Calls getting drop on PRI flapping

Dear friends,

I am facing prbolem with the calls drop intermitently,  below mention is the debug output

Calls getting drop on PRI flapping

Seems something its up with your E1

Do you have any other e1 besides 0/1/0? is is giving you the same problem? This could also be related to your WIC card.

Have you check with the telco?

"Dec  3 15:48:40.979 IST: %CONTROLLER-5-UPDOWN: Controller E1 0/1/0, changed state to down (AIS detected)"

is a dead give a away, Alarm Interrupted Seconds. 

(show controller e1 will give you the counters in relation to Slips, Frame errors and or AIS.  clear counters on your e1 controller and you should see these increase.    

Book it out with your telco
