Abstract: A modem (12) is incorporated into a laptop computer (10) and directly connected to either a cellular phone (22), a land line (18), or both. The modem is provided with two connectors (14, 16), one for connection with a cellular phone or external DAA (24), the other for connection to a normal land line via an internal DAA (112). The modem selectively enables either the connector for the cellular phone or external DAA, or the connector for its internal DAA. The modem defaults to selecting the cellular phone or external DAA if it is connected, and only if they are not connected selects the internal DAA. These defaults can be overridden by user commands. Further, the modem can independently power down a connected internal DAA, external DAA, or cellular phone to conserve power.
