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.

For some reason, lawyers seem to think that I speak for Motorola....
