Thresholds

The Thresholds tab displays the
threshold parameters for the Inactive
Pair Test. They are part of the CQ
profile and cannot be edited on this
pane.

Each parameter is described below:

³

Max. AC Voltage T-R (V) is the
maximum AC threshold voltage for
the T-R leg of the circuit.

³

Max. AC Voltage to GND (V) is the maximum AC threshold voltage to
ground for the circuit.

³

Max. DC Voltage T-R (V) is the maximum DC threshold voltage for the
T-R leg of the circuit.

³

Max. DC Voltage to GND (V) is the maximum DC threshold voltage to
ground for the circuit.

³

Min. Metallic Insulation (MOhm) is the minimum threshold
resistance for the circuit.

³

Max. Opens Variance (%) is the percentage maximum capacitance
balance.

³

Max. Noise Metallic (dBrnC) is the maximum level of voice frequency
noise.
