Detailed Description
The present invention provides a FXS port control method, a storage medium, and an access network device, and the present invention is further described in detail below to make the purpose, technical solution, and effect of the present invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a VoIP system, DTMF (dual-tone multi frequency) is a commonly used dialing method, when the minimum threshold detection value of DTMF is set to-32 dbm0, DTMF can be correctly checked in the range of 0-3.6km, but when the DTMF is used in a long distance, the threshold value of the DTMF detector needs to be manually configured from-32 dbm0 to-48 dbm0, so as to meet the long-distance use requirement, and the DTMF needs to be manually configured each time, which is inconvenient to use.
Based on the technical problems in the prior art, the invention provides an FXS port working method, as shown in fig. 1, which includes the steps of:
s10, monitoring the running state of the FXS port on the access network equipment in real time;
and S20, if the first FXS port works normally in the called mode and works abnormally in the calling mode is monitored, and the second FXS port works normally in both the calling mode and the called mode, automatically adjusting the lowest threshold value of a first DTMF threshold detector, wherein the first DTMF threshold detector is used for detecting DTMF signals when the first FXS port dials.
In this embodiment, by monitoring the running state of the FXS port on the access network device in real time, when it is monitored that the first FXS port works normally in the called mode and abnormally in the calling mode, and the second FXS port works normally in both the calling mode and the called mode, when it is determined that the subscriber line connected to the first FXS port is too long, the lowest threshold value of the first DTMF threshold detector is automatically adjusted downward, so that the FXS port can be in a normal running state. The embodiment effectively solves the technical problem of inconvenient use caused by the fact that the lowest threshold value of the DTMF detector needs to be manually configured when the subscriber line is too long.
In some embodiments, before the step of monitoring the operation state of the FXS port on the access network device in real time, the method further includes: detecting the running mode of an FXS port on access network equipment; if the FXS port receives a ringing signal and an off-hook signal in sequence, judging that the FXS port is in a called mode; and if the FXS port directly receives an off-hook signal, judging that the FXS port is in a calling mode.
In this embodiment, when it is determined that the FXS port is in the calling mode, the FXS port includes processes of off-hook, dialing, talking, and on-hook, and the FXS port records off-hook time, talking condition, and on-hook time; when the FXS port is judged to be in the called mode, ringing, off-hook, conversation and on-hook processes are included, and the FXS port also records off-hook time, conversation condition and on-hook time; in the called mode, before the off-hook action, a ringing step is carried out, so that whether the FXS port receives the ringing signal or not can be judged to determine whether the FXS port is in the calling mode or the called mode currently.
In some embodiments, when the first FXS port is in the calling mode, detecting a DTMF signal when the first FXS port dials through the first DTMF threshold detector, and counting the number of detections; and if the first DTMF threshold detector does not detect the DTMF signal for more than the preset times, judging that the first FXS port works abnormally in the calling mode.
In some embodiments, the predetermined number of times is 3. In this embodiment, the situation that the telephone is unintentionally touched to cause off-hook and no dialing can be reasonably eliminated by setting the predetermined number of times to 3, and the behavior of adjusting the minimum threshold value of the DTMF detector under the abnormal use condition is avoided.
In some specific embodiments, the FXS port is used to record the working condition of the telephone, and distinguish the calling and called modes according to the working condition, and in the calling mode, the FXS port counts the received DTMF data, the off-hook time and the on-hook time; in a called mode, the FXS port counts voice energy, off-hook time and on-hook time, when the FXS port does not count DTMF data in a calling mode, whether the voice energy counted by the FXS port is abnormal or not is immediately detected in the called mode, if the voice energy counted by the FXS port is normal in the called mode, the condition that the DTMF data is counted by other FXS ports on the same network access device is continuously detected, if the condition that the DTMF data is counted by other FXS ports on the same network access device is normal, the condition that the DTMF data is counted only by the FXS port is abnormal is indicated, the fact that the DTMF data cannot be counted due to overlong subscriber line is judged, the lowest threshold value of the DTMF detector is automatically adjusted, if the statistics that all other FXS ports on the same network access device are abnormally operated is detected, the fact that the network access device is in fault is indicated, and the network access device is checked, and in the called mode, if the voice energy counted by the FXS port is abnormal, checking the telephone and the network access equipment.
In this embodiment, in the calling mode, when the FXS port does not count the DTMF data, the situation of the voice energy counted by the FXS port in the called mode is first determined, it is determined that the port works normally as the called party, the situation of the counted DTMF data of other FXS ports of the same network access device is detected, if the counted DTMF data of other FXS ports is normal, the value of the voice energy of the DTMF port that cannot be detected is lower than the value of the voice energy of the DTMF-detectable port, it is determined that the DTMF signal cannot be counted due to an excessively long subscriber line, and the lowest threshold value of the DTMF detector is automatically adjusted. The embodiment can automatically process the condition that the FXS port cannot count DTMF signals in a calling mode, and automatically divides the faults into two types, wherein one type is to remind a telephone or network access equipment to check due to the fact that hardware fails, and the other type is to automatically adjust the minimum threshold value of a DTMF detector due to the fact that the FXS port cannot count DTMF data due to the fact that a subscriber line is too long.
In some embodiments, the FXS port statistics of voice energy is performed over a DSP channel. In this embodiment, the voice energy is detected through the enabled DSP channel, and when the voice energy can be detected, it indicates that the hardware path is not faulty, whereas when the voice energy cannot be detected, it indicates that the hardware path is faulty.
In some embodiments, the lowest threshold value of the DTMF threshold detector is adjusted according to the amount of voice energy counted by the FXS port in the called mode. In this embodiment, the minimum threshold of the DTMF threshold detector is adjusted and controlled by the size of the voice energy counted by the FXS port in the called mode, when the detected voice energy is small, it proves that the subscriber line is long, the minimum threshold should be set to a relatively low value, for example, -40dbm0 to-48 dbm0, when the detected voice energy is large, the minimum threshold should be slightly lower than the currently set minimum threshold, for example, -34dbm0 to-38 dbm 0.
In some embodiments, the minimum threshold value ranges from-32 dbm0 to-48 dbm 0.
In some embodiments, if it is monitored that the FXS port works abnormally in both the called mode and the calling mode, it is determined that the hardware of the access network device fails. The hardware failure comprises a media board failure and an FXS user board failure.
In some embodiments, there is further provided a storage medium having stored therein a plurality of instructions adapted to be loaded by a processor and to perform the steps of any of the above described methods of controlling an FXS port.
In some embodiments, an access network device is also provided, wherein, as shown in fig. 2, the access network device comprises a processor 10 adapted to implement instructions; and a storage device 20 adapted to store a plurality of instructions adapted to be loaded by the processor 10 and to perform the steps of a method of controlling the FXS port according to the invention.
In summary, the present invention designs an FXS port working method, which can automatically process the condition that the FXS port cannot count DTMF data in the calling mode, and automatically divide the fault into two types, one is because hardware fails, and the other is because the FXS port cannot count DTMF data due to an excessively long subscriber line, and then automatically adjust the minimum threshold value of the DTMF detector.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
