The range is from 13 to 50 dBm using a 0.25 dBm resolution. If the entered value
is not compatible with the installed ODU, a trap will be issued. If the entered
value is below the minimum supported by the ODU the actual power will be set to
the minimum supported by the unit. If the entered value is above the maximum
supported by the ODU, the power will be changed to the maximum value
supported by the ODU .
The default is 28 dBm.
If the Diversity Mode is set to Fourth Order Diversity, the Tx Power of the ODUs
associated with Channels 2-4 will be forced to the value configured for the ODU
associated with Channel 1.
If the Diversity Mode is set to Second Order Diversity, the Tx Power of the ODU
associated with Channel 2 will be forced to the value configured for the ODU
associated with Channel 1. Channels 3 and 4 are not used in Second Order

4.7.5 Frequency Bands File and Frequency Bands
Groups
The Frequency Bands Configuration file defines the characteristics of each of the
frequency bands supported by the system. These characteristics include:
Lowest Downlink Frequency
Highest Downlink Frequency
Step (resolution)
Duplex Separation: the difference between downlink (Tx) and uplink (Rx)
frequencies. In systems operating in TDD mode the Duplex Separation is 0.
Group ID: In certain cases, an AU can be connected to ODUs using different
Frequency Bands. The Group ID defines the Frequency Bands Group, which
includes all the Frequency Bands that can be used by the same AU. An AU
cannot be associated with two or more ODUs that use Frequency Bands
belonging to different Groups.
