NEC, FCC, ANSI code for telecommunictions grounding at customer premise

Does anuyone know any codes for NEC, FCC, ANSI code for telecommunictions grounding at customer premise? We are entering into a civil case and need to find some more info on this.

Chapter 8 of the NEC pretty much covers it all. I would think that any conductors that enter a building and not following the proper code could leave you open for a lawsuit if there were a fire or injury caused by a surge or lightening.
