John Dearing <jdearin@pacsbb.bpa.bell-atl.com> mentioned briefly the problem of "splitting pairs" when doing telephone wiring. I've fallen prey to that more than once. Interestingly, on an NT DMS switch, the lines still worked. I don't remember if it was the tip or the ring, but the new hybrid line adopted the identity of one of its parent lines. But I'm trying it right now on some plain old Michigan Bell lines and there's just a little buzz (no dialtone). Why would the DMS line still operate with a mismatched pair? Isn't each line on a separate, and (hopefully) isolated card?
