Quadrature (IQ) samples between the O-DU and O-RU within the O-RAN
architecture based on functional split 7.2x. The library defines the
O-RAN packet formats to be used to transport radio samples within Front
-Haul according to the O-RAN Fronthaul specification. It provides
-functionality for generating O-RAN packets, appending IQ samples in the
-packet payload, and extracting IQ samples from O-RAN packets.
+Haul according to the O-RAN Fronthaul specification. refer to *Table* 2.
+It provides functionality for generating O-RAN packets, appending IQ samples
+in the packet payload, and extracting IQ samples from O-RAN packets.
-Note: The E Miantenance release version of the library supports U-plane and C-plane only. It is ready to be used in the PTP synchronized environment.
+Note: The F release version of the library supports U-plane and C-plane only.
+M-plane is not supported. It is ready to be used in the PTP synchronized environment.
Note: Regarding the clock model and synchronization topology, configurations
C1 and C3 of the connection between O-DU and O-RU are the only
---------------------
The O-RAN Fronthaul specification defines a list of mandatory
-functionality. Not all features defined as Mandatory for O-DU are
-currently supported to fully extended. The following tables contain
+functionalities.
+
+Note: Not all features defined as Mandatory for O-DU are
+currently supported to a full extension. The following tables contain
information on what is available and the level of validation performed
for this release.
Note. Cells with a red background are listed as mandatory in the
specification but not supported in this implementation of O-RAN.

C-plane
-------
C-Plane messages are encapsulated using a two-layered header approach.
The first layer consists of an eCPRI standard header, including
corresponding fields used to indicate the message type, while the second
-layer is an application layer including necessary fields for control and
-synchronization. Within the application layer, a “section” defines the characteristics of U-plane data to be transferred or received from a
-beam with one pattern id. In general, the transport header,application
+layer is an application layer, including necessary fields for control
+and synchronization. Within the application layer, a “section” defines
+the characteristics of U-plane data to be transferred or received from a
+beam with one pattern id. In general, the transport header, application
header, and sections are all intended to be aligned on 4-byte boundaries
and are transmitted in “network byte order” meaning the most significant
byte of a multi-byte parameter is transmitted first.
Section extensions are not supported in this release.

-Additional changes may be needed on C-plane to perform IOT with O-RU depending on the scenario.
