In addition, the line switching product in the prior art only performs line switching when a single line fails, and cannot meet the use requirements of the existing users. Therefore, how to realize the fast switching of the dedicated line of the terminal and meet the user use requirements becomes a technical problem to be solved urgently in the prior art.
Based on this, the embodiment of the invention provides a method, a device, equipment and a system for switching a special line of a terminal.

In a specific dedicated line switching system for terminals, a main conference terminal and a standby conference terminal can be set in a conference room, and both the main conference terminal and the standby conference terminal are connected to a dedicated switching device for terminals.
When in use, the main conference terminal is used as a main conference backup terminal to carry out a video conference. During the video conference, the user can be a plurality of parties, the plurality of parties participate in the video conference through respective terminals, the respective terminals are E1 terminals, and the E1 terminals are respectively connected with the terminal special switching equipment. When any E1 terminal is detected to have a preset fault, the services of all E1 terminals participating in the conference are switched from the main conference terminal to the standby conference terminal, so that the conference can continue.
In some embodiments, optionally, the preset fault includes: LOS fault, AIS fault, LOF fault. In this embodiment, the performance index of the signal is detected by crc (cyclic Redundancy check).
The LOS fault detection method may be that when the received signal has no level change, the LOS fault is determined. For 2M signals, when the levels of continuous N (10 ≦ N ≦ 255) pulse intervals are less than or equal to 35DB level lower than the nominal value, the signal is considered lost; and the signal is considered to be restored only if the levels of consecutive N (10. ltoreq. N.ltoreq.255) pulse intervals are all greater than or equal to a 9DB level lower than the nominal value. In this embodiment, it is determined whether the received signal level changes, the received signal level is compared with a preset threshold, if the signal levels of N consecutive pulses are all lower than or equal to the threshold, it is determined that an LOS fault has occurred, and if the signal levels of N consecutive pulses are all higher than or equal to the threshold, the signal LOSs is interrupted and eliminated.
In this embodiment, the AIS fault detection and setting method may be for 2M signals, and when only two or less bits of two consecutive frame signals are zero, the AIS fault is considered to occur, and when there is a frame positioning signal, three or more bits of two consecutive frame signals are zero, the AIS fault is considered to be ended.
In this embodiment, the method for detecting and setting the LOF fault may be to detect the 2M signal, and when three consecutive frames in the received signal do not have correct frame positioning information, it is determined that the LOS fault occurs. In this embodiment, it may also be set that an LOF fault occurs when the number of erroneous CRC message blocks exceeds a certain number.
In this embodiment, the switching mode of switching the service of the E1 terminal from the active conference terminal to the standby conference terminal may be active switching or automatic switching, which is not specifically limited in this embodiment.
In some embodiments, optionally, when the transmission mode of the E1 line is the PCM framing mode, switching the services of all the E1 terminals from the active conference terminal to the standby conference terminal includes: and switching the services of all E1 terminals from the main conference terminal to the standby conference terminal according to CRC4 error codes or a manual mode.

The terminal dedicated line switching device may include a main control MCU and a terminal dedicated line switcher connected through different data channels, e.g., the data channels may include CH1, CH2, CH3 and CH4, and when resources of the main control MCU are insufficient, the terminal dedicated line switcher may be utilized to realize centralized switching control. In this embodiment, a relay may be provided in the terminal dedicated line switching device, and the support service is directly connected to the main E1 channel after the device is powered off.
For example, a set of main conference terminal and standby conference terminal is placed in each conference room, and when the data transmission rate of the main conference terminal and the standby conference terminal is 2M, 4 conference rooms can be set; when the data transmission rate of the main conference terminal and the standby conference terminal is 4M, 2 conference rooms can be set; when the data transmission rate of the main conference terminal and the standby conference terminal is 8M, 1 conference room can be set.
When the E1 line currently being transmitted fails, the system can be switched to the other E1 line without damage. In this embodiment, when the main E1 line is working, the spare E1 line does not transmit the HDB3 code configuration.
