A bit later another group was "given" one to back up a transcontinental leased line (running bisync) and in the first week the Concords were in use continuously because (as one should plan for) the leased line had teething problems. The dialup circuit ran flawlessly. I have heard that when Codex tested their version and it proved not totally compatible with the Concord (because of an ambiguity in the CCITT spec), they actually got together and COOPERATED (!) and now at least these two vendors products will talk together. Hopefully the other vendors have followed suit (GDC, AJ, Milgo to name but a few). By the way the prices to my knowledge are in general over $3000, I think AJ is the cheapest (could be wrong of course). Some discussion about autodialler control might be in order. The vendors are going different ways. It seems to me that in an ideal world everyone would standardise on the CCITT V.25 bis standard, which covers autocalling through the (RS-232) interface for async, bisync and bit sync protocols -- but who supplies software support for this?
