Hmm. Are you sure your TA requires a synchronous stream? While V.110 is a rate adaption protocol, it is typically used to convert an asynchronous stream to a synchronous 64K stream (for transport over a B channel). Example, the TA would take in an async stream from your DTE at 19.2 Kbps, use V.110 to turn the data into a 64 Kbps stream, and place it on the B channel. It seems that your TA should probably do this.
