ABSTRACT:
A service checking terminal is interconnected between the service lines of a telephone utility and the subscriber house circuits to protectively enclose a toggle switch and jack that are exposed upon opening of the terminal housing cover. The toggle switch is manually displaceable to a test position in which the house circuits are bypassed by a connection to the jack from the service lines to either determine the location of a fault or establish an external telephone connection.
