I have a Lucent Legend running 7.x and an MLM-007 VM module.  The MLM-007 has 4 ports.  We lost power and when the unit came back up the 4 MLM-007 ports were OOS/Busied out.  THey were on 144, 145, 146 and 147.  Dial the extension internally and you get an OOS/Busy signal.  The lowest MLM-007 VM channel would flash red. I tried our spare MLM-007 and the problem remained - not the card.

I tried everything I could think of and the only soution was to move the card from slot 6 to slot 7.  After completing the remapping of VMI-Integration and assignment of other calling group functions the VM and Auto Attendant are back in service. I still get the OOS / Busy indicator on 144, 145, 146 and 147.

Anyone have an idea of what could cause this type of an issue?

I am not sure if you tried it, but have you done a "Board Renumber"?

It also could be a bad power unit or the connection between the 2 carriers.

Is there anything else in the 2nd Carrier?

Thank you.

There are 2 modules the MLM-007 card and another 12port T/R card for classic analog phones.  I did replace the power supply and I reseated the carrier when I had the unit down for the power supply swap.

It may just be old age;)

I doubt that it's old age, I'm way past 65 and I can still work on these with a great deal of success.
