The Tone Receiver screen is divided into areas making it easy to monitor all settings and received signal levels.
The following image identifies the information on the screen.
The
F1
key is used to select one of the control options. Function keys
F2
and
F3
decrease or increase the current
option. The Gain and Volume values are in the top corners of the analog meter area. The
F4
or
PWR/CLR
keys
can be used to exit to the Home screen.
The SR-101 receiver software and hardware can detect small differences in received tone amplitude that cannot
be heard. The received signal strength is displayed on an analog scale of 0 to 10. The equivalent numeric value of
0% to 100% is displayed in the lower right corner of the meter area.

Simplex tone has been used extensively to identify cable pairs for cable transfers and restoration. Simplex tone
applies equal amplitude and phase tone on the Tip and Ring at the same time. The customer does not hear the
tone because there is no signal difference between the Tip and Ring on balanced pairs. Simplex tone is
sometimes referred to as “quiet tone”
and is ideal when identifying cable pairs.
Simplex tone couples over to adjacent pairs. This helps identify pair groups, and then the specific pair, because
the tone becomes louder when the probe is placed near the pair. Cable conditions can increase tone coupling
making positive pair identification difficult.

TriPlex tone
,
a special tone mode developed by AALogic. TriPlex is recommended when cable conditions, such as
poor shielding, bonding, or cable faults produce excessive tone coupling. TriPlex can be heard by customers and
is intended to be used for service restoration when the technician has difficulty identifying pairs.
