If a fault current forces TIP and/or RING to a more negative voltage than VS, current is conducted through the trip circuit. When the specified trip current level is reached, transistors PNPN1 and/or PNPN2 will turn on and "crowbar" the majority of the current to ground. If similar pulses force TIP and/or RING to a more positive state than ground, diodes D1 and/or.
