Abstract: A method and apparatus for remotely accessing a host computer from a remote location. The invention permits a user to remotely change a telephone number that allows the host computer to dial the user's current location. A user performs this change only after he has been strongly authenticated using a distributed user authentication protocol in addition to a simple user ID and password. This allows the user to move between locations and access the host computer, while the call-back feature protects the host computer from unauthorized intrusion. Also, a second registered user who does not have call-back authority may gain access to the host computer through a user that has call-back authority. In this case the user with call-back authority gains entry into the host computer and causes it to call the second registered user, who then enters a user ID and password to gain entry to the host computer. The present invention may be implemented in the host computer or in an interface coupled between the host computer and its modem.

Abstract translation: 一种从远程位置远程访问主机的方法和装置。 本发明允许用户远程地改变允许主计算机拨打用户当前位置的电话号码。 用户只有在使用分布式用户认证协议进行强身份验证后才执行此更改，除了简单的用户ID和密码。 这允许用户在位置之间移动并访问主机，而回叫功能保护主机免受未经授权的入侵。 此外，没有回叫权限的第二注册用户可以通过具有回叫权限的用户来访问主计算机。 在这种情况下，具有回叫权限的用户可以进入主计算机，并使其呼叫第二个注册用户，然后用户输入用户ID和密码以进入主机。 本发明可以在主计算机中或者在主计算机及其调制解调器之间的接口中实现。

Abstract: The invention relates to an integrated services digital network (ISDN) and a station for an integrated services digital network. The station comprises a feeding unit (20) for supplying a message and includes at least one station control circuit (18, 40). With the disconnect transaction the station control circuit (18, 40) is provided for inserting a message supplied by the feeding unit (20) into a disconnect information signal and for transmitting the disconnect information signal.

Abstract: Asynchronous and/or synchronous telephony protocol systems and methods may include an asynchronous signaling node (ASN) and/or a call duration time quota from a charging onset to place and complete a call based on a first device call request as received from a first user mobile device on a packet switched network. The asynchronous systems include instructions to automatically modify the telephony address with a prefix and destination address when the first device has insufficient or independent balance or upon a network exception; route the modified call signal to the ASN; and deliver and automatically disconnect the call when the call is completed. The synchronous systems are balance-independent and include instructions to automatically set the call duration time quota upon such exception, and deliver and automatically disconnect the call from the second user telephony device when the call is completed or when the call duration time quota is exceeded.

Abstract: Telephone terminals directly implement an automatic call back feature by establishing a logical channel between two telephone terminals when a calling telephone terminal is unable to complete a call to a called telephone terminal. Via the logical link, the called telephone terminal communicates to the calling telephone terminal any change in state that is related to its ability to receive a call. When both telephone terminals are idle, the calling telephone terminal recalls the called telephone terminal to set up a call. The logical link is established on user-user temporary signaling or D channel facilities of ISDN links. Since the interconnecting networks are not part of providing the automatic call back service, the telephone terminals can be interconnected by any combination of telephone networks that provide ISDN service.

Abstract translation: 当主叫电话终端无法完成对被叫电话终端的呼叫时，电话终端通过在两个电话终端之间建立逻辑信道来直接实现自动回叫功能。 通过逻辑链路，被叫电话终端与主叫电话终端通信与其接收呼叫能力有关的状态变化。 当两个电话终端空闲时，主叫电话终端调用被叫电话终端建立呼叫。 逻辑链路建立在用户用户临时信令或ISDN链路的D信道设备上。 由于互连网络不是提供自动回叫业务的一部分，电话终端可以通过提供ISDN服务的电话网络的任何组合互连。
