Embodiment 1
[0057] In this embodiment, Dual Tone Multi-Frequency (DTMF for short) is used as the media information. DTMF consists of a high frequency group and a low frequency group, each containing 4 frequencies. A high-frequency signal and a low-frequency signal are superimposed to form a combined signal, representing a number. Different high and low frequency signal superposition can realize 16 DTMF digits from 0 to 9, *, #, A, B, C, D. Figure 7 It is the process flow of the detection method of the voice chip in the home gateway device according to the embodiment of the present invention Figure 1 ,like Figure 7 As shown, the process includes the following steps:
[0058] In step S702, the circuit detection module notifies the voice media module after detecting that the voice port of the home gateway device is connected.
[0059] Step S704, the voice media module controls voice port A to generate DTMF0 (low frequency signal 941 Hz, high frequency signal 1336 Hz), and sends it to ...
Embodiment 2
[0063] In this embodiment, frequency shift keying (Frequency_shiftkeying, FSK for short) data is used as the media information, Figure 8 It is the process flow of the detection method of the voice chip in the home gateway device according to the embodiment of the present invention Figure II ,like Figure 8 As shown, the process includes the following steps:
[0064] In step S802, the circuit detection module notifies the voice media module after detecting that the voice port of the home gateway device is connected.
[0065] Step S804, the voice media module controls voice port A to generate a string of FSK data (such as 12345), and sends it to another voice port B; voice port B receives and demodulates the FSK data, modulates the information again and sends it back to voice port A ;
[0066] Step S806, the voice port A demodulates the FSK data, compares the sent and received data, and notifies the display module of the result.
[0067] Step S808, the display module displ...
