12.4 Range Adjustment Curves
Use these graphs to look up the link Range and find the Throughput Factor that must be
applied to adjust the 0 km data throughput rates for the required combination of Link Mode
Optimization (IP or TDM) and Link Range (km).
Curve A (Figure 120) is used when one of the following conditions applies:
•
Link Symmetry = 3:1
•
Link Symmetry = 1:1 and Link Optimization = IP
•
Link Symmetry = 1:3
Curve B (Figure 121) is used only when Link Symmetry = 1:1 and Link Optimization = TDM.
