    • A modem is incorporated into a laptop computer and directly connected to either a cellular phone, a land line, or both. The modem is provided with two connectors, one for connection with a cellular phone or external DAA, the other for connection to a normal land line via an internal DAA. 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.
    • 调制解调器被结合到笔记本电脑中并且直接连接到蜂窝电话,陆线或两者。 调制解调器提供两个连接器,一个用于与蜂窝电话或外部DAA连接,另一个用于通过内部DAA连接到正常的陆线。 调制解调器选择性地启用用于蜂窝电话或外部DAA的连接器,或用于其内部DAA的连接器。 调制解调器默认选择手机或外部DAA(如果已连接),并且只有在未连接时才选择内部DAA。 这些默认值可以被用户命令覆盖。 此外,调制解调器可以独立地断开连接的内部DAA,外部DAA或蜂窝电话以节省电力。
