Telephone Protection and Grounding

This paper gives an overview of the various types of devices most commonly used for telecommunications protection. Gas discharge and solid state devices are discussed insofar as their application to signal line protection is concerned. Their failure mechanisms, some of their shortcomings and advantages as well as the application of combinations of both types of devices is also covered. Good bonding and grounding is extremely important to the proper operation of any protection system. A discussion of the effects of improper bonding and the resultant problems is also presented.
