You might give it a try to ask your question over at the Telephone Tec Talk board-
http://www.sundance-communications.com/cgi-bin/ultimatebb.cgi There are a couple of Canadian guys there that are regular users of BIX and I think it would be more on topic there than on an electrical board such as this.
As far as I know that link I gave you is the only manufacturer of BIX products but I could be wrong.
