determine the source of the excessive clutter, and correct the problem before burying the cable.

Note The maximum dynamic range over the full cable length is 20 dB. If any
section of cable has a dynamic range greater than 10 dB over 10 m,
adjustments must be made to the installation (e.g., add ferrite beads).
