The frost line is the depth to which water in the soil will freeze in the winter. You should know this before you lay your cable down, water expands as it freezes and will cause damage to your communications investment.
The frost line will vary depending on your location and can range from 3 to 6 feet. An easy way to determine your line is by examining a frost line map.
National frost depth maps are only a reference, you should check with your local building inspector for a more accurate measurement for your area.
I hope this has shed some more light into the "Minimum" term of your burial cable depth. Measure twice cut once!
