How's this for productive? When I unplug my TVA, the green light blinks. When I plug it into my TA-824, it still blinks...I guess it's not integrated, because when I plug it back into my TAW it goes solid.
So, that tells me that you're either missing the assignment of ports on the TA, or the APITS integration on the TVA.
Pretty much what the other two posters said.
