2.4 Interface between Systems

Interface Structure

The SPI-2L10 interfaces with another RAS and ACR as shown in the figure below:

Figure 2.2 Structure of SPI-2L10 Interface

y Interface between SPI-2L10 and MS

The SPI-2L10 interfaces with an MS according to the IEEE 802.16 radio access

standard to exchange the control signal and the subscriber traffic.

y Interface between SPI-2L10 and ACR

The interface between an ACR and the SPI-2L10 in the same ASN is R6 and its

physical access method is GE/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).

y Interface between SPI-2L10 and WSM

The interface between the SPI-2L10 and the WSM complies with SNMPv2c or

SNMPv2c/SNMPv3c of IETF standard, FTP/SFTP and proprietary standard of

Samsung and its physical access method is GE/FE.

y Interface between SPI-2L10 and GM

The interface between the SPI-2L10 and GM is IEEE 1588 protocol (PTP) and its

physical access method is GE.This interface is for data and control signal for system

synchronization.
