That seems to be their approach...
I believe that it is the MSC because of the following:
After the strike, one of my DSM32+ was blown...when I turned the BCM on with it in, it would not power up...just a red light on the power LED
I pulled that out, and the one in there was functioning properly. When I switched the DIPs on it, I could get all of the digital lines, but in chunks, of course. They all showed the right info, and they all rang to the correct mail box...(yes call pilot was working).
Our VoIP phones worked as well...The only thing I couldn't do was get into "telephony services."
My vendor told me to upload core services (I probably have the wrong verbage, but I had to chose the Etiquette option). That told me all services were running, so an upload was not necessary.
I then ran "Initialize Universal profile." After that, the BCM would never load the OS again.
I read somewhere that NT loads services when initializing the MSC at startup, and if there are problems there, NT will not boot...I never get past the blue boot up screen...
I could still use the serial port,but when I tried the Initialization, it said that there is a bad PEC card...Isolate and replace.
This is when they recomended the new BCM at $11,000.00.
In case you haven't figgured it out, I am not a Nortel guy...I am a computer guy, though, and I have been troubleshooting for enough years to know that you should try to fix the error given before replacing the whole computer.
They did not have any PEC cards, and said that it would be 2 weeks before they could get some. I bought 2 from a vendor online ($1000.00 + S&H). Those came in, but there was no change.
The MSC card behaves the same way in a different Base services tray, so I am guessing it is a bad MSC.
My next step was to buy a new BCM because they said that the MSC was not a field replaceable part.
Unless you tell me differently, I will order the new BCM tomorrow. (5/20/07)
If I go with this as plan A, I have some questions...If I get a 4.0 system, can I take just the MSC out of it and put it in my 3.7 system...This leaves me the option to upgrade in a couple of months when I have to reprogram the whole thing anyway.
If I can do this, will there be a problem regenerating my keycodes for 3.7 with the new MSC, and then 4.0 when I upgrade?
Is there any aditional cost (other than the cost of the vendor actually generating those keycodes for me)?
Any help/advice would be greatly appreciated
