OneCheck POTS Closeout
This test offers a quick and easy way to check if a line is usable for POTS (5-point closeout).
It is accessed via its own icon on the home page under the OneCheck Copper section. The
OneCheck POTS Closeout is available to all ONX-580 products and does not require any option.
1. Press the OneCheck POTS Closeout icon to open the configuration screen.
2. The Tone Phone Number and the Quiet Line Phone Number are blank in the
beginning. You need to enter them for the test. The Start button is grayed out until
they are both selected. The Use Same Number for Tone / Quiet Line check box is
unchecked by default.
When this check box is unchecked, and you change the Tone Phone Number , two
different numbers will be displayed. If the box is
checked, it will assign the tone phone number to the
quiet line phone number (phone numbers are numeric
only, commas will produce a 1 second pause)
3. Once you selected the phone numbers, press the Start
button. The next screen displays the running tests.
4. There is a battery check that will be required to pass
before the rest of the testing proceeds. The battery
check ensures that there is +/- 25 VDC on T/R (or A/B).
If the battery check fails, you will receive a message,
offering to retry the battery check or abort the test.
Aborting the test will not allow you to save the results.
5. The following test results with pass/fail indicators will
be displayed: DC current (mA), narrowband loss (dB),
circuit noise (dBr nC), power influence (dBr nC) and
balance (dB). Press the Show Details button for more
information.
