There is currently no Protocol testing required for ISDN in the US and Canada, but of course one should take a good look anyway :)
On a related note, does anyone have their ear closer to the ground regarding when the Type B surges(which I lovingly refer to as "not >quite< so hazardous voltages") will become part of Part 68? Does anyone have tricks up their sleeve for how the might modify their telecom circuits to survive Type B surges? Take out the fuse, for example, and use PTC resistors? Other Thoughts?
