Having trouble removing a ground hum noise on in-only DID lines. I have replaced DID card, 48v pwr supply, KSU pwr supply, KSU. I have also stripped it down to 1 station card and DID only.

Just saw this post...sorry for the late reply.
did you try turning off the florcent lights in the building? if they have em. They seem to cause a lot of hum at times.

Also, you might try bonding system ground to the telco ground if they are different. This sometimes clears grounded hum isssues.
