configuration will be reverted in case of erroneous configuration changes
applied.

section both for local and remote side CFIP Lumina.
4.1.2 ATPC Configuration
To configure ATPC, it is necessary to set Rx (remote) “min” and “max” values and enable
the ATPC feature.
ATPC update period and ATPC delta are recommended to be left unchanged.
It is also possible to change the limit of Tx power correction.
1.
ATPC function
– allows enabling or disabling ATPC (Automatic Transmit
Power Control). By default this feature is disabled (command line
–
atpc
[enable|disable]
);
2.
ATPC update period (1..5)
–
allows defining the period in seconds in which
ATPC parameters are being updated. By default the update period is 1
second (command line
–
atpc delay
<power change delay time 1..5 sec>
);
3.
ATPC delta (1 .. 5 dB)
– allows defining ATPC delta - an increment or
decrement in which Tx power will be changed. It is highly unadvisable to
change this parameter (command line
–
atpc delta
<tx power correction step
1..5 dBm>
);
4.
Tx power correction
– displays the amount of transmitter power in decibels
ATPC has currently corrected (command line
–
atpc status
);
5.
Tx power correction limit (-19..-1 dB)
– allows defining the amount of dB
ATPC will be able to correct regarding initial Tx power value (command line
–
atpc limit
<tx power correction limit -19..-1 dB>
);
6.
Remote device status
– shows if management CPU was able to read data
from remote management CPU;
7.
Rx (remote) level maximum (-50..-20 dBm)
–
allows defining the maximum
Rx level. ATPC Tx power correction will be performed only in case of
exceeding this defined maximum Rx level (command line
–
atpc rxmax
<rx
level max -50..-20 dBm>
);
8.
Rx (remote) level minimum (-90..-45 dBm)
–
allows defining the minimum Rx
level. ATPC Tx power correction will be performed only in case of exceeding
this defined maximum Rx level (command line
–
atpc rxmin
<rx level min -
90..-45 dBm>
);
9.
Pressing “Execute configuration” applies changes made to the corresponding
section only for the local side CFIP Lumina
. If “Rollback on” is selected,
(!)
Note, that ATPC is mechanism for reducing Tx power, that‟s why to make proper use of ATPC,
transmitter power (Tx power) must be set to the maximum value.
