3.1 Telephone (TEL) Cable Test Mode

The SOHO Tester assumes that the
6-position jack on the main unit and the
remote will be used for connecting the
tester to the cable run you want to test.
This mode uses the 3-pair USOC standard
to define the pairs. Connector pins 1–6,
2–5, and 3–4 are the pairs defined by this
standard. The tester will display the PASS
icon when all 6 pins are correctly wired in a
one-to-one order. If all 6 pins are correctly
wired in the reverse order, the PASS icon
and a flashing REV icon will appear.
Standard telephone cables used between a
phone set and a wall jack are usually
reverse-pinned.
