摘要： A method to handle an incoming call to a target telephone that is engaged in a present call. A first signal to the target telephone indicates an incoming call, and a second signal to the calling telephone indicates that the target telephone is busy. Another method issues a first signal to a target telephone to indicate an incoming call. A ringback tone is issued to the calling telephone causing a speaker of the calling telephone to provide a ringing sound to the caller. A switch-hook signal from the target telephone indicates a desire of a user of the target telephone to place a party to the present call on hold, and to connect to the incoming call. A busy signal, is issued to the calling telephone causing its speaker to provide a busy sound if the switch-hook signal is not received by the time a variable reaches a predetermined limit.
摘要翻译：一种处理来自当前呼叫的目标电话的呼入的方法。到目标电话的第一信号指示来电，并且向主叫电话的第二信号指示目标电话正忙。另一种方法向目标电话发出第一信号以指示来电。向呼叫电话发出回铃音，导致呼叫电话的扬声器向呼叫者提供振铃声。来自目标电话的切换信号指示目标电话的用户希望将当前呼叫的一方当作保持，并且连接到来电。如果在变量达到预定极限时没有接收到切换挂钩信号，则向呼叫电话发出忙信号，导致其扬声器提供繁忙的声音。

摘要： A data terminal interface for a terminal adapter and an attached computer provides complete flexibility and control of information in a communication environment for a user. Communications between the terminal adapter and a digital network may be provided in existing digital systems, such as either the Digital Communications Protocol or Integrated Services Digital Network system, for example. The data terminal interface facilitates the exchange of information between the terminal adapter and the computer via an asynchronous data module in the terminal adapter. Through the data terminal interface, the computer is able to directly control user interface circuitry in the terminal adapter by responding to and sending unlimited information to this interface circuitry since conformance to a digital protocol is not required for message traffic between these two units. Also the data terminal interface permits all functions that a user is able to perform at the terminal adapter, such as going off-hook, pressing a button, etc., to be performed by the computer and provided to the network. Specific applications such as call screening, custom alerting and automatic call distribution are easily achieved through use of the data terminal interface.

摘要： An ISDN interface is provided on a card, which is adapted for mounting in a terminal computer and which is operable to exchange data with a terminal computer and an ISDN. The ISDN interface card includes a protocol processor that is programmable to process data encoded in accordance with a number of different protocols and a digital signal processor that is programmable for data compression, encryption and facsimile applications, and u-law and a-law conversion, among other applications. The ISDN card dynamically allocates data calls between one or two B-channels to achieve a data transmission rate of 128 kbps. A power supply with a ring generator is provided to allow for the use of an analog telephone with the ISDN card. The ISDN card is programmable to allow users to create customized screens for various call processes, and to allow for the updating of a flash ROM coupled to the protocol processor through the terminal computer and the ISDN.

摘要： This invention relates to a telephone apparatus and a method of controlling the telephone apparatus, wherein, where a calling operation conflicts with a call-receiving operation, calling processing and call-receiving processing are performed so that an intention of an operator at a calling side may be respected. A timer is caused to start to operate in response to an incoming signal detected by an incoming signal detecting unit. Where an off-hook operation is detected by an off-hook detecting unit before the expiration of a timer time set at the timer, a line control unit treats the off-hook operation as an off-hook operation for a calling operation. Where an off-hook operation is detected by the off-hook detecting unit after the expiration of the timer time, the line control unit treats the off-hook operation as an off-hook operation for a call-receiving operation.

摘要： A signaling arrangement where all terminal configuration data is stored in a switching system, but where each user terminal responds to a message from the system, defining one of the user terminal buttons as the selected call appearance at the terminal, by operating in a functional signaling mode to communicate with the system using functional messages concerning a call at the selected call appearance. Idle and ringing preference methods for use in terminating calls and auto-drop and auto-hold alternatives for use when moving from one call appearance to another are disclosed as well as methods for holding or dropping calls. Implicit and explicit conferencing methods are also disclosed.
