3.3.3.13 RAS Diagnosis Management (RDM)
The RDM checks if internal and external connection paths or resources of the SPI-2213 are
normal. The connection paths are roughly divided into the external path between the SPI-
2213 internal IPC path and another NE and the path between ACR and the SPI-2213.
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
y 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 SPI-2213
y Software Block Test
Ping test for main programs by processors
y RF Exchange Test
Tx path, Receive Signal Strength Indicator-based (RSSI-based) Rx path and VSWR
diagnosis
y DU-RRH Loopback Test
Support of loopback function for ‘Digital I/Q and C & M’ interface
y Backhaul performance monitoring test
Quality (packet loss, delay and delay variance) measurement for backhaul between
ACR and the SPI-2213
y Periodical online test by the operator setting
y Change of the Diagnosis Schedule
Schedule setup, such as diagnosis period, start time and end time of periodical online test
y Support of Call Trace Function
It reports the call trace information (signaling message of a specific MS, RF parameter,
and traffic statistics) to the management system via SNMPD.
y Virtual Interface (VIF) generation and removal
Generate and remove VIF based on physical link configuration in PLD
y VIF state management
Change the state of physical VIF with link failure
y RF Module Setup and Control
Transmission of the setup information required for the RF module, redundancy
structure and management of failure/status
