2.5.3 General Tx Parameter
Defined Max Tx Power
Range (dBm)
The available range for the Maximum Tx Power parameter for the
applicable modulation level(s).
The minimum value for the Maximum Tx Power is -10 dBm. The
maximum value depends on several unit properties and parameters:
 The HW revision of the unit
 The Maximum Allowed Tx Power as defined for the applicable
Sub-Band.
 The Maximum EIRP as defined for the applicable Sub-Band,
together with the value of the Antenna Gain. In certain countries
the Maximum EIRP of some equipment types cannot exceed a
certain value. In these cases the Transmit Power cannot exceed
the value of (Maximum EIRP - Antenna Gain).
Max Tx Power (dBm) The maximum transmit power for the applicable modulation level. For
each modulation level, the unit will use as maximum transmit power
the minimum between the configured Maximum Tx Power parameter
and the maximum Tx power allowed by the HW and the Country
Code for the specific modulation level.
Tx Control Applicable only for AU and BU. This option enables turning off/on the
device's transmitter, or having the Tx status controlled by the status of
the Ethernet port/link.
If the selected option is Ethernet Status Control, then the device will
transmit as long as the Ethernet link is up. If the Ethernet link is down,
the transmitter will be switched off.
This feature can be used during maintenance or testing to avoid
transmissions using undesired parameters.
The parameter is available only when managing the unit from its
Ethernet port.
Transmit Power (dBm) The transmit power of the unit when using modulation level 1 (for
other modulation levels the actual transmit power may be lower due
to HW limitations). For AU/BU, this is the fixed transmit power level
and is not part of the ATPC algorithm. For SU/RB, this is the fixed
transmit power level when the ATPC algorithm is disabled. If the
ATPC Option is enabled, the value configured for this parameter
serves for setting the initial value to be used by the ATPC algorithm
after either power up or losing synchronization with the AU/BU.
The range is according to the Available Range for Modulation Level 1
in the Transmit Power Table.
