摘要： A caller-ID telephone station having a caller-ID based directory of telephone numbers automatically adapts its directory to compensate for a change to the area code in which the telephone station is located. The caller-ID telephone station stores the area code for all incoming caller-ID telephone numbers along with each telephone number received. The telephone station also stores its home area code. This home area code is inputted by a user during an initialization step when the telephone station is first installed, moved to a different area code or the station's locale is changed to a different area code. In response to a request from the user for dialing a telephone number entered into the directory, the telephone station compares the stored area code received as part of the caller-ID telephone number with the stored home area code and determines from this comparison whether to include or omit the received area code as part of the dialed telephone number. In one disclosed embodiment, the received area code is included in the dialed telephone number only if the received area code and the home area code are different.
摘要翻译：具有基于来电号码的电话号码簿的呼叫者ID电话台自动适应其目录以补偿电话站所在的区号的改变。来电号码电话站存储所有来电者ID电话号码的区号以及收到的每个电话号码。电话台还存储其家庭区号。当首次安装电话台的初始化步骤期间，用户输入该家庭区号，移动到不同的区号，或者将站的区域改变为不同的区号。响应于来自用户拨打输入到目录中的电话号码的请求，电话台将作为呼叫者ID电话号码的一部分接收的存储区域码与存储的家庭区号进行比较，并从该比较确定是否包括或者作为拨打的电话号码的一部分省略接收到的区号。在一个所公开的实施例中，只有在接收到的区域代码和住宅区域代码不同的情况下，接收的区号被包括在拨打的电话号码中。

摘要： Telephone line status indication is improved by making measurements of the differential voltage across the Tip-Ring terminals of a telephone set. The telephone set is connected to a telephone line which is shared with other parallel-connected sets. The measurement of differential line voltage is made time the set changes state (i.e., between on-hook and off-hook). The maximum magnitude of one of the last three measurements is stored to represent the state, and is arithmetically averaged with the maximum magnitude of one or the last three stored for the oil-hook state to create a reference voltage. The reference voltage is updated each time the telephone set changes state and is continually compared with the present differential line voltage to determine which one is larger A light-emitting-diode on the telephone set indicates that the telephone line is in use whenever the reference voltage exceeds the measured differential line voltage.
摘要翻译：通过测量电话机的尖端端子上的差分电压来改善电话线状态指示。电话机连接到与其他并联设备共享的电话线。差分线路电压的测量是设定变化状态的时间（即在挂机和摘机之间）。存储最后三个测量中的一个的最大幅度以表示状态，并且对于油钩状态存储的一个或最后三个的最大量值进行算术平均以产生参考电压。参考电压在每次电话机改变状态时被更新，并且与当前的差分线路电压不断地比较以确定哪一个较大。电话机上的发光二极管指示电话线在每当参考电压超过测量的差分线路电压。
