ABSTRACT:
A modem for providing both DSL and analog signal connection capability with a single RJ-11 jack via an automatic switching mechanism. The switching mechanism is controlled by software, which is responsive to user connection preference (i.e., for DSL or analog connection) and/or the detection that a DSL service is available. Dependent on whether DSL is detected on the signal line coupled to the jack and/or whether the user selects a DSL connection, the switching mechanism routes the signal received on the RJ-11 jack through either a path having the DSL modem circuitry or a path having analog modem circuitry.
