INPUTS AND AUTOMATIC SWITCHING
The TALAN provides modular 8 type connectors (Line, Phone), banana plug connectors
(Black/Ring, Red/Tip, Green/Earth), an expansion port (for future applications), and an RF
antenna input.
The Expansion port will be used for future upgrades as developed, but currently has NO
function.
Warning: Even though the Expansion port is currently unused, it is still connected to the
test input circuitry. Devices other than those provided by REI should NEVER be attached
to this connector.
The RF Antenna port is used for RF broadband analysis using the 2 provided antennas.
The banana plugs can be used for any type of miscellaneous testing.
Warning: The TALAN circuitry is designed for testing sensitive phone networks and
equipment. The banana plugs should NOT be connected to high current or high voltage
test points such as power outlets.
The modular 8 connectors provide for switching between selected pairs for most types
of wiring. For example, if a cable has 8 conductors, the typical wiring pairs are as follow:
4:5 is typically the primary pair.
3:6 is the secondary pair
1:2 is an auxiliary pair
7:8 is an auxiliary pair
Using these 8 conductors, it is important to note
there are 28 possible combinations to consider.
For example:
1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8
2:3, 2:4, 2:5, 2:6, 2:7, 2:8
3:4, 3:5, 3:6, 3:7, 3:8
4:5, 4:6, 4:7, 4:8
5:6, 5:7, 5:8
6:7, 6:8
7:8
With TALAN 3.0, conductors 1:8 can also be tested against the Shield on the MOD8 connector,
and also against the EarthGround Banana Jack Connector.
