The fault of LIU board leads several conference sites can’t connect

Publication Date:  2012-09-19 Views:  10 Downloads:  0
Issue Description
Several conference sites (in one LIU board) can’t link to the conference.
Alarm Information
Handling Process
The fault disappears after we replace the LIU board of the conference sites which can’t connect.
Root Cause
Because there are four conference sites in one LIU board, it will lead four conference sites can’t connect at the same time when the LIU board has fault. So when several conference sites can’t link to the conference, we can make sure the problem is the fault of MCU’s LIU board, not the fault of the terminal.
