I signed my rights away for a design that I did for the telcom company
I used to work for that did u-law/a-law companding (and addition for
conferencing) in a TDM nonblocking switch for military and air traffic
applications.  It was done in pure synchronous hardware and they have
a patent application in for the whole system.  They are implementing
it in an ASIC right now.  I have to look at the legal agreement that
I signed, but I'd be willing to discuss general ideas if the original
poster has a noncommercial application in mind (I don't have the
original post).
