CHAPTER 2. Overview of Outdoor SPI-2331

2.5 Interface between Systems

2.5.1 Interface Structure

The outdoor SPI-2331 interfaces with another RAS and ACR as shown in the figure below:
Interface between Outdoor SPI-2331 and MS
The outdoor SPI-2331 interfaces with an MS according to the IEEE 802.16e radio access
standard to exchange the control signal and the subscriber traffic.
Interface between Outdoor SPI-2331 and ACR
The interface between an ACR and the outdoor SPI-2331 in the same ASN is R6 and its
physical access method is FE. The R6 is the interface between ACR and RAS defined in
Mobile WiMAX NWG and is composed of signaling plane(IP/UDP/R6) and bearer
plane(IP/GRE).
Interface between Outdoor SPI-2331 and WSM
The interface between the outdoor SPI-2331 and the WSM complies with SNMPv2c or
SNMPv3c of IETF standard, SFTP and Samsung's proprietary standard and its physical
access method is FE.
