32.
!
For data communication with your PC directly connected to the TELSAT GPRS,
please see details page 40.
!If the called party’s modem is connected to the fixed network, it must support
9600 bps (V.32) / V.42 for the connection into the fixed network. This is necessary
for the communication to the GSM network.
!The TELSAT GPRS supports
• modem connections up to 9600 bps
• modem connections according to the ITU-Standards V.21, V.22, V.22bis and
V.32.
Your modem should support MNP2 to ensure that no data are lost due to flow
control problems.
!You can configure the function according your needs. See Data Call Configuration,
page 32.
