The NEC covers Grounding and Bonding from a SAFETY standard.

BICSI, EIA/TIA/ANSI cover Grounding and Bonding from a PERFORMANCE standard.

B I G difference.

Grounding in the era of Steppers, XBar, 1A2 and the like was a lot easier then now. 2 or 3 volt imbalance won't effect a 1970 era phone system. But a "modern" VOIP system? It would hose it.

I worked for a company that was contracted by NBC to provide Telephone service to the Olympics in Russia (1984?). We opted to provide a XBar, because the question was raised whether a "new" electronic system (NEAX 22L) would function with the poor quality Russian infrastructure. Grounding was a major concern. Of course, because of Afghanistan we never got to do the job.
