Embodiment Construction

[0065] The method for automatically detecting busy tone signal parameters of the voice equipment of the present invention is further described in detail below in conjunction with the accompanying drawings through specific embodiments, wherein:

[0066] Since the purpose of the present invention is to provide a method suitable for detection of on-site busy tone signal parameter data, this method is suitable for the VoIP system voice loop relay access device described below.

[0067] VoIP system voice loop trunk access devices generally have the following resources, such as figure 1 Shown:

[0068] 1. Loop relay interface;

[0069] 2. A media processing chip, which has the ability to compare tone signals. That is, by pre-setting the frequency and on-off time, it can be detected whether the input signal is the same or similar to the set parameters.

[0070] Wherein, the media processing chip refers to a DSP (Digital Signal Processor, digital signal processor) chip and the medi...

Abstract

The invention, which belongs to the technical field of automatic measuring method of relay input busy signal parameters in a loop of voice access device of VoIP (Voice over Internet Protocol) communication system, discloses a method for detecting relay busy tone of a switch loop. The method comprises the steps of connecting media processing chip resource with a relay port link of a loop receivingbusy signals; collecting detection parameters of busy tone on-off time; setting comparative parameter group of busy signals; collecting busy tone comparison result and calculating busy signal parameters according to the result to obtain an actual frequency of busy signals of a front-end processor. In the method provided in the invention, the existing software and hardware resource of the relay access device of the VoIP system voice loop is utilized to realize the effect of obtaining the most precise onsite busy tone parameter detection data easily and rapidly.

Description

technical field [0001] The invention relates to a method for detecting a busy tone of an exchange loop relay, which belongs to the technical field of detection methods of communication signal parameters, and specifically belongs to the automatic detection of busy tone signal parameters input by a loop relay on a voice access device in a VoIP communication system The technical field of the method. Background technique [0002] In the traditional telephone communication system, when both parties are in a conversation, when one party hangs up, the switch will send a busy tone to the other party. After hearing the busy tone, the caller of the other party will know that the other party has hung up and the line is in a state of hanging up, so he will hang up the call , to restore the line to idle. With the development of communication technology, especially in the application of VoIP communication system access gateway, the equipment on the user line of the exchange is not an ord...
