After a one second pause, the test begins automatically and results appear on the screen.
10 Press the right arrow to move to DC Current.
This test checks for continuity and checks for proper loop current for POTS lines (to verify if
enough current is present to operate equipment including the phone or caller ID boxes).
After a one second pause, the test begins automatically and results appear on the screen.
11 Press the right arrow to move to Balance.
Balance is a number representing the quality of the telephone circuit and the degree to which
the Tip (A) and Ring (B) conductors are electrically the same in their ability to cancel noise.
The balance measurement is used to identify poor loop quality or cable bonding and
grounding issues that allow excessive loop noise.
After a one second pause, the test begins automatically and results appear on the screen.
12 Press the right arrow to move to Load Coil.
The SmartClass Triple Play Services can detect up to five load coils that may exist on the line,
out to 27,000 (8,200 meters) feet. It will also report a short, open, or a high noise condition, if
detected. For accurate load coil detection, disconnect the pair from the CO/exchange to
remove CO battery/wetting current. Although the detector will work with voltage on a pair,
accuracy will be reduced. In addition, the detector works best when the last coil is followed by
at least 1200 feet (336 meters) of cable.
After a one second pause, the test begins automatically and results appear on the screen.
13 To save a test report, press the utility (i) key and then select Save Report, and then specify
the report settings such as report name, report format, technician ID, location, and other
settings as needed.
To learn what your results mean, see “Copper results” on page 135.
You are finished performing measurements.
NOTE:
When measuring from Tip (A) or Ring (B) to Ground (E), you should connect the Ground (E) lead
to the shield (ground), and be sure to enter the fill type (in the COPPER SETUP menu) or the
distance will not be accurate. If you connect to some other ground that is not parallel to your pair,
and do not enter the appropriate fill type, this measurement will be inaccurate.
NOTE:
A ground connection is required to measure balance.
