Be careful -- the lightning tests (surge) are NOTHING like the IEC standards for Europe. The AC line test is the same, but there are several telecom line tests requring 10/1000, 10/360, and 2/10us waveforms at various voltages and currents. Most tests are three terminal tests (tip & ring surged simultaneously with respect to ground), but there are also 4-wire tests (two, 3-wire pairs) and 12 pair tests. Additionally there is a 10/250us impulse used for coaxial lines that is HUGE energy.......
