Notes
Test Jacks Terminated Circuit is broken when plug is inserted into
jack. The test equipment is normally set to
“Terminate” and provides 75 Ohm
termination.
Monitor Jacks Monitor The circuit is not interrupted when the plug
is inserted into the jack. The test set, when
set to “Monitor”, provides a 75 Ohm
connection, and expects the signal to be
20 dB lower than the original signal.
Direct
Connection to
“Punch Down
Block”.
Bridged The circuit is not interrupted in this mode.
The test set impedance is greater than 1000
Ohms so that the circuit is minimally
affected. Test set is set to “Bridged.”
