FCT connectivity to the ISDN 2B+D trunk of the PBX
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 18.
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

.
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.
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.
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.
