V_ON
On-State
Leakage Current
Inputs set for ringing -Measure ringing
generator current to ground.
I_RINGING
Steady-State Current* Inputs set for ringing mode.
I_SW
Surge Current*
Ringing switches on, all other switches
off. Apply ±1 kV 10x1000 μs pulse with
I_SW
appropriate protection in place.
Release Current
SW4 transition from on to off.
