摘要： A gateway includes a network interface and an apparatus for detecting predetermined tones The apparatus includes an input to receive a signal transmitted over the network interface, a frequency divider to divide the signal into two different components, each component being associated with a different frequency sub band, wherein each frequency sub band is selected to include a predetermined frequency of a predetermined tone, a frequency discriminator to determine frequencies of tones in the components, and a decision logic block to provide an indication that a first predetermined tone has been detected when a first determined frequency of a first tone in a first component corresponds to a first predetermined frequency of the first tone.

摘要： An apparatus for detecting one or more predetermined tones transmitted over a communication network, each predetermined tone having a predetermined frequency, comprises a data memory for storing data including the predetermined frequency of each of the one or more predetermined tones, an input for receiving a signal transmitted over the communication network, and a frequency divider for dividing the received signal into at least two frequency sub bands so as to provide at least two components of the received signal in different frequency sub bands. The different frequency sub bands are selected based on the predetermined frequencies of the one or more predetermined tones. A frequency discriminator is arranged to determine a frequency of each tone in the at least two components and a decision logic block is arranged to provide an indication that a predetermined tone has been detected when the determined frequency of a tone in a component corresponds to the predetermined frequency of one of the one or more predetermined tones.
摘要翻译：一种用于检测通过通信网络发送的一个或多个预定音调的装置，每个具有预定频率的预定音调包括用于存储包括一个或多个预定音调中的每一个的预定频率的数据的数据存储器，用于接收信号的输入通过通信网络发送的分频器，以及分频器，用于将接收到的信号分成至少两个频率子频带，以便在不同的频率子频带中提供接收信号的至少两个分量。基于一个或多个预定音调的预定频率来选择不同的频率子频带。频率鉴别器被设置为确定至少两个分量中的每个音调的频率，并且确定逻辑块被配置为当所确定的分量中的音调的频率对应于预定的音调时，提供已经检测到预定音调的指示一个或多个预定音调之一的频率。
