Copper Test Module 61
4 POTS Auto Test
The purpose of the POTS Auto Test function is to detect the DC current and
measure the voice frequency in a copper telephone loop. This test allows
you to compare measured results against stored threshold values to
provide pass or fail status results of the POTS circuit type.
To view POTS Auto Test tabs:
From the POTS Auto Test pane use the F1, F2, or F3 key to view the various
tabs.
Thresholds
The Thresholds tab allows you to set threshold values for the
POTS auto test.
Each parameter is described below:
³
Min DC Current (mA) is a value
ranging from 10 to 100. Default is
23.
³
Max Loss (dB) is a value ranging
from 0 to 50. Default is 8.
³
Max VF Power Influence is a value
ranging from -90 to 10 dBm with a
default of -10, if the ITU Standard is used. If ANSI Standard, the range is
from 0 to 100 dBrn with a default value of 80.
³
Max VF Noise is a value ranging from -90 to 10 dBm with a default
of -70, if the ITU Standard is used. If ANSI Standard, the range is from
0 to 100 dBrn with a default value of 20.
³
Min Long Balance (dB) is a value ranging from 0 to 100. Default is 60.
