y Data Traffic Processing Function
RTC provides the data path between ACR and the SPI-2213 via the R6 data path (GRE
tunnel).
y Traffic Control Function for Handover
In handover, RTC performs the data synchronization function between serving
RAS/ACR and target RAS/ACR.
3.3.3 Operation And Maintenance (OAM) Block
OAM block manages the operation and maintenance of the SPI-2213, and it is divided as
the three shown below: EMS Interface (EMI), Main OAM and Board OAM.
Figure 3.14 OAM Software Structure
The following interface structure diagram shows the communication between OAM blocks.
Main OAM and EMI are running on the MMA-G that support master OAM.
Board OAM is running on the remaining lower processor board.
