Configuring an FRM with FRI-V.35 Back Card
Most configuration tasks for the FRM follow standard IGX module configuration procedures. However,
the FRM with FRI-V.35 back card differs in the effect that module firmware models and number of
operating ports has on maximum throughputs for each port, and in the way the FRI-V.35 back card
handles data clocking. For information on calculating maximum throughput for your specific usage
situation, see the “Calculating Maximum Throughput for Different FRM Firmware Combinations”
section on page 2-70. For more information on data clocking on the FRI-V.35 back card, see the “Data
Clocking on the FRI-V.35 Back Card” section on page 2-71.
Calculating Maximum Throughput for Different FRM Firmware Combinations
The maximum throughput for the FRM using the FRI-V.35 back card depends on the number of
activated ports (see Table 2-43).
