ATPC threshold as low as possible to reduce the time that ATPC is active. Current timer status is
available on the ATPC Statistics Page
. There are event log entries for all timer events.
• Receiver Overload Protection is similar to ATPC. It ensures that the maximum RSL is not
exceeded by reducing transmit power of the far-end radio so that radio specifications are met.
Receiver Overload Protection reduces far-end transmit power in un-faded conditions, or during
up-fades, to ensure that the maximum input RSL specification is met at all times and not
overloaded.
Receiver Overload Protection and ATPC can run independently or simultaneously. The radio runs
at standard transmit power levels as long as the Overload Protection RSL threshold is not
exceeded. If exceeded, the radio reduces the far-end transmit power to maintain the target RSL.
For links that normally run at a value exceeding radio specifications, use the maximum output
power in the System Configuration setting and enable Receiver Overload Protection to attenuate
the value for normal conditions and restore output power during fades.
• Set the RSL High Watermark Event Trigger value to a few dB above the normal (un-faded) RSL
link or to a value at or above -33dBm, whichever is higher, to minimize the number of entries in
the event log caused by running at or near the maximum RSL specification.
Note: Ensure that radio implementation meets local regulations. There may be limitations to
the use of the Receiver Overload Protection feature. Consult your local regulatory authorities.
