I am getting a minor alarm every minute on my BCM400.
The message is code 326 : "This event is generated when the short-term alarm threshold has been surpassed in the Digital Trunk Interface module for the detection of controlled slip underflow. The module is in a no-new-calls state. DTCM = 0. Intervention is required to find out"
I am struggling to find out where I should be looking to try fix the problem and stop this message.
I was getting a lot of Critical Alarm 75's but after a lot of messing and after BT changed a lot of cards on our PRI this seems to have stopped. I still suspect we have some line issues though, Does anyone know what the above alarm relates to, any help is greatly appreciated.
