HDSL Tables and Worksheets
The following section includes tables and worksheets to calculate dB loss and DC
resistance for HDSL local loops. The information is intended to give the user a
guideline when engineering and deploying new circuits or analyzing existing circuits
against HDSL criteria.
to calculate the maximum dB loss of circuit. Use the
to calculate maximum DC loop resistance.
NOTE
Loop limits are for a circuit with 6 dB nominal margin at 68
°
