Hello John & Roger: This may be nitpicky, but the new part 68/CS-03 does require a 1500V test between "All power connections" and "All telephone connections". The telecom transformer still only needs to provide 1000V of isolation however, as a 1500V barrier should be provided by the power transformer anyway.
