Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] figure 1 It has already been explained in the background art.

[0021] figure 2 It is a structural block diagram of an implementation scheme for generating prompt sounds proposed by the present invention. like figure 2 As shown, the generation method of the switching system prompt tone proposed by the present invention comprises the following steps: 1. the microprocessor controls the sound source generator to produce various continuous audio signals, which are sent to the specific input time slot on the switching network sound source side by the transmission line; ②The microprocessor controls the various audio signals sent by the switching network cross-connection source generator to generate prompt tones, and sends them back to the input transmission line of the sound source generator; ③The sound source generator does not change the various promp...

Abstract

The method includes the following steps: 1) the sound source generator is controlled by microcomputer to generate various continuing sound with specific frequency and it is sent to specific input time slot at exchange network sound source side through transmission line, 2) the exchange network is controlled by the microcomputer to make cross access for various audio signal transmitted from the sound source generator for producing cue sound and to send it to the input transmission line of the sound source generator and 3) the unchanged loop back is made for various cue signal on the input transmission line by the sound source generator to generate cue sound signal which can be exchanged for sending out on the specific time slot at exchange network sound source side.

Description

technical field [0001] The invention relates to a communication exchange system, in particular to a method for generating prompt sounds required for voice communication. Background technique [0002] At present, the switching system equipment utilizes various continuous sound sources of different frequencies to output various prompt tones and test tones through the switching network, such as: dial tone, busy tone, ringback tone, No. 7 conduction tone, etc. through the intermittent ratio control. Therefore, the hardware elements required for the current implementation are: a generator for generating continuous tones of various frequencies, a discontinuous ratio controller, and a switching network. [0003] The frequency and timing of various prompt tone signals have certain rules, for example: the dial tone uses 450HZ frequency, -10dBm level, continuous tone signal; and the busy tone uses 450HZ frequency, -10dBm level, 0.35s to 0.35 s intermittent regular tone signal; in add...
