Running a Call Waiting Caller ID Test
The Call Waiting Caller ID test enables the tester to place a call on the test line
to a Quiet Termination, wait to be called from another line, then capture and
display Caller ID information sent on the line by the C.O. switch.
After you have select the Call Waiting Caller ID function and dial (either
automatically or manually) a C.O. Quiet Termination (or other quiet line) as
described earlier, the tester waits indefinitely (in the off-hook condition) for an
incoming call from another line.
If the test line is equipped with the Call Waiting Caller ID feature, the tester
detects the incoming Caller ID information (sent by the C.O. switch), and then
displays the received Phone number along with the associated Name, Date, and
Message (if included).

If the test line was not equipped with the Call Waiting Caller ID feature, the
tester continues to wait for incoming data. If the Caller ID data was garbled,
the tester displays an error message.

Running a Line Monitor Function
The Monitor Line function provides a high-impedance, non-intrusive method
for monitoring the audio status of a spare or working POTS pair. It is not
technically a Dial-Up test, but is most often used on working POTS lines, and
is therefore included in this group.
1. Select
Monitor Line
in the POTS Toolbox, press
L
.
The tester’s internal speaker is connected to the test line at this point, with
a “Monitor Enabled” message displayed on the screen.
2. To stop the Monitor function, press
K
or
M
.
