Abstract

The present invention provides a removable telephone line surge protection circuit (104) for use by an electronic deuce such as a modem (102). The line protection circuit (104) protects the modem (102) against telephone line surges such as those caused by lightning strikes. In one embodiment of the invention, the line protection circuit (104) interfaces with test circuitry which is preferably located within the modem (102) in order to allow the modem (102) to determine if the line protection circuit (104) is still operational while the line surge protection circuit (104) is connected to the modem (102). The present invention also provides for a removable surge protection circuit that is a testable module when connected to an electronic device having automatic module test capability as presented in one aspect of the invention. The surge protection circuit also provides for status indication of its operability in order to allow device users to make a quick determination of whether or not the module is damaged.
