The block of bits at the left of the screen represents the upstream
signal. The highest frequency for the upstream is approximately
140 kHz. The higher frequency group at the right represents the
downstream signal. There can be anywhere from a 20 to 40 kHz
buffer between the upstream and downstream frequencies. As
mentioned earlier, the lower frequency tones (lower than 140
kHz) represent the bandwidth used for the upstream signal. The
higher frequency tones at the right show the frequencies used for
the downstream signal. The bits should drop to zero around 140
kHz. This is the buffer between the upstream and downstream
signals. The actual size of this buffer varies. If you see a major
drop in bits in either the downstream or upstream section, this
may have been an indication that there is an interferer at that
frequency. For example, if there is a major drop at 772 kHz, this
most likely represents an interfering T1 signal.
