Configuring ATPC and ATPC 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, IP-20 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 protection, the ATPC override state is propagated to
the standby unit in the event of switchover.
Notes:
When canceling an ATPC override state, you should ensure that the
underlying problem has been corrected. Otherwise, ATPC may be
overridden again.
You cannot use ATPC in MIMO mode. See
To enable and configure ATPC and display ATPC settings:
1 Select
Radio > ATPC
. The ATPC page opens.
◦
For multi-carrier units, the Radio Parameters page initially displays a table
as shown in
◦
For single-carrier units, a page appears, similar to
(which shows
an IP-20C/IP-20C-HP page).
