As I was taught in phone school 21 years ago, 1 Ren is the amount of current needed to ring a Western Electric single line telephone with a mechanical bell. The phone company was required to provide 5 Ren on a line.

I would see if you can call repair and get through to a test board operator who would probably know someone there who would know.

I've not heard of a B Ren. Someone working in the switch office of a LEC or CLEC should be glad to help you.
