Abstract
Abstract A surge protector circuit is installed in the middle of a standard cordset so that an OEM cordset can also provide surge protection. Telephone line surge protection (e.g., for fax and modem) and coaxial cable surge protection (e.g., for television) may be provided in the same unit.
