NT1R20AB OPS Line Card and Disconnect Supervision

NT1R20AB OPS Line Card and Disconnect Supervision

NT1R20AB OPS Line Card and Disconnect Supervision

(OP)
I have a NT1R20AB OPS Station card and am trying to get hook flash disconnect supervision working. I *think* I have the TNs configured properly with the most important bit being FTR ISP. Below is an example TN.

However, what I am finding is that disconnect supervision is only working on calls received by the station and not on calls placed by the station. I've had this same configuration via a Lineside T1 card connected to a channel bank and disconnect supervision worked with placed and received calls fine. I did try removing FTR OSP in case battery reversal disconnect supervision was conflicting with hook flash disconnect supervision but that did not make any difference.

I should also mention that these TNs were MOVed from a Lineside T1 to the OPS Line Card. Just in case something might've been in a funky state I went as far as power cycling the system...no change. I have not tried OUTing and re-creating a TN.

I'm assuming the OPS line card will work the same as the Lineside T1, but maybe I have something misconfigured...or my assumption is bad!

Any ideas?
