Abstract
A dongle for interfacing between a DSL/analog combo modem with a single RJ-11 jack and each of a DSL and analog phone outlets. The dongle in combination with the combo modem can be used in both DSL spluttered environments and DSL splitterless environments. The dongle includes a DSL microfilter, and a switch to turn the filter on and off. When the filter is off, the dongle acts as a wire router and DSL splittered signals received from a DSL outlet are passed to the DSL outer twisted pair of the dongle's RJ-11 combo jack. Analog splattered signals received from the analog outlet are passed to the analog inner twisted pair of the dongle's RJ-11 combo jack. When the filter is on, the DSL and analog signals are received on the same DSL twisted pair and are filtered by the filter so as to split out each of the DSL and analog signals. The filtered signals are then passed to each of the DSL outer twisted pair and to the analog Ainner twisted pair, respectively, of the dongle's modem RJ-11 combo jack.
