I'm going to have to descend from whatever foothold I used to have on
Mount Olympus, and admit that I don't understand how you could "nail
up" two bearer channels without disabling the ISDN line's capability
to carry phone calls. Were the ISDN lines used only for data service,
or could the Bearer channels be divorced while a phone call was in
progress?
