Abstract
A telephone line overvoltage protection method and assembly are provided. The telephone line overvoltage protection assembly includes a telephone line station protector having at least first and second threaded arrester wells coupled to a telephone line pair to be protected, an adapter base, and a plug-in type telephone line overvoltage protector module mounted to the adapter base and having TIP, RING and ground pins. The adapter base includes TIP, RING and ground sockets for removably receiving the TIP, RING and ground pins of the overvoltage protector. First and second mounting legs project from the adapter base for being fixedly inserted into the first and second threaded arrester wells. First and second electrodes extend from the first and second mounting legs for electrical connection with the TIP and RING sockets and the arrester wells. A grounding clip on the adapter base is coupled to the ground socket and is coupled to the first and second bushings when the first and second mounting legs are inserted into the first and second arrester wells.
