The drop line length is the line length between a branch point on the trunk
line to the farthest node that is located on the drop line.
The maximum drop line length is 6 m. A drop line can be branched out into
other drop lines.
The total drop line length is a total of all drop line lengths.
The total drop line length must be within the allowable range and even
then, each drop line must be 6 m or less.
The allowable range of total drop line length varies with the baud rate as
shown in the following table.
Baud Rate (kbps) Total Drop Line Length (m)
500 39 max.
250 78 max.
125 156 max.
