Out a Phantom MSDL Card from a Phantom Cabinet

[robl3000]

I recently received a second-hand Option 11c and have been OUTing the previous owner's configuration. However, there appears to have been a MSDL card in a second cabinet. Unfortunately, I only have the main cabinet.

Trying to out the DCH on the MDSL in LD 17 tells me that I have an SCH5589 "Cannot out application from MSDL card, as this is the last application, the MSDL card has to be disabled."

LD 96
.stat msdl
MSDL 13: SYS DSBL - NOT RESPONDING

So the card is obviously disabled. It doesn't even exist as this is now a single cabinet system.

Does anyone have any pointers how to out this phantom menace? Any help would be greatly appreciated!

UPDATE

It's gone! I'm still not 100% what exactly I did, but with a few suggestions from a friend, some card swapping, and lots of attempts to disable & re-enable the loops & d-channel, I was able to out everything left in regards to this card.

To remove the MSDL config as you suggested... I think that the answer is that you would have had to remove the programming (out) the service that it was associated with eg: an E1 service. No service, no need for the MSDL, therefore you can out it.
