摘要： A method and apparatus for achieving crypto-syncronization in a packet data communication system employing cryptographic communications. In a transmitter, a state vector is incremented at a predetermined rate and is provided to an encryption module. The encryption module uses the state vector to sequentially encrypt the data frames. During periods of frame dropping prior to encryption, the state vector is disabled, thereby allowing for sequential encryption of the data frames. In a receiver, during a frame dropping condition, the state vector is advanced in proportion to the number of frames dropped. During an underflow condition at the receiver, the state vector is disabled for the duration of the underflow condition, and enabled once the underflow condition has passed.

摘要： A method and apparatus for controlling various functional elements in a digital telephone system using state determination from an echo canceller. An echo canceller is used to evaluate which one of five talk states two speakers are engaged in during a telephone conversation. This state determination information is used to control a tone detector function, a noise suppressor function, an adaptive equalizer function, a transmission mute function, and a vocoder encoder function within a vocoder. During the talk state where the far-end speaker is active and the near-end speaker is inactive, the echo canceller provides a signal which disables background noise estimates from being performed in the noise suppressor and the vocoder encoder. The same signal is used to disable the tone detector and to enable the transmission mute function during this talk state.

摘要翻译： 一种使用来自回波消除器的状态确定来控制数字电话系统中的各种功能元件的方法和装置。 回声消除器用于评估在电话交谈期间两个扬声器参与的五个通话状态中的哪一个。 该状态确定信息用于控制声码器内的音调检测器功能，噪声抑制器功能，自适应均衡器功能，传输静音功能和声码器编码器功能。 在远端扬声器有效并且近端扬声器无效的通话状态期间，回声消除器提供禁止在噪声抑制器和声码器编码器中执行背景噪声估计的信号。 相同的信号用于禁用音调检测器，并在此通话状态期间启用传输静音功能。
