Faunus BT-10 Instruction Booklet
BT-10 Telephone
& Modem
Line Tester
-Instruction Booklet-
The BT-10 is designed to test a
variety of telephone line parameters.
It can help prevent needless and
expensive telephone company
service calls and can safeguard your
equipment by testing one or two line
installations for proper operation of:
◊ Tip to Ring DC Polarity.
◊ Relative DC Line voltage level.
◊ Line Loop-Current capacity.
◊ Relative AC Ring voltage level.
◊ Phone extensions and cords.
These features can simplify the
testing and installation of modular
phone jacks and phone line wiring.
Step I.
Inserting the Adapter
When you remove the cap from the
unit, an adapter cord is pre-installed.
It can be replaced or removed for the
testing of extensions and cords.
Begin by inserting, as shown, any
end of the included adapter (A) into
the modular RJ-11 Jack (A). Slide
the Line 1/ Line 2 Selector Switch to
the position of which line you are
testing. If you are not sure, it’s
simple, just follow the next steps.
Step II.
Connecting to the Network
It is best to begin testing at the
primary entry point of the local
telephone line (Network Interface
Test Jack). In this way you can
determine if any problem is due to
your provider or your own local
installation. As shown, insert the free
end of the adapter (B) into the
modular RJ-11 telephone jack under
test or Network Interface Test Jack
(B).
