and S2, when the VC container time slot has a loopback, the EOS service has a loopback.
In the embodiment of the invention, the time slot of an SDH plane VC container in an EOS service is subjected to loopback detection;
firstly, in step S1, inserting a preset trace byte code into the VC container time slot, wherein in the actual operation process, the preset trace byte code is modified by the existing 16-byte trace byte, selecting the 16-byte trace byte, and inserting a preset mark code into the idle byte to obtain a preset trace byte code;
inserting a preset trace byte code into the VC container time slot, wherein after the VC container time slot receives the preset trace byte code, when the VC container time slot works subsequently, if the VC container time slot is looped back, the trace byte code sent by the VC container time slot and the received trace byte code are consistent next time, namely the VC container time slot contains preset mark codes, and the source end and the receiving end in the sent and received trace byte codes are both the VC container time slot, so that the VC container time slot can be judged to have the loop back;
because the time slot of the VC container in the SDH plane is a component of the EOS service, when the time slot of the VC container has loopback, the EOS service also has loopback.
It should be noted that the conventional trace bytes are of two types, namely 1 byte and 16 bytes, and the embodiment of the present invention is modified based on the trace bytes of 16 bytes.

the second detection of the embodiment of the invention is different from the loopback detection layer of the first detection, and the loopback condition is detected from different layers, so that the accuracy of loopback detection is improved.
It should be noted that, the operation steps of the EOS service loopback detection method combining the first detection and the second detection at this time are as follows:
a1, first detection: inserting a preset trace byte code into the VC container time slot, detecting whether the next time the VC container time slot is sent and the received trace byte code is consistent, if so, looping back the VC container time slot;
a2, second detection: respectively receiving Ethernet characteristic values of the transmitting and receiving directions of the VCG in the Ethernet, comparing the Ethernet characteristic values of the transmitting and receiving directions, and if the Ethernet characteristic values are matched, looping back the Ethernet;
a3, when any loopback exists in the time slot of the VC container or the Ethernet, the loopback exists in the EOS service;
the first detection is used for detecting whether the VC container time slot has a loopback, the second detection is used for detecting whether the Ethernet has a loopback, and when any one of the two loops exists, the EOS service has a loopback.

the operation is mainly used for improving the accuracy, and avoiding the error of the first detection in a single time, thereby causing the error judgment of the whole loopback detection.
In another implementation manner of the embodiment of the present invention, the second detection specifically includes the following steps:
b1, respectively establishing cache table items in the transmitting and receiving directions of the VCG of the Ethernet;
b2, receiving the Ethernet characteristic values of the receiving and sending directions by using each cache table entry;
b3, comparing the Ethernet characteristic values of the receiving and sending directions, if matching, the Ethernet has a loop back;
in actual operation, the ethernet characteristic value in the transceiving direction is obtained by using the cache table entry, and each message characteristic information received from the VCG of the ethernet in the relative direction is detected in the stored table entry, for example, if a message is received from one direction of the VCG of the ethernet, the characteristic value of the message is retrieved from the table entry in the other direction, and when matching exists, that is, consistency exists, the ethernet has loopback;
in addition, if the characteristic value of the received message can be detected in the opposite table entry, the loopback of the Ethernet exists, and the characteristic value of the message is not put into the table entry in the local direction any more.
In another implementation manner of the embodiment of the present invention, the second detection further includes the following steps:
and creating an aging timer, and deleting the Ethernet characteristic values when the storage time of the Ethernet characteristic values in each cache table entry exceeds the preset storage time.
It should be noted that, no matter in the first detection, the second detection, or the final EOS service loopback judgment step, when the loopback exists, the alarm operation can be performed, so as to remind the operator of the loopback.
In another implementation manner of the embodiment of the present invention, the first detection further includes the following steps:
suspending TIM alarm work of the SDH network;
it should be noted that TIM alarm work, specifically trace byte mismatch alarm, is performed when trace bytes expected to be received are not matched with trace bytes actually received, so that if TIM alarm work is started and first detection is performed, the VC container time slot next time when the sent trace byte codes are consistent with the received trace byte codes, the VC container time slot has loopback, alarm reporting is performed, and when the sent trace byte codes are inconsistent with the received trace byte codes, TIM alarm work is performed;
in other words, no matter whether the next trace byte code sent and received by the VC container time slot is consistent, there will be an alarm, but the corresponding problems of the alarm are different, so the TIM alarm work of the SDH network needs to be suspended, and interference to the staff is avoided.
In another implementation manner of the embodiment of the present invention, the first detection further includes the following steps:
and when the time slot of the VC container has a loop, inserting an AIS alarm in the time slot of the VC container.

based on the lcas functional characteristics, the bandwidth can be adjusted, and then a preset trace byte code is inserted into the VC container time slot.
It should be noted that the method should also have the following functions in order to ensure the implementation of the overall scheme:
the trace bytes of a VC container of the SDH can be reformed, not only the content of the sent trace bytes can be configured, but also the content of the received trace bytes can be obtained;
