    • A call progress analysis system is provided which is generic to any telecommunications system with which it is used due to configurable detection parameters. A signal on a channel of the telecommunications system is detected in intervals of changing frequency composition and compared to stored pattern descriptors, each of which defines a different call progress signal. In an alternative embodiment of the invention, a frequency mask is computed that is specific to a user-defined call progress analysis class. This frequency mask is used to make the DSP receiver ignore frequencies that are not part of any call progress pattern in a particular class. The frequency mask can be used in a frequency detection mode or an energy detection mode. In either mode, the detector can be customized for each channel.
    • 提供了一种呼叫进程分析系统,该系统由于可配置的检测参数而与其所使用的任何电信系统通用。 在改变频率组合的间隔中检测电信系统的信道上的信号,并与存储的模式描述符进行比较,每个模式描述符定义不同的呼叫进程信号。 在本发明的替代实施例中,计算特定于用户定义的呼叫进程分析类的频率掩码。 该频率掩码用于使DSP接收器忽略不属于特定类中任何呼叫进程模式的一部分的频率。 频率掩模可用于频率检测模式或能量检测模式。 在任一模式下,可以为每个通道定制检测器。

    • In one embodiment, a multimedia control and distribution architecture is provided. A media server/controller generates a plurality of graphics signals, each graphics signal including a separate user interface to be displayed on a particular device, such as a touch screen unit. A universal extender (UVX) coupled to the media server/controller converts and extends the graphics signals for transmission on a plurality of universal transmission pathways. Each of the plurality of devices receives a graphic signal passed thereto, displays graphics embodied in the graphics signals, and accept user input in response to the graphics signal. For example, the one or more touch screen units may accept a user touch and pass a location of the user touch back on a universal transmission pathway to the UVX, for transmission to the media server/controller. The media server/controller generates control commands and provides the control commands.
    • 在一个实施例中,提供了多媒体控制和分发架构。 媒体服务器/控制器产生多个图形信号,每个图形信号包括要在诸如触摸屏单元的特定设备上显示的单独的用户界面。 耦合到媒体服务器/控制器的通用扩展器(UVX)转换并扩展图形信号以在多个通用传输路径上传输。 多个设备中的每一个接收传递到其上的图形信号,显示体现在图形信号中的图形,并且响应于图形信号接受用户输入。 例如,一个或多个触摸屏单元可以接受用户触摸并将用户的位置传回到通向UVX的通用传输路径上,以传送到媒体服务器/控制器。 媒体服务器/控制器生成控制命令并提供控制命令。

    • A redundancy arrangement for use in connection with a programmable telecommunications switch or other device. An active hardware device, such as an ISDN packet engine card, is paired with a substantially identically configured standby device. During operation, the active device, in addition to performing all of its normal functions, also advises the standby device of all events which have an effect on the operational state of the active device. By ensuring that the standby device processes the same events in the same sequence as the active device, the standby device's operational state continuously tracks that of the active device. Should the active device malfunction or be taken out of service, the standby device becomes active without significant interruption or loss of service.
    • 用于与可编程电信交换机或其他设备相结合的冗余布置。 诸如ISDN分组引擎卡的活动硬件设备与基本相同配置的备用设备配对。 在运行期间,除了执行其所有正常功能之外,主动设备还向备用设备通知对活动设备的操作状态有影响的所有事件。 通过确保备用设备以与有源设备相同的顺序处理相同的事件,备用设备的操作状态连续地跟踪有源设备的操作状态。 如果主动设备故障或停止工作,则备用设备将在没有显着中断或丢失服务的情况下变为活动状态。
