Telethon 3G Front Panel Features
The Telethon 3G is used as a set of two units. The inputs to one unit of the pair are received
by the second unit and appear as the corresponding outputs. Unit one SDI/DATA Inputs 1-4
are reflected on Unit Two as SDI/DATA Outputs 1-4. Similarly the fours fiber inputs on Unit
One are reflected as the four fiber outputs on Unit Two. Inputs to Unit Two are therefore
reflected in the same way on Unit One.

There is no requirement that all connectors be active. For example, if you are using BNC
Inputs 1 and 3,but you are skipping Input 2, the output on the opposite unit will be on
Output 1 and Output 3.
The Telethon 3G provides no user-accessible adjustments: the unit is a pass-through device
with selectable monitoring capability.
