SIM card
Your network operator provides you with a SIM
(Subscriber Identity Module) card. The SIM card
contains information about your telephone number
and the services included in your subscription, among
other things.
Warning!: the FCT has to be switched off before
inserting or removing your SIM card.
Reset
Connections
Warning!: please, before you start any connections
refer to section “Safe and efficient use” on page 51
in this guide and contact your network operator if
you have any questions.
Warning!: to get a good FCT protection against
electrical discharges and the best audio quality,
a good grounding of the power supply is strongly
recommended.
Installing the FCT as a telephone line
The FCT is designed to provide a telephone line
(RJ11 connector) to which up to 3 Fixed Line devices
can be connected in parallel. The FCT provides a
single telephone line, which means that only one
communication can take place simultaneously, in the
same way as the ordinary fixed line (you cannot, for
example, receive or originate a telephone call while
sending or receiving a fax).
Warning!: in order to avoid GSM interferences
(noise), place the FCT at least 3 meters (horizontal)
away from electronic devices, including the
telephone equipment connected to the FCT, or other
household electronic devices such as televisions or
radio receivers. The difference in height should be
at least 2 meters (vertical). This is not necessary if
you use telephone devices that fulfil the Immunity
Characteristics settled by the IEC CISPR-24
standard. In this case, a minimum security distance
of 20 cm is recommended.
The FCT is also equipped with an RS232 port that
enables you to use it as a GSM modem for PC fax,
Connections 9
data and SMS services. For this specific
configuration, please refer to the FCT Data
Reference Manual. See Accessories on page 41.
Installing an FCT connected to a PBX
The FCT is designed to provide a telephone line
(RJ11 connector) that behaves in the same way as an
analog trunk.
Generic requirements
The PBX should meet the following generic
requirements for FCT connectivity:
• The PBX must provide analog trunks. Otherwise,
the ISDN FI12 adapter accessory will be necessary.
See Accessories on page 41).
• One position of the trunk must be assigned to each
FCT terminal.
• The trunk card must support either Busy Tone
Detection (BTD) or Polarity Reversal Detection on
answer and release.
• The PBX can be programmed to utilize Least Cost
Routing (LCR), if available, to automatically choose
the FCT trunk when suitable.
• If the PBX does not offer LCR, choose the FCT
trunk manually with a special dialed prefix.
The F251m terminal is compatible with most analog
PBXs on the market and with most of the available
2B+D ISDN digital output trunks, via its accessory
ISDN FI12 adapter. See Accessories on page 41.

To carry out a correct FCT installation in a PBX,
please follow the FCT installation instructions
(Preparing your FCT and Installing the FCT on the
wall) and then refer to Using PBX on page 23.
Note: a minimum distance of 3 meters between the
FCT and the PBX is recommended. The cable
distance between the PBX and the FCT should not
exceed 600 meters, and the connection cable should
be at least 0,4 mm
2
.
Warning!: if you install more than one FCT to a
PBX, their antennas have to be separated by 20 cm
in height or 2 meters in horizontal.
Preparing your FCT
You need to follow these steps before you install the
FCT on the wall and make all definitive connections.
Warning!: the FCT should be switched off before
inserting or removing your SIM card or connecting
any devices to the FCT.
Assembly
1. Connect the antenna
2. Remove the front cover, pressing down and
pushing the small tab that is in the center of the
bottom part of the FCT. Open the SIM Card
holder shifting the mobile part of the holder and
the rotating it to place the connector upwards.
Connections 11
3. Close the SIM Card holder, placing it horizontally
and assuring it with the holder mobile part.
4. Optionally install the battery on the battery
compartment (over the SIM Card). To do so,
connect the battery cable to the FCT connector.
Connect the black cable to the negative pole of the
battery, and the red cable to the positive cable.
Fit the cable under the holding tab (over the SIM
Card) and insert the battery until it is hold by
the tab.
5. Place the front cover back in its previous position.
Connect a telephone to the FCT
Connect a fixed telephone to the FCT telephone line.
Important: you will use this telephone to dial the PIN.
Switch on the FCT
Connect the power supply. The FCT switches on
automatically and the green and red light indicators
start flashing.
Enter PIN
Most SIM cards are protected with a PIN (Personal
Identity Number), which you get from your network
operator and which you need in order to access the
network.
If the SIM card is not protected by a PIN code, then
you do not need to enter the PIN. The FCT starts the
network search automatically.
If the SIM card is protected by the PIN code, then the
green and red lights will flash simultaneously.
Note: if you have the DA20 display adapter
accessory (See “Accessories” on page 41), an
“ENTER PIN” message will show on your display.
Please follow these steps to enter the PIN:
• Pick up the telephone and dial the PIN code. Press
the # key on your telephone or wait until you hear a
beep tone.
• If you make a mistake while entering your PIN,
hang up the telephone immediately and try again.
12 Connections
If the PIN is correct, you will hear a beep over the
telephone (positive indication tone). If it is incorrect,
a deep tone will sound (error indication tone).
If the PIN is entered incorrectly three times, the SIM
card will be blocked. If this happens, you can
unblock it by using the PUK (Personal Unblocking
Key), which you also get from your network operator.
See SIM card security on page 33.
Note: once you have entered the PIN code for the
first time, you will not have to enter it again unless
you change your SIM card. The FCT performs this
operation automatically in case of power failure.
Network search
After you have switched on your FCT and entered the
PIN, the FCT automatically searches for a network.
Note: if the red light is off, there is a problem with
the power supply. See “Troubleshooting and FCT
indicators” on page 35.
When a network is found, the green light switches on
or flashes depending on the GSM signal strength. See
Light indicators on page 35.
Note: if the green light is off, you do not have access
to the GSM network at your present location.
Now you have prepared the FCT for wall installation.
Please, follow the instructions below for complete
wall installation.
Installing the FCT on the wall
FCT Location
The GSM signal strength available at the FCT
location affects the performance of the unit. The
stronger the GSM signal, the better the FCT
performance.
T
ip: test several potential locations by moving the
FCT while looking at the green light . Select the
location where the green light is steady, or the
location with the highest amount of flashes.
Note: moving the FCT as little as 20 cm can affect
the GSM reception quality.
Connections 13
Location Testing
Number of Green Light flashes Location status
0 Unacceptable
1 - - - Acceptable
2 - - - - - - Good
3 - - - - - - - - - Very good
Steady ------------------------------- Excellent
Please consider the following recommendations:
• Always select an indoor location, preferably close
to a window and the roof. Generally, you will
experience better GSM signal strength in these
places.
• Do not install the FCT in a bathroom, a wet or
damp basement or an outdoor location.
• Do not install the FCT on walls or rooms that
contain large amounts of metal, steel or wiring.
• Do not expose the FCT to extreme temperatures
(near radiators, cooling vents, etc).
If you experience poor reception quality, an outdoor
antenna may result in improvement. See Accessories
on page 41.
Wall mounting
Please proceed as indicated in the following picture.
1) Fix the wall-mounting bracket on the wall
2) Insert the FCT in the wall-mounting bracket
14 Connections
3) Shift the FCT down
Warning!: once you have fixed the FCT to the wall
and switched it on, check the final status of the red
and green lights. If either one is off, there is a
problem with the power supply or the GSM signal.
See “Troubleshooting and FCT indicators” on
page 35.
Now the FCT is ready for connecting devices and
making calls.
Note: if you want to remove the FCT from the wall
bracket, then you have to press the flap (step 1) as
indicated in the following picture and then shift the
FCT upwards (step 2).
Connecting fixed line devices
Connect the fixed line devices to the FCT (telephone
line connector) with telephone wire in the same way
as with an analog telephone line.
Fixed line devices are connected in parallel. You can
connect the devices directly to the FCT telephone line
connector (RJ11) or make an internal telephone
wiring, use RJ11 splitters or similar connectors.
Connections 15
Note: when making the connections, the two-wire
telephone cable polarity does not affect at all.
T
ip: if your house or company is already wired with
telephone cable, you only need to connect the cable
to the FCT RJ11 connector and your telephone line
will be up and running in all rooms.
Note: it is strongly recommended that the telephone
wire is installed indoors in order to avoid lightning
damage.
Note: the telephone wire should not exceed 600
meters. Larger distances can be achieved by using
high quality telephone wire.
Checking connections
Once the fixed line devices (1 up to 3) have been
connected, make the “Ring Back Test” as follows in
order to check the connections:
• Lift one telephone and dial **#10#. You will hear a
beep tone (the FCT red and green lights will start
flashing - three flashes synchronized).
• Hang up the telephone and check if all the
connected telephones start ringing.
• Lift any of the telephones connected and then hang
it up again. The ringing will stop (the red and green
lights will go to normal operation mode).
T
ip: if any of the telephones has not been ringing,
check your telephone cable layout and connections to
make sure that all devices are properly connected.
Checking the calls quality
Use any of the telephones connected to the FCT to
make a call. Check the speech quality and ask the
receiver to call you back to confirm that you can also
receive calls.
If you have problems, see Troubleshooting and FCT
indicators on page 35.

Using telephones
Fixed telephones connected to the FCT telephone line
work in the same way as if they were connected to a
fixed network.
Warning!: you will not be able to make or receive
data or fax calls while a speech call is ongoing.
Note: you can also benefit from some FCT
functionality that you do not usually have on your
fixed network. See Advanced features on page 24.
You can find detailed information about the tones that
the FCT sends on Audible tones page 38.
Using telephones 17
Using CLI displays
Devices that display the incoming number (telephones
with display, external displays, etc.) can be directly
connected to the FCT line interface in the same way
as an ordinary telephone. If your subscription includes
the Calling Line Identification (CLI) service and the
caller´s network sends the number, the FCT will send
the caller´s number towards your CLI display.
In general, your FCT will be programmed (according
to your country specifications) to send the CLI
information with the right standard so that your CLI
device works properly.
Refer to your CLI telephone or display user guide for
further explanations on your CLI indications.
T
ip: if you run the Ring Back Test on page 16
(lift the telephone, dial **#10# and hang up), you can
check if the following number “1234567890” appears
on your CLI display. If it does not, the FCT is not
using the right standard.
If you experience that your CLI device is not
showing the calling numbers, you may need to
change the FCT settings.
This is done by dialing one of the following
sequences, depending on the CLI standard that your
CLI device supports (check its user guide).
CLI standard Dialing sequence
ETSI DTMF **0002*1#
ETSI V.23 **0002*2#
Bellcore **0002*3#
T
ip: if you cannot figure out which CLI standard to
use, try all three sequences, following each of them
by a Ring Back Test. The CLI standard whose Ring
Back Test prints a “1234567890” on your display will
be the correct one.
In order to disable the CLI Display functionality and
therefore stop viewing calling numbers, dial
**0002*0# from a DTMF (Pulses) telephone
connected to the FCT.
T
ip: if you do not want your telephone number to
appear at the caller’s location, you can dial #31#
before the phone number you are going to call
(B-number); in other words, dial #31#B-Number.
To find out about the DA20 accessory display, please
check Accessories on page 41.
