    • An intelligent information router system comprising a telephony controller coupled to a private branch exchange through a link interface. The telephony controller may communicate with a handle manager and a script interpreter engine. The telephony controller may receive information from the link interface regarding telephone calls being placed to the private branch exchange. The telephony controller may initiate actions with the script interpreter engine that access information stored in a database through a database controller. In response to action of the script interpreter engine, the telephony controller may instruct the private branch exchange to route the call to an appropriate location within a company depending on the information received by the private branch exchange through automatic transmission of data or interaction with the calling party.
    • 一种智能信息路由器系统,包括通过链路接口耦合到专用小交换机的电话控制器。 电话控制器可以与句柄管理器和脚本解释器引擎通信。 电话控制器可以从链路接口接收关于正在发送到专用小交换机的电话呼叫的信息。 电话控制器可以通过数据库控制器来访问存储在数据库中的信息的脚本解释器引擎发起动作。 响应于脚本解释器引擎的动作,电话控制器可以指示专用小交换机将呼叫路由到公司内的适当位置,这取决于专用分支交换机通过自动传输数据或与呼叫的交互接收到的信息 派对。

    • Methods and systems for synchronizing wireless transmission of data packets is provided. Signals having a data packet frame format including a preamble (with a pattern of symbol sequences) and data are received, and patterns of symbol sequences are correlated. A first metric can be calculated that is a ratio of an average of the correlation values and an average of a power of the signals. A second metric can be calculated that defines an average of a power of noise in the signals. The methods include determining an approximate division of the preamble and data in the data packet of each signal based on the first and second metrics. The methods further include determining a cross-correlation between versions of a transmitted signal to produce a number of peaks equal to a number of transmit antennas, generating a third metric based on combinations of cross-correlations, and identifying a position of a maximum peak within the third metric as a fine timing offset amount.
    • 提供了用于同步数据分组的无线传输的方法和系统。 具有数据包帧格式的信号被包含前导码(具有符号序列的模式)和数据,并且符号序列的模式相关。 可以计算出相关值的平均值与信号的功率的平均值的比率的第一度量。 可以计算定义信号中噪声功率的平均值的第二度量。 所述方法包括基于第一和第二度量来确定每个信号的数据分组中的前导码和数据的近似除法。 所述方法还包括确定发射信号的版本之间的互相关,以产生等于多个发射天线的数量的峰值,基于互相关的组合产生第三度量,以及识别最大峰值的位置 第三度量作为精确的定时偏移量。

    • A system and method of retrieving customer records regardless of area code change affecting customer telephone numbers stored in customer records is provided. The method begins by providing an area code changes user interface on a system user display, which is configured to accept area code changes input by the system. Area code changes, which include actual area codes and old area codes are input using the interface. Next, each input area code change is stored in an area code changes memory. An ANI string corresponding to an incoming telephone call is then received and at least one customer record database is searched to identify any call records that include a telephone number corresponding to the ANI string. If no customer records are identified, then the area code changes memory is searched to identify if the ANI string includes an area code corresponding to an actual area code stored in the area code changes memory. If an actual area code match is found, then the ANI string is modified by replacing the area code included in the ANI string with the old area code corresponding to the actual area code stored in the area code changes memory. The customer record database search is then repeated until there are no more actual area codes stored in the area code changes memory that correspond to the area code included in the ANI string.
    • 提供了一种检索客户记录的系统和方法,而不管影响客户记录中存储的客户电话号码的区域代码变化。 该方法开始于在系统用户显示器上提供区域代码改变用户界面,其被配置为接受由系统输入的区域代码改变。 使用界面输入区域代码更改,其中包括实际区域代码和旧区域代码。 接下来,每个输入区域代码改变被存储在区域代码改变存储器中。 然后接收对应于进入电话呼叫的ANI字符串,并且搜索至少一个客户记录数据库以识别包括与ANI字符串对应的电话号码的任何呼叫记录。 如果没有识别到​​客户记录,则搜索区域代码改变存储器以识别ANI字符串是否包括与存储在区域代码改变存储器中的实际区域代码相对应的区域代码。 如果找到实际区域码匹配,则通过将包含在ANI字符串中的区域代码与对应于存储在区域代码改变存储器中的实际区域代码的旧区域代码进行修改来修改ANI字符串。 然后重复客户记录数据库搜索,直到在与ANI字符串中包括的区域代码相对应的区域代码改变存储器中没有更多的实际区域代码。
