F251m
The F251m is a flexible and cost-effective solution
for connecting your SoHo telephone system to the
digital wireless GSM network.
When there is no fixed infrastructure or if you need
additional telephone lines:
• install the terminal
• run cabling from the F251m to any place within
your Small office Home office (SoHo) and
• you will be ready to connect and use standard
telephones, fax machines, computers (Internet) and
PBXs
The terminal features the latest technology, which
makes it perfect for everyday communication:
• Triple band GSM (E-GSM 900, GSM 1800, GSM
1900)
• Telephone line providing high quality speech
(EFR), G3 fax and up to V.90 data transmission
• GPRS (General Packet Radio Service), which keeps
you always on and facilitates rapid transmission of
data (ideal for e-mail and Internet browsing)
• HSCSD (High Speed Circuit Switched Data), which
further enhances data transmission
• Embedded modem available over the RS232 port
• Battery back-up

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.

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,
