摘要： A method and apparatus for increasing system functionality through a predefined interface is disclosed. Signal lines which are not used or which are not used in certain modes are connected to an interconnection device instead of being connected to an interface wherein the output of the interconnection device is connected to the interface where such lines would have been connected. The interconnection device also has a set of inputs for receiving signals from a device providing the desired functionality. A controller chooses between the two sets of inputs to control what signal lines are connected to the predefined interface. Accordingly, during certain modes of operation, the added functionality from a device whose output is being switched into the interface can be supported. In one embodiment, speaker phone capability is provided for even though the predefined PCMCIA interface does not support such capability. The disclosed design continues to maintain capability with all systems adapted to be used with such predefined interface.
摘要翻译：公开了一种通过预定界面提高系统功能的方法和装置。在某些模式下未使用或不使用的信号线连接到互连装置，而不是连接到其中互连装置的输出连接到这样的线路将被连接的接口的接口。互连设备还具有用于从提供所需功能的设备接收信号的一组输入。控制器在两组输入之间选择以控制什么信号线连接到预定接口。因此，在某些操作模式下，可以支持从其输出被切换到接口的设备的附加功能。在一个实施例中，即使预定义的PCMCIA接口不支持这种能力，也提供扬声器电话能力。所公开的设计继续保持适于与这种预定接口一起使用的所有系统的能力。
