Thresholds 2
The Thresholds 2 tab allows you to set
additional threshold values.
Each parameter is described below:
³
Min. Long. Balance(dB) defines
the minimum voice frequency
threshold longitudinal balance
level. Specify a value between
10 and 80.
³
Max. Noise Metallic (dBm) defines the maximum threshold RMS
noise energy level. Specify a value between -90 and 10 if the ITU
standard is used. Specify a value between 0 and 100 if the ANSI
standard is used.
³
Max. VF Power Influence (dBm) defines the maximum threshold
power influence level on the circuit. Specify a value between
-90 and 20 if the ITU standard is used. Specify a value between
0 and 110 if the ANSI standard is used.
³
Min. WB Long. Balance(dB) defines the minimum threshold
wideband longitudinal balance level. Specify a value between
10 and 80.
³
Attenuation(dB) defines the threshold wideband attenuation level.
Specify a value between 0 and 80.
To set a threshold value:
1. Press the up/down arrow keys to highlight the desired parameter.
2. Press to select the value.
3. Press the left arrow key to erase the existing value, and then use the
alphanumeric keypad to enter a value. To cancel the entry, press .
4. Press to accept the value.
