Abstract :
OCCASIONALLY, telephone plant and equipment are subjected to voltages and currents from external sources which are very much larger than those used in normal operation. A reasonable reserve in dielectric strength and current capacity is provided, but to cope with the more severe extraneous voltages it is necessary to provide protective arrangements.
