TL;DR: In this paper, the authors describe a device for recording the calls on the exchanger, which includes the terminal computer for sending the relevant commands, a voice mail box interface board AVM possesses the two groups of the data outgoing line for completing the voice signal conversion.
Abstract: The invention relates to the device for recording the calls on the exchanger. It includes the terminal computer for sending the relevant commands. The characteristics of the device also includes following parts. A voice mail box interface board AVM possesses the two groups of the data outgoing line for completing the voice signal conversion. A voice interface card ADP completes the voice data process .A signaling control line is utilized to transfer the PCM codes of the voice information. A voice digital line is used to complete the transfer of the controll information between the recording system and the host of the exchanger. The voice interface card is inserted in the expansion slot directly. The voice mailbox interface board is connected to the ADP as well as through the signaling control line is connected to the RS232.

TL;DR: In this article, a voice recording equipment consisting of a microphone, a voice interface card, an A/D converter, and a voice processing unit is presented, which is used to compare an intensity of the voice data with the threshold value, stops recording and reminds the user when the intensity is less than a threshold value.
Abstract: The present invention provides a voice recording equipment. The voice recording equipment includes a microphone, a voice interface card, an A/D converter, and a voice processing unit. The microphone receives voice data of a user, and transmits the voice data to the voice interface card. The A/D converter converts the voice data from analog signal to digital signal. The voice processing unit computes a threshold value according to surrounding noise environment, compares an intensity of the voice data with the threshold value, stops recording and reminds the user when the intensity of the voice data is less than the threshold value.
