1.1.6 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.
Use the worksheet in Table 2 to calculate the maximum dB loss of circuit. Use the
worksheet in Table 3 to calculate maximum DC loop resistance.
NOTE
Loop limits are for a circuit with 6 dB nominal margin at 68° F.
