ROSA Element Management System
To monitor the amplifier, a transponder must be installed in the amplifier. This
transponder will communicate back to the headend through the reverse path. The
transponder signal is received at the test point at output. See Overview Diagram on
page 1-2.
The level measured by the transponder will be attenuated by approximately 40 dB
relative to the output signal at output. The transponder transmitter level is adjusted
to the same level as the other reverse signals. The level from the transponder will be
attenuated by approximately 30 dB when injected at the reverse path.
Use a handheld terminal which contains the necessary driver for the unit to set up a
transponder. New drivers can be installed by means of downloading the kit
A91210.10.
