Remove Digital Link

[jenkinszell]

Hello we had a T1 connection to an old NEC that has been removed (from Mitel 3300).  I removed the ARS Route, ARS Digits Dialed, Trunk Group, Digital Trunks, Digital Link Descriptor, T1-D4/E1 CAS DID and E and M.  But the Digital Link PLID still exists, I can clear it but cannot delete it.  System is in alarm for DSU msg link.  What am missing, I'm sure it is staring me in the face, but cannot see it? 

Thanks

Check under Hardware -> Framers and un-assign the interface type if it's still there.

Of course, I knew I missing something.  Thanks, it's all clear now.
