Residental NID Boxes

[mpowell]

Doe anyone know a good link that describes the wiring for various residental NID boxes? A freind had ISDN plus two phone lines, they dropped the ISDN for DSL. Now they want the jack used for ISDN for a regular phone. I just wanted to make sure the "pin-out" of the lines is correct when I change it.

Thanks,
