Ed, I think Beldon was just a typo.
It was originally Nordx, based in Canada, so it's still more prevalent there.
Belden bought CDT and got rid of most of the individual company names.
Nordex was formed from the sale of Nortel's cable division so that's why they had Bix etc.
And I agree that Beldon is a typo, never seen a company called that selling telephone stuff in Western Canada.
