"To clarify I said new implementations."

Sure TDM will stay around but making a living off of new TDM sales is pretty much extinct - period..

I can guarantee you are not making much of a living servicing 1A2 and small TDM systems.

So put your sales hat on and upgrade the TDM sites to IP and then sell the 1A2 customers the used TDM stuff then take the 1A2 and send it to a museum then you'll make some money and you will be doing them a favor as well.
