Thresholds 2
The
Thresholds 2
tab allows you to set
additional threshold values.
Each parameter is described below:
³
Min. VF Long. Balance(dB)
defines the minimum voice
frequency threshold longitudinal
balance level. Specify a value
between
10
and
80
.
³
Max. VF RMS Noise
defines the maximum threshold RMS noise energy
level. Specify a value between
-90
and
10
dBm if the ITU standard is
used. Specify a value between
0
and
100
dBrn if the ANSI standard is
used.
³
Max. VF Power Influence
defines the maximum threshold power
influence level on the circuit. Specify a value between
-90
and
20
dBm
if the ITU standard is used. Specify a value between
0
and
110
dBrnC 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.
