Mobile WiMAX Outdoor RAS SPI-2210 System Description/Ed.05

3.3.3.13 RAS Diagnosis Management (RDM)

The RDM checks if internal and external connection paths or resources of the outdoor SPI-

2210 are normal. The connection paths are roughly divided into the external path between

the outdoor SPI-2210 internal IPC path and another NE and the path between ACR and the

outdoor 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: Traceroute test for external hosts

 Traffic path test: Test for the UDP message-based bearer path between ACR and

the outdoor SPI-2210

 Software Block Test

Ping test for main programs by processors

 RF Exchange Test

Tx path, Receive Signal Strength Indicator-based (RSSI-based) Rx path and 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 outdoor 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
