It can includes the primitive information to hinder in information.
Further, fault message is pushed to staff, may include：Obtain the mark letter of the circuit to break down
Breath；According to the identification information of the circuit, fault message is pushed to staff corresponding with the circuit.
Specifically, each staff can be responsible for different circuits, when circuit breaks down, can be only somebody's turn to do to responsible
The staff of circuit pushes fault message, improves the working efficiency of team.
It is possible to further collect information that whether all circuits break down and show corresponding pel to staff
Information facilitates staff to understand the real time status of each circuit in time.
Normal circuit can be directed to and design a set of primitive information, a set of pel letter is designed for the circuit of failure
Breath, for example, the corresponding primitive information of regular link includes the word " circuit is normal " of green, the corresponding figure of circuit of failure
Metamessage includes the word " circuit phase shortage " of red.
