The disclosed embodiments include a surge protection module that includes an integrated signal splitter configured to combine a signal from a DSL tip wire with a signal from the POTS tip pin to generate a DSL/POTS tip output signal, and combine a signal from a DSL ring wire with a signal from the POTS ring pin to generate a DSL/POTS ring output signal. The integrated signal splitter is configured to be in electrical communication with an overvoltage protection component and to output the DSL/POTS tip output signal and the DSL/POTS ring output signal to the overvoltage protection component.
