Checking the calls quality:

Telephone
Display
Fax
PC modem
Note: remember that you do not have to worry about the two
wire Telephone cable polarity when making connections; if the
two wires are reversed the FCT and the fixed line devices are
not affected at all.
Tip: 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.
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 light indicators will start
flashing -three flashes synchronized).
Hung the telephone up and check if all the connected
telephones are ringing.
Lift any of the telephones connected and then pick it up
again. The ringing will stop (the red and green lights will
go to normal operation mode).
Tip: 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.
