Hi folks,

I have a 7400 with expansion cabinet running 4.98.
Just recently, the alarm history is showing a bunch of Red Alarm and recoveries. Anywhere between 3 hours and 3 minutes between instances. Maybe once a day there is also a L2 Disconnect.

Any advice? The manual says the red alarm is a switching stack failure. Could that be caused by the carrier?

Thanks in advance.

This is almost certainly a carrier fault.

Fast forward a year and they are still experiencing this error. Carrier tried again to do "intrusive testing" and couldn't find anything. They said that errors are coming from the PBX but didn't say what they were.

Here is what they said:

HDSL span is Clean. Able to loop HLU and HRU intrusively but were unable to loop CSU.

Now, this is a TEPRI2 and the software table says with 4.99 it should be 4.28 but it has 4.29. The Samsung site doesn't list the TEPRI2 as a separate card.

Could that be it too?

Is it a external CSU , the carrier needs to be able to loop that back to assure a clean circuit

The tepri2 uses the same firmware as the tepria card.

I don't believe I've ever had a faulty tepri card.
