Protocol Errors

[frecomm]

I have a BCM-400 4.0 with PRI that had been operating great for years. After a power outtage, it has been having Protocol errors and dropped calls. The CLID will read 1 or 2001 or some other combination of 0's 1's and 2's and then the call drops or there is nothing there when answered. I read on the forum here, that software update 17 might resolve this issue. However, I have been unable to find this update anywhere, including Avaya support. Does anyone know where to find this update? Or has anyone seen this error before?
Thanks in advance.

Change the power unit.
It might have caused a problem and giving out lower voltages.

I had one that actually only affected the Pri card module .
It kept clicking .
I changed the module and still had the same problem.
I changed the power unit and all fixed. And working.
