4.2 Cable Test Modes
In most modes, the tester is constantly testing and
reporting results. While we recommend that an
unknown jack connection always be verified by
connecting to the tester while it is powered off, you can
attach a known dead network cable or jack to the tester
while it is running. In that case, a test will most likely be
in progress when a cable connection is made.
The results of the test in progress at connection time are
unreliable. You should press the SEL button to
terminate the current test and initiate a new test.
4.2.1 J
ACK
ID
The Jack ID test identifies what equipment, if any, is
connected to the other end of the jack or cable you are
testing. The test first looks for voltages present on the
connector pins. If voltages are found in typical phone
locations, tests for current levels and dial tone are run.
From these tests, the LAN Solution Network Tester will
report voltage or phone type found.
