Hi,
We're having an anniversary issue with our Telco - flapping Controllers E1. The isdn switched-type are verified correct and there's really no progress on their investigation.
The behaviour of the logs is it only takes 1 second of flap -down then up. I believe the impact is on the voice quality but i know that another second will bring the serial interface down which drops the call. i noticed this when i manually shutdown the controller and the first log show controller changed state to admin shut. then the next log appears after 2 seconds, serial interface change state to down.
Is there a way or any timer that can be adjusted so that it will ignore flaps of 1 second?
