There are E1 PCM alarms because the idle E1 links are not connected to transmission equipment

Publication Date:  2012-07-24 Views:  36 Downloads:  0
Issue Description
When we reboot system, after the system restores, there are E1 PCM alarms in host and BMS every time.
Alarm Information
Null
Handling Process
You can make a local loop by self-loop cable for these E1 links. Then the physical status will be up, there will not any E1 PCM alarm generated.
Root Cause
When the system initializes, it will check the E1 links status, if the physical status is down, it will generate the E1 PCM alarm. Then we should check the E1 links according to the alarm. So it is not a problem. But customers do not want to see this alarms in host and BMS. How to solve it?
Suggestions
Null
