Mobile WiMAX Indoor RAS SPI-2210 System Description/Ed.07

3.3.3.13 RAS Diagnosis Management (RDM)
The RDM checks if internal and external connection paths or resources of the indoor SPI-
2210 are normal. The connection paths are roughly divided into the external path between
the indoor SPI-2210 internal IPC path and another NE and the path between ACR and the
indoor SPI-2210. In addition, it supports the on-demand test at the request of an operator
and the periodical test according to the schedule defined by the operator.
RDM Functions
 Path Test
 Internal path test: Ping test for the IPC path of the board level in NE
 External path test: Ping or traceroute test for external hosts
 Traffic path test: Test for the UDP message-based bearer path between ACR and
the indoor SPI-2210
 Software Block Test
Ping test for main programs by processors
 RF Exchange Test
Receive Signal Strength Indicator-based (RSSI-based) Rx/Tx path/VSWR diagnosis
 Loopback Test
Support of IEEE 802.3ah Ethernet loopback functions
 Backhaul performance monitoring test
Quality (packet loss, delay and delay variance) measurement for backhaul between
ACR and the indoor SPI-2210
 Periodical online test by the operator setting
 Change of the Diagnosis Schedule
Schedule setup, such as diagnosis period, start time and end time of periodical online test
 Support of Call Trace Function
It reports the call trace information (signaling message of a specific MS, RF parameter,
traffic statistics) to the management system via SNMPD.
 VIF generation and removal
Generate and remove VIF based on physical link configuration in PLD
 VIF state management
Change the state of physical VIF with link failure
 RF Module Setup and Control
Transmission of the setup information required for the RF module, redundancy
structure and management of failure/status
