Configuring ATPC and Override Timer
ATPC is a closed-loop mechanism by which each carrier changes the TX power according to the indication received
across the link, in order to achieve a desired RSL on the other side of the link.
With ATPC, if the radio increases its TX power up to the configured TX power, it can lead to a period of sustained
transmission at maximum power, resulting in unacceptable interference with other systems.
In order to minimize interference, PTP 820G and PTP 820F provides an ATPC override mechanism. When ATPC
override is enabled, a timer begins when ATPC raises the TX power to its maximum. When the timer expires, the
radio enters ATPC override state. In ATPC override state, the radio transmits no higher than the pre-determined
ATPC override TX level, and an ATPC override alarm is raised. The radio remains in ATPC override state until the
ATPC override state is manually cancelled by the user (or until the unit is reset). The radio then returns to normal
ATPC operation.
In a configuration with unit redundancy or radio protection, the ATPC override state is propagated to the standby
unit or radio in the event of switchover.
Note
When canceling an ATPC override state, you should ensure that the underlying problem has been
corrected. Otherwise, ATPC may be overridden again.
To enable and configure ATPC and display the ATPC settings:
