3.3.3.11 Common Event Router (OER)/Common Event Viewer (OEV)

The OER/OEV manages the event history as the text format. The OER/OEV transmits the

information on all the events received from the OAM applications to the related agent

(OAGS, WebEMT), and creates and saves the history file of the daily/hourly events, and

displays the log contents on the operator window (IMISH) in real time.

OER Major Functions

y Event transmission

OER/OEV transmits the information on the generated event to the OAGS or the

WebEMT block, thus it enables to report it to the management system.

y Creating and saving the event history file

OER/OEV creates and saves the daily/hourly event history file in its own nonvolatile

storage as the 1 Mbyte maximum size.

y Event display

OER/OEV displays the event generated in the SPI-2213 on the operator window

(IMISH) in real time.
