If my understanding is correct, you have:
- analogue CO-lines connected to PBX
- PBX and TVM have DPT-integration.

If so, then why do you try to recognize CO-line disconnection on TVM system? You have to do it at PBX side.

Also your telephony provider should to provide such services like CPC or reverse Polarity in order to you PBX would be able to recognize them.
