frequency bands supported by the system. These characteristics include:

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.

In the current release, the following Frequency Bands are supported:

In sectors with diversity (either second or fourth order diversity), new 2.x GHz AU-ODUs with HC08 
revision 137 (HW ready for 10 MHz bandwidth), cannot be connected to the same AU-IDU together 
with older AU-ODUs with HC08 version 134. All AU-ODUs connected to the same AU-IDU must use 
the same HC08 version.
