That doesn't sound right. The interconnect mailbag (which is still in use for VAN interconnect though that should be invisible to the average user) has it's own acknowledgement: the IA segment.
TA1 is/was as you previously quoted, for interchange level information. There is also another sort of acknowledgement segment: TA3 (Interchange Delivery Notice). It, according to X12.5, "is exchanged between service request handlers to inform the sending service request handlers of actions taken on the interchange by the receiving service request handler. The TA3 reports the delivery and the retrieval of the interchange. The TA3 also reports the unsuccessful delivery or retrieval of the interchange and identifies the error condition." I would infer from the phraseology that a "service request handler" especially in days of yore, would be a VAN. (Of those three segments, Joe EDIUser should never be the originator nor the recipient of an IA or a TA3 segment.) Just doing my part to add to the confusion.

I don't know for sure, but I doubt if many (any?) VANs do it now. Back to you, Doug.
