Abstract
A protection device applied to a telephone line comprises at least an overload detecting device, a high temperature detecting circuit, and an enforcing on-hook means. When an abnormal over voltage or over current occurs, it can be detected by the overload detecting device. An overload signal is output to the enforcing on-hook device. Or when the temperature of a fax/modem machine raises abnormally, it can be detected by the high temperature detecting circuit. A high temperature signal is then output to enforcing on-hook device. While the enforcing on-hook device receives the overload signal or the high temperature signal, the system is on hook.
